Service life was enlivened by various scrapes and escapades, including an occasion when Fiennes and another officer procured a very lively, squirming piglet, covered it with tank grease and slipped it into the crowded ballroom of the army's Staff College, Camberley. On another occasion, offended by the construction of an ugly concrete dam built by 20th Century Fox for the production of the film "Doctor Dolittle" in the Wiltshire village of Castle Combe, reputedly the prettiest village in England, Fiennes planned to demolish the dam. He used explosives which he later claimed to have accumulated from leftovers on training exercises. Using skills from a recently completed training course on evading search dogs by night, he escaped capture, but he and a guilty colleague were both subsequently traced. After a court case, Fiennes had to pay a large fine and he and his co-conspirator were discharged from the SAS. Fiennes was initially posted to another cavalry regiment but was subsequently permitted to return to the Royal Scots Greys.
