Eames did not even realize that his head was above the parapet. The hardest thing to teach a soldier is not to expose himself. Officers keep iterating warnings and then forget to practise what they preach. That morning a soldier had been shot through the heart and arm sideways behind the trench. He had lain down unnoticed for a nap in the sun, it was supposed. When he awoke, presumably he sat up and yawned and Herr Schmidt, from some platform in a tree, had a bloody reward for his patience.

"There are three or four sharpshooters and a fat old Boche professor in spectacles, who moves a machine-gun up and down for a bluff," said a soldier, and another corrected him:
