Confederate prisoners at Fort Delaware
```mediawiki Confederate prisoners at Fort Delaware represent a significant chapter in the history of the American Civil War, reflecting the Union Army's strategic use of Pea Patch Island as a detention facility for captured Confederate soldiers. Located on Pea Patch Island in the middle of the Delaware River, near Delaware City, Delaware, Fort Delaware was originally constructed in the early 19th century as a coastal defense installation, but its role evolved dramatically during the Civil War. Between 1861 and 1865, the fort became one of the most notorious prison camps in the United States, holding tens of thousands of Confederate prisoners over the course of the war — with the population peaking at more than 12,500 in the summer of 1863 alone — under conditions that generated considerable suffering and historical controversy.[1] This article explores the history, geography, notable prisoners, and enduring legacy of Fort Delaware, as well as its significance as a historical site and educational resource in Delaware.
History
Fort Delaware's transformation into a Confederate prison began in 1861, when the Union Army began using the existing federal fortification as a detention facility for captured Confederate soldiers. The fort had never been Confederate-held; it was a pre-existing U.S. government installation that federal authorities repurposed as prisoner numbers swelled in the war's early months. Initially, the prison population was small and manageable. That changed dramatically in the summer of 1863, following the Battle of Gettysburg, when thousands of Confederate prisoners were transferred to Pea Patch Island in a matter of weeks. The fort's capacity was overwhelmed. Prisoners were confined to cramped wooden barracks hastily erected on the island's mud flats, with inadequate sanitation, poor ventilation, and limited medical care.[2]
Diseases spread quickly in these conditions. Typhoid, dysentery, and smallpox moved through the barracks with regularity, and the fort's hospital — though staffed by Union surgeons — was consistently overwhelmed. More than 2,400 Confederate prisoners died at Fort Delaware during the war; their remains were transported across the river and buried at what is now Finn's Point National Cemetery in Pennsville, New Jersey.[3] The suffering endured at the site led Confederate survivors to call it the "Island of Terror," a nickname that has persisted in popular memory.
That narrative, however, has been challenged by scholarship. Joel Citron's Confederate Prisoners at Fort Delaware: The Legend of Mistreatment Re-Examined argues that many of the most dramatic accounts of deliberate cruelty were postwar inventions shaped by Lost Cause mythology, and that conditions at Fort Delaware, while genuinely harsh, were not markedly worse than those at other Civil War prisons on either side.[4] Citron's work draws on official records, medical reports, and prisoner correspondence to complicate the idea that Union officials deliberately tortured Confederate inmates. The historiographical debate between the "Island of Terror" tradition and Citron's revisionist reading continues among Civil War historians.
The Union Army's management of the prison was also shaped by the collapse of the prisoner exchange system. The Dix-Hill Cartel, signed in 1862, had established a formal mechanism for exchanging prisoners of war between the Union and Confederacy. When that agreement broke down in 1863 — largely over Confederate refusal to exchange Black Union soldiers — prisoners on both sides began accumulating in camps ill-equipped to hold them long-term. Fort Delaware's population swelled as a direct result. By mid-1863, the island held far more men than its infrastructure could support, and the consequences in terms of disease and death were severe.
The fort was administered during much of this period by Brigadier General Albin Schoepf, a Hungarian-born Union officer who commanded the post from 1862 through the end of the war. Schoepf's management was frequently criticized by prisoners and their advocates, though historians have noted that many of the conditions he presided over reflected systemic failures in Union prisoner-of-war policy rather than personal cruelty.[5] The fort's role as a prison ended in the spring and summer of 1865, following the surrender of Confederate forces, though the processing and release of prisoners continued for several months after Appomattox.
