My Feldwebel cursed. He said this smoke was a marker flare, fired by one of the enemy tanks to mark our position. This meant that they had called for an air attack on us. He leaned out of the hatch and shouted to the infantry to extinguish the blue flare, but they were slow to respond, and other blue shells or flares burst close to us then. So this was how the Shermans did battle! They fired smoke shells to mark us out for the air force to attack.
