In the one hundred years between the settlement of Charles Town on Oyster Point in 1680 and the American surrender of Charleston to the British Army in 1780, South Carolina’s provincial legislature directed massive amounts of money, resources, and labor toward the erection of defensive fortifications for the protection of the colony’s capital and main port. During that long era, South Carolinians carefully watched the movements of our Spanish and French neighbors in St. Augustine, Havana, Biloxi, Mobile, and New Orleans, ever mindful of the treat of foreign invasion. The Treaty of Paris in 1763, signed by Britain, France, and Spain, marked the beginning of an era of unprecedented peace and prosperity in the American colonies. For the first time in our colonial history, South Carolinians no longer worried about the threat of foreign invasion, and the commerce of our ports expanded rapidly.

The rift between the colonists and Britain in 1775 brought a sudden end to what had been a very prosperous decade, however, and induced South Carolinians to make rapid preparations for an imminent engagement with a new enemy. After refurbishing and expanding our fortifications, Charleston was eventually overwhelmed by the might of the British Army and capitulated on 12 May 1780. Between that time and the British evacuation of Charleston on 14 December 1782, the occupying forces maintained and even expanded some of the town’s urban fortifications as a precaution against an American counterattack. But the dawning of the year 1783 brought a fresh outlook to South Carolina. All of our enemies had retreated, and, for the first time since the founding of the colony, South Carolina’s sovereignty stood unchallenged on the world stage. At that moment our legislators, military leaders, and private citizens asked themselves, what should become of the long-standing urban fortifications crowding our principal port and capital town?

In retrospect, we look back at the year 1783 as the official beginning of the happy sovereignty of the United States of America, but at that time not everyone was so sanguine about our future. Following legislative debates and petitions from the merchant community, South Carolina’s General Assembly voted in March 1783 to preserve, maintain, and even expand Charleston’s urban fortifications. In the meantime, peace negotiations were proceeding in Paris between American and British diplomats, and the news of their progress was amply reported in our local newspapers.  When the City of Charleston was finally incorporated on 13 August 1783, local conversations began about who had jurisdiction over the urban defenses, and how long they might remain. Finally, at the end of its spring session in late March 1784, the South Carolina legislature voted to divest the state’s interest in Charleston’s urban fortifications. The state appointed three commissioners to manage the process of surveying, subdividing, and selling “the public lands whereon the forts and fortifications were erected, and low-water lots in Charleston,” as well as a few other non-military sites. Commencing in April 1784 and continuing to August 1789, these commissioners superintended the relatively rapid removal of the urban fortifications that had preoccupied South Carolina’s public treasury for more than a century.

The significance of this process of fortification removal, or demilitarization, for the City of Charleston cannot be overstated. The Charleston that has garnered so much devotion and praise from its denizens and tourists alike is the product of generations of civilian activity, a marriage of private enterprise and public appropriations. But the present landscape of Charleston—its infrastructure and its built environment—was shaped in part by the dominating presence of our early fortifications and by their removal in the 1780s. Understanding the physical evolution of Charleston thus requires an understanding of the physical growth of the now-absent fortifications. Fortunately for us, the five-year process of dismantling the fortifications generated a paper trail that provides important information about the location, dimensions, materials, and construction of the old works. Such information, combined with documentary evidence from colonial-era records, helps us understand how and where the fortifications were built, but it doesn’t answer all the lingering questions. The absence of many crucial documents has been a constant source of frustration in our efforts to research this topic. It is somewhat comforting, though, to see that in the 1780s some of the best legal minds in South Carolina were as confused about the legal title to some lands fortified in the colonial era as I am today.

The story of the removal of Charleston’s urban defenses forms the final installment of our 2014 lecture series on Charleston’s colonial fortifications. Please join me for a program titled

Pedestrians strolling past the swanky restaurants on Charleston’s upper King Street and promenading through the Farmers’ Market in Marion Square probably have no idea they’re treading through the heavily-fortified siege lines that once defined one of the most important battles of the American Revolution. A relatively new historical marker on the east side of King Street in the square commemorates the protracted British siege of Charleston in the spring of 1780, but it’s a minuscule reminder of a much larger scene that requires a lot of imagination to visualize. So, where were the siege lines of that historic battle, and what sorts of fortifications did the opposing forces erect? Two hundred and thirty-four years after the siege, the answers to these questions have been obscured by generations of development, but recent investigations are beginning to make the scene a bit clearer.

