The Upkeep mine was at last working and 617 Squadron had worked up to a level of skill that was unmatched amongst the Bomber Command units. The waters of the Ruhr dams had reached their peak and the moon was waxing gibbous towards being full. At last, all the preparation and training was going to be put to the test and the Dambusters raid was on!
At last… Upkeep had proved itself capable of being successfully dropped.

This is part three of a quadrilogy of stories about the Dambuster’s raid on the great dams of the Ruhr valley by No 617 Squadron. Wallis faced an uphill struggle to convince the Air Ministry that his idea of bouncing a huge mine across the surface of the reservoirs, over torpedo nets and right up to the dam walls was feasible. When finally given the go ahead he only had a few months to complete testing and then build a successful weapon. In the meantime, a new Lancaster squadron had to be formed and trained. This is a remarkable story of genius and tenacity in equal parts.

A man renown for his genius as a designer and inventor, Barnes Wallis turned his mind to helping Britain to win the Second World War by creating weapons that could defeat the industrial might of Germany. From his ten ton bomb Tall Boy to the bouncing bomb Upkeep, his remarkable talent ran from designing Airships to supersonic aircraft. This is his story.
