HMHS Llandovery Castle, built in 1914 in Glasgow as RMS Llandovery Castle for the Union-Castle Line, was a Canadian hospital ship on a voyage from Halifax, Nova Scotia to Liverpool, England that was torpedoed off southern Ireland on 27 June 1918 with the loss of 234 lives. In terms of the number of dead, the sinking was the most significant Canadian naval disaster of WW1. The incident became renowned as one of the war’s worst atrocities. After the war, the case of the Llandovery Castle was one of six British cases presented at the Leipzig trials.
