Hello everybody and dear specialists.During the two world wars,did the german Uboots attack with succes some US boats ?
Yes, of course. Initially, they were very successful until the Brits with their sonar and centrimetric radar defeated them. It was a close-run thing but in the end, the Germans were thoroughly defeated.

Thank you very much. But how many US comercial boats (food,animals etc...) were destroyed by the Uboots in 14-18 and 39-45 ?
