HISTORY
THE ROCK ON WHICH
THE STORM WILL BEAT: FORT ADAMS AND THE DEFENSES OF NARRAGANSETT BAY
Theodore L. Gatchel
The
forces of nature that gave the settlers of Rhode Island one of the finest
natural harbors in the world, Narragansett Bay, also presented them with
a military challenge. Part of the challenge was to prevent an enemy fleet
from entering the bay to attack friendly ships or cities along the shore.
Another part was to prevent an enemy from seizing the bay to use it for
a base of operations. Periodically, those charged with meeting this challenge
have had to answer three broad questions. The first was whether to fortify
the bay in addition to, or in place of, defending it by strictly naval
means. If the answer was yes, questions remained as to what type of fortifications
should be built and where they should be located. A look at how these
questions were answered in the past provides not only an insight into
an important aspect of Newport's history, but a review of the development
of American seacoast defenses as well.
The
Colonial Period
During the
colonial period, coastal defenses were largely a matter of local concern.
From the earliest period, the settlers of Newport appreciated the need
to defend their harbor against a changing array of potential enemies.
Although they agreed on the need for defenses, these early residents were
not always ready to devote the funds required to satisfy that need. When
Newport purchased Goat Island in 1673, for example, both ends of the island
were laid out for building lots, but the center was reserved for fortifications.
No work was undertaken until about 1700, however, when the first earthen
fortifications were constructed. The works of this period, both earth
and masonry, were bastioned fortifications similar in style to those of
Europe, but much less grand in execution. When gunpowder and the cannon
destroyed the military effectiveness of the high masonry walls of medieval
castles and fortified cities, European engineers began to search for a
satisfactory defense against these impressive new weapons. By the mid-1500s,
the Italians had discovered the answer: low earthen ramparts, faced with
masonry, surrounded by a ditch, and protected at the angles by bastions.
Bastions were arrow-shaped projections from the fortification's main wall
or curtain. These projections served the same role as the towers along
a medieval castle's wall: deny attackers any dead space along the walls
where they would be safe from the defender's weapons.
Although
the bastioned style of fortifications was developed over several centuries
by engineers of many countries, the style is known commonly as "Vaubanian"
after its most famous proponent, Sebastien le Prestre de Vauban. Starting
as a cadet in 1651, Vauban rose to the rank of marshal of France and became
famous as the engineer who fortified that country's borders during the
reign of Louis XIV. Although Vauban constructed or rebuilt more than one
hundred fortifications and supervised fifty-three successful sieges, his
writings and efforts to create a professional corps of engineers had an
even greater impact on military engineering than the works themselves.
In Vauban's time, military engineers were essentially civilian contractors
who worked with the army. Vauban's efforts led to the recognition of engineering
as a true military specialty and eventually to the establishment of schools
for the education of engineers. Vauban's writings and the works of others
about his style of fortifications became textbooks for the world's armies.
Having agreed
upon the need to protect their harbor, Newporters, with some familiarity
of the Vaubanian style of fortification in Europe, faced the question
of where to build the forts. The answer was determined by a combination
of geography and the characteristics of available ordnance. Narragansett
Bay has three openings to the ocean, known today as the West and East
Passages and the Sakonnet River. In earlier times these passages were
known respectively as the West, Middle, and East Passages. To avoid confusion,
current terminology is used throughout this article. Early surveys of
the bay indicated that the West Passage and the Sakonnet River were not
deep enough to accommodate major warships. Although this view later was
proved wrong, it formed the basis for most of the early plans to defend
Newport. In May 1702, the Rhode Island Assembly directed that a new fortification
large enough to mount twelve cannon be built to protect Newport Harbor
during the War of Spanish Succession (1702-1713). Goat Island was chosen
as the site of the new fort, which was named for Queen Anne who had succeeded
to the throne in March 1702. The cannon at Fort Anne would have been smoothbore,
muzzleloading guns. These cannon were probably 12- or 18-pounders, firing
solid iron balls of those weights, and mounted on either naval or field
artillery carriages. With effective ranges limited to hundreds of yards,
these weapons could have protected only Newport's inner harbor. Enemy
ships could still have entered Narragansett Bay and sailed it with impunity.
During the
colonial period, the fortunes of the works on Goat Island rose and fell
with the perceptions of threats from Britain's foreign enemies. After
the Treaty of Utrecht in 1714, for example, the garrison was disbanded.
Though renamed in 1730 for King George II, the work fell into disrepair.
Upon declaration of war between Britain and Spain in 1739, the Rhode Island
Assembly ordered Fort George repaired and fully armed. Newport's sea captain
and gentleman architect, Peter Harrison, was asked to design the new fort.
Drawing on his personal library, which contained several works on fortification,
including one by Vauban, Harrison produced a masonry work reported to
have mounted twenty-five guns in its lower battery and twelve on platforms.
Although the entrances to Narragansett Bay remained unprotected, the Assembly
did order the construction of watch towers on Conanicut Island and at
Point Judith, Castle Hill, Sachuest Point, and Brenton's Point. At the
time, the name Brenton's Point referred to the neck of land at the southwest
entrance to Newport harbor where Fort Adams now stands. The name-taken
from William Brenton, an early owner of the land-is now applied to the
southernmost tip of Aquidneck Island. Because current maps and charts
assign no name to the place where Fort Adams stands, the terms "old Brenton's
Point" and "new Brenton's Point" will be used to differentiate between
them.
The
Revolutionary War
In December
1774, shortly before the start of the American Revolution, another cycle
of disarming and rearming Newport's fortifications began, a cycle that
has characterized American coast defense policy throughout its history.
