On 21 March 1918 the Germans opened their Spring Offensive with 6000 guns. Hone's company halted the German's first infantry assault, capturing 25 German prisoners. Hone was awarded the Military Cross (MC) for his actions when the Germans attempted to enfilade the British lines, becoming severely wounded in the process. He was repatriated to England, and by the end of the war had been promoted to a captain. The day after the Armistice he married Elizabeth Matthews (b. 1894/5), with whom he later had two children, a son and daughter.
