Wolfpack Hecht

Hecht (English: "Pike") was the name of two "wolfpacks" of German U-boats that operated during World War II.

First wolfpack "Hecht'
The first wolfpack code-named Hecht, comprising three U-boats, operated east of Iceland from 27 January to 4 February 1942. During this period one Allied convoy passed through Hecht's patrol area, Arctic convoy PQ 9/10, comprising ten merchant ships bound for the Soviet Union. It departed Reykjavík on 1 February and was undetected, arriving without incident at Murmansk on 10 February. After this Hecht was disbanded, with U-352 and U-455 continuing to the North Atlantic, while U-435 remained on station for four more days before heading north to join patrol group Umbau in the Barents Sea.

Second wolfpack "Hecht'
The second operated in the North Atlantic from 8 May to 18 June 1942. During this period Hecht successfully attacked three west-bound convoys, and sank 14 ships for a total of. After forming in the Atlantic on 8 May the Hecht boats headed west, sighting slow convoy ON 92 south of Iceland. They attacked over the next three days and sank seven ships without loss.

On 20 May Hecht boats sighted slow convoy ON 94 east of the Grand Banks, but lost it in fog.

On 31 May ON 96 was sighted south of Cape Farewell, but this was also lost in worsening weather.

On 8 June convoy ON 100 was sighted five days out from the UK; an attack developed which sank five ships and an escort vessel over four days, again without loss.

On 12 June convoy ON 102 was sighted, but attacks over three days and nights brought little success; one ship was sunk, but two U-boats were damaged so severely they had to return to base.

At this point BdU brought Hecht’s patrol to an end.