Sensing the gathering war clouds, and fearing the British would seize
the cannon at Fort George, the Rhode Island Assembly ordered that the
guns and ammunition be removed and taken to Providence. Appreciating the
vulnerability of the colonies, the Continental Congress urged them to
fortify their ports. The Rhode Island Assembly endorsed this concept on
June 28, 1775. Almost a year later, the citizens of Newport voted at a
town meeting to construct a fort at old Brenton's Point. Inhabitants were
ordered to help with the labor or pay a fine of three shillings for each
day they missed. By the end of 1776, the earthwork had been completed.
A battery of eight 18-pounder guns had been established on Conanicut Island
across from old Brenton's Point, and a small earthwork had been built
on Castle Hill. In addition, Fort George on Goat Island had been rearmed
with twenty-five guns, manned with a garrison of fifty-five, and renamed
Fort Liberty, and the battery on North Point had been enlarged and armed
with twenty cannon captured by Commodore Esek Hopkins from the British
at Nassau in the Bahamas. Additional fortifications existed at Bristol
and Howland Ferries to prevent Newport from being taken from the rear.
Unfortunately, the Americans failed to defend the West Passage. On December
7, 1776, Commodore Sir Peter Parker sailed a British fleet of seven ships
of the line, four frigates, and seventy transports carrying six thousand
troops unopposed up the West Passage and around the northern end of Conanicut
Island. The following day, the troops under Major General Henry Clinton
landed near Coddington Cove and marched on Newport.
After occupying
Newport, the British maintained most of the coastal batteries that they
inherited from the Americans and added a battery on Rose Island. The Revolutionary
War fortifications around Narragansett Bay-the only ones in the area that
have seen action against an enemy-were earthworks that carried their guns
en barbette meaning that they were mounted in the open on top of the ramparts,
firing over an earthen parapet. This style of fortification continued
to reflect French influence. Lacking trained military engineers at home,
the Americans had appealed early in the war to France for help. Louis
Lebeque Duportail, a Frenchman, rose to the command of continental engineers
under George Washington. His countryman, General François Lellorquis de
Malmedy, had been appointed "Chief Engineer and Director of the works
of defense" of Rhode Island in December of 1776.
To protect
the West Passage and correct the weakness they had taken advantage of,
the British constructed a rectangular redoubt at Beaverhead on Conanicut
Island. In addition, the British took a step that has not been repeated
since the Revolution: they constructed a line of fortifications to protect
Newport from an attack from the landward side. This line consisted of
trenches and earthen redoubts running from the high ground overlooking
Easton's Pond to Tonomy Hill and then north to Coddington Cove. An abatis-a
barrier of trees felled with the branches toward the enemy-was constructed
to serve the role of modern barbed wire, and Easton's Pond was deepened
by damming the inlet. To screen this defensive line to the north, the
British constructed a number of detached earthworks elsewhere on Aquidneck
Island, including Common Fence Point, Butt's Hill, and Fogland Ferry near
the area now known as the Glen. Hard work and planning on the part of
the British was to pay off handsomely in 1778, when the French and Americans
attempted to recapture Newport.
On July
29, 1778, a French fleet under Admiral Charles Hector Théodat, Count d'Estaing,
arrived off the entrance to Narragansett Bay, setting the stage for a
combined French-American att-r--on Newport. On August 4 and 5, two of
d'Estaing's ships ran the West Passage and rounded the northern end of
Conanicut Island. In response, the British burned a number of their ships
that were anchored off Newport to prevent their capture by the French.
On August 8, the main body of the French fleet, led by d'Estaing's flagship,
Languedoc, ran the East Passage under fire from British batteries and
anchored off Conanicut Island. Having already evacuated Conanicut Island,
Major General Sir Robert Pigot, the British commander, began to withdraw
his forces from the northern part of Aquidneck Island back to the lines
around Newport in anticipation of a siege. To hinder the movement of the
French fleet, the British scuttled their remaining ships, including a
large transport that was run aground between North Point and Goat Island.
Admiral d'Estaing
and Major General John Sullivan, commander of the American forces assigned
to capture Newport, agreed on a plan that envisioned an American crossing
of the Sakonnet River and a simultaneous landing of French troops by d'Estaing's
fleet on the west side of Aquidneck Island. On August 9, the situation
changed drastically. General Sullivan had moved his army across the Sakonnet
River from Tiverton to take advantage of the British withdrawal, but Admiral
d'Estaing had a very different set of concerns. That same day a British
fleet under Admiral Lord Richard Howe had arrived off the entrance to
Narragansett Bay. If Admiral Howe had landed troops on Conanicut Island,
Admiral d'Estaing would have been caught in a crossfire from those forces
and the batteries at Newport. Fearing that contingency and the possibility
of a sea fight in the restricted waters of the bay, d'Estaing took advantage
of a north wind on August 10 to run once again the British batteries guarding
the East Passage, this time headed out. The two fleets were still maneuvering
for position on the 11th when a violent gale struck. The damage that resulted
from the storm and battles between individual ships ultimately caused
both sides to retire.
Meanwhile
ashore, General Sullivan's army waited out the storm that destroyed much
of their supplies. When the weather cleared, they marched south, arriving
opposite the British lines on the afternoon of August 15. The Americans
began to construct siege batteries and actually opened the siege on August
19 with a cannonade of the British positions. Unable to breach the enemy
lines, plagued with internal problems, and aware that British reinforcements
under General Sir Henry Clinton were on the way, the Americans withdrew
to the north on the night of August 28. After fighting a running battle
with their pursuers, the Americans escaped from the island on August 31,
thereby ending the campaign to seize Newport. The British victory was
short-lived, however. In October 1779, they evacuated Newport voluntarily,
allowing the French to occupy the city in the summer of the following
year. Before leaving, the British "dismantled" most of the works protecting
Newport from the landward side.