First, it is important to state that anyone interested in this topic should begin by reading Carl Borick’s book, A Gallant Defense: The Siege of Charleston, 1780 (University of South Carolina Press, 2003). This book provides excellent descriptions and analysis of the battle, based entirely on primary source material, and guides the reader through the many months of turmoil and bloodshed leading to the American surrender of Charleston on 12 May 1780. Mr. Borick’s book does not include a detailed analysis of the fortifications, however, because such an investigation would have derailed his book from its larger theme.

Working towards my own book on the urban fortifications of early Charleston, however, I’ve spent a lot of time gathering fragmentary details about these fortifications from surviving archival resources and the accounts of various eye witnesses to the siege. In addition, I’ve acquired copies of several manuscript maps of the era 1775–1783 that provide visual clues that help elucidate the documentary evidence. There are still more historical documents and maps out there, but locating them and obtaining copies often takes time. Nevertheless, a variety of manuscript maps from archives such as the British Library, the National Archives of the United Kingdom, the Clements Library at the University of Michigan, the Huntington Library in California, Dartmouth University Library, the Library of Congress, the South Carolina Historical Society, and of course the South Carolina Department of Archives and History, depict various parts of the suburban battlefield that is now part of urban Charleston.

Taken together, these maps illustrate, with a reasonable degree of uniformity, the many layers of fortifications employed by both sides. The American defensive lines stretched across the peninsula from the Ashley to the Cooper River, standing in ranks of graduated height from an artificial canal between John and Ann Streets to the mighty Horn Work with its back against the town limit (Boundary Street, now Calhoun Street). After sailing up the rivers and disembarking on the northern “neck” of the peninsula, the British army crept southward and encamped beyond the range of the American guns. At the beginning of April 1780, they began digging a series of siege trenches or “parallels” that zig-zagged southward from Columbus Street to the Americans’ artificial canal between John and Ann Streets. By the time British and Hessian troops drained the canal and penetrated the American defensive lines, just south of the modern intersection of King and John Streets, the end of the siege was a foregone conclusion.

Most of the aforementioned maps are covered by copyrights held by their respective institutions, and a sense of scholastic respect prevents me from posting them on this website. I will, however, direct readers to a very interesting French map held by the Library of Congress that is available online and downloadable. The manuscript map in question is not signed or dated, but it appears to be the work of Colonel Louis Antoine Jean Baptiste de Cambray-Digny (1751–1822), a French engineer who served in the American army in Pennsylvania, New Jersey, Maryland, North Carolina, and Georgia before being captured by the British in Charleston in 1780. Col. de Cambray, as he was known to the South Carolina legislature in Charleston, superintended the American fortifications during the siege, and the map held at the Library of Congress includes his two-paragraph caption (in French, naturellement) that gives a wonderful description of the siege and the American fortifications. A later copy of this map (with a much abbreviated caption) was published by George W. Williams in the South Carolina Historical Magazine in April 1975 (see my bibliography), but the map at the Library of Congress includes valuable, unpublished information about the fortifications. I encourage you to click on the image of the map above and read Col. de Cambray’s caption. If you need a bit of help, here’s my translation:

­Plan of the town of Charlestown of its retrenchments and of the siege made by the English in 1780.

The night of the first of April they opened their trenches. The 10th they summoned the town [to surrender]. The 13th the 1st parallel and its batteries were finished, and began to cannonade. The 18th the 2nd parallel was finished. The 24th the besiegers mad­e a sortie to the extreme right of the 3rd parallel. The 8th of May they summoned the town to surrender. The 3rd parallel and its batteries were completed and commenced a demolishing fire [“á battre en brêche”]. The 11th they made a sap very close to the salient angle of the advance battery on the left, ­and made a passage through the advance moat from which the water had been previously drained. The 13th [sic, the 12th] the town capitulated.

