Trench warfare on the Western Front during World War One.
British officer standing in trench fiddling with small bomb or grenade. He strikes the bomb against a block strapped to his wrist, like striking a match, and throws it. He turns and looks at camera.
A catapult is attached to edge of trench. We see a soldier pull the sling back, attaches it to a hook and puts small bomb in it. L/S of large structure in distance. Catapult is released.
Seems to take some time, the bomb missing the structure in distance, a cloud of smoke rises beyond it. Soldier reaches out of trench to set catapult again. The soldier smokes a cigarette during the entire bomb firing procedure.