In addition
to occupying the coastal defense works left by the British, the French
constructed a large work on Rose Island and a battery on Hallidon Hill
overlooking the works on old Brenton's Point. They named this latter work
Fort Chastellux in honor of one of Rochambeau's Maréschaux de Camp, the
Chevalier de Chastellux. The French also reworked the landward defenses
of Newport, an action that has obscured the origins of some of the remains
of those early fortifications.
Early
United States Coast Defense Systems
Following
the Revolutionary War, the former colonies once again let their seacoast
defenses fall into a state of disrepair. In October 1784, the Rhode Island
Assembly ordered that the works on Goat Island be repaired and armed.
The renovated fort underwent yet another change of name, this time to
Fort Washington. Concerned by the outbreak of war in Europe in 1793, the
United States Congress took action the following year to create a unit
of artillerymen and engineers, appoint a committee to study coast defense
needs, and appropriate money to construct a number of fortifications that
would become known as the First System. Newport was one of twenty-one
locations selected to be fortified. Lacking trained engineers to supervise
the work, Secretary of War Henry Knox placed a number of European engineers
under contract. On March 29, 1794, Major Etienne Nicholas Marie Bechat,
Sieur de Rochefontaine, was named the engineer for New England. Rochefontaine
designed three fortifications for Narragansett Bay, a work on Goat Island
to replace Fort Washington, another on Tonomy Hill, and a battery at Howland's
Ferry. As late as 1945, a stone with the name Rochefontaine carved into
it could be seen in the embankment in front of the Torpedo Factory's Explosive
Division. Having Anglicized his name to Stephen Rochefontaine, he became
commandant of the new Corps of Artillerists and Engineers in 1795, and
was replaced at Newport by another French officer, Major Louis Tousard.
Tousard was
no stranger to Newport, having fought there during the 1778 siege and
lost an arm during the fighting at Butt's Hill. He returned to France,
became involved in a revolution at Santo Domingo for which he was imprisoned,
was freed at the intercession of the American minister in Paris, and then
came to the United States where he was commissioned in the United States
Army. Between 1798 and 1800, Tousard supervised construction of several
works around Narragansett Bay, including an elliptical battery of stone
for twelve or thirteen guns at North Point, subsequently named Fort Greene
in honor of Revolutionary War General Nathanael Greene from Rhode Island,
and a rectangular fort with two circular towers on the western corners
located on Rose Island. Named Fort Hamilton after Alexander Hamilton,
this latter work was never completed. Tousard also supervised improvements
at Fort Washington, which was enlarged and once again renamed. Because
the name Fort Washington had been used for a new fort in Maryland, the
work on Goat Island was named Fort Wolcott to honor the Revolutionary
War service of Governor Oliver Wolcott, who had died on December 1, 1797.
Tousard also
designed an elliptical stone tower on a rocky point on Conanicut Island
across the East Passage from old Brenton's Point and near the offshore
rocks known as the Dumplings. This work was advanced for the time, designed
to have its guns mounted on platforms over casemates, arched stone and
brick chambers that served as a magazine and shelters for the garrison.
One authority on early American fortifications considers this work to
be the first American martello tower, a particular type of circular fort
with roof-mounted guns that became popular in Britain during the Napoleonic
wars. The work, which was never completed, was a frequent subject for
local artists in the nineteenth century. Never named officially, it has
been called Fort Louis, Fort Brown, and the fort at the Dumplings.
Another Tousard
project during these years was an irregular open work at old Brenton's
Point sited so that about twenty guns could cover the East Passage and
an equal number fire in the direction of Newport. An elaborate ceremony
was held on the Fourth of July in 1799 to open this new fort and to christen
it Fort Adams in honor of President John Adams. Major Tousard addressed
the assembled crowd. Over the arch of the gateway was a stone tablet with
the inscription:
Fort
Adams
The Rock on Which the Storm Will Beat
The storm
was coming in the form of the War of 1812, but it never beat against Fort
Adams. The Royal Navy blockaded the coast of New England during the war,
but never attempted to force an entry into Narragansett Bay. This omission
was undoubtedly fortunate for Newport. Although the East Passage was covered
by fortifications, the works had been declared inadequate by the secretary
of war. The other two passages into the bay were essentially open to an
enemy fleet. Except for an old battery at Bonnet Point that may have been
manned at some time, the West Passage remained unprotected, a fact noted
by British naval officers at the time. The Sakonnet River was also unprotected,
but the channel was less suitable for large ships, and a stone bridge
had been built across the river at Tiverton in 1810. The British failed
to take advantage of these weaknesses, however, and the defenses of Narragansett
Bay waited out the war without being tested.
During this
same general period, two other events took place away from Rhode Island
that were eventually to have an impact on the defenses of Newport. In
1802, the Congress separated the artillerists and engineers into two separate
corps and directed the latter to create a military academy at West Point,
New York. One of the driving forces for establishing the new academy was
the need to divorce the United States from its reliance on foreign engineers.
The second event was the publication by a French engineer of a multi-volume
work titled Fortification Perpendiculaire. Although Marc René, Marquis
de Montalembert published his work in Paris between 1776 and 1778, thirty
years were required for its influence to be felt in the United States.
Montalembert
proposed a new system of fortifications to overcome the weaknesses of
the works designed by Vauban and his successors. One weakness of the earlier
works was that the crews of guns mounted en barbette were exposed to enemy
fire, which included solid shot fired to ricochet down a line of guns,
and shell, a hollow projectile filled with explosive that shattered into
fragments when detonated by a fuse. In 1794, Lieutenant Henry Shrapnel
increased the danger to exposed gun crews with his invention of a projectile
called spherical case. Later named for Shrapnel, this new shell exploded
in the air raining musket balls on an enemy below. Montalembert's system
protected a fort's gunners by placing most of them in covered casemates
with openings called embrasures for the guns. By stacking rows of casemates
on top of one another, the new system also allowed more guns to be mounted
along any given length of a fort's perimeter. This feature was particularly
important for seacoast fortifications, which had only a limited time in
which to fire at a passing enemy fleet. Not all engineers agreed with
this new concept. In 1809, Louis Tousard published an early American textbook
on artillery and fortifications titled The American Artillerist's Companion.
