On May 16, 1943, 19 Lancaster bomber crews gathered at a remote RAF station in Lincolnshire for a mission of extraordinary daring – a night-time raid on three heavily defended dams deep in Germany’s industrial heartland.
The dams were heavily fortified and needed the innovative bouncing bomb – which bounced on the water over torpedo nets and sank before detonating.
To succeed, the raiders would have to fly across occupied Europe under heavy fire and then drop their bombs with awesome precision from a mere 60ft above the water.
19 Lancaster Bomber crews armed with Bouncing Bombs set off to attack several dams in Germany on May 16, 1943
The Eder Dam, pictured, was destroyed as part of Operation Chastise on the early hours of the morning on May 17, 1943
The Mohne and Eder Dams in the industrial heart of Germany were attacked and breached by mines dropped from specially modified Lancasters of No. 617 Squadron.
The Sorpe dam was was also attacked by by two aircraft and damaged.
A fourth dam, the Ennepe was reported as being attacked by a single aircraft (O-Orange), but with no damage.
Up to 1,600 people were estimated to have been killed by floodwaters and eight of the 19 aircraft dispatched failed to return with the loss of 53 aircrew and 3 taken prisoner of war.
Wg Cdr Guy Gibson, Officer Commanding No. 617 Sqn, is awarded the VC for his part in leading the attack.
The raid, orchestrated by Guy Gibson and the RAF’s 617 ‘Dambuster’ Squadron, was seen as a major victory for the British, and Wing Commander Gibson is recognised as one of the war’s most revered heroes.
Their success was immortalised in the classic 1955 film The Dambusters, its thrilling theme tune and gung-ho script evoking the best of British derring-do.
Eight of the bomber crews were lost while a further three were forced to turn back. Of the 133 men sent out, 53 were killed and three were taken prisoner by the Nazis
