Once we got over the continent the weather started to get bad and worsened as we got closer to the target. Near the Dutch-German border a NF suprised us and blew out the Starboard Wing Flap, holed the Starboard rudder and put the tail turret out of action … we never saw him. I began violent evasive flying and we got away. The clouds were heavy and low over the target and it was hard to see the target markers … we dove low over target, dropped our load over the city center and pulled back up. Flak was close to us but no hits. The flight home was uneventful.