After discussing a variety of systems of fortification, including Montalembert's,
Tousard concluded, "The defects that are manifest in all these different
systems show the superiority which exists, to this day, in all the fortifications
which have been constructed by Vauban."
Frightened
by the possibility of war with Great Britain, President Thomas Jefferson
began a fortification program in 1807-1808 that has come to be known as
the Second System. This system was distinguished from the First System
by the use of Montalembert's concepts and the replacement of foreign engineers
by American ones, many of them recent graduates of the new United States
Military Academy. The Second System brought no new works to Narragansett
Bay, but Newport did not have to wait long to feel the impact of Montalembert
and the new American engineers.
Joseph
G. Totten and the Third System
Newport may
have escaped the wrath of the British during the War of 1812, but the
nation's capital was not so lucky. Determined to prevent a future repetition
of the burning of Washington, President James Monroe mentioned the need
for better coastal defenses in his inaugural address of March 4, 1817.
A year earlier, the army had created a board to study the subject and
recommend what fortifications were required. Membership included Brigadier
General Joseph G. Swift, chief of engineers, and two other American engineers,
Lieutenant Colonels William McRee and Joseph G. Totten. Apparently lacking
full confidence in American officers to accomplish such an important task,
the president had appealed to France for a distinguished engineer to head
the board. In response, the French sent Simon Bernard, a graduate of the
École Polytechnique who had fought with distinction in the Napoleonic
wars. In recognition of his position, Bernard received rank and pay equal
to that of General Swift. Swift and McRee both considered Bernard's appointment
to be an insult to American engineers and resigned from the board shortly
thereafter. Except for a short absence for another assignment, Totten
stayed to assist Bernard in planning what became known as the Third System
of fortifications. After Bernard returned to France in 1831, Totten became
America's undisputed expert on fortifications.
When Bernard's
board made its report in 1821, it recommended an extensive building program
to cover the nation's seacoasts with modern masonry fortifications. The
plan for Narragansett Bay included fortifications at old Brenton's Point,
the Dumplings, and Rose Island, designed to protect the East Passage.
The plan also envisaged that Newport's inner harbor would continue to
be protected by Forts Greene and Wolcott. The Sakonnet River was closed
by the stone bridge at Tiverton and the troublesome West Passage would
be blocked by an underwater dike below Dutch Island designed to permit
the passage of small vessels but not large warships. Work on the Dumplings,
Rose Island, and the underwater dike was never undertaken, but construction
started at old Brenton's Point in 1824 with an appropriation from Congress
of fifty thousand dollars. The first order of business for Lieutenant
Andrew Talcott, the senior engineer, was to prepare the site for the new
construction. Louis Tousard's earlier work had been declared "worse than
useless" and was completely leveled. The name Fort Adams was retained
for the new fort, however.
On August
10, 1825, Lieutenant Colonel Totten arrived at Fort Adams to take charge
of the work. Having helped Simon Bernard plan the entire Third System,
Joseph Totten was now to supervise construction of one of its true masterpieces.
He was to remain in Newport until December 7, 1838, when he left to become
chief of engineers of the United States Army. Artillery of the day dictated
a site close to sea level to eliminate any dead space under the fort's
guns. Old Brenton's Point met that criterion, but space limitations precluded
a work in the shape of the regular polygons prescribed by theory. Totten
chose instead an irregular pentagon with the northeast bastion particularly
squeezed to accommodate the nature of the site. Along the two fronts facing
the bay, Totten chose one- or two-level casemates in the style of Montalembert.
To protect the rear of the fort from attack from the land, Totten designed
a complex set of Vaubanian defenses. The heavy, earth-filled ramparts
of that style of fortifications were considered more resistant to the
battering of enemy siege artillery than multilevel casemates. To prevent
a besieger from commanding the fort from the high ground farther down
Brenton's Neck, Totten constructed a powerful redoubt-a miniature Fort
Adams in some respects-near the present Eisenhower House.
Fort Adams
is a massive work with structural walls constructed of local shale and
Maine granite. Alexander McGregor, a Scots mason and Newport resident,
oversaw the stonework, which is still relatively intact. McGregor also
supervised construction of several other notable buildings in Newport,
including the Perry Mill, the Newport Artillery Company armory, Stone
Villa, and Swanhurst. Willard Robinson notes in his detailed work on the
fort that bricks for the vaulted casemates came from local kilns. At the
time he was building the fort, Colonel Totten frequently advertised in
the Newport Mercury for New England contractors to provide millions of
common bricks. Within the Third System, only Fort Monroe at Newport News,
Virginia, and Fort Jefferson on the Dry Tortugas off Key West, Florida,
are larger. Neither displays the sophisticated engineering features that
make Fort Adams a showcase for the art of fortification. Features of Fort
Adams that are uncommon or unique in United States military architecture
include galleries under the ditches, counterscarp galleries, underground
listening galleries tunneled under the glacis, and extensive outer defenses
including the redoubt and tenailles, massive earth-filled, masonry cribs
designed to protect the outer face of the fort's crown work from battering
by a besieger's artillery.
