Description Lieutenant Alastair Mitchell, RCNR, had two loves - HMCS Dartmouth and Second Officer Linda Halley, WRCNS. He had to choose, but he couldn't. Then, on a cold, overcast November night off Bell Island, Newfoundland, the enemy made the choice for him. Whether called Sea Wolves or Raiders of the Deep, Nazi U-boats prowled the waters around Newfoundland.and some never left. Now Iron Coffins, they lie forgotten, rusting on the seabed along with their victims. The debris of war, they remain broken remnants of mankind's greatest conflict.
