German submarine U-455 was a Type VIIC U-boat built for Nazi Germany's Kriegsmarine for service during World War II. She was laid down on 3 September 1940, launched on 21 June 1941 and commissioned on 21 August 1941 with Kapitänleutnant Hans-Henrich Giessler in command of a crew of 51.
1st, 2nd and 3rd patrols
U-455 's operational career began when she left Kiel on 15 January 1942. Her first patrol took her to Iceland via Stavanger and Bergen in Norway. She returned to Bergen, empty-handed, on 28 February 1942.
The boat's second patrol was similarly unproductive, leaving Bergen on 21 March 1942 and arriving in St. Nazaire in occupied France on the 30th. She would continue to use this port for most of the rest of her career.
Her third foray was better; on 3 May 1942, she sank the British Workman off Cape Race, Newfoundland, followed by the Geo H. Jones on 11 June northeast of the Azores. Having departed St. Nazaire on 16 April 1942, she returned on 16 June, having spent 62 days at sea.
4th and 5th patrols
Her 4th patrol was even longer, it took her as far as the US Georgia coast, southeast of Savannah. She returned to St. Nazaire on 28 October 1942, having commenced the voyage on 22 August, a total of 68 days.
Her fifth patrol started on 24 November 1942; she scoured large swathes of the Atlantic, all to no avail.
6th, 7th, 8th and 9th patrols
Success continued to elude her; the only excitement on her sixth patrol was when a crewman was injured by one of the boat's own AA guns.
Things became even more serious on her eighth patrol. With a new captain, Kplt. Hans-Martin Scheibe, who had assumed command on 22 November 1942, U-455, along with U-264 and U-422, were caught on the surface on 4 October 1943 while re-fuelling from U-460 by TBF Avengers from USS Card. The smaller boats escaped, but U-460 was sunk.
10th patrol and loss
On 6 April 1944, U-455 was lost with all hands. No explanation exists for her loss, but it is believed that she possibly struck a German mine. However, there is no confirmation. Her last transmission was on 2 April 1944, four days prior to her disappearance, when she radioed-in while on patrol off the coast of Algiers.