Most of this
innovation can be attributed to Totten's inventive mind, and his use of
the construction, which lasted until 1857, as a school of application
for young engineer officers. During this time, Totten conducted scientific
experiments to determine the resistance of various materials used in fortifications
to enemy fire, designed a greatly improved embrasure for seacoast forts,
and made numerous contributions to civil engineering. When he died in
1864, he was recognized as one of the country's greatest engineers. In
writing a eulogy of Totten for the Smithsonian Institution, John Barnard,
another senior military engineer, noted that Fort Adams had "called for
the application of most of the rules of the art and many of those special
arrangements which form the themes or treatises upon 'fortification.'"
Barnard further stated, "In these respects, [Fort Adams] has no parallel
with us."
During the
long period of Fort Adams's construction, artillery had also been improving.
Better gunpowder allowed greater range from smoothbore cannon. Although
solid shot, sometimes heated red hot in furnaces, had long been the standard
projectile for use against wooden ships, the firing of shell from guns
became increasingly common. Previously the use of shell had been limited
largely to short-barreled mortars and howitzers. Because shells were hollow
and could vary in weight, guns specifically designed to fire shells were
classified by the diameter of their bores rather than the weight of the
projectiles fired. In spite of this new development, Fort Adams was designed
for 468 conventional seacoast guns mounted both in casemates and en barbette
on the upper tier of the fort. No more than a fraction of that number,
however, was ever installed. Carronades-short-barreled naval guns firing
canister or grape shot-were mounted in the bastions to keep attackers
away from faces of the fort. The seacoast guns were still muzzleloaders
and were still laid to fire across the East Passage. Ships that might
attempt to run the fire of the fort's guns were similarly armed, although
often with guns of a smaller caliber. Fort Adams's granite walls were
generally invulnerable to fire from smoothbore ship's guns of the period.
Unfortunately, that situation was to change about the time Colonel Totten's
masterpiece was completed.
The
Civil War and its Aftermath
The two decades
before the outbreak of the Civil War saw major improvements in artillery.
Individuals such as Captain Thomas Jefferson Rodman of the United States
Army and Lieutenant John A. Dahlgren of the United States Navy conducted
experiments that led to the scientific design of artillery pieces. The
result of this work was ordnance with more power and greater range. Others
worked on rifled artillery. Unlike smoothbore guns, rifled ones had spiral
grooves in the bore that imparted a spin to the projectile. The spin stabilized
the projectile in flight giving greater accuracy and range. Rifling also
permitted the use of elongated, pointed projectiles in place of spherical
cannon balls. Experts disagreed at the time about the impact these improvements
would have on fortifications. Some said the new weapons presented no greater
threat than the ones they replaced. Experience during the Civil War proved
that point of view wrong.
Third System
forts were destined to play an important role at the start of the war.
The Confederate bombardment of Fort Sumter in Charleston harbor on April
12, 1861, marked the outbreak of fighting. In April of the next year,
Union forces under General Quincy A. Gillmore took Fort Pulaski near Savannah,
Georgia, under siege. Fort Pulaski was located on an island at the mouth
of the Savannah River, and no less an engineer than Robert E. Lee had
earlier pronounced it to be impervious to any artillery that could be
placed within effective range. Lee based his estimate on the capability
of smoothbore artillery. Unfortunately for the garrison of the fort, the
Union troops were using rifled guns in addition to smoothbore siege artillery.
In less than two days, Gilmore's artillery had dismounted eleven of the
Confederate guns and battered a large breach in the fort's brick wall.
Fort Pulaski surrendered on April 11, 1862, a date that also could be
said to mark the obsolescence of the masonry forts of the Third System.
Given the focus of the fighting in the south and west, improving the defenses
of Narragansett Bay was not a high priority for the Union. Fort Adams
was rearmed, however, with new Rodman guns, 10-inch pieces in the casemates
and 15-inch guns in open batteries atop the southwest bastion of the crown
work. To protect the West Passage, units from the 14th Rhode Island Heavy
Artillery, a black regiment, were stationed on Dutch Island from September
until December of 1863. These soldiers manned eight artillery pieces emplaced
in an earthen battery they had constructed. Later, the army constructed
permanent batteries for 10- and 15-inch Rodman guns on the island.
Following
the war, engineers argued about the best alternative to masonry fortifications.
The Europeans were experimenting with armored casemates and turrets, but
American engineers decided the cheapest and most effective plan was to
revert to open earthworks of an earlier age. During the war, such works
had proven extremely resistant to artillery and United States forces had
become experienced in their construction. This shift also reflected the
influence of Dennis Hart Mahan, who taught engineering at West Point from
1832 to 1871. In 1846, Professor Mahan, father of Naval War College strategist
Alfred Thayer Mahan, had written a textbook on earthen fortifications
for use by cadets at the Military Academy.
Inexpensive
earthen forts matched not only engineering thinking of the time, but also
the fiscal mood of Congress. In 1876, the Democrats took control of the
House of Representatives for the first time since 1859. In spite of the
deteriorated condition of the country's defenses, Congress promptly cut
the Army's requested budget for fortifications from $3,500,000 to $315,000.
Only $100,000 of that was allocated to repair fortifications. The remainder
was to be used for experiments with mines and other ordnance.
Naval mines
became a weapon to be reckoned with during the Civil War. At that time,
they were called torpedoes, a term that has since been applied to self-propelled
underwater missiles. David Bushnell had used them against the British
during the Revolutionary War, and Robert Fulton had successfully demonstrated
their power in the early 1800s. In 1842, Samuel Colt, better known for
his revolvers, demonstrated the effectiveness of electrically fired mines
for President John Tyler and other officials by sinking a schooner in
the Potomac River. Congress appropriated $15,000 for Colt to continue
experimenting, but many experts were not impressed. General Totten, now
chief of engineers, disparaged the mine as an old idea that had not demonstrated
its effectiveness in war. The Confederates proved General Totten wrong
by sinking twenty-nine Union vessels with mines and damaging fourteen
others during the Civil War. In the face of such evidence, the dissenters
gave in. In 1869, the United States Navy established the Torpedo Station
on Goat Island at Newport. In the 1870s, the Army's engineer battalion
at Willetts Point, New York, was given the mission of developing a mine
system for harbor defense. Ironically, the fort located at Willetts Point
was named for General Totten, who had died in 1864.
