Nigger died on 16 May 1943, the day of the "Dam Busters" raid, when he was hit by a car. He was buried at midnight as Gibson was leading the raid. The dog's name was used as a single codeword whose transmission conveyed that the Möhne Dam had been breached. In the film, the dog was portrayed in several scenes; his name and the codeword were mentioned several times. Some of these scenes were sampled in the film "Pink Floyd – The Wall" (1982).
