German submarines landed men in Québec and Labrador twice during the war. On the night of 8-9 Nov 1942 the spy Werner Janowski came ashore from U-518 near New Carlisle, Qué, and was almost immediately captured, later becoming an RCMP double agent. On 22 and 23 Oct 1943 the crew of U-537 landed an automatic weather station at Martin Bay, 32 km S of Cape Chidley, Labrador. The station transmitted data for about 3 months. Although sighted by casual visitors, it was not properly identified until July 1981 and now displayed at the Canadian War Museum..
There seems to be a related story on a possible... "WW2 NAZI RAID ON THE ISLE OF WIGHT – ADRIAN SEARLE" ...just (21st December 2016) posted here: WW2 Nazi Raid on The Isle of Wight – Adrian Searle "Adrian Searle is a journalist and author who has written extensively on a range of historical topics. Born and raised on the Isle of Wight, he returned to the island in 1984 to edit a local newspaper and has worked in a freelance capacity since 1989. A keen student of railway history and operation, he has written widely on several related aspects."
I firmly believe there was a German landing on Britain in WW2. There was even a film about it showing how they were repulsed by Angela Lansbury, David Tomlinson, a little magic and the local Home Guard:
Just because a film was made about the subject doesn't mean it was true. Even more sceptical if Lord Haw Haw made reference to it. Believe him and believe Nazi propaganda.
