 When she arrived she was quickly ordered out to patrol the Bay of Biscay because it was feared that the German battleships "Scharnhorst" and "Gneisenau", and the heavy cruiser "Prinz Eugen", all lying at Brest, were imminently to come out.They did not do so during "Ursula"'s patrol (not emerging until 22 February 1942) and Hezlet handed "Ursula" over for refit at Chatham on 12 January 1942.In late March 1942 Hezlet was given command of HMS "Trident", the boat in which he had been First Lieutenant at the beginning of the war, with Ian McGeoch as his first lieutenant.
