Karl-Friederich Merten
Commander U-68
Member #23-1984
Kapitän Merten was born 15 August 1908 in
Posen and he was in the Naval Class 1926. His one and only U-Boat command
was U-68, but he was highly successful with that boat, sinking some 29
ships with a total of 180,869 gross tons.
When he was just a Leutnant zur See, he was Gunnery Officer aboard the cruiser KÖNIGSBERG
then was posted to T-157. Later he was commanding officer of the
escort vessel F-7 and then became Cadet Training Officer aboard the old coal
burner SCHLESWIG-HOLSTEIN but he wanted service in the U-Bootwaffe.
Early on in 1940 he volunteered for the U-Bootwaffe and later sailed aboard U-38
under HEINRICH LIEBE (1670-1990) as Kommandantenschüler (Commander in
Training). upon completing his training, he commissioned the Type IX-C
long range U-68 at her AG Weser building yards in Bremen on 11 February
1941. He commanded this boat on five very successful war patrols.
One of his most notable accomplishments was commanding the rescue effort that
brought many U-Boats together in the South Atlantic to rescue the survivors of
the raiders PYTHON and ATLANTIS after their crews scuttled the
ships. Under Merten's command, several U-Boats literally towed the
lifeboats all the way back to the French ports.
Merten later was posted to command the 26th U-Bootflottille at Pillau and
lateron, he commanded the 24th U-Bootflottille at Memel. He was
instrumental in the safe evacuation of some 50,000 civilian inhabitants and
6,000 Hitler Youth out of Memel as the Red Army was closing in.
After the war, he evaded the conquering Allies until October 1948 when he was
arrested and brought before the Frimaire Tribunal in France. The French
hatred of the Germans notwithstanding, Merten was released in March of 1949.

Many years after the war when the book and movie "das
Boot" was released, KURT BABERG teamed up with Captain KARL-FRIEDERICH
MERTEN to write a book entitled:
"Nein! So was
das nicht!" which
means "No!
It was not this way!"
The subtitle was 'eine anti-Buchheim schrift' or 'an anti-Buchheim
writing'. In this book, they dispute much of what Buchheim wrote in this
book. Most U-Bootfahrer did not like what Buchheim wrote in this book and
they were furious about what Buchheim wrote in his next book, which contained a
great many insults against Großadmiral Karl Dönitz.
Captain Merten was with us for our 2nd Sharkhunters Convention when he joined us
in Hamburg and spent the day riding the harbor tour with our group, signing
autographs etc. Captain Merten also sent us some combat films taken of his
boat and from his boat, which we converted into videotape H-8 for our
Members. In a letter to Sharkhunters in the late 1980's, Captain Merten
said that he would help Sharkhunters to his utmost because he wanted us to keep
the history of his comrades alive and historically correct.