With the
exception of these new developments, American coast defenses continued
to languish. In 1884, Congressman Roswell Horr compared United States
forts attempting to defeat a modern warship to trying "to stop a mad rhinoceros
by firing green peas out of an old-fashioned popgun." In November 1887,
a squadron of United States Navy ships under the command of Rear Admiral
Stephen B. Luce conducted maneuvers at Newport. During the exercise, a
squadron of five ships ran the East Passage to land marines against a
force defending Coddington Cove. More than twenty years after the end
of the Civil War, Fort Adams could reply with nothing more powerful than
two 15-inch Rodman guns en barbette and ten 10-inch Rodmans in the casemates.
Umpires did rule, however, that two ships would have been sunk by mines
during the passage.
The
Endicott Board and the Early Twentieth Century
The period
following the Civil War saw revolutionary improvements in artillery, particularly
in Europe. Smoothbore, muzzleloading guns of iron that used black powder
were replaced by rifled, breechloading guns made of steel and firing smokeless
powder. Annual reports of the United States chief of engineers in the
early 1880s reflect the opinion that these new weapons had made American
coast defenses, once the strongest in the world, obsolete. A West Point
professor writing at the time noted that the forts had become, "not only
weak, but absolutely more dangerous to the defenders than to the enemy."
A hit from a modern ship's gun would have turned Fort Adam's granite walls
into splinters as deadly as shrapnel.
Recognizing
this weakness, Congress added a provision to its 1885 Fortifications Appropriation
Act requiring the president to appoint a special board similar to the
earlier Bernard Board to study the issue of coast defense. In May of that
year, President Grover Cleveland appointed a board headed by his secretary
of war, William Crowninshield Endicott. The board, which included civilians
as well as military and naval officers, became known as the Endicott Board.
The board issued a comprehensive report in January 1886 that recommended
a coast defense system consisting of modern ordnance mounted in up-to-date
concrete fortifications. Implementing the board's report represented an
incredible challenge. At the time, for example, the United States had
no ordnance facility capable of manufacturing such modern steel artillery
pieces. The cost of implementing the board's recommendations was estimated
at $126,377,800, a figure that shocked Congress. Rather than implement
parts of the report's recommendations, Congress failed to enact a fortifications
appropriation at all for the next two years. Once started, work proceeded
slowly, but was given an impetus by the outbreak of the Spanish-American
War and scares of bombardments by the Spanish fleet along the eastern
seaboard.
Construction
of the new system required the cooperation of several branches of the
Army, the engineers who designed and built the fortifications, the ordnance
experts who designed the guns and supervised their emplacement, and the
artillerymen who manned the guns. The artillery had not yet split into
field artillery and coast artillery. The engineers were forced to balance
cost against protection in designing the new forts. As a result, they
once again rejected armored casemates and turrets-which afforded gun crews
great protection-in favor of open emplacements of concrete banked on the
sides facing the enemy with thick layers of earth and sand. This type
of fortification offered reasonable protection from direct fire that would
be expected from an enemy ship. Such emplacements had the added advantage
of being very difficult to spot from the sea. Added protection was expected
from the manner in which the new guns were to be mounted.
Armament
for the new coast defense system can be grouped into four classes. First,
large caliber guns would perform the traditional role of attacking enemy
warships. Designers of the gun batteries were confronted with the problem
of protecting the gun crews from enemy fire. Having rejected armored casemates
and turrets because of cost, engineers found a compromise solution in
the form of a gun mount known as the disappearing carriage. The disappearing
carriage was a complex mechanism that allowed a gun's barrel to project
over a high concrete parapet for firing. When fired, the gun's recoil
caused it to descend below the parapet where the crew could load the next
round. In the loading position, the crew was protected from direct fire
by the concrete parapet and as much as forty feet of sand and earth in
front of it. While providing relatively cheap protection, disappearing
carriages had several important weaknesses. Obviously they offered no
overhead protection. Additionally, technical considerations limited both
the traverse and the range of guns mounted on this type of carriage. To
overcome this disadvantage, some guns continued to be mounted on barbette
mounts. Second, were seacoast mortars. Instead of firing directly at an
enemy ship as would a gun, a mortar lofted a large caliber shell toward
an enemy ship along a high trajectory. Rather than hitting a ship on the
side, where the armor was thickest, a mortar shell would pierce the ship's
relatively weak deck and explode deep within the vessel. The mortars'
high trajectory also allowed them to be emplaced well back from the shore
line where they were relatively protected from the flat trajectory fire
from ships' guns. Because the target could not be seen by the gunners,
however, mortars required a sophisticated system of observation and fire
control. Third, were electrically-fired mines, which had assumed an increasingly
important role in coast defense. Finally, small-caliber, rapid-fire guns
were developed to deal with a new threat, the swift torpedo boat that
could sneak into an anchorage and wreak havoc. These guns could also cover
minefields to prevent an enemy from sweeping them.
The Endicott
Board recommended twenty-seven ports be protected under the new system.
New York and Boston were first and third in order of priority. Narragansett
Bay was number eleven. Because of this relatively low priority, construction
was barely underway around Newport when the Spanish-American War broke
out in April 1898. Had the Spanish Fleet attempted to enter Narragansett
Bay, it mainly would have faced United States guns from the Civil War
period augmented by a few modern weapons in temporary batteries. The Spanish
would have had to contend with the minefield blocking the East Passage,
however, as did Joshua Slocum when he returned to Narragansett Bay in
June 1898 from his historic, single-handed cruise around the world. When
construction of the new forts began in Narragansett Bay shortly before
the turn of the century, changes in ordnance required the engineers to
rethink the locations of the forts. The increased range of guns presented
the main challenge. A 12-inch gun could fire eight miles, for example.
