Obtaining weather data was vital for military operations in Northwestern Europe during World War II. In an effort to secure this data, the German Navy and Air Force secretly established manned weather stations in East Greenland, Svalbard, and Franz Josef Land. War North of 80 is the personal story of Wilhelm Dege, the leader of the last weather station, code-named "Operation Haudegen." With a detailed introduction, Barr's translation offers Engish-speaking readers a rare glimpse into the Germans' account of weather activities during World War II in the Arctic. An epilogue written by Dege's son offers insight into the various fates of the expedition members who worked alongside his father.
