Major General John Sullivan's Maryland division and Brigadier General Thomas Conway's Pennsylvania Brigade, Wayne's troops forced back the British. Eager to avenge their defeat at Paoli, Wayne's soldiers charged forward with fixed bayonets and overran the light infantry's camp. The light infantry rallied on the 5th Foot and 55th Foot, but the three British units were soon forced to withdraw. When the British army commander General Sir William Howe appeared on the scene he was startled to see his crack light infantry fleeing before the American advance. He yelled, "For shame, Light Infantry! I never saw you retreat before. Form! Form! It is only a scouting party". After nearly being cut down by a blast of grape shot, Howe and his staff quickly rode off. The 2nd Pennsylvania Brigade soon struck a picket of the 46th Foot and swept it before them. Soon Wayne's men became anxious because fighting at the Chew House erupted several hundred yards in their rear. Isolated in the fog, Wayne ordered an about-face and his two brigades began to move back toward the noise of battle. The 2nd Brigade, now on the division's right, blundered into part of Major General Adam Stephen's division moving forward. In a tragic friendly fire incident, Stephen's men opened fire and the Pennsylvanians returned fire. Wayne's soldiers, fired on by their friends and confused by the fog, panicked and took to their heels. They finally rallied from the battlefield. The riflemen with Morgan returned from the north and rejoined the regiment late in fall 1777. When the regiment went into winter quarters at Valley Forge, Bayard was lieutenant colonel and Frederick Vernon was major. The 8th Pennsylvania was assigned to the Western Department on 19 May 1778. The unit added a ninth company by absorbing Captain Samuel Morehead's Independent Company on 1 July 1778. The regiment was involved in Brigadier General Lachlan McIntosh's expedition to Ohio in November 1778. In January 1779, Captain John Clark and 15 soldiers of the 8th had just left Fort Laurens to travel to Fort McIntosh when they were ambushed by 17 Mingo Indians led by American Loyalist Simon Girty. Clark lost two killed, four wounded, and one captured before he and the survivors fought their way back to the fort. The fort held out against an Indian siege until relieved in March 1779, but McIntosh's plans for a continued advance to Fort Detroit were
