Prompted by Tiermats thread in the Pub re quoted from a film about WW1, one scene I often recall came to mind. From "For King and Country" about a court martial (Dirk Bogarde as Counsel, Tom Courtenay as the accused). The platoon mates of Courtenay's character, in a parody of the justice meted out to "deserters", decide to court martial a rat. To obtain the "accused" they beat the corpse of a horse with a spade, until the rats run out of its entrails.
