Battle of Red Bank (1777)

The Battle of Red Bank, also known as the Battle of Fort Mercer, was fought on October 22, 1777, at Fort Mercer in Red Bank, present-day West Deptford Township, Gloucester County, New Jersey—not to be confused with the borough of Red Bank in Monmouth County. The engagement was a significant American victory during the American Revolutionary War, in which a force of approximately 400 Continental soldiers under Colonel Christopher Greene repelled a Hessian assault force of roughly 1,200 men under Colonel Carl Emil Kurt von Donop. The successful defense of Fort Mercer temporarily blocked British efforts to control the Delaware River and secure open supply lines to Philadelphia, which British forces had occupied the previous month.

Background

British forces under General William Howe had captured Philadelphia in September 1777, but possession of the city alone did not guarantee their strategic position. The Delaware River served as the primary supply artery for British forces in the city, and American fortifications along the river threatened to sever that lifeline entirely. Fort Mercer at Red Bank and Fort Mifflin on Mud Island in the river, together with a system of underwater obstructions known as chevaux-de-frise—iron-tipped wooden frames anchored to the riverbed—effectively denied British ships free passage to Philadelphia.

Fort Mercer had been constructed on the eastern bank of the Delaware and named in honor of Brigadier General Hugh Mercer, an American officer killed at the Battle of Princeton earlier that year. Polish-born military engineer Thaddeus Kościuszko, then serving in the Continental Army, contributed to the design and reinforcement of the fort's defenses, strengthening the earthworks and positioning artillery to maximize coverage of the river approaches. By the time the Hessians advanced in October, the fort's garrison had spent weeks improving its defenses, training its gun crews, and positioning artillery to command the approaches from multiple angles.

The Battle

Colonel Carl Emil Kurt von Donop commanded the Hessian assault force of approximately 1,200 troops dispatched to reduce Fort Mercer. An experienced professional officer, von Donop was confident that his numerically superior force could overwhelm the American garrison of roughly 400 men under Colonel Christopher Greene, a Rhode Island native who had previously served in the Continental Army's operations in the Northern Department. Von Donop reportedly declared before the assault that he would either take the fort or die in the attempt—a prophecy that proved accurate on both counts.

The Hessian force divided into two columns and advanced on the fort on the morning of October 22, 1777. Greene's defenders held their fire until the attackers were well within range of the fort's artillery. When the guns opened, the effect was devastating. The Hessian columns suffered severe casualties in the initial advance, and officers directing the assault were among the first to fall. Von Donop himself was gravely wounded during the fighting and died of his wounds three days later, on October 25, 1777, reportedly in the very house where he had established his field headquarters.

A second assault wave fared no better. American sharpshooters targeted Hessian officers and artillery crews, while the fort's elevated position and surrounding marshlands denied the attackers the ability to concentrate their force or find cover. After sustaining catastrophic losses, the surviving Hessian officers ordered a withdrawal. The entire engagement lasted only a matter of hours. American casualties numbered approximately 14 killed and 23 wounded; Hessian losses exceeded 400 killed or wounded, a casualty rate of roughly one-third of the entire attacking force.

Geography

Red Bank sits on the eastern bank of the Delaware River in what is now West Deptford Township, Gloucester County, New Jersey. The site was chosen deliberately for its commanding position: a high bluff above the river provided defenders with clear sight lines over the water and the approaches below, while surrounding marshlands and dense woodland restricted the avenues of advance available to any attacking force. These natural features compounded the difficulty facing von Donop's troops, who were forced to cross open ground under fire with limited cover and no ability to maneuver freely.

The Delaware River at this location is both wide and deep, forming a critical corridor for military and commercial movement between the Atlantic coast and the interior. Control of the Red Bank stretch of the river, combined with the underwater chevaux-de-frise obstructions and the garrison at Fort Mifflin on the opposite bank, effectively denied British naval forces freedom of movement. The interplay of river currents, tidal fluctuations, and the elevated gun positions at Fort Mercer shaped the tactical options available to both sides throughout the engagement. The terrain, in short, amplified the effectiveness of a small defending force far beyond what raw numbers alone would suggest.

Aftermath

Despite the American victory at Red Bank, the broader strategic situation on the Delaware River remained under pressure. British forces continued their efforts to open the river and secure supply lines to Philadelphia. Fort Mifflin on Mud Island endured a prolonged and intense bombardment throughout late October and into November 1777 before its garrison evacuated on November 15. With Fort Mifflin no longer tenable, Fort Mercer became isolated, and American commanders ordered its evacuation on November 21, 1777, to prevent the garrison from being cut off and captured.

The British subsequently cleared the chevaux-de-frise obstructions and opened the Delaware River to their supply ships, consolidating their hold on Philadelphia through the winter of 1777–1778. However, the determined American resistance at Red Bank and Fort Mifflin had delayed British logistics for weeks, complicated Howe's planning, and inflicted significant casualties on experienced Hessian forces. The engagements are widely regarded as demonstrating the effectiveness of well-prepared defensive positions against numerically superior attackers, and the death of von Donop—a senior and experienced Hessian commander—represented a notable loss for British forces.

Notable Commanders

Colonel Christopher Greene commanded the American garrison at Fort Mercer throughout the battle. A native of Rhode Island, Greene had served in the Continental Army since the early years of the war and brought substantial experience to the defense of the fort. His decision to hold fire until the Hessian columns were fully exposed, combined with his effective use of artillery and sharpshooters, proved decisive in repelling the assault. Greene continued his service in the Continental Army after Red Bank, participating in subsequent campaigns before being killed on May 14, 1781, during a raid by Loyalist forces near Croton, New York. His conduct at Fort Mercer remains his most celebrated command.

Colonel Carl Emil Kurt von Donop, who led the Hessian assault, was among the most experienced professional officers in British employ during the Philadelphia campaign. His death from wounds sustained at Red Bank on October 25, 1777, removed a capable field commander from the British order of battle and underscored the cost of the failed assault on American fortifications.

Cultural Legacy

The Battle of Red Bank holds a significant place in New Jersey's Revolutionary War heritage. Red Bank Battlefield Park, administered by Gloucester County and located on the site of the original fortification in West Deptford Township, preserves the grounds where the engagement took place. The park features interpretive exhibits, walking trails, and a museum with artifacts and primary source materials related to the battle, the fort's garrison, and the broader Delaware River defense campaign. Periodic reenactments and educational programs draw both local residents and visitors from across the region.

The battle has become a touchstone in how New Jersey communities understand their role in the American Revolution. Local historical societies and preservation groups have worked to maintain awareness of the engagement, particularly given the tendency among casual visitors to conflate Red Bank in Gloucester County with the more widely known borough of Red Bank in Monmouth County. The battlefield park's interpretive materials address this geographic distinction directly, situating the site within the specific history of Gloucester County and the Delaware River valley.

Visiting Red Bank Battlefield Park

Red Bank Battlefield Park is located in West Deptford Township, Gloucester County, New Jersey. The park is accessible by car via Interstate 295 and Route 44; on-site parking is available. Public transportation options to the park are limited, and most visitors arrive by private vehicle.
