Bill's prime Cause Celebre has resulted in his being included in the Guinness Book of Records as having made the deepest unaided ascent from a sunken submarine. He has other claims worthy of recognition, he was among those officers and men who trained many of the crews who joined the Twelfth Submarine Flotilla during WW2. This Flotilla consisted of X Craft and Two Man Chariots. It was based at Port Bannantyne on the Isle of Bute. The HQ was known as HMS Varbel.
The incredible true story of the search for and discovery of the USS Grunion. Discovered in 2006 after a decades-long, high-risk search by the Abele brothers whose father commanded the submarine and met his untimely death aboard it.
One question remained: what sank the USS Grunion? Was it a round from a Japanese ship, a catastrophic mechanical failure, or something elseone of the sub's own torpedoes? For almost half the war, submarine skippers' complaints about the MK 14 torpedo's dangerous flaws were ignored by naval brass, who sent the subs out with the defective weapon.
Fatal Dive is the first book that documents the entire saga of the ship and its crew and provides compelling evidence that the Grunion was a victim of The Great Torpedo Scandal of 1941-43. Fatal Dive finally lays to rest one of World War II’s greatest mysteries.
