The trenches roof is low and so you keep your head down to avoid having your brains plastered over the muddy wall behind you and your eye hanging out by a tendon, luckily, the Germans seem to have decided that for now you will live and the machine gun fire that used to rattle through the landscape slows down slightly. Eventually you reach a taller part and stand up a little more before sitting down on the fire step next to some of your British brethren.
