The Plan Is Born

From the early days of the Second World War (3rd September 1939) the brilliant, if eccentric, scientist and aircraft designer Barnes Wallis was considering ways to shorten the war. From the outset, the Mohne, Eder and Sorpe Dams in the Ruhr presented attractive yet daunting targets, providing hydro-electric power, industrial and domestic water and maintaining levels in canals which fed materiel between factory and war depot. Destroying such targets would reduce the enemy's capacity to wage war and such targets had been envisaged as important since war loomed in the late 1930s.

The massive Dams would be untouched by any bomb which RAF bomber aircraft of the day could carry. The water at the dam face acted as an effective cushion between the explosion and the dam wall, absorbing and dissipating most of the explosive force, and it was impossible to drop a big enough bomb accurately enough to cause a breach. Aerial torpedos were out; the Germans had stretched cable defences and booms across the water. The lakes being land-locked, attack by submarine was not possible.

After exhaustive research into bomb types and explosive effects, Wallis discovered that if he could make a bomb land up against the wall, the water cushioning acted in his favour, tamping in the explosion and directing enough blast to punch a hole. He smashed many model dams, and in early June 1942 destroyed a disused real one (the Nant-Y-Gro dam near Rhayader, in Wales) until he found the ideal size bomb. His problem was now one of placing the dropped bomb or mine accurately.

In July 2000 and againin May 2006 I visited the site of the destroyed dam, which is located in the picturesque Welsh hillside on the south bank of the reservoir which is readily accessed via the Visitor Centre at Rhayader, this being signposted from the town centre.  The entire reservoir area is a most beautiful series of hill walks and open to the public.  In fact, the handout describing the walks mentions the dam, which is clearly seen from the public path.  The actual dam is fenced off and to visit it in detail, permission should be obtained to cross into the tiny valley in which it sits.  (An added bonus is overflights by RAF aircraft on training operations.  Watch out for the Tornados and Jaguars streaking along the valleys and skylines.)

Directions : walk along the north shore and up to the large dam which overshadows the Visitor Centre.  Cross the river at the old pumping station bridge and make the steep climb up the south shore to the large dam itself and go through the gate at the top.  Rest here after the climb, and admire the magnificent view up the reservoir.  Continue along the south bank, with the reservoir to the immediate right, and follow this sometimes twisting footpath until it turns left and climbs up with a small valley to the left.  200 yards up this, as the little valley deepens, you will see the remains of the dam on the right.

On the photo descriptions, "left"” and "right"” are as viewed from the downstream or debris field side.

The right hand remaining shoulder of dam wall, some 15 feet high from the footings, and the water-level remains of the dam base, showing the debris field of large concrete chunks.

The hole blown in the dam is about 30 yards across, and whilst at the time of the explosion the dam was full, nowadays just a trickle of water runs though the gap and down the small valley.  Much debris is evident on the downstream side, which drops away quite steeply to the reservoir.  Paul Brickhill in "The Dam Busters" describes the hole as 15 feet across and 12 feet deep, but he is notoriously incorrect on fine detail like this.  However, it is fair to comment that further collapses may have occurred or been induced over the 58 intervening years, widening the size of the gap stated by Brickhill.

 

 

 

 

The left hand shoulder from the high valley side upstream of it.  This wall is also some 15 feet from footings to top level, and about 30 inches wide at the top, quite enough to walk along (I did).  The crack produced by the explosion is 4 to 6 inches wide and as can be seen here, runs from the true shoulder of the dam to a point about 3/5 of the way down the waterside wall.

This isn't a very good photo of me. The weather was plain bloody awful and we'd ridden about 60 miles in the rain then walked up to the dam site in the rain.

 

 

 

 

 

 

 

 

 

 

 

 

Large photograph (left), showing the footings with water running through, right hand shoulder of the remaining dam wall quite visible and the concrete compensating basin in the immediate foreground. 

The left hand wall remains can't be seen from this angle.  I did my best to get an accurate then-and-now match, but found that if I matched the angle exactly, overgrowth prevented anything like a decent view; so I stepped (slid!) down the very steep bank about 12 feet, accounting for the different perspective..

