The submarine had a maximum surface speed of 17.7 knots (32.8 km/h; 20.4 mph) and a maximum submerged speed of 7.6 knots (14.1 km/h; 8.7 mph).
Service history
After her commissioning, U-405 joined the
Patrol history
Of her eight war patrols, only on the sixth did U-405 sink any ships.[4] On 28 February 1943, south-west of Iceland, she sank the 7,176 GRT American liberty ship SS Wade Hampton. A straggler from Convoy HX 227, Wade Hampton was en route to Murmansk from New York, carrying 8,000 tons of general cargo as well as two PT boats (RPT-1 and RPT-3).[5]
Nine days later, on 9 March 1943, U-405 sank the 4,665 GRT Norwegian ship Bonneville which was en route from New York to Liverpool as part of Convoy SC 121, and carrying 7,196 tons of general cargo, explosives and the tank landing craft HMS LCT-2341 as deck cargo.[6]
After this success, U-405's seventh war patrol began badly, when at 19.24 hours on 4 May 1943, only two days out of Saint-Nazaire, the boat was attacked in the Bay of Biscay by a British Halifax GR.II Series IA bomber of 502 Squadron, RAF Coastal Command. The aircraft dropped three bombs, causing an oil leak that could not be repaired, prompting the captain to abort the patrol on 12 May. While returning home, on 18 May, northwest of Cape Finisterre, U-405 was bombed again, this time by an Australian Sunderland patrol bomber of 10 Squadron, although she escaped without any damage.[2]
Sinking
On the 23rd day of her eighth and final patrol, 1 November 1943, U-405 was engaged by the destroyer
Normally, in a surface engagement the superior armament and greater
At this point, about 35 of the German crew of 49 had been killed or lost overboard. Borie had been badly damaged and was moving at a reduced speed, while the submarine was still capable of maneuvering at a similar speed. U-405's tighter turning radius effectively prevented Borie from bringing her superior firepower to bear; Hopman did a masterful job of maneuvering his badly damaged boat with his remaining crew.[7] Borie shut-off her searchlight, her crew hoping that U-405 would attempt to escape and provide a better target for her guns. The submarine did indeed attempt to speed away, and Borie switched her searchlight back on and turned to bring her guns and a depth charge thrower to bear. The submarine was bracketed by shallow-set depth charges and struck by a 4-inch shell, and came to a stop. Borie's crew observed about 14 sailors signalling their surrender and abandoning ship in yellow rubber rafts. Hutchins gave the order to cease fire; several of them were apparently wounded, being loaded into the rafts on stretchers by their shipmates.
The last to leave the stricken ship was wearing an officer's cap. U-405 sank slowly by the stern at 0257. She was seen to explode underwater, probably from scuttling charges set by the last officer to leave.[8] Hutchins reported later:
"When the submarine sank, there was a yell that went up from all hands — it probably could be heard in Berlin. The men were clasping each other and patting each other on the back, and all during the action, there were times when it was actually comical to observe the situation, particularly with the submarine pinned underneath … heretofore their one dream had been to catch a submarine, depth charge him, bring him to the surface and then to sink him with gunfire, this particular action more than justified their hopes."[8]
The survivors were observed firing Very star-shells: Borie's crew believed this to be a distress signal, and maneuvered in an attempt to recover them from their rubber rafts, as they approached to 50-60 yards off the port bow. But as it turned out, the Germans were signalling another surfaced U-boat, which answered with a star-shell of her own.
A Borie lookout reported a torpedo passing close by from that U-boat, Borie had no choice but to protect herself by sailing away. She was forced to sail through U-405's rafts as she turned away from the other U-boat, but the men on the rafts were observed firing another Very flare as Borie steamed away in a radical zigzag pattern. No German survivors were ever recovered by either side; all 49 crewmen were lost.
Borie lost three officers and 27 crew members, and was too badly damaged by the collision to be towed to port. The next day, her crew was ordered to abandon ship and she was sunk by USS Barry.[9]
Wolfpacks
U-405 took part in nine wolfpacks, namely:
- Wrangel (11 – 18 March 1942)
- Strauchritter (2 – 5 May 1942)
- Nebelkönig (27 July – 14 August 1942)
- Trägertod (12 – 18 September 1942)
- Boreas (19 November – 9 December 1942)
- Neptun (18 February – 3 March 1943)
- Westmark (6 – 11 March 1943)
- Siegfried (25 – 27 October 1943)
- Siegfried 1 (27 – 30 October 1943)
