As we were coming down the duckboard track after being relieved Jerry started to put over a barrage.
I pawed the mud with my right in order to find the duckboard.
At some 'posts' there was nothing better to sit on than the muddy 'fire-step' or at best half a duckboard or an old bomb box.
I stamped on the duckboard and kicked the sides of the trench and jerked my rifle up and down just to keep myself awake.
It was about a mile from the line down a "beautiful" duckboard track.
