Type I-A German U-Boat

Actually, this is a misnomer because the first of a U-Boat type did not have the “A” after it. The Type I was merely the Type I, and only two were made because this just was not a very good submarine. The crews did not like their unpredictable handling – they would surface or dive almost on their own. U-25 and U-26 were the only two Type I German U-Boats ever made. The Type I was a twin shaft diesel-electric sea-going submarine with relatively long range and it was based on the GUR that Germany had previously built for the Turkish Navy. The Type I carried fourteen torpedoes.

U-25 saw action during the Spanish Civil War but not much is recorded about that time.

With the outbreak of World War II, U-25 was attached to the 1st U-Bootflottille and later to the 2nd U-Bootflottille.  She operated in the North Atlantic – over October and November of 1939 she operated in the Bay of Biscay; over January and February of 1940 she patrolled off the Spanish and Portuguese coasts; then off Norway in April 1940.

U-25 took on fuel from the tanker THALIA in Cadiz, Spain then began operations west of Gibraltar in February 1940.

*  U-25 fired at this tanker, surfaced and watched the torpedo hit and detonate. The ship following the tanker rammed U-25 which took Beduhn’s attention away from the tanker but he saw the tanker stopped dead in the water. When he was able to look again for this target nearly an hour later it was gone, so he assumed a sinking. No confirmation.

On 21 June 1940, U-25 damaged the 10,000 ton French tanker ARAGAS.

The 16 October 1939 issue of LIFE Magazine featured a cover photo of U-25 taken through an open porthole of a ship that U-25 stopped.  With the U-Boat alongside, the ship’s papers were checked and after finding no contraband, she was allowed to proceed unharmed.

 was attached to the 2nd U-Bootflottille and operated in the English Channel during September 1939 and laid mines off Portland, England over 8-10 September 1939.  She successfully broke through the Straits of Gibraltar on 8 November 1939 then she broke out of the Mediterranean through Gibraltar on 18 November 1939.  She was to lay mines at Gibraltar but that plan was aborted.  U-26 then patrolled one time in the North Atlantic and had two patrols off the Norwegian coast and one more in the North Atlantic where she was sunk.

Deepest thanks to our friends at the U-Bootskameradschaft Kiel for allowing us to bring their sacred book containing the names of all 28,863 U-Bootfahrer who were lost in action during World War II here to the USA where we carefully copied all the names of the fallen and list them here on our site.  Ours is the only website in the world that lists all these names.

Many thanks to our good friend and Sharkhunters Member since 1987 GEORG HÖGEL (240-LIFE-1987)for all the conning tower emblems used in our monthly KTB Magazine and also here on the pages of our website. GEORG was Funkmaat (radioman) aboard U-30, the first boat into combat, the first to sink a ship (the liner ATHENIA) and the first into an occupied French port.  When that Skipper (Lemp) took command of U-110, GEORG was one of the former crew to transfer to the new boat under Lemp.  After the war, he was Professor of Art at a major German university.
