The Eder Breaks by Ivan Berryman.  
The success of the attack on the Möhne dam on the night of 16th/17th May 1943 meant that the remaining three 617 Sqn Lancasters of the First Wave could turn their attention to the Eder, some twelve minutes flying time away. Wing Commander Guy Gibson first called in Flight Lieutenant D J Shannon, flying AJ-L (ED929G) to make the initial run, but he had great difficulty achieving the correct height and approach, so Gibson now ordered Squadron Leader H E Maudslay in AJ-Z (ED937G) to make his run. Again, the aircraft struggled to find the correct height and direction, so Shannon was again brought in, AJ-L finally releasing its Upkeep on the third attempt. The bomb bounced twice before exploding with no visible effect on the dam. Now Maudslay made another attempt, but released his bomb too late. The mine bounced off of the dam wall and exploded in mid air right behind AJ-Z, the Lancaster limping away, damaged, from the scene, only to be shot down on the way home with the loss of all crew. Finally, Pilot Officer Les Knight was called in for one final attempt. AJ-N (ED912G) released its Upkeep perfectly, the mine bouncing three times before striking the dam slightly to the south. In the ensuing explosion, the dam was seen to shake visibly before the masonry began to crumble and a massive breach appeared. With the Möhne and Eder dams both destroyed and the Sorpe demonstrated to be equally vulnerable, Operation Chastise had been a remarkable success and will stand forever as one of the most heroic and audacious attacks in the history of aerial warfare.
