Menace from the Deep

The platoon are on guard duty on a derelict pier, which they have reached by boat but, thanks to Pike's clumsiness, the boat has floated away, carrying their food. Hodges rows out in a children's boat to tell them to 'put that light out' and falls into the sea. Dispensary chocolate turns out to be a cardboard display but worse is to come when a floating mine appears.