 

 

 

 

 

 

 

 

Compare my May 2006 photo above with the "official" monochrome one (left) taken at the height of the explosion, June 1942.  The compensating basin is clearly seen, as is the intact dam wall, as the water plume is driven skywards by the blast.  Fractions of a second later, the wall collapsed.

Using an extremely large testing tank and various shape and weight golf ball sized projectiles, he conducted many experiments, catapulting the missiles into the water at varying speeds and angles until he could predict the length and height of each bounce.

This caused the model mine to skip over the surface of the water, avoiding the boom defences, until it struck the dam face. Calculations showed that real drops would have to be carried out at a strictly controlled speed, and at the very low height of 150 feet. The mine was backspun before release and on impact crawled down the face of the dam to explode at a preset depth. It acquired the codename "Highball" for the scaled down anti-ship version and "Upkeep" for the full sized weapon.

Although a stress engineer and presented with many unfamiliar calculations and avenues of research, by 1942 he was ready to ask for aircraft and other resources. His idea seemed completely implausible to officialdom, and he was laughed out of many a Governmental office. By sheer persistence and doggedness, and helped by one or two sympathetic people, he obtained permission to build a scaled down version of the bomb and allowed to convert a Wellington bomber to drop it. (He had, incidentally, designed the Wellington.)

First trials with a half sized mine proved successful and he obtained filmed proof that the idea worked. But again the red tape was thick. Desperate, he persuaded Vickers' chief test pilot, Mutt Summers to get him an interview with Air Chief Marshal Sir Arthur T Harris, Commander-in-Chief of Bomber Command. Although Harris had previously described the idea as "Tripe of the wildest description ... nobody would object to the Highball enthusiasts being given one aeroplane and told to go away and play whilst we get on with the war", he trusted Summers and was cajoled into watching the films taken at the test drop and testing-tank. Afterwards Harris was non-committal, but about that time Churchill gave the project his backing and in early 1943 Wallis was given the official "go." With the need to attack the Dams in mid May when they were full, this left little time to complete the project.

Harris declined to withdraw an existing squadron for special training, and decided to form a new Squadron of expert aircrews. He assigned Air Vice Marshal the Hon. Ralph Cochrane, Officer Commanding No 5 (Bomber) Group, to see to it. Cochrane had earlier supported Wallis's case. "I've got a job for you, Cocky," Harris said, and explained. Cochrane asked if he had anyone in mind to command the Squadron. Harris said "Yes. Gibson." Cochrane agreed and sent for Wing Commander Guy P. Gibson, then O.C. No 106 Sqdn flying Lancasters from Syerston. Gibson had a long and satisfactory career as both a bomber and night fighter pilot, and had won the DSO and bar and the DFC and bar and was about to finish his third tour of operations. Sent for by Cochrane, and anticipating a long leave in Cornwall, he was astonished when Cochrane asked him "How do you feel about doing one more trip?"

Gibson said "Yes" and he was caught up in a mad whirlwind of picking his pilots and crew and the 1,001 details of forming a new Squadron. Given a free hand, he chose some pilots he thought were the best, many who he knew personally were very keen types and who would not baulk at the prospect of a dangerous operation. However many of the personnel were unknown to him and some were even on their first operation.

Guy Gibson's mother Leonora came from a well known shipping family in Porthleven, Cornwall and when staying there Gibson developed a love of the sea and sailing. In a visit to the harbour in June 2012 I was pleased to see a plaque in remembrance of Guy. This was placed in the church wall, overlooking the harbour.

(Divall and Wilson were later killed)

Returned to original unit after initial posting to 617 Sqdn: Sgt Lovell and crew (back to 57 Sqdn); F/S G Lanchester RCAF and crew, the latter because Gibson did not consider their navigator sufficiently skilled to handle what promised to be a demanding operation, and the crew would not be parted from him. Paul Brickhill in 'the Dam Busters' also describes a couple of the ground crew assigned to the new Squadron crews as "outrageous duds" and Gibson himself was equally scathing, taking pleasure in returning the two men to their previous unit.

Training, Security and More Problems

Equipped at first with borrowed and later with their own modified Lancasters, the new 617 Squadron commenced flying training from RAF Scampton, the station commanded by Group Captain Charles Whitworth. With everyone except Whitworth and Gibson unaware of the real target, crews were delighted to be sent on long low-level cross country flights; such were normally strictly forbidden. As proficiency improved, night flying training was added. This proved very hazardous and the answer was a training aid called "Two Stage Blue Day Night Flying" where the pilots wore blue goggles and the cockpits were sheathed in amber screens. This gave the effect of moonlight flying in broad daylight, yet the pilots could still see their instruments. It had been invented by two brothers, S/Ldrs Arthur and Charles Wood.

Security was extremely tight. 617 was supposed to be a normal Squadron; yet there were too many well decorated and experienced operational crews for this to go unnoticed. Gossip abounded, but the security held and although there were a couple of minor breaches, Gibson's astringent way of dealing with them stopped any further lapses. There seem to have been some inexplicable compromisations of security at higher levels, but these did not reach enemy ears. At Scampton, the other residents, 57 Squadron, were at first amused and then annoyed by 617's apparent lack of operational time. Called the armchair warriors once too often, the 617 officers replied with a comprehensive de-bagging session which claimed many a 57 Squadron victim.

Meanwhile, full sized mines built by Wallis had been dropped and failed to work, either breaking up on impact or refusing to perform properly. Strengthening the case was not the full solution, and Wallis buttonholed Gibson after a disastrous test drop at Chesil Beach. "I asked if you could drop the mine at 150 feet; can you do it at sixty feet?" Gibson shuddered. "That's very low," he said, aware that 60 feet was about half the wingspan of his Lancaster and at that speed and height a hiccough by the pilot could put the aircraft into the water. "But they've given me some crack crews so we'll give it a try."

Practice failed to make perfect. Even Spam Spafford, Gibson's hard-bitten bomb aimer, was shaken. "Christ," he said down the intercom as the Lancaster just missed the water on a training flight, "this is bloody dangerous." Eventually the technique of shining two fixed spotlights, one from the nose, one from the belly of the aircraft, proved simple and effective; the navigator leaned out into the Perspex cockpit blister and called directions whilst the pilot tweaked the Lancaster's height until the two beams were alongside in a figure-8 with the aircraft then steady at 60 feet. This technique had first been used in World War I.

Bomb-release accuracy was less than satisfactory until Wing Commander Dann, a sighting expert, showed Gibson a simple triangulated wooden bombsight with two nails at one end and a peephole at the other. Looking through the peephole as the aircraft approached the target, the bomb-aimer pressed the release button when twin towers on top of the dam were in line with the nails. Dummy towers were built on the Derwent Dam in Derbyshire and Gibson found that the sight worked immediately. It was so simple that individual bomb-aimers were able to make their own; some even used string attached to the bomb-aimer's Perspex. Held up to the eye and marked at the required position, it was equally effective. With the height and sighting problems beaten, it was just a matter of the flight-engineers jockeying the Lancaster's throttles to get the speed correct at 220 mph.

Normal navigation was a serious problem at ultra-low altitudes. Navigators made maps on rollers and drilled the bomb-aimers into giving precise pinpoints as the aircraft progressed. Hampered by the poor performance of the then standard H.F. voice radio, Gibson hounded his superiors until Cochrane produced VHF fighter radio-telephones, improving voice communications dramatically.

Despite changes to and tests with the weapon continuing until only days before the raid was planned to take place, many problems were overcome and on the night of Sunday May 16th 1943, 19 Lancasters took off for the Dams, in three waves; Gibson's flight to attack the Mohne and Eder, McCarthy's to attack the Sorpe, and a mobile reserve and diversionary force led by Townsend. A full moon lit the night sky, making normal operations impossible. An apparently bad omen was that Gibson's black Labrador, Nigger, had been run over and killed as the crews were being briefed for the operation. Gibson had given orders that Nigger was to be buried at midnight on the grass verge outside his office; he had the premonition that he and Nigger would be going into the ground at the same time. The car's driver, a doctor from Grantham, did actually stop.

(It's interesting to note that on some versions of the film, the name "Nigger" is either cut out or voice-overed. The prospect of adjusting history in the interests of Politically Correct Stupidity never ceases to amaze me. It is apparently PC to remind the Germans they lost the war but not PC to say the correct name of a dog. In this context, who could take offence? The editing required to eliminate the name of Gibson's dog also results in some important tracts of the film being lost.

Yet - in the far more recent film "Gangs Of New York" the n-word is used throughout, and in threatening and abusive circumstances, which are consistent with the storyline of the film. Ain't the world crazy?)

The outward trip was flown all the way at low level and claimed 'B' (Astell) who hit high tension cables and crashed at 0015, 5 km SSE of Borken; 'S' (Burpee) hit by flak and crashed at 0200 near Gilze-Rijen aerodrome, Holland; 'E' (Barlow) who crashed at 2350, 4 km ENE of Rees, also after hitting high tension cables; and 'K' (Byers) was brought down by flak at Texel. The Germans recovered Barlow's mine. All the crews were killed. Munro in "W" was hit by flak over Vlieland and his intercom and radio shot out; unable to communicate at all, he turned for home. Rice in "H", using his belly lights to fix his height over the Zuider Zee, only found out that the alignment had slipped when his Lancaster hit the water at over 200 mph, tearing out the mine. Dragging the Lancaster back into the air, he too had to go home.

The Mohne Dam was 900 yards long and 112 feet wide at its base. Gibson, giving instructions on the crystal-clear VHF radio telephones with which the squadron's aircraft had been fitted, grouped his remaining aircraft and made his bombing run, dropping the mine none too accurately and under strong flak opposition. Once the spray cleared, Hopgood attacked, but was hit by flak, causing the mine to overshoot the dam's parapet and explode directly beneath the Lancaster. "Poor old Hoppy," said a voice on the radio; only two members of the crew (Fraser and Burcher) escaped by parachute in the seconds before the aircraft crashed. Martin attacked next and this time Gibson flew alongside, helping to draw and disperse the enemy fire. Martin's Lancaster was hit in an empty fuel tank; his mine exploded successfully but the drop was inaccurate. The dam held. (Film buffs may care to note that the opening scenes of the attack are repeated almost word for word in the film Star Wars, as the rebel space fighters attack the Death Star. If you don't believe me, try this Youtube link.)

Gibson and Martin both drawing the defences, Young went in next and dropped his mine spot on the right place. Still there was no breach. Next was Maltby who also dropped accurately and as the spray cleared, a 100 yard hole was seen to open up in the dam wall, releasing 134 million tons of water. Shannon, squaring up for his approach, was told to abort, and Gibson sent the others home, taking his remaining aircraft on to the Eder and sending the code word "Nigger" by wireless to show that the Mohne was down.

The Eder, nestling in hills far deeper than anticipated, required the pilots to dive steeply and level out sharply at the start of the bombing run, then try to lose a great deal of accumulated speed. Only 5 or 6 seconds were available to do this. Shannon then Knight had great difficulty in losing enough speed at the end of the diving approach; afterwards it was necessary to pull up equally sharply to avoid the hills. The whole attack needed airmanship of the highest order. There were no defences; the Germans didn't think the Eder needed any.

Shannon made several runs but was not satisfied and did not bomb. He then asked for permission to reconnoitre. Gibson agreed and sent in Maudslay . He too made several abortive runs before he seemed to have lost enough height and speed, but he must have been going just a little too fast. The bomb overshot, exploding on the parapet with the Lancaster directly above. Gibson, appalled, called his friend. "Henry, Henry, hello Z Zebra, are you all right?" A faint voice replied, "I think so - stand by." Maudslay had been hit hours earlier on the way in over the Dutch coast, and several crew wounded, but he had pressed on. Gibson called again, but there was no reply. Critically damaged by the explosion, Maudslay turned the aircraft for home, but crashed at Emmerich after being engaged by light flak. The entire crew were killed.

Shannon, more confident, attacked and dropped his mine successfully. Knight attacked next and had the same problem as the others; it was very difficult to lose the speed incurred by the diving approach, and yet pull up at the far end of the lake. Shannon gave advice over the radio and Knight tried again, dropping his mine in the right place and as the explosion cleared, the dam wall crumbled and 200 million tons of water cascaded through. Gibson sent the code word "Dinghy" to indicate a successful attack, and they all turned for home, there being no aircraft left to attack the Sorpe.

McCarthy and Brown from the mobile reserve force both attacked the Sorpe but this was a far different type of dam, requiring a totally different attack technique. Unsurprisingly, it was not breached. Anderson was directed to the Sorpe but due to heavy mist was unable to bomb and brought the mine back. Ottley acknowledged orders to divert him to the Lister Dam but was shot down by light flak and crashed at 0235, 3 km north of Hamm; only the rear-gunner, Freddie Tees, survived, but he was badly burned. Gibson, returning home, saw Ottley's aircraft flying over Hamm at 500 feet and fall, burning, to earth. Townsend was directed to and bombed the Ennerpe, but this, too, resisted the attack.

The defences were now fully alerted and flak hit Young as he crossed the Dutch coast. He struggled on for a few miles before ditching off Castricum aan Zee at 0258. Although he had sent an SOS, and had twice successfully ditched in the past, the crew were all killed. It is likely that the picture of the remains of a crashed Lancaster on p89 of LANCASTER AT WAR I (Garbett & Goulding, ISBN 0 7110 0225 8, Ian Allan Ltd 1971) is that of Young's aircraft. The remaining aircraft reached Scampton safely.


Aftermath

Wallis, until then preoccupied with the scientific difficulties, was suddenly faced with the human cost of the operation; eight Lancasters and fifty-three men had failed to return. Gibson tried to console him without success, and eventually Wallis was given medication to help him sleep.

Nearly all of the men were decorated. Gibson received the Victoria Cross, Britain's highest award for gallantry. Martin, McCarthy, Maltby, Shannon and Knight were given the DSO; Hay, Hutchison, Leggo and Walker received bars to their DFCs; another 10 DFCs and 12 DFMs were awarded, and Townsend received the rare award of the CGM. At the Investiture, 617 were decorated en masse by the Queen; an altogether doubly unique event.

A great number of them later perished. Gibson was taken off flying and sent to America on a show-the-flag tour which was very successful. It was a task which he disliked, but approached with typical zeal. On return to England, he was considered too valuable to fly operations and was restricted to flying a desk. The divorce from operational flying, together with personal disorientation as to his status now the furore of the dams raid was over, caused him great distress.

He badgered Bomber Command to be allowed to operate again. Finally, after a personal appeal to Harris, he was posted to an operational unit. On the night of 19/20th September 1944, his Mosquito KB267 of 627 Sqdn crashed in Holland, killing Gibson and his navigator, S/L Jim Warwick. The cause is unknown, but Gibson and Warwick were very inexperienced on the Mosquito, and Gibson had not operated for a very long time. He was out of practice.

Recent research (October 2011) strongly suggests that Gibson and Warwick's Mosquito was shot down in error by Bernard McCormack, a 61 Sqdn Lancaster mid-upper air-gunner who mistook them for a Ju88. He made a taped confession which after his death came to light. This air combat event was also witnessed by another Lancaster crew, both sets of airmen seeing the Mosquito crash and giving an accurate location. No Ju88s were lost that night and none claimed a Mosquito victory. It is possible that the 'blue on blue' friendly fire incident was covered up by RAF authorities.

Gibson's crew were inherited by W/C George Holden, the next 617 C.O. and were killed on the night of 15/16th September 1943, except for Pulford, who was killed on 13th February 1944 with S/Ldr Bill Suggitt in a flying crash, and Trevor-Roper, who died on the infamous Nurembourg Raid, 30/31st March 1944, then with 97 Sqdn. Martin's crew survived except for Bob Hay, killed in a low level attack on the Antheor Viaduct; Shannon and his crew also survived, as did those of McCarthy and Munro.

Thanks to Larry Wright of the Nanton Lancaster Society in Canada who noticed that I had omitted to say that F/Sgt K.W. Brown, CGM, RCAF and crew (less Sgt. B Allatson), P/O Geoff Rice, F/Sgt. W.C. (Bill) Townsend CGM and crew who also survived the war, although Rice's crew were killed, and he taken prisoner of war, in December 1943.

Ken Brown, CGM, the last of the Canadian pilots who took part in the Dams raid, died on December 23rd 2002 in White Rock, BC, Canada, as the result of a heart attack.

617 were the only unit operating over enemy territory on this overnight period, but two other aircraft were also lost. A Stirling of 75 Sqdn experienced engine failure and was abandoned by most of the crew in mid air over Stoke-on-Trent, and the pilot, trying to crash land, was killed with one other crew member. Also a Wellington of 466 Sqdn vanished without trace over the sea, south of the Lizard.


Modern Points of View

It is trendy to denigrate the Dams Raid in particular and Bomber Command in general, but in 1943 the Allies had very little way to prosecute the war. U-Boat losses were mauling the Atlantic Convoys and taking awful tolls amongst ships bringing vital materiel across from America. Night-time operations by Bomber Command and daylight raids by the U.S. 8th Army Air Force were picking at Germany's industrial capacity in tactical bombing and trying to destroy the morale of the populace by carpet bombing of cities. Despite this, Germany's production was still increasing, but at a rate hampered by air attacks.

Bringing down the Ruhr Dams, despite the over 50 per cent loss rate sustained by the attacking crews, was a most tremendous tactical blow to Germany and did colossal, if temporary, damage. At home it was a most highly successful propaganda matter and brought foremost the efforts of the RAF, bringing in volunteers and focussing the population on the need to attack the enemy. Such successes were rare enough for every possible publicity angle to be capitalised upon. At a time when there weren't many other successes to write propaganda about, the Dams Raid caught the public's attention. Even 55 years on, the Dam Busters are still alive in the hearts and mind of the world. The film, of course, has a lot to do with this.

The Wellington aircraft used in the film has been moved from the RAF Museum at Hendon and is now (November 2014) benefiting from extensive restoration work at the Sir Michael Beetham facilities, Royal Air Force Museum at Cosford. There are occasional 'open days' at the workshops, the most recent being mid November 2014, so sorry, you just missed it.

Where the British High Command failed was to follow up on the attacks. The Germans moved heaven and earth to effect repairs, and these could have been bombed conventionally from high altitude once in a while, preventing a complete repair and ensuring that water supplies in the Ruhr Valley - Gemany's industrial heartland - were short, as well as canals being starved of water. It is worth remembering that the German canal system was instrumental in the movement of materiel, especially prefabricated U-Boats.

One correspondent says : "Bill Townsend (O for Orange) ended up working for the Civil Service. I had the privilege of working with him at Bromsgrove Unemployment Benefit Office in 1981. I remember him as being very quiet, but a true English gentleman. At the time, I didn't know who he was, as he never spoke of his background; but a few years later he died and the RAF did a flypast at his funeral. It was then that I found out who he was and what he had done."

I call the Dams Raid a resounding success, a triumph of British & Commonwealth determination, and I salute the men and women who brought it about.


Reading

"The Dam Busters" by Paul Brickhill. The edition I have is a very loved and battered copy by the Companion Book Club, but I have several. Brickhill is often inaccurate or wrong on the fine detail, but it should be borne in mind that the book was written well before serious research had been done into the topic.

"Enemy Coast Ahead" by Guy Gibson VC DSO DFC. My edition is the Goodall one, ISBN 0 907579 08 6, but I have several. A compulsory read.

"The Dambusters Raid" by John Sweetman, pub. Arms & Armour, ISBN 18540090607. Exhaustively researched to the point of being a technical manual, this book is required reading on the subject.
