Shepard missed the Second Battle of the Piave River in April 1918, being on leave in England (where he was invested with his MC by King George V at Buckingham Palace) and where he was attending a gunnery course. He was back in Italy with his battery for the victory at Vittorio Veneto. After the Armistice of Villa Giusti in November 1918, Shepard was promoted to acting major in command of the battery, and given the duty of administering captured enemy guns. Demobilisation began at Christmas 1918 and 105th Siege Battery was disbanded in March 1919.
