The 1st Battalion was assigned to the 4th Infantry Brigade in the 2nd Canadian Infantry Division. The battalion saw combat for the first time at Dieppe on August 19, 1942. Of the 582 soldiers who landed that morning, only 102 (18 percent) were not among the casualties: 197 killed, 174 captured and 194 wounded (including 85 also captured). The Dieppe survivors suffered great physical trauma and psychological distress as a result of the battle and the loss of so many of their friends and comrades in a battle that lasted only about eight hours.
