US Army mortar team in action.

But the Germans are full of surprises. Before night, my company is pinned to a hillside. The krauts, who usually choose elevations for defensive stands, have fooled us in this instance. They have dug in by a dry stream bed at the base of the slope. Trees, cut and arranged in haphazard crisscross patterns, completely conceal their positions. They let us move over the hilltop, and then tear into our ranks with rifle and machine-gun fire. Mist gathers in the lowland, further hindering visibility. Crawling over the slope on our bellies, we try to pry out the enemy locations. But the camouflage is perfect. There is but one thing to do. I borrow a walkie-talkie radio and start maneuvering a patrol down the hill.
