German submarine U-161 was a

Hans-Ludwig Witt (Knight's Cross
).

The U-boat's service began with training as part of the 4th U-boat Flotilla. She then moved to the 10th flotilla on 1 January 1942 for operations. She sank 12 ships, totalling 60,107 gross register tons (GRT); one warship of 1,130 tons and damaged five others, for 35,672 GRT. She also damaged one warship (5,450 tons) and caused one merchant vessel to be declared a total loss (3,305 GRT).

She was sunk by an American aircraft on 27 September 1943.

Design

supercharged four-stroke, nine-cylinder diesel engines producing a total of 4,400 metric horsepower (3,240 kW; 4,340 shp) for use while surfaced, two Siemens-Schuckert 2 GU 345/34 double-acting electric motors producing a total of 1,000 metric horsepower (740 kW; 990 shp) for use while submerged. She had two shafts and two 1.92 m (6 ft) propellers. The boat was capable of operating at depths of up to 230 metres (750 ft).[2]

The submarine had a maximum surface speed of 18.3 knots (33.9 km/h; 21.1 mph) and a maximum submerged speed of 7.3 knots (13.5 km/h; 8.4 mph).

2 cm (0.79 in) C/30 anti-aircraft gun. The boat had a complement of forty-eight.[2]

Service history

First and second patrols

The submarine's first patrol took her from

Shetland Islands. She arrived at Lorient
, in occupied France, on 3 May. She would be based at this Atlantic port for the rest of her career.

U-161's second sortie proved to be successful, damaging British Consul and Mokihana on 19 February 1942 while the ships rode at anchor in the Gulf of Paria off Port of Spain, Trinidad.[3] She went on to sink ships such as Circe Shell, Lihue the petrol tanker Uniwaleco off St Vincent.

Then, daringly, she made her way at night through the narrow passage into

U.S. Army mine planter General John P. Story transferred to the United States Lighthouse Service at no cost in 1922,[5]
) was sunk by gunfire from U-161 approximately 150 miles south of Port-au-Prince, Haiti. The entire crew of Acacia abandoned ship before she sank and all were rescued unscathed. She was the only U.S. tender sunk by enemy action during the war in the Caribbean.

Third patrol

The boat's third patrol took her past the

Cape Verde Islands, to the Brazilian coast north of Fortaleza. She then followed that coastline north until she reached the Caribbean. On 16 June 1942 she stopped the sailing ship Neuva Altagracia with gunfire and sank the vessel with scuttling charges. She also attacked San Pablo while the ship was being unloaded in Puerto Limón, Costa Rica
on 3 July. Although the ship sank, she was raised with the intention of repair; but she was declared a total loss and sunk as a target on 25 September.

She crossed the Atlantic in an easterly direction, but turned about and returned to the Caribbean. Having commenced the return leg to France, she encountered Fairport 500 nmi (930 km; 580 mi) north of St. Thomas, Virgin Islands on 16 July and sank her. The boat returned to Lorient on 7 August.

Fourth patrol

Her fourth foray was to west Africa. This patrol was her longest-113 days. She damaged the light cruiser

Takoradi
in Ghana on 8 November.

Fifth patrol

The boat's fifth patrol involved another Atlantic crossing and sinking a second sailing ship, Angelus, north of Bermuda, again with gunfire. Ten survivors abandoned the vessel; only two were still alive when their lifeboat was discovered.

Sixth patrol and loss

Aerial attack on U-161 by a PBM-Mariner of VP-74 on 27 September 1943.

The U-boat departed Lorient for the last time on 8 August 1943. She rendezvoused with the

PBM Mariner aircraft of VP-74
in the South Atlantic.
