There were some unusual junior officers on the front. One was Lieutenant Ed Gesner of the 4th Infantry Division. He knew survival tricks that he taught his platoon, such as how to create a foxhole in frozen ground: he shot eight rounds into the same spot, dug out the loose dirt with his trench knife, placed a half stick of TNT in the hole, lit the fuse, ran, hit the dirt, got up, ran back, and dug with his trench shovel. Within minutes a habitable foxhole.
The junior officers coming over from the States were another matter. Pink cheeked youth, they were bewildered by everything around them.
