On the night of 16/17 May 1943, Operation Chastise, the famous attack on German dams, was carried out by No. 617 Squadron of RAF Bomber Command, later immortalized as the “Dam Busters.”
The Möhne and Eder dams were breached, causing catastrophic flooding in the Ruhr and Eder valleys, while the Sorpe Dam sustained only minor damage. 2 hydroelectric power stations were destroyed and several others damaged, along with factories, bridges, railways, and mines. An estimated 1,600 civilians were killed in the flooding, including roughly 1,000 Soviet forced laborers. The RAF lost 8 of the 19 aircraft dispatched, with 53 aircrew killed and 3 captured.
Do you remember that show Man, Moment, Machine? They did an episode on the Dam Busters mission, but in theirs, the machine was the Vickers Type 464 bouncing bomb, codenamed “Upkeep,” designed specifically for the raid, and the man was its creator, Barnes Wallis.
We would suggest two additions.
In our version, the machine would also include the Avro Lancaster B.III Special, a modified version of the Lancaster created specifically to carry Upkeep. The aircraft had an empty weight of 35,240 lbs and a maximum takeoff weight of 60,000 lbs. Upkeep was carried partially exposed beneath the fuselage on a special mounting system rather than fully enclosed in the bomb bay. Before release, an electric motor spun the cylindrical bomb backward at high speed, allowing it to skip across the water, strike the dam wall, sink alongside it, and detonate underwater against the structure.
And as for the man, you would also have to include Wing Commander Guy Penrose Gibson, DSO and Bar, DFC and Bar, commander of 617 Squadron, codenamed for the mission as “Squadron X.” For his leadership in the planning, training, and execution of the raid, Gibson was awarded the Victoria Cross by King George VI, making him one of the most highly decorated British servicemen of the war. Gibson completed 172 combat missions before being KIA at the age of 26 during a bombing mission to Bremen, Germany, in Sept 1944.
