Ferdinand the Submariner Bull

The October, 2009 Naval History magazine has an article by British submariner Rear Admiral Sir David Scott, recounting his experiences patrolling the Mediterannean in World War II, a theater where British submarine mortality rates approached 50%. He mentions the importance of humor, no matter how desperate the circumstances and relates:

Such were the puerile comforts in the face of imminent annihiliation. We even displayed a sense of humor when we painted emblems on the subs. In one case, for example, we avoided the obvious sharks with huge teeth and avenging devils and instead emblazoned our boat with an image of The Story of Ferdinand, who preferred to stay home and sniff the flowers rather than face the combat of the bullring. In any case, we knew that, like Ferdinand, we were the muscular best of the breed.
