Although not under attack, the Union troops in Summerville began moving toward Gauley Bridge early in the morning on September 11. Lightburn believed his entire force would need to retreat, and their probable destination was Point Pleasant on the Ohio River at the mouth of the Kanawha River. Lightburn's Second Brigade, commanded by Colonel Samuel Gilbert, had been at various positions north of the Kanawha and New rivers. During Siber's morning fighting, Gilbert positioned artillery on the north side of the Kanawha River at Montgomery Ferry. The artillery and supporting forces totaled to less than 600 men, and they protected Siber's supply wagons as they ferried across the river. Siber's wagons joined Lightburn's main force and continued moving west down the north side of the Kanawha River, while Siber's men moved in the same direction down the south side of the river. Most of the afternoon's fighting at Montgomery Ferry consisted of Gilbert's artillery against Confederate artillery. Although Gilbert's men set the ferry boat on fire and continued their retreat west, Confederate soldiers swam across the river and extinguished the blaze. The Confederate pursuit was continued on both sides of the river. More skirmishes occurred on that day at Loup Creek, Armstrong's Creek, Miller's Ferry, Gauley Ferry, and near Cannelton.
