You catch up with your platoon just as the creeping barrage stops. Your men rush the German second line trench - and it's mostly empty. After a quick barrage of hand grenades, the few surviving Germans surrender. Patrols go down into the bunkers and soon group after group of Germans come up, with their hands up.

Your orders are to stay put. A British reserve battalion will "leapfrog" over your position and continue the attack on the German Number 3 and 4 trenches. While they do that, you are to repair the trench defenses and prepare for a possible German counter-attack.

Your men, however, are eager to keep going. They've taken two trenches in just a few hours, there is plenty of daylight left, and the Germans aren't putting up much of a fight. They want to take that third trench. What should you do?
