These photos of U-410 and her crew were generously made available by Nicolas Bracco of Argentina.  They originally belonged to Oberleutnant zur See Gerhard Peters, who was IIWO and later IWO on U-410.  He later commanded U-1198. 
        U-410 made two patrols under her first Commander, Kapitänleutnant Kurt Sturm.  Oberleutnant zur See Horst Arno Fenski assumed command on 5 February 1943 and after a patrol in the Atlantic he took the boat to the Mediterranean and made 4 more patrols before the boat was heavily damaged in an air raid in Toulon in March 1944.  Fenski and much of her crew took over U-371 and made one patrol during which the boat was sunk by US forces.
