Promoted to the rank of Lance Sergeant on October 10, 1944.
Service records report date of death October 12, 1944 but this is probably a write up mistake. L/Sgt. MacKay most likely was killed in action on October 11, 1944.
That afternoon, 'C' Squadron made an attack on the position where the German 20mm had been the night before. They used our flame throwers and the carrier section. Although the attack was successful, we lost L/Sgt. "Bill" MacKay and his buddy. Both were killed when they attempted to take some prisoners. Bill was a good friend of mine, we joined up the same day, my number was D/3515 and Bill's number was D/3555. Bill's buddy that day was a Sengalise French soldier. He had been picked up in France and given a Canadian uniform. He followed Bill very closely all the time and died beside him. Sgt. J.F. McGowan.