Instead of firing across the entrances to the bay in the manner of earlier
muzzleloaders, the new guns required a location that would allow them
to be fired out to sea along the line of a column of ships attempting
to sail into the bay. The high ground at Fort Adams adjacent to the Third
System redoubt provided room for four gun batteries, including Battery
Reilly with two 10-inch disappearing guns. Two batteries of 12-inch mortars
were also located at Fort Adams. Across the East Passage from Fort Adams,
Louis Tousard's old fort on the Dumplings was finally demolished to make
room for several batteries of a new work called Fort Wetherill.
Fort Wetherill
had some of Narragansett Bay's biggest guns of the period, including two
batteries of 12-inch disappearing guns. The wharf built below where Tousard's
fort once stood became the base for the mine defenses of the East Passage.
Across Conanicut Island at Beaverhead, a new position was constructed
to protect the West Passage. Named Fort Getty, this new work contained
three gun batteries, including one with three 12-inch disappearing guns
that was named for Louis Tousard. Two other works were also placed to
guard the West Passage. Dutch Island was transformed into a full-fledged
fortified position named Fort Greble. The fort's armament included three
gun batteries and a battery of mortars to complement those at Fort Adams.
Construction of Fort Kearny, the last of Narragansett Bay's Endicott works,
began in 1906 near the South Ferry landing at Saunderstown. Containing
three batteries of 3- and 6-inch guns, this fort protected the mainland
shore of the West Passage. The Sakonnet River continued to be a weakness
in the defenses of Narragansett Bay. Although the depth of the channel
prevented major warships from gaining access to the bay by this route,
coast defense commanders worried that smaller enemy vessels might take
advantage of this "side door." During joint Army-Navy maneuvers in 1902,
the commander of Fort Adams periodically trained his searchlights up the
bay in hopes of detecting any enemy ships that might have sneaked in through
the Sakonnet River. During World War I, the army moved two 4.72-inch guns
from Fort Adams and emplaced them temporarily at Sachuest Point to protect
the mouth of the Sakonnet River.
World War
I saw no enemy fleets attempting to force Narragansett Bay or shell the
cities along its coast. The war did see technical developments that were
to force a reconsideration of United States coast defenses, however. On
one hand, ordnance designers made great strides in increasing the range
and power of artillery pieces. Technical considerations involving the
construction of naval turrets of the period meant that for a given size
of gun, a coast defense weapon would have a greater range than its shipboard
equivalent. The United States Army's 16-inch coast defense gun, Model
1919, had a range of 49,1d>
ards. In comparison, the 16-inch guns of
the battleship Maryland, which was laid down in 1917, had a range of 35,000
yards. Army engineers decided to rely on this sizable differential to
protect long-range coast defense batteries in lieu of costly concrete
cover for them. Long-range 12- and 16-inch guns were once again mounted
on barbette carriages which allowed 360-degree traverse and drastically
reduced construction costs. Unlike many other important harbors, Narragansett
Bay did not receive any of these new weapons. Unfortunately, another World
War I development, the bomber aircraft, was to force engineers and artillerymen
to reconsider this latest approach to coast defense. World War II and
the End of Coast Defense Airplanes were to affect coast defenses in several
important ways. In the view of some Army officers, the airplane was the
ideal instrument to continue the trend of increasing the range of coast
artillery. Instead of extending ranges hundreds of yards with a new cannon,
they argued, extend ranges hundreds of miles with a new bomber. A variety
of circumstances combined to encourage the proponents of aerial coast
defense. Disciples of air power believed that strategic bombing alone
could win wars without the carnage that attended ground fighting of the
type that had occurred in Europe during World War I. The key to such bombing
was the development of a modern long-range bomber. This development, in
turn, rested on money from Congress.
Congress
was in no mood to provide money for a weapon that could be used only in
another overseas war. An improved way of defending the United States,
however, was a different matter. The eventual result of this effort was
the Boeing B-17. When this bomber became famous in World War II as the
Flying Fortress, most Americans assumed the name referred to the unprecedented
amount of defensive armament it carried. In fact, the name referred to
the plane's initial mission as a flying coast defense fort. In a series
of tests in 1921, Army bombers led by Major William "Billy" Mitchell sank
several former German and United States warships that had been adapted
for use as targets. Although Mitchell demonstrated that, under certain
conditions, aircraft could sink large ships, a question remained whether
aircraft could locate an enemy fleet at sea in the days before radar.
On May 12, 1938, Army Air Corps B-17s intercepted the Italian liner Rex
776 miles off the United States coast. In addition to demonstrating the
ability of land-based aircraft to locate ships far at sea, this action
renewed rivalry between the Navy and the Army over the responsibility
for such missions. Improvements in aircraft also caused problems for the
proponents of conventional coast defense methods.
The problems
involved the protection of coast defense forts from aerial attack by an
enemy. Part of the solution was to add antiaircraft guns to the types
of ordnance already in the coast artillery's arsenal. This effort required
not only new guns, but a new array of fire control equipment such as height
finders. The second part of the solution involved the redesign of gun
emplacements. Construction of the new long-range barbette gun positions
had hardly begun before they were obsolete. The answer to this new problem
was an old idea, the casemate. Paralleling the transition from Vauban
to Montalembert, coast artillery guns were once again mounted in covered
positions that protected them, but limited their fields of fire. This
time, however, the casemates were massive structures of reinforced concrete
covered with tons of earth instead of the elegant brick vaults of General
Totten's time. As so often had happened in the past, emphasis on America's
defenses declined following the end of World War I. Many of the guns were
removed from the forts around Narragansett Bay. In one sense the loss
of these guns made no difference. At the start of World War II in 1939,
a modern battleship could have shelled Newport while remaining at sea
beyond the reach of the area's longest range guns.