The retrenchments [i.e., defensive lines] of Charlestown consisted of detached redans and curtains, the parapets 7 feet high, 16 feet thick; the moat was 12 feet deep and 26 wide. It was double palisaded, there were three rows of wells [“puits,” or trous-de-loup] beyond and some strong abatis; the contested ground [“le front attaquée,” i.e., the space between the two armies] was covered by a moat full of water 30 feet wide. The retrenchments were made in haste in less than 4 weeks in 1779, and saved the town from invasion by the English under Gen. Prevost. When the English disembarked on Johns Island there were only 200 men in garrison in the town; there was not a single cannon mounted, the abatis had been burned during the winter and had not yet been remade. When the English began their entrenchments, the garrison was about 1200 men, the militia and the sailors did nothing during the whole siege the defense was always directed by Continental troops which extended from one river to the other. During the siege the English shot 10,000 bombs 16,000 bullets and 150 carcasses. The defenders were reduced to live on nothing but rice and molasses for 4 days before the town capitulated. The garrison amounted at that time numbered 1900 [illegible] including sick, injured, servants etc. The English had at the time of the reduction 13,000 men, perfectly enveloping the town by sea and by land, and could [illegble] with success to land in the town which the defenders had guarded so vigorously.

The published diaries and memoirs of several other participants in the 1780 siege of Charleston, including those of Henry Clinton, Banastre Tarleton, Johann Hinrichs, Johann Ewald, and William Moultrie, provide additional details that help us imagine the scene. Walking around the environs of Charleston’s King Street and Marion Square, however, the modern built environment makes it difficult to visualize the battlefield of 1780. I’m in the process of attempting to overlay historic maps onto recent satellite images of Charleston, and this endeavor can prove to be very illuminating. If you’d like to see those overlays and learn more about the siege of 1780, please join me for a program titled:

“Charleston’s Fortifications of the

American Revolution, 1775–1783″

In October 2013 Charleston’s Post and Courier ran a front-page story about my research on the “Horn Work,” a large tabby fortification that once straddled King Street and served as the gateway into the town.  As a result of that press coverage, we had a very large turnout for my 2013 “Horn Work” presentation at CCPL. In case you missed that event, we’re offering two ways to catch up on your knowledge of Charleston’s largest fortification. First, you can watch last year’s presentation at your leisure via the following YouTube link:

Second, I’m presenting an updated version of this lecture at CCPL on Wednesday, October 22nd at 6 p.m. What’s new for 2014? I’ve been tinkering with my three-dimensional model of the Horn Work in an effort to render its size and materials more accurately. I’ve also gathered some new information from the British Library about Lt. Col. Henry Bouquet‘s role in convincing the South Carolina General Assembly to fund the construction of this important fortification project. Bouquet arrived in Charleston in mid-June 1757 as commander of the first battalion of the newly-formed 60th Regiment of Foot, better known as the “Royal Americans.” Bouquet’s surviving correspondence also reveals that in August 1757 he sent an illustrated plan of Charleston’s new fortifications to his superior officer, John Campbell, the 4th Earl of Loudoun. Many of the earl’s papers from the era of the “French and Indian War” survive in scattered archives, so I’ve begun a search for this forgotten 1757 treasure.

Archival sources at the British Library also provide “new” information about Lieutenant Emanuel Hess, the young Swiss engineer who accompanied the “Royal Americans” to South Carolina in 1757. Within a period of less than six months, Lieutenant Hess designed a series of new fortifications for Charleston, James Island, and Beaufort. After supervising the initial stages of these construction projects, Lt. Hess and the rest of the Royal Americans sailed from Charleston to Philadelphia in the late spring of 1758. Lt. Col. Bouquet then marched his troops towards the French at Fort Duquesne, but Lt. Hess fell ill and was left behind in Lancaster, Pennsylvania. There he died of tuberculosis and was buried on 22 February 1759.

