What was the objective of "Operation Chastise" carried out by the British in 1943 during World War II?

Question

Which ship was sunk in World War II on 17 June 1940 in the course of evacuating British nationals and troops, with the loss of an estimated more than 4,000 men, women and children?

Answer 1

To bomb German dams, vital to industry
"Operation Chastise" was carried out by the 617 Squadron of the Royal Air Force, which came to be known as The Dambusters, by launching bouncing bombs invented by Sir Barnes Wallis to skip over the surface of the river until they met the dam and exploded. Two of the three dams targetted were breached, leading to serious flooding although not much else; nearly half of the bombers which took part were lost, but Allied morale jumped.
