Experts and witnesses believe that a wreck located near Vigo (Northwest Spain) last August could be, by 'its relief and dimensions', a German submarine sunk in 1943

During the bloodiest phase of the second world war, feared Nazi submarine clandestinely resorted to the Galician coast to intensify their tenacious battle to sink or even destroy any Allied ship that defied crossing the Atlantic.
The ports of Vigo and Ferrol were vital for this target of Hitler to isolate and suffocate Britain and resistance in Europe.

They needed them as basis for merchant, fuel tankers, food and supply German boats for the U-boots submarines, what allowed to lengthen their hunting by not having to return to their bases in France or Germany.

To avoid suspicion, supplies were moved at night and, for example, between November and December 1941 different submarines, as U-574 and U-434, fill their bodegas in the same way.
In the case of the latter two, his target was to prepare them to destroy an Allied convoy from Gibraltar. However, Fortune did not accompany them. U-434 was badly damaged during the attack and was captured by the British, who interrogated the crew. The secret was exposed to recognize the Germans that had refueled in «Bernard», code name for the Vigo port.

The Allied intelligence services stepped up its surveillance in Galician lands, which soon became a real nest of spies. Protests in London and Washington forced the Franco regime to prevent refueling in port and, therefore, the German motherships were transformed to stock on the highsea but as close as possible of the rias and Galician coast.

If we are to believe those who argue that a german submarine would be located, more predictable is that it was the U-566, which just set sail from France to the Mediterranean on her 15th patrol, was seen on 24 October 1943 by the British bomber "Wellington" launched six charges that caused him major problems that prevented him from submerging. Her captain, Hans Hornkohl, ordered drilled it and the crew jumped into several pneumatic rafts. Subsequently, 49 officers and sailors were rescued by the fishing ship FINA that, ironically, moved them to Vigo where they were handed over to the German consul who immediately negotiated his return to France. Officially, the U-566 sank to 41 ° 12'n - 09 ° 31'W, perhaps soon will know whether this information is accurate or not.