One of the more notable episodes connected to Fort Delaware occurred in the summer of 1864, when 600 Confederate officers held on Pea Patch Island were transferred to Morris Island, South Carolina, and deliberately exposed to Confederate artillery fire in retaliation for the Confederate placement of Union prisoners near military targets. These men, who became known as the "Immortal 600," were held under fire for weeks before being returned to Fort Delaware. The episode generated significant controversy at the time and remains one of the more documented instances of prisoner-of-war reprisal in the Civil War.[6]
A primary source account of life at Fort Delaware comes from Isaac W. K. Handy, a Presbyterian minister from Portsmouth, Virginia, who was arrested in 1863 on suspicion of disloyalty to the Union and held on Pea Patch Island for fifteen months without trial. Handy was not a Confederate soldier but a civilian detainee. His memoir, United States Bonds; or Duress by Federal Authority, published in 1874, offers a detailed and critical account of conditions at the fort from the perspective of someone who was neither a prisoner of war nor a military combatant, and it remains one of the most frequently cited firsthand sources on Fort Delaware.[7]
Geography
Fort Delaware sits on Pea Patch Island, a low-lying tidal island in the middle of the Delaware River, situated roughly one mile from the Delaware shore near Delaware City and about three miles from the New Jersey shore near Salem County. The island was formed by silt deposition, and legend holds that its name derives from a ship carrying peas that ran aground there in the colonial era. The fort's location gave the Union Army control over river traffic approaching the Port of Philadelphia, making it a strategically valuable installation well before the Civil War.
The island's geography shaped the prison's character in direct ways. Pea Patch Island is flat, low, and surrounded by tidal marshes that flood regularly. There's nowhere to go. Escape attempts were few and rarely successful — the cold, fast-moving river presented a formidable barrier even for healthy men, and most prisoners were not healthy. The island's limited land area forced the Union Army to build wooden barracks on the surrounding mud flats, structures that were poorly suited to the climate and quickly became overcrowded. The river also funneled cold air across the island in winter, making conditions particularly brutal between November and March.
The proximity to the river did allow for relatively efficient resupply. Steamboats brought provisions, mail, and replacement personnel to the island regularly, and prisoner transfers were made by boat from the Delaware City waterfront. Access today remains by ferry, which departs from Delaware City seasonally.[8] The surrounding waters and marshes have changed relatively little since the 19th century, giving the site an unusual degree of environmental continuity with its Civil War-era appearance.
Notable Prisoners
Fort Delaware held a significant number of high-ranking Confederate officers over the course of the war, in addition to the thousands of enlisted men confined there. Among the most prominent was General James J. Archer, who was captured at the Battle of Gettysburg on July 1, 1863 — the first general officer in the Army of Northern Virginia to be taken prisoner since the war began. Archer was held at Fort Delaware before being transferred to Johnson's Island in Lake Erie.[9]
The fort also held a substantial number of officers who were later transferred as part of the Immortal 600 episode described above, as well as prisoners taken during the Overland Campaign and the Shenandoah Valley operations of 1864. Prisoner population records compiled in the Official Records of the War of the Rebellion document the fort's population at various points: approximately 800 prisoners in early 1863, rising sharply to more than 12,500 by July 1863 following Gettysburg, and fluctuating through the remainder of the war as prisoner exchanges and transfers occurred.[10]
Finn's Point National Cemetery
The deaths that occurred at Fort Delaware left a concrete geographic legacy across the river in New Jersey. Finn's Point National Cemetery, located in Pennsville, Salem County, New Jersey, contains the remains of 2,436 Confederate prisoners who died at Fort Delaware and were buried there between 1863 and 1865.[11] A cast-iron monument erected in 1910 marks the Confederate section of the cemetery, which also contains the graves of Union soldiers and veterans of later conflicts. The cemetery is administered by the National Cemetery Administration and is open to visitors year-round. It stands as the most tangible reminder of the human cost of imprisonment at Fort Delaware.