If you’d like to learn more about Lieutenant’s Hess’s “Horn Work” in Charleston, and the other fortifications he designed for South Carolina, please join me for a program titled:

William De Brahm’s tenure in South Carolina was as dramatic as it was brief. Within a period of five years between 1752 and 1757 he drafted several different audaciously sophisticated plans for fortifying urban Charleston, charmed the doubting General Assembly, and ultimately roused the contempt of most of his supporters. Along the way he left a paper trail that provides fascinating insight into the most intensive period of fortification construction in pre-Revolutionary Charleston.

The German-born De Brahm initially came to British North America to work as a surveyor for the colony of Georgia, but South Carolina’s governor, James Glen, lured him to move to Charleston with promises of a lucrative contract to design and build fortifications for the port town. Although Governor Glen’s scheme was initially rebuked by the South Carolina legislature, the outbreak of fresh hostilities Between Britain and France—what we now call the French and Indian War—convinced our politicians of the urgent need to repair and expand Charleston’s aging fortifications.

De Brahm's ca. 1755 plan included a fortified canal connecting the Ashley and Cooper Rivers

De Brahm’s ca. 1755 plan for a fortified canal connecting the Ashley and Cooper Rivers

De Brahm’s designs for fortifying Charleston survive among archival collections at the National Archive of the United Kingdom and at the British Library. A total of six drawings survive, illustrating De Brahm’s proposed defensive works for urban Charleston, Fort Johnson on James Island, and a “Fortified Canal across the Neck from Ashley to Cooper River.” From these documents we see not only De Brahm’s considerable skill as a draftsman, but also the depth of his training and understanding of the science of military architecture.

Encouraged by Governor Glen and finally approved by the General Assembly, De Brahm commenced work in 1755 to transform the peninsula of Charleston into the most sophisticated military enceinte in British North America. If he had completed this project, Charleston would have become an island, separated from “the neck” of the peninsula by a fortified canal flanked by two small forts. But De Brahm’s work dragged on at a snail’s pace while the war with France move increasingly northward. By 1757 it was clear that the Canadian frontier was the epicenter of the war, and the perceived need for coastal defenses in South Carolina diminished. De Brahm’s elaborate new works for Charleston were already behind schedule and over budget, and in 1757 he learned that his services were no longer needed in South Carolina.

Fortunately for us, De Brahm left a robust paper trail of his activities in South Carolina. Many (but not all) of the drawings he made in Charleston survive in British archives, and in 1773 De Brahm presented an illustrated summary of his work in South Carolina and elsewhere to his ultimate employer, King George III. From these records, combined with accounts and descriptions in the surviving legislative records of colonial South Carolina, we can learn much about the ambitious efforts to expand Charleston’s fortifications in the 1750s. This era forms one of the most fascinating and well-documented chapters in the fortification history of urban Charleston, and the projects set in motion by De Brahm had long-lasting ramifications for the growth of the city’s built environment.

Fort Washington, erected in late 1814 at the east end of the "The Lines" of Charleston.

Fort Washington, erected in late 1814 at the east end of the “The Lines” of Charleston.

Technically speaking, the mission of the Mayor’s Walled City Task Force is to raise awareness about the colonial-era fortifications erected in urban Charleston. But I’ll go out on a limb for a moment and guess that readers of this blog might also be interested in learning about some of Charleston’s post-colonial fortifications. Shortly after Britain and France declared war on each other in 1793, the South Carolina government began erecting new fortifications (such as Fort Mechanic in 1794 and Fort Pinckney in 1798) to protect Charleston against possible incursions of either of these dueling nations. As the United States drifted towards war with Britain in the early nineteenth century, local leaders took further steps to defend our port city. Besides improving Charleston’s existing harbor defenses (consisting of forts Johnson, Moultrie, and Pinckney), our intrepid citizens erected in 1814 a significant line of earthwork and brick fortifications across the “neck” of the peninsula, connecting the Ashley and Cooper Rivers. This half-mile-long, zig-zag entrenchment and moat was intended to defend the city against any hostile attempts to attack the city from the north, as the British army had done in the spring of 1780.

