A new book about the Dambuster raid of 1943 in which many Australians took part.

Operation Chastise, the destruction of the Mohne and Eder dams in north-west Germany by the RAF's 617 Squadron on the night of 16/17 May 1943, was an epic that has passed into Britain's national legend.

Max Hastings grew up embracing the story, the classic 1955 movie and the memory of Guy Gibson, the 24-year-old wing-commander who led the raid. In the 21st Century, however, he urges that we should see the dambusters in much more complex shades. The aircrew's heroism was entirely real, as was the brilliance of Barnes Wallis, inventor of the ‘bouncing bombs'. But commanders who promised their young fliers that success could shorten the war fantasised as ruthlessly as they did about the entire bomber offensive. Some 1,400 civilians perished in the biblical floods that swept through the Mohne valley, more than half of them Russian and Polish women, slave labourers.
