Eisbär (English: Polar Bear) was a wolfpack of German U-boats that operated from 23 to 29 August 1942 in World War II. This pack was assembled to operate in the South Atlantic off Cape Town which was considered to be virgin waters. Some of the most experienced U-boat commanders available such as Harald Gelhaus, Werner Hartenstein and Carl Emmermann were included. They shadowed the Freetown, Sierra Leone to Liverpool Convoy SL-119, and sank only one ship for a total of 5,941 gross register tons (GRT).
