'Iltis' (i) was a U-boat wolfpack operation in the Atlantic Ocean off the coast of North-West Africa against the SL.119 convoy (25/29 August 1942).
The wolfpack comprised U-107, U-214, U-406 and U-566, and for the loss of none of its own number sank two ships (14,085 tons).
U-214, which was on passage to the south, located the SL.119 convoy, and the wolfpack’s other three boats were vectored to the convoy’s reported position, as too were the favourably situated four boats of the 'Eisbär' (i) wolfpack (U-68, U-156, U-172 and U-504) which were on passage to South Africa.
On 26 August Korvettenkapitän Werner Hartenstein’s U-156 sank the 7,062-ton British Clan Macwhirter, a straggler from the SL.119 convoy, and after this the 'Eisbär' (i) wolfpack continued its original sortie on the orders of the German naval staff.
On 28 August Oberleutnant Gerhard Remus’s U-566 sank the 5,661-ton British City of Cardiff and 8,424-ton Dutch Zuiderkerk of the SL.119 convoy, but was then depth-charged and damaged, and U-107 was driven off.
On 29 August the other boats had to break off their efforts.
