Charles Algernon Fryatt (2 December 1872 – 27 July 1916) was a British mariner who was executed by the Germans for attempting to ram a U-boat in 1915. When his ship, the SS Brussels, was captured off the Netherlands in 1916, he was court-martialled and sentenced to death although he was a civilian non-combatant. International outrage followed his execution near Bruges, Belgium.
