The Thread That Held a Revolution

As we approach the 250th anniversary of American independence, it's worth
pausing to consider a deceptively simple question: where did the rope come
from? Not the metaphorical rope of revolutionary rhetoric or the hangman's
noose that threatened traitors, but the actual miles upon miles of hemp cordage
that held together every sailing vessel, hoisted every sail, moored every ship,
and quite literally connected the scattered colonies into a functioning naval
power capable of challenging the British Empire.
The answer reveals one of the untold stories of American independence—how
a seemingly mundane industry, operating in long, narrow buildings that
stretched across the colonial landscape like threads themselves, became
strategically crucial to revolutionary success. When trade with England was cut
off and the Continental Congress found itself trying to supply armies and
navies with everything from muskets to medicinal supplies, American ropemakers
faced an extraordinary challenge: could they produce enough cordage to keep
American ships sailing and American forces supplied?
The Astonishing Appetite for Rope
To understand the magnitude of this challenge, consider a single ship:
the USS Constitution, that magnificent frigate launched in 1797 and
affectionately known as "Old Ironsides." A sailing frigate the size
of Constitution required approximately 40 miles of cordage of varying
diameters. Forty miles of rope—on just one vessel. More than 120,000 pounds of
hemp fiber was needed to rig the 44-gun USS Constitution, and that figure
doesn't even account for the additional hemp required for canvas sails and
caulking materials.
Yet the Constitution was only one ship among hundreds that formed the
Continental and later United States Navy, not to mention the countless
privateers and merchant vessels that also depended on American independence for
their operation. During the 1800s, sailing ships required miles and miles of
rope, and during the Revolutionary period, when every vessel was needed to
transport troops, supplies, and goods, the demand was virtually insatiable.
The stagger
ing scale becomes even clearer when we consider specific rope dimensions.
The biggest ropes on USS Constitution were 3 inches in circumference
(approximately 1 inch in diameter), while the anchor cables were 7 inches in
diameter and made by twisting smaller ropes together. These weren't delicate
threads but massive hawsers that could moor thousand-ton vessels in stormy
harbors or tow disabled ships to safety. Each required enormous quantities of
fiber, painstaking labor, and specialized facilities to manufacture.
The Ropewalk: Where Fiber Became
Freedom
The manufacture of rope took place in specialized factories called
ropewalks, often long, narrow buildings that had to be longer than the lengths
of rope made there, stretching hundreds or even thousands of feet in a straight
line. These remarkable structures were among the most distinctive industrial
buildings in colonial America, their extreme length-to-width ratios making them
instantly recognizable in any port town or manufacturing center.
The term "ropewalk" was literal in its origins. Early ropewalks
were generally outdoors and were quite literally walks, or paths, where workers
laid out and twisted rope. In the mid-1600s, ropemakers in the American
colonies created outdoor spaces on straight and level ground where workers
could walk backward for hundreds of feet while spinning and twisting fibers
into cordage.
A group of Bostonians solicited English ropemaker John Harrison to
establish a ropewalk in 1641 near where the South Station is today, marking the
beginning of American rope manufacturing. The industry spread rapidly
throughout the colonies as the crucial connection between hemp cultivation and
maritime trade became apparent. By the Revolutionary period, ropewalks had
evolved from open-air paths into substantial buildings, though their
fundamental operating principle remained unchanged: the length of the ropewalk
determined the longest rope that could be manufactured within it.
From Field to Fiber: The Hemp
Connection
The raw material for all this rope came from an unlikely source—a plant
that today carries controversial associations but which colonial Americans
viewed simply as an essential agricultural commodity. Hemp arrived in Colonial
America with the Puritans in the form of seed for planting and as fiber in the
lines, sails and caulking of the Mayflower. The plant, cannabis sativa, wasn't
cultivated for any psychoactive properties but rather for the extraordinarily
strong fibers contained in its stalks.
Hemp, from the genus cannabis, can grow up to 16 feet in height and has
been cultivated for nearly three millennia. The strong, durable fiber used to
make cordage is located in the stalk of the plant. Hemp was the fiber of choice
for maritime uses because of its natural decay resistance and its adaptability
to cultivation—crucial characteristics when ropes had to withstand constant
exposure to salt water, sun, and the tremendous mechanical stresses of
controlling sails and anchoring ships.
