Hi Platon
I took my informations from literature sources.

CAP HADID:
Following Arndt, Deutsche Sperrbrecher 1914-1945, 1st print, S.326) Cap Hadid acted as a stand-in for the U-boat supply ship (Z-schiff) Python. When Python left port, Cap Hadid had to take up her position as if Python were still there. This action was repeated several times.
After being damaged by limpet attack in Dec 1942 the ship was rebuilt and put to service as Sperrbrecher 122 (2nd Spbr flottilla) on 10. Febr. 1943 in Nantes.

SPERRBRECHER 14:
BOCKENHEIM had already been heavily damaged on 22. June 1942 by mine explosion off Royan and allegedly got further damages by the attack of 12. Dec 1942 ("Frankton"). It is documented that BOCKENHEIM was put out of service on 12. Dec 1942 at 11.00 Uhr in Bordeaux. She was no longer operational and scuttled on 25. Aug 1944 as blockship in the Gironde mouth. In 1947 salved and wrecked!