This September we commemorate the 200th anniversary of that forgotten line of fortifications. No trace of “The Lines,” as they were commonly called, survives above the surface of modern Charleston, but our modern Line Street marks the site of this once-formidable barrier. I’ve written a few more words about the history of these War of 1812 fortifications at my other blog, The Charleston Time Machine, and I’ll be presenting an overview of the construction of “The Lines” next week. If you’d like to learn more about this little-known fortification episode in the history of our fair city, please join me for an illustrated program titled:

A map of Charleston's new northern wall of 1745, and the town's second gate (in yellow) at the modern intersection of Market and King Streets.

Charleston’s new northern wall of 1745 (red) and its moat (blue), and the town’s second gate (yellow) at the modern intersection of Market and King Streets.

For most of our colonial era, visitors walking or riding into urban Charleston by land had but one avenue of entry: the so-called “high road” or “broad path” that we now call King Street. Between late 1703 and the early 1730s, the entrance into town was controlled by a ravelin and gate at what is now the intersection of Meeting and Broad Streets. Following the outbreak of a new war between Britain and Spain in 1739, the so-called “War of Jenkins’ Ear,” our provincial legislature commenced building new fortifications around the perimeter of Charleston.

The culmination of this defensive project was the completion ca. 1745 of a new earthen wall and moat measuring approximately 3,400 linear feet along the town’s northern boundary, with a new gate in the center of the line. Beginning at its eastern flank, the wall commenced with a battery or bastion next to a marsh at the modern intersection of Market and Church Streets and ran westward approximately 2,000 feet to another bastion at the intersection of what is now Market Street and Beaufain Street (then the town’s northern boundary). From that point the wall turned southwestwardly and ran approximately 700 feet to a third bastion at the modern intersection of Magazine and Franklin Streets. There the wall turned again and headed nearly due south a further 700 feet or so, terminating in a tidal inlet extending from the Ashley River.

By tracing this fortification path on a modern map, as seen in the photo above, we are reminded that the land mass of the Charleston peninsula has grown quite a bit since the 1740s thanks to various landfill projects. The eastern and southwestern ends of this wall were once connected to muddy tidal inlets that provided the town with natural barriers against any invading forces. Thus between its construction in 1745 and its demotion in 1765, this northern wall and moat funneled all traffic in and out of the town through a single portal—a ravelin with two drawbridges and a gate located at the modern intersection of Market and King Streets. This “New Gate,” as it was briefly known, was the second and shortest-lived of Charleston’s three colonial-era town gates. No visible reminders of it appear on our modern landscape, and there are no markers to commemorate its long-forgotten existence. If you have ever walked along Market Street between Church and Archdale Streets, however, you’ve actually walked along the broad moat fronting this 1740s fortification wall.

A 1780 illustration of Broughton's Battery at the southernmost tip of the Charleston peninsula

A 1780 illustration of Broughton’s Battery at the southernmost tip of the Charleston peninsula

Nearly a year an a half ago, in April 2013, I presented a lecture on Broughton’s Battery, a formidable brick fortification that stood at the confluence of the Ashley and Cooper Rivers from 1736 to 1784. At that time I proposed that this little-known work, which was designed by Swiss engineer Gabriel Bernard, was one of the largest and most significant fortifications constructed in colonial Charleston. It was designed to mount up to forty cannon, although South Carolina’s artillery-starved colonial militia could scarcely afford to mount more than 25 or 30 guns at the site. Unfortunately for us, there is scant extant information about the battery’s design and precise location. Since April 2013, however, I’ve gathered a lot more information about the history of the real estate immediately surrounding the battery, which will help us determine its location more exactly. I’ve also acquired a couple of new, informative images. The image displayed here, for example, is a very small detail from a hand-drawn 1780 map of Charleston’s defenses, the original of which is in the National Archives of the United Kingdom. In short, we know a lot more about Broughton’s Battery in July 2014 than we did a year and a half ago. Want to hear all the latest news? Please join me Wednesday, July 23d for:
