The 617 Squadron – the incredible story of Operation Chastise

Mohne dam after the attack

Guy Gibson’s aircraft was first to attack the Möhne at 12.28am, followed by Hopgood. Hopgood’s aircraft was hit by flak as it made its low-level run and was then caught in the blast of its own bomb, crashing shortly afterwards. Three crew members successfully abandoned the aircraft, but only two survived.

Gibson then bravely flew his aircraft across the dam to draw the flak away from Martin’s run. Martin dropped the third bomb despite his aircraft being damaged, but his attack was a success. Young then made a successful run, and Maltby followed shortly after, which resulted in the dam was breached.

Gibson, with Young accompanying, led Shannon, Maudslay and Knight to the Eder, but five aircraft had to drop their bombs before it was breached. Maudsley, Knight and Shannon pressed on towards target two, with Shannon’s plane making six separate unsuccessful runs before taking a break. Maudslay then made an attempt, but his bomb struck the top of the dam and the resulting blast severely damaged his aircraft. Shannon made another run and successfully dropped his bomb. Finally, Knight’s craft had a stab, dropped the bomb and the dam was breached.

Formation two consisted of five aircraft, piloted by Flt Lt Joe McCarthy, Flt Lt Les Munro, P/O Vernon Byers, P/O Geoff Rice and Flt Lt Norman Barlow. They were to attack the Sorpe, but weren’t as successful as the other formations. The approach proved more difficult than first thought with a church spire affecting the initial plans, and only McCarthy made it to the dam. His plane was joined later by two from formation three, but this dam wasn’t breached. Thick fog hampered efforts and although damage was caused, it wasn’t enough to render the dam useless.

Formation No. 3 was a reserve of sorts, consisting of five aircraft piloted by Flight Sergeant Cyril Anderson, Flt Sgt Bill Townsend, Flt Sgt Ken Brown, P/O Warner Ottley and P/O Lewis Burpee. The took off two hours later on 17 May, with a brief to either to bomb the main dams or to attack three smaller secondary target dams.

Of the 133 aircrew that took part, 53 men were killed. A further three became prisoners of war after one aircraft crashed. On the ground, 1,600 civilians were killed in the resulting flooding, 1000 of which were said to be Soviet prisoners forced into labour. The raid was a success, although the impact on industrial production was limited, it gave a significant morale boost to the people of Britain.

The surviving members of 617 Squadron were rightly received as heroes, and Guy Gibson was awarded the Victoria Cross for his actions during the raid. The operation established 617 Squadron as a specialist precision bombing unit, experimenting with new bomb sights and target marking techniques.

75 years on the legend and legacy lives on, as it always should. Sometimes I hear criticism that our fans have taken the name of the 617 squadron, but I see it as a mark of respect. I do hope each and every one of them reads this, those that don’t already know, so they fully understand exactly who they are representing and why we are so proud of having such a brave and courageous group of men attached to our city.

Below is a list of the 133 men who took part in those daring raids, with links to for more information. Today, 75 years on, why not pick one of these brave men and share his biography on your own social media pages. Pick the one closest to your name alphabetically maybe, or if you’ve seen one posted already chose one of the more obscure names. Whatever you do, please share one. That way, from pilots to wireless operators, we will remember them all.

  1. Thanks for this article Gary. Really important that people hear about the bravery of this group of men. My grandfather joined 617 shortly after the raid and got to know some of those named very well. He was involved in many other events with the squadron including the bombing of the battleship Tirpitz and also the controversial raids over cities like Dresden and Cologne. I am sure that all had a big impact on him and his fellow airmen. He passed away back in 1979 but I still have very fond memories of him. He was very proud of serving in the RAF. Did not like football though!

  2. Good that you have said about commemorate not celebrate here. I am probably on my own on this but I feel it is time to
    Leave the war behind in terms of a celebration. When I see Lincoln City memes with Lancasters on it, it is invoking that we “won” and there is a parallel with us winning. Firstly it makes the war effort and the sacrifice feel trite, secondly are we not past all that “we won the war” stuff? My abiding memory at the Germany v England game in South Africa will forever be the camera lingering on two lads dressed in RAF uniform down beat at 4-1 and the German fans chuckling at the big screen behind us.
    Be proud of the brave service men and women. But for me I think it should be left well away from the club. That is not how I would think it should be commemorated. I wouldn’t expect a US team to have Enola Gay emblazoned on their team shirt in pride at their plane ending the war with Japan. There is solemn respect for the act and loss of life.

    Sure I am in a minority and I am not telling people what to do and nor would I expect them to listen. Just airing my thought about it as someone who wouldn’t be here had RAF Scampton not existed in 1944 when the US Air Force came over… and a lincoln fan

    Ps fabulous piece as ever
