Crawford took part in several important battles during the remainder of the war, commanding a battery of "Fowey"s guns that had been landed to defend Savannah during its siege. The besieging forces were eventually repulsed and for his good service there, Crawford was mentioned in the despatches written by Captain Henry, and the commander of the land forces, General Augustine Prévost. "Fowey" then moved to support the Siege of Charleston, which ended in the capitulation of the city to the British. Following this success, Captain Henry was again transferred, taking over command of the newly captured , with orders to take her back to Britain carrying despatches. Crawford again accompanied Henry, still with the rank of acting-lieutenant.
