In April 1780, the Royal Fusiliers took part in the capture of Charleston. Once Charleston fell, the regiment helped garrison the city. Three companies were sent to Ninety-Six to assist with the training of Loyalist militia companies. An 80-man detachment also sent to Camden, South Carolina to help build that town's defences. The detachments were recalled to Charleston for refitting in late August 1780. They were then mounted and sent to join Charles Cornwallis's Army as it advanced towards Charlotte, North Carolina in early September 1780. The 7th, mounted on horses, along with two regiments of Loyalist militia, cleared the region north of Georgetown, South Carolina of partisans while en route. The Royal Fusiliers turned the horses over to Lieutenant Colonel Banastre Tarleton's British Legion upon uniting with Cornwallis in late September and then served as the Army's rearguard.
