From Diary of the American Revolution, Vol II. Compiled by Frank Moore and published in 1859.
The evacuation of Camden animated the friends of Congress, and daily increased their numbers; while the British posts fell in quick succession. The day after the evacuation, the garrison of Orangeburgh, consisting of seventy British militia and twelve regulars, surrendered to Sumpter. Marion and Lee, after the capture of Fort Watson, crossed the Santee and moved up to Fort Motte, which lies above the fort, on the south side of the Congaree, where they arrived on the 8th of May. The British had built their works round Mrs. Motte’s dwelling-house, which occasioned her moving to a neighboring hut. She was informed that firing the house was the easiest mode of reducing the garrison; upon that she presented the besiegers with a quiver of African arrows, to be employed in the service. Skewers armed with combustible materials were also used, and with more effect. Success soon crowned these experiments, and her joy was inexpressible upon finding that the reduction of the post had been expedited, though at the expense of her property. The firing of her house compelled the garrison, of one hundred and sixty-five men, to surrender at discretion on the 12th, after a brave defence.1
