In order to make up for a shortage of bread in his supplies, Stewart had been sending out foraging parties each morning to dig up yams, unarmed except for a small guard detail. At around 8 am on September 8, Captain John Coffin and a detachment of his South Carolina
Loyalist cavalry were reconnoitring ahead of Stewart's main force when he encountered a mounted American scouting party under Major John Armstrong. Coffin pursued Armstrong, who led him into an ambush. Attacked by
Henry Lee's
2nd Partisan Corps, Coffin escaped but left 4 or 5 of his men killed and 40 more captured. Greene's force, with around 2,200 men, now approached Stewart's camp while Stewart, warned by Coffin, deployed his force. When the Americans realized they were approaching the British force, they formed three lines, with the militia in front with 2 3-pounders, followed by the Maryland, Virginia, and North Carolina Continentals with 2 6-pounders, with the Delaware Regiment and Washington in reserve. The Americans started the attack at 9 am with artillery and an advance by the militia. This line consisted of, left to right, Hampton, Henderson, Pickens, de Malmedy, Polk, Marion, Lee's infantry and then Lee's Cavalry. They were opposed by the British Line consisting of, left to right, Coffin, 64th, 63rd, New Jersey Volunteers, New York Volunteers, 84th, De Lancey's, 3rd, and Marjoribanks.
Hand-to-hand combat ensued when the Militia closed with the British Line. Some militia panicked while some held firm, able to fire 17 times, before ordered back and replaced by the North Carolina Continentals in a 'passage of lines". The North Carolina Continentals halted the British advance but were forced back by a British bayonet charge, only to reform and halt the British a second time. Greene then ordered the Maryland and Virginia Continentals forward in another passage of lines, forcing the British back towards their camp. However, two areas of British resistance remained, one under Maj. Henry Sheridan at the Brick House, which included a
swivel gun, and another under Maj. Marjoribanks on the northern flank. Washington's cavalry tried to dislodge Marjoribanks, but Washington was unhorsed, wounded and taken prisoner, sitting out the remainder of the war. Marjoribanks then retreated towards the Brick House. The Brick House now became the focal point of the battle, and when an American artillery assault failed, the house gave the British a focal point to regroup, rally and reenter the battle. Maj. Marjoribanks then attacked the American flank in the clearing before the house before he was mortally wounded. According to Stewart, the Americans "gave way in all quarters, leaving behind them two brass six pounders and upwards of two hundred killed on the field of action, and sixty prisoners, amongst whom was Colonel Washington, and from every information, about eight hundred wounded..." According to
Otho Williams, some plundering of the British camp occurred, while an attack on the British left by Lee's cavalry failed. At this point, Greene ordered a retreat with all of the wounded. Greene's army was then able to march back to Burdell's Plantation in
column formation, with a cavalry
picket covering the orderly retreat. According to Greene, "Nothing but the brick house and their strong position at Eutaw's, hindered the remains of the British army from falling into our hands." ==Casualties==
