Hurwitz was awarded the Military Medal for extraordinary heroism and leadership in his first major action in France, on the afternoon of August 4, 1944, during the epic Battle for the Falaise Road. Reginald Roy of the Canadian War Museum described it as "one of the most swiftly successful troop actions by Canadian tanks in the entire Normandy Campaign". Moe was then second-in-command of #4 Troop, #3 Squadron of the 22nd Canadian Armoured Regiment (Canadian Grenadier Guards). Although missing one of its usual four Sherman tanks, and without infantry support, the group of 15 Grenadiers assaulted the flank of the main enemy defensive position in front of the village of Cintheaux. In little over ten minutes, they destroyed 11 German anti-tank guns, including six 88's, and forced two others to withdraw. The Grenadiers also killed at least 15 Germans, captured 31 others, and opened a kilometer-wide gap in the German front line, against a loss of only one Guardsman killed and one wounded.
