Information on this section
We have a total of 5,102 patrols by 862 U-boats listed here. Of those 3584 were war patrols.
This database consists of 129,059 entries of which 114,115 have full daily positions (lat, long). They are linked from all U-boat patrols, search pages and elsewhere where they can be of assistance. The positions are always shown as a "map" link where you can find details on the patrol in question.
Special thanks to the Libary of Contemporary History in Stuttgart for their invaluable help on this project.
