Andy, I think HMS Belmont was one of the destroyers Churchill arranged on Lend Lease. HMS Belmont (H46) was a British Navy Town Class Destroyer. She was built as the USS Satterlee (DD190) in Newport News Shipbuilding and Dry Dock Co, Virginia, USA. On the 31st January 1942 in the North Atlantic SE of Halifax, Nova Scotia whilst escorting a Canadian Troop Convoy NA2 to the UK she was torpedoed and sunk by German submarine U-82. All the crew perished.
As you say, a remarkable story, and I'll raise a glass tonight in memory of that brave crew.
