Puggy Stephenson, Vice-Admiral and Commodore of the Western Isles, was best-known simply as The Terror of Tobermory. But Puggy was a terror for a purpose. Tobermory and the Western Isles were a theatre in the Battle of the Atlantic and Gilbert Stephenson knew well the responsibility he faced in training up raw and inexperienced crews into a trained and effective ship's company. His methods were directly responsible for the sinking of over 130 U-boats and the shooting down of 40 enemy aircraft. Behind his ferocity lay a marvellous sense of humour and a deep humanity. This is the story of his life.
