Operation Chastise in 1943 was a British RAF raid in which No. 617 Squadron attacked German dams in the Ruhr Valley, including the Möhne and Eder dams, using “bouncing bombs” designed by Barnes Wallis. The operation involved the United Kingdom striking targets in Nazi Germany and caused major flooding and industrial disruption, though with significant RAF losses and civilian casualties.
