When the sergeant had finally got his rounds on target and I had commended to him a thorough review of the mortar manual, I climbed down the ladder and into the courtyard just in time to rendezvous with a small German shell which exploded a few yards away, raising a cloud of dust and sending me rolling with a small fragment lodged in the sitzplatz. When I opened my eyes, there was my bug-eyed sergeant hanging out the window of the belfry calling to his radio operator, "Joe, I think the Krauts got the old man in the tail."