The outbreak
of fighting in Europe emphasized the weaknesses of America's defenses
and prompted measures to overcome the problems. For the first time since
the colonial period, entirely new locations had to be found for the modern
casemates. Rather than defending the three entrances to the bay separately,
the range of the new 16-inch guns permitted a single defense of all three.
In 1940 and 1941, the United States government acquired property at Sakonnet
Point and Point Judith to create Forts Church and Greene respectively.
The twenty-six-mile range of these huge guns allowed them to take an enemy
under fire long before his ships were close to entering Narragansett Bay.
To the east, the guns could reach out as far as Martha's Vineyard; to
the west, almost as far as the tip of Long Island. At Fort Church, a battery
of two 16-inch guns was complemented by a battery of two 8-inch guns,
also in casemates. A battery of two modern 6-inch guns in steel shields
was also located at Sakonnet point as were positions for 155mm mobile
artillery pieces. At Fort Greene, one battery of 16-inch guns in casemates
was completed. Another was started, but construction was suspended in
1943 when the direction of the war indicated that United States coastal
defenses would probably never see action. Point Judith also had a modern
6-inch battery and prepared positions for 155mm mobile artillery.
Exploiting
the full capabilities of these modern forts required the establishment
of a new fire control system using both radar and optical instruments.
Some of the resulting fire control structures were concrete towers and
silos whose looks betrayed their military nature. Others, however, were
disguised to look like beach front cottages. Locations ranged from Gay
Head on Martha's Vineyard to Block Island, with numerous other sites along
the Rhode Island coast. Concern for the security of Narragansett Bay increased
after the start of war in 1941 and a second line of defense was begun.
In 1942, the government purchased land at Beavertail on Conanicut Island
for the construction of Fort Burnside. A modern 6-inch battery was constructed
there, and the 3-inch guns from Fort Getty's Battery Whiting were moved
to Fort Burnside to cover the entrance to the East Passage. Opposite Beavertail
on the mainland, Fort Varnum was established with older 6-inch guns that
had been moved from Battery House at Fort Getty and 3-inch guns taken
from Fort Kearny. The smaller guns were later moved again, this time to
Fort Getty. At various times, 37mm and 90mm guns were mounted for anti-motor-torpedo-boat
duty at locations that included Fort Getty, Fort Varnum, Fort Wetherill,
and new Brenton's Point, where positions for 155mm mobile artillery pieces
were also located.
In addition
to the firepower of this wide array of guns, an intricate system of underwater
listening devices, minefields, and antisubmarine nets also protected Narragansett
Bay. Seaward from the mouths of the East and West Passages lay underwater
cables that could detect the magnetic field of a submarine or surface
ship passing over them. Closer to the shore were hydrophones that could
pick up the sound of a ship's propeller. Command posts ashore analyzed
information from these detection systems to determine the nature of any
contacts. Next came two lines of electrically controlled mines. Modern
mine casemates, bunkers from which the minefields were controlled, at
Hull Cove on Conanicut Island replaced earlier ones at Fort Adams, Fort
Wetherill, and Fort Greble. Completing the system were the giant steel
nets that closed the East Passage at Fort Wetherill. Made in two sections,
one end of each section was anchored to the shore. The other ends of the
two sections were held by net tending ships stationed in the channel where
they could open and close the barrier like a giant bi-fold closet door.
The West Passage was blocked by a solid anti-boat boom and net that could
not be opened. The ends were anchored at Fort Getty and Fort Kearny. As
World War II progressed, the threat of an enemy bombarding Narragansett
Bay declined steadily. Most of the guns remaining in Endicott period forts
were removed for scrap, and work was suspended on uncompleted modern casemates.
German submarines
continued to operate off the coast until the end of the war, but they
remained an enemy beyond the reach of traditional coastal defenses. Air
attack remained a very real threat, however, and antiaircraft batteries
sprang up aroe wethe bay. Many were entirely new installations, such as
the ones on Coaster's Harbor Island, on Eustis Avenue in Newport, and
on Ruggles Avenue and Old Fort Road near the site of the current Rogers
High School. Other batteries showed up in some familiar places. As early
as the 1920s, the army had emplaced antiaircraft guns at Fort Greble,
between the Endicott batteries at Fort Wetherill, and atop Joseph Totten's
redoubt at Fort Adams. During World War II, soldiers also manned naval
antiaircraft guns mounted on Rose Island around Louis Tousard's Fort Hamilton.
During the war, none of the many guns protecting Narragansett Bay saw
action. Had they been called upon to do so, Fort Adams, the masterpiece
of the bay's earlier defenses, would have been far to the rear of the
battle. General Totten might have been pleased to know, however, that
the battle would have been controlled from an underground command center
located not far from his Third System redoubt.
After the
war, coastal defenses languished for a while in a state of limbo. When
the threat shifted from enemy fleets to intercontinental ballistic missiles,
the forts were closed and put to other uses. Most are parks, like Fort
Adams, which is now part of a state park that includes athletic and sailing
facilities and is a favorite place for picnics and other recreations.
The fort itself has been the backdrop for musical events, including the
Jazz Festival, which began in Newport in 1954. Fort Varnum and parts of
Fort Greene at Point Judith are still used by the military. Fort Church
is home to a golf course, and Fort Kearny houses a research reactor for
the University of Rhode Island. They all stand as silent reminders of
the great system of fortifications that once defended the fleet that,
perhaps fittingly, is now also gone from the waters of Narragansett Bay.
