On March 1st, 1945, he led “C” Company in a 500-yard attack across muddy terrain soaked by recent rain and snow, through barbed wire and enemy automatic weapons fire. After being slightly wounded by shell fragments in the head, he personally destroyed one enemy machine gun position with a hand grenade, and led the men of C company on to a second German line of resistance when he was wounded for the second time in the hip. He struggled to his feet and led his men forward where the Essex Scottish overran the enemy positions with rifle butts, bayonets and knives in close hand-to-hand combat. While consolidating the Canadian position against German counterattacks and on his 6th trip from a neighbouring unit bringing ammunition and grenades to his company, which had been depleted to about 25% of its usual strength or 40 men, Tilston was wounded for the 3rd time in the leg. He was found almost unconscious in a shell hole and refused medical attention while he organized his men for defence against German counter-attacks, emphasized the necessity of holding the position at all cost, and ordered his one remaining officer to take command. For conspicuous gallantry and steadfast determination in the face of battle, Tilston was awarded the Victoria Cross.