British colonial policy had long recognized hemp's strategic importance.
Britain's colonies were compelled by law to grow hemp. Ship captains were
ordered to disseminate hemp seed widely to provide fiber wherever repairs might
be needed in distant lands. Henry VIII (1491-1547) required farmers to plant
1/4 acre in hemp for every 36 acres under cultivation, establishing a pattern
of government-mandated cultivation that would continue for centuries. Oakum is made by picking apart old ropes. Oakum is used for caulking ships, sealing joints in pipes, closing spaces between masonry and wood framing, and packing horse hooves.

By the mid-1600s, hemp had become an important part of the economy in New
England, and south to Maryland and Virginia. The Colonies produced cordage,
cloth, canvas, sacks and paper from hemp during the years leading up to the
Revolutionary War. The first crops of hemp were grown in Salem, Massachusetts
in 1640 and taxes at the time could be paid with hemp, demonstrating the crop's
accepted status as a form of currency in colonial economies.
The Art and Science of Ropemaking
The transformation of hemp stalks into usable cordage required both
physical labor and technical sophistication. The process began in the fields,
where hemp plants were harvested, the woody outer stalks separated from the
valuable inner fibers through a laborious process called retting. These fibers,
each about three feet long, then had to be combed or hackled—essentially
brushed with metal combs until the fibers lay straight and parallel, ready for
spinning.
In the ropewalk a spinner with hackled hemp wrapped around his waist
twisted the fibers between thumb and fingers into a yarn that was spun into a
thread. It was then fed to a spinning wheel run by another person, usually a
child, as the spinner walked backward down the walk. This image—of workers
walking backward down quarter-mile-long buildings while spinning fibers into
thread—captures something essential about pre-industrial manufacturing: the
intimate connection between human movement, mechanical process, and finished
product.
The actual construction of rope involved multiple stages, each requiring
careful control and precise technique. Most rope is of three or four strands
and making it into rope is done by twisting one around the other. There are
three parts: fiber, thread and strand. The individual plant fibers are twisted
into thread, the threads are twisted into strands and the strands twisted into
rope.
A rope's strength comes from the multiple and opposite twisting of its
components: ropemakers twisted slivers clockwise to form yarns, then twisted
yarns counter-clockwise to form strands. Finally, three strands were twisted
together clockwise to form a typical rope. This twisting also prevented the
rope from unravelling. This alternating direction of twist—clockwise, then
counter-clockwise, then clockwise again—created internal tensions that held the
rope together while also making it resistant to unwinding under load.
The process required both strength and precision. Fibers were twisted
clockwise into yarns and then coiled onto bobbins. Workers brought these
bobbins of yarn to the first floor and placed them on an upright rack at one
end of the Ropewalk. Then, workers tied together yarns from multiple bobbins to
a twisting device on a moveable cart. As this cart moved on a track down the
length of the Ropewalk, it pulled the yarns from the bobbins and twisted the
yarns into a single strand.
The Hazards of Hemp: Fire and
Ropewalks
The ropewalk industry operated under constant threat of catastrophic
fire. Hemp fibers created clouds of dust that hung in the air of ropewalk
buildings, while the pine tar used to waterproof finished rope required heating
to liquid form. A great danger in ropemaking was fire because of the prevalence
of hemp fibers and dust and the hot tar used to waterproof the rope.
On July 30th, a fire began in Edward Howe's ropewalk consuming it and
five others, culminating in ninety-six buildings being lost altogether. The
fire caught in the Rope Walk of Mr. Howe, by an accident in heating some tar,
and before the Inhabitants could be alarmed and assembled, it had gained so
great a head as to render abortive all attempts to secure, from the flames, any of those elegant and
valuable Rope Walk. Hot North Carolina tar, flammable fibers and wooden
buildings were a volatile mix.
These recurring disasters demonstrated the tremendous economic stakes
involved in rope manufacturing—a single fire could destroy businesses that had
taken years to establish, wiping out not just buildings and equipment but also
the accumulated expertise of skilled ropemakers who represented generations of
craft knowledge.
