Combat at the edge of the Antarctic

Who fought in or near Antarctic waters?

Allied convoy forces and German surface raiders carried the war into the Southern Ocean, including attacks connected with merchant and whaling traffic.

The far south did not host a conventional continental campaign, but naval war reached the Southern Ocean. British, French, and other Allied forces protected traffic moving through those waters. German surface raiders such as Thor operated far south and threatened merchant and whaling activity, including the Norwegian whaling fleet. The answer broadens the geography of the Second World War beyond its familiar Atlantic and Pacific centres.
