Once out of sight, Morgan and his men marched secretly through the woods to occupy the breastworks they had constructed on the south bank of the creek. The unsuspecting British arrived at the bridge and discovered the sabotage. While they halted to consider their options, Morgan began the Battle of Conjocta Creek by blowing a whistle to signal his soldiers, who fired a devastating volley. The British sought cover on the north bank and fired back, but the American troops remained protected behind their breastworks. The British attempted an assault on the breastworks, and the Americans allowed them to approach closely before again directing withering rifle fire into the British ranks. The British then attempted a flanking maneuver, which the Americans also repulsed. Unable to proceed past the Conjocta, the British retreated back to Canada. The Americans lost two killed and eight wounded, while the British sustained twelve killed and twenty-one wounded.
