Weddigen was formed in November 1943 off the coast of Portugal, to intercept convoys sailing to and from Gibraltar, Mediterranean and South Atlantic. It was composed of U-boats from the disbanded patrol group Schill, with reinforcements from the North Atlantic and from bases in occupied France.
Weddigen originally numbered seventeen U-boats, though two had been destroyed in recent actions, and two others had to withdraw with damage. On 22 November the thirteen U-boats remaining formed a patrol line west of Portugal to await warning of an Allied convoy.
On 23 November one of the Weddigen boats, U-648, fell in with the frigate HMS Blackwood, of 4th Escort Group accompanying KMS 30 and was destroyed. On 25 November U-600 also fell in with MKS 30, and was attacked by Blackwood and Bazely, and was destroyed by them.
On 27 November the Weddigen boats intercepted convoy SL 140/MKS 31, and attacked it over the next five days, though without success. On 29 November U-86 was destroyed by aircraft from the carrier USS Bogue, while on 28th U-238 and U-764 had been attacked and damaged, also by aircraft from Bogue.
On 7 December Weddigen was disbanded, a number of U-boats returning to base, while others formed a cadre of a new patrol group, code-named Borkum.
