 A larger force of 79 Vickers Wellingtons would attack later, while the fighters were meant to be refuelling.The operation did not work as expected, with 90 Squadron's Fortresses being unopposed, with the German defenders concentrating on the Hampdens and Wellingtons, shooting down two and ten respectively.Small scale attacks continued, with four Fortresses attacking the German "pocket battleship" at Oslo harbour on 8 September, losing two of their number to German fighters.
