Pretty Cool. While the German need for weather information is well known ( we rounded up their stations in Greenland early in the war) what is really fascinating is what happened to the U-537 afterwards. She was sunk by a US submarine in the Java Sea!
"2nd patrol
U-537 sailed from Lorient on 25 March 1944 and traveled around Africa, and then crossed the Indian Ocean to Batavia, which she reached on 2 August after a voyage of 131 days.
3rd patrol
U-537 left Batavia for Soerabaja on 1 October 1944, and began her third and final patrol on 9 November. On that day she was spotted and sunk with all hands — 58 officers and men — in the Java Sea, at position 7°13′S 115°17′E, by torpedoes from USS Flounder (SS-251)"
I never knew we fought the Germans in the Pacific! So Blutarski from Animal House might have been onto something when described the Germans attacking us at Pearl Harbor.