Imperial Restrictions and
Revolutionary Necessity
As tensions between Britain and her American colonies escalated during
the 1760s and 1770s, rope manufacturing became entangled in the larger
conflicts over colonial economic autonomy. While British policy had long
encouraged hemp cultivation in the colonies (viewing it as a way to reduce
dependence on Russian hemp imports), Parliament was far less enthusiastic about
allowing colonists to develop their own rope manufacturing capacity that might
compete with English ropewalks.
This imperial ambivalence created
frustrating contradictions for colonial entrepreneurs. They were required to
grow hemp but discouraged from processing it into finished goods. They could
export raw fiber to Britain but found it difficult to obtain the equipment and
supplies needed for large-scale rope manufacturing in the colonies. These
restrictions, like the better-known prohibitions on American iron production
and textile manufacturing, reflected Britain's mercantilist vision of colonies
as sources of raw materials and markets for finished goods rather than as
autonomous economic entities.
When the Revolution finally came and trade with Britain was severed,
these restrictions created immediate crises. The military wanted tin items,
because they were inexpensive, lightweight, and durable. The tinware the
American navy and army needed wasn't easy to get. Until the war, most tin items
came from England. Relatively few tinmen lived in the colonies, and supplies of
raw material were limited by the British blockade. The same dynamic applied to
rope—suddenly, American forces needed vast quantities of cordage but faced
severe limitations in manufacturing capacity and raw material supplies.
Colonial ropemakers rose to meet this challenge through a combination of
innovation, improvisation, and sheer determination. They expanded existing
ropewalks, built new facilities, and developed techniques for working with
whatever materials they could obtain. Some colonial governments offered
bounties for hemp production, while revolutionary committees organized
campaigns to increase cultivation. The privateers who preyed on British
shipping also provided crucial supplies by capturing vessels laden with cordage
and sailcloth.
The Human Drama of the Ropewalk
The work of rope manufacturing was physically demanding and required
years of training to master. Young men typically entered the trade through
apprenticeships, spending four to six years learning the craft under master
ropemakers. They started with simple tasks—cleaning tools, organizing
materials, maintaining equipment—and gradually progressed to more skilled work
as they developed the strength, coordination, and judgment needed for quality
rope production.
Workers walked the length of a ropewalk as they twisted plant fibers into
rope by hand, a process that required both endurance and technique. A spinner
might walk backward down a quarter-mile building dozens of times each day,
maintaining consistent tension and twist while avoiding the many hazards of the
working environment. The work built distinctive muscle development and created
characteristic occupational injuries—ropemakers' hands became calloused and
scarred from handling rough fibers, while their backs and legs ached from the
constant walking.
Yet for all its physical demands, ropemaking also offered opportunities
for skilled workers to achieve economic independence and social respect. A
master ropemaker who established his own ropewalk could become a substantial
figure in his community, employing dozens of workers and supplying rope to
merchants, shipbuilders, and naval contractors. The strategic importance of
rope during the Revolutionary period enhanced the status of ropemakers, who
found themselves contributing directly to the war effort through their craft.
The Charlestown Legacy: America's
Great Ropewalk
The story of American rope manufacturing reached its culmination in the
construction of the Charlestown Navy Yard Ropewalk, which would become the
greatest rope manufacturing facility in the United States and a symbol of
American industrial achievement. In 1833, the Navy persuaded the US Congress on
the practicality of a single ropewalk supplying all the Navy's rope, reflecting
recognition that naval rope requirements demanded specialized facilities
operating at unprecedented scale.
The Navy asked architect Alexander Parris and machinist Daniel Treadwell
to design and outfit the Charlestown Navy Yard Ropewalk. Based on their plans,
the US Navy constructed the Ropewalk building: a quarter-mile long, one-and-two
story granite building with a slate roof. The length of the Ropewalk equaled
the height of the Empire State Building. The Ropewalk is 45 feet wide with
walls that are two-feet thick. The thick walls made this Greek-Revival
structure both formidable and fireproof.
Opened in 1838, the Navy Yard Ropewalk followed what is now Chelsea
Street for 1325 feet, allowing workers to produce rope up to a quarter mile in
length. The building's construction from granite reflected lessons learned from
the countless ropewalk fires that had plagued the industry—this facility would
be as fireproof as 19th-century technology could achieve.
By the time the Navy decided to make its own rope, ropewalks were
enclosed buildings, and steam engines mechanized many ropemaking tasks.
