On 30 April 1940, at 14:15, as Maillé Brézé was anchored at the Tail of the Bank off Greenock, a torpedo tube misfunctioned and launched an armed torpedo on the deck, setting fire to the fuel tanks and the forward magazine, which however did not explode. She was raised in 1954 and broken up by 1956. The wreck currently visible opposite Greenock (and thus not to be confused with the Maillé Brézé) is that of the MV Captayannis which sank in 1974.
