The Unsinkable Mary Lehane

Somewhere on the ocean floor off Algeria in the Mediterranean Sea lies a once-graceful passenger liner that served as a troopship to Allied soldiers during World War II.

She met her doom on a moonlit night on December 21, 1942, torpedoed by a German U-boat.

On board the RMS Strathallan were more than 4,000 British and American troops, 872 crew and 250 members of the Queen Alexandra Imperial Military Nursing Service.
