Alysse (formerly HMS Alyssum) was one of the nine Flower-class corvettes lent by the Royal Navy to the Free French Naval Forces.

Construction

Alysse was built by George Brown & Co.

War service

Originally built as HMS Alyssum by the British Royal Navy, she was loaned to the Free French Navy upon completion on 17 June 1941.

Shortly after midnight on 9 February 1942 while escorting convoy ON-60, Alysse was torpedoed by the German submarine U-654. The torpedo struck Alysse on the port side in the forward part of the ship causing her to settle by the bow. The surviving crew were rescued by HMCS Hepatica and HMCS Moose Jaw; 36 crew members were lost. Hepatica then attempted to tow Alysse but after 30 minutes the tow parted. A further attempt was made to tow her to port later that day but after 18 hours Alysse foundered and sank at 6°34N/44°10W.
