The following morning, Mosby dispatched about 100 Rangers to escort the three wagons full of plunder back to Fauquier. He also dispatched Rangers Fount Bettie and Harry Heaton to report to Early, who was camped near Antietam Creek, with the message that Mosby's command would coordinate with his. Mosby then led his Rangers back to Point of Rocks to continue his raid into Maryland. The actions of the Rangers, however had not gone unnoticed in Washington and after learning of the raid, Maj. Gen. Henry Halleck dispatched the 8th Illinois Cavalry from Washington to Point of Rocks. When the Rangers arrived at the banks of the Potomac they found the 8th Illinois holding the village. A 90-minute firefight across the river ensued, in which the 8th Illinois claimed to kill one and wound two rangers while suffering no casualties themselves (Mosby made no record of any casualties), before Mosby broke off the attack and headed south towards Leesburg. The 8th Illinois were soon dispatched from Point of Rocks to Monocacy Junction, where Union Maj. Gen. Lew Wallace was assembling a rag-tag force to oppose Early's drive on Washington, and along with the Loudoun Rangers, would fight in the Battle of Frederick and the Battle of Monocacy.
