The platoon are soon put to the test, and are handed what was clearly a quickly-made meal. As the exercise continues, Mainwaring falls down a hole, finds a secret tunnel and discovers it leads to Rodrigues' HQ. Later that night having been missing all afternoon, he returns to take the platoon through the tunnel and ends up in the stores. Walker is impressed, and it isn't long before the HQ is captured. On the train home, Mainwaring is relieved to find himself in his mens good graces again, though laments that he felt the platoon deserved a more tangible reward. Walker then reveals that he is fully laden with food as whilst the others were dealing with Rodrigues, he was cleaning out the stores.
