Skirmish, Lt. Col. Henry Lee vs. British suppliers to Orangeburgh.

On August 3rd, the British seized control of McCord’s Ferry on the Congaree River. Lt. Col. Henry Lee had been ordered by Maj. Gen. Nathanael Greene to strike at the enemy’s lines of communications from Orangeburgh to Charlestown. McCord’s Ferry was along that line.

Lt. Col. Lee circled around the British camp at McCord’s Ferry with sixty men and crossed the river. His cavalry dispersed thirty-two wagons with an escort of 300 men within sight of the garrison at Orangeburgh. The lead elements of the escort fell back, but Lt. Col. Lee’s men had to break off their attack when the main body of the British refused to yield. Lt. Col. Lee was able to capture twenty of the enemy.
