After a fairly extensive skirmish at Wiboo Swamp, Brig. Gen. Francis Marion had retired towards down the Santee Road and deployed his men at Mount Hope Swamp where he destroyed the bridge over the stream there. Lt. Col. John Watson again advanced and Brig. Gen. Marion’s riflemen under Lt. Col. Hugh Horry and Capt. William McCottry (might've been Robert McCottry) attempted to dispute the passage there. But Lt. Col. Watson cleared the way with grapeshot from his cannon and had his men wade through the stream. Brig. Gen. Marion withdrew in the direction of Georgetown expecting Lt. Col. Watson to follow.

Lt. Col. Watson, however, pursued him a short distance but then turned and headed in the direction of Kingstree, one of the main focal points of rebel activity in the region. Desiring then to cut him off, Brig. Gen. Marion sent ahead Maj. John James with 70 men, including 30 of McCottry’s riflemen, to seize the Lower Bridge at the Black River and on the road Lt. Col. Watson was taking to Kingstree.

Maj. James, taking a shortcut, reached the bridge before Lt. Col. Watson, and removing some planks from the bridge, set his men in position. Brig. Gen. Marion, meanwhile, also came up with the main body prior to Lt. Col. Watson’s arrival. When Lt. Col. Watson did approach he attempted to bring his cannon to bear on Brig. Gen. Marion’s men, but due to enemy sharpshooters and the unusual terrain there was unable to do so, losing some men in the process.

Lt. Col. Watson then tried crossing at a ford not far distant. Yet when he reached the spot he was again kept back by the riflemen. By the end of the day, Lt. Col. Watson retreated to Witherspoon's Plantation where he camped.

The next day (the 15th) Brig. Gen. Marion’s men under Captains Daniel Conyers and McCottry sniped at Lt. Col. Watson’s camp from concealed positions. Lt. Col. Watson then removed his force that same day to Blakely’s Plantation. Although not having as many trees and foliage as there were around Witherspoon’s Plantation, Brig. Gen. Marion’s sharpshooters followed him there and continued their sniping.

Despite his casualties and the difficult situation, Lt. Col. Watson remained at Blakely’s until March 28th.
