Ship's cat
Convoy was the ship's cat aboard HMS Hermione.  He was named "Convoy" because he often went with the ship on convoy escort duties (where the ship would sail with a group of other ships for protection).  Like the ship's sailors, Convoy was listed in the ship's book, and given a full kit, including a tiny hammock where he would sleep. He was killed along with 87 of his crew mates when Hermione was torpedoed and sunk on 16 June 1942 by German submarine U-205.