Initially steam-powered, the facility made use of a number of innovations
designed by local inventor Daniel Treadwell, transforming rope manufacturing
from a primarily manual craft into a mechanized industrial process.
Wartime Production and Women Workers
The Charlestown Ropewalk proved its worth during times of national
crisis, dramatically increasing production to meet military demands. The
Ropewalk experienced its highest level of productivity during World War II
(WWII). In 1942, the workers in the Ropewalk made 20 million pounds of rope.
Even after the transition from sail to steam in the later half of the 1800s,
ships still required miles of rope. A World War II battleship needed 34,000
feet of cordage and the Charlestown Navy Yard rapidly increased production
after Pearl Harbor to its highest levels during World War II.
Perhaps most remarkably, the wartime production surge created
unprecedented opportunities for women in rope manufacturing. As Navy Yard
workers entered the armed forces in WWII, the Navy hired women to take their
place in the Charlestown Navy Yard. While women became 17% of the Yard's
workforce, the proportion of women ropemakers was much higher (44%). This
dramatic shift demonstrated that the supposedly demanding physical work of rope
manufacturing could be successfully performed by workers regardless of gender—a
lesson that would contribute to broader changes in industrial employment
patterns during and after the war.
The End of an Era
The Navy Yard Ropewalk made rope for the US Navy from 1837 to 1971,
spanning 134 years of American naval history from the age of sail through two
world wars and into the era of nuclear-powered vessels. Yet by the 1950s, the
facility's future had become uncertain as Congress questioned whether the
government should continue operating industrial facilities that competed with
private industry.
In 1953, Congress launched an investigation and considered the
Charlestown Navy Yard Ropewalk for closure. Many, including master ropemaker
David Himmelfarb, argued to Congress that the Ropewalk served a number of
purposes from ropemaking to rope testing and development of new types of rope.
It was perhaps these other uses that kept the Ropewalk in operation until 1970.
The Ropewalk's survival through the 1950s and 1960s reflected its
evolution from pure manufacturing facility to research center. The Charlestown
Navy Yard was the center for considerable research into treated natural rope
and nylon rope in the 1950s and 60s. After 1962, only nylon rope was produced,
marking the complete transition from natural hemp fibers to synthetic
materials.
When the Ropewalk finally closed in December 1971, it marked the end of
an industrial tradition that stretched back to the earliest days of European
settlement in North America. Yet the building itself survived, becoming a
National Historic Landmark and serving as a tangible reminder of the crucial
role that rope manufacturing had played in American maritime history and
industrial development.
Legacy: The Thread That Runs Through
History
The story of colonial ropewalks and Revolutionary-era rope manufacturing
illuminates broader themes about American development, technological change,
and the relationship between mundane industries and grand historical
transformations. The rope that held together sailing vessels also held together
networks of trade, connected scattered military forces, and quite literally
suspended the physical infrastructure of maritime commerce.
Those long, narrow buildings where workers walked backward while spinning
hemp fibers represented more than just industrial facilities—they embodied a
distinctively American approach to solving practical problems through a
combination of traditional craft knowledge and innovative adaptation. When
British restrictions threatened to limit colonial rope production, American
ropemakers found ways to expand capacity and maintain supply. When war created
unprecedented demands, the industry responded through increased cultivation,
expanded facilities, and improved production techniques.
The workers who spent their days walking the length of ropewalks, hands
calloused from handling rough hemp fibers, were participating in one of the
essential activities that made American independence possible. Every rope they
produced helped equip another vessel, supply another military unit, or
facilitate another commercial transaction that built the economic foundation
for the new nation. Their craft may have lacked the dramatic appeal of
blacksmithing or the refined elegance of cabinetmaking, but its strategic
importance was undeniable.
As we commemorate 250 years of American independence, perhaps it's worth
remembering that revolutions require not just inspiring speeches and
battlefield heroics but also vast quantities of mundane materials produced
through patient, skilled labor in specialized facilities. The ropewalks of
colonial America, stretching their quarter-mile lengths across the landscape,
remind us that freedom was spun from hemp fibers and twisted into reality by
workers whose names we've mostly forgotten but whose contributions were
absolutely essential to the creation and survival of the new nation.
