"Read about this a few years ago:
In 1943 a group of German sailors on a U-Boat emplaced a weather station on the Canadian coast (Labrador) so the Germans could more accurately predict the weather for military operations (since weather in the Northern hemisphere generally moves west-to-east.) The weather station was marked with fake signs indicating that it was a Canadian military facility and for unauthorized personnel to keep out.
The weather station was eventually discovered by the Canadians.......In 1977."