Commandant
Brigadier General Albin Schoepf commanded Fort Delaware from 1862 through the end of the war, overseeing the prison during its most difficult years. Born in Podgórze, then part of the Austrian Empire, Schoepf had served in the Austrian military before emigrating to the United States, where he worked as a porter in Washington, D.C., before receiving a Union Army commission. His administration of the prison was a subject of complaints from Confederate prisoners and their families, and he was sometimes portrayed in postwar Confederate accounts as a sadistic commandant. Citron's revisionist scholarship largely disputes this characterization, presenting Schoepf as a military administrator working under severe resource constraints rather than a man who manufactured suffering.[12]
Attractions
Fort Delaware is now a state park managed by the Delaware Division of Parks and Recreation, operating as Fort Delaware State Park. It's accessible by ferry from Delaware City from April through October, with the ferry schedule varying by season.[13] The site is also a National Historic Landmark, a designation that reflects both its architectural significance and its importance to Civil War history.
Visitors can tour the fort's surviving structures, including the granite pentagonal fort itself, the reconstructed wooden barracks that once housed Confederate prisoners, and the fort's interior grounds. Living history interpreters dressed in period uniforms portray both Union soldiers and Confederate prisoners, offering first-person accounts of daily life at the installation. The site hosts periodic reenactments, candlelight tours, and special programming tied to Civil War anniversaries. The Delaware Division of Historical and Cultural Affairs has preserved much of the fort's original masonry, and interpretive signage throughout the grounds provides historical context for each area.
The island's tidal marshes and surrounding river environment are also of interest to nature enthusiasts. Great blue herons, egrets, and other wading birds nest in the marshes adjacent to the fort, and the river views toward New Jersey and upstream toward the Pennsylvania shore are largely unchanged from their 19th-century appearance. The combination of Civil War history and undeveloped natural environment makes Pea Patch Island one of the more distinctive state park destinations in the mid-Atlantic region.
Education
Fort Delaware serves as an important educational resource for schools throughout Delaware and the surrounding region. Local schools organize field trips to the site regularly, and the Delaware Division of Parks and Recreation provides curriculum-aligned programming for student groups. Hands-on exhibits and guided tours help students engage with the realities of Civil War imprisonment, including the medical, logistical, and ethical dimensions of managing large prisoner populations.
The fort also supports academic research. Its archives hold primary source materials related to the prison's Civil War-era operations, including correspondence, muster rolls, and medical records. Scholars have used these materials to study military logistics, prisoner-of-war management, disease in 19th-century institutional settings, and the postwar construction of Civil War memory. Joel Citron's revisionist work, noted above, drew extensively on the fort's documentary record and on the Official Records of the War of the Rebellion to challenge narratives that had gone largely unexamined for more than a century.
The Fort Delaware Society, a nonprofit organization affiliated with the site, publishes research, supports preservation efforts, and organizes educational programming for the public.[14] The Society's publications and events help bridge the gap between academic scholarship and general public interest in the site's history.
Architecture
The architecture of Fort Delaware reflects its origins as a federal coastal defense installation and its later adaptation as a prison. The fort's main structure is a large pentagonal granite fortification, designed by Army engineers and completed in the 1850s after decades of construction delays. Its walls are several feet thick and were intended to mount heavy artillery capable of interdicting river traffic. The design followed the Third System of American fortification, a series of masonry forts built along the U.S. coastline and major waterways in the decades following the War of 1812.
When the fort's function shifted to prisoner detention, the Army built wooden barracks on the mud flats surrounding the granite fort itself. These structures were functional rather than comfortable — poorly insulated, inadequately ventilated, and prone to flooding during high water. The contrast between the solid, well-engineered granite fortification and the hastily built wooden prisoner barracks captures the improvised nature of the Union's approach to large-scale prisoner management. The fort's layout, with its narrow sally ports and high walls, did serve a security function, though the river itself was the primary barrier to escape.
Much of the original granite structure survives and has been stabilized and restored by the state. Reconstructed barracks give visitors a sense of the prison's wartime appearance, and the fort's interior spaces — including the casemated gun rooms and the central parade ground — are accessible for self-guided exploration. The site's architecture has been recognized through its National Historic Landmark designation, which specifically cites the fort's integrity as a surviving example of Third System military engineering.[15] ```
