The U-boat bases
This new and exiting section of uboat.net will contain detailed and extensive information on the German U-boat bases of World War Two when completed.
Missing right now are pages on bases in Germany, Italy, Greece, the Far East.
Bases in Germany
This set of pages is dedicated to the numerous bases utilized by U-boat in Germany before and during the war. This is of course far from complete and only 2 bases have their pages installed so far.
Kiel (1st, 3rd, 5th, 6th, 7th and 19th), Hamburg (31st & 32nd).
Bases in France
From late 1940 to late 1944 the bases in France were the busiest bases servicing the most famous U-boats. 8 combat flotillas were stationed in France. A map showing the location of the bases is also available.
Lorient (2nd and 10th), Brest (1st and 9th), Saint Nazaire (7th and 6th), La Rochelle (3rd) and Bordeaux (12th). Toulon in the Mediterranean was established in 1943.
Bases in Norway
Norway was invaded by German forces in April 1940 and after several famous battles and fierce fighting finally fell to Germany in the spring. U-boats began to operate from its many favorable ports as early as April 1940 and did so until early May 1945.
3 U-boat flotillas were established there, the 11th at Bergen in May 1942, the 13th at Trondheim in June 1943 and the 14th at Narvik in Dec 1944.
