Les briseurs de barrages

In the spring of 1942, the English design engineer, Barnes Wallis, is working on a revolutionary new bomb, capable of breaching Germany's hydro-electric dams. This film, with its unforgettable "Dam Busters March" by Eric Coates, recounts the story of the development of the bomb and the devising of special tactics for attacking Germany's industrial heartland. It is also a tribute to the genius of Wallis and the courage and skill of the men who made the concept work.

The great dams of western Germany, harnessing the energy of the rivers Moehne, Eder and Sorbe, were an important power source for the Nazi war effort. If the dams could be breached, then the loss of electrical energy and the collateral flooding would, it was hoped, cripple German industry and shorten the war.

As the film opens, Wallis is pondering the one central problem associated with bombing a dam. Any explosion in the water (and direct hits on the dam wall are too much to expect) is cushioned by the fluidity, and no structural damage results.

We see Wallis eagerly experimenting in his back yard, surrounded and assisted by his adoring children. His brilliant idea is this - if a bomb can be delivered at the correct shallow trajectory and the right high speed, it will 'skip' along the lake's surface like a pebble on a pond, strike the dam and slide down the wall. A depth-sensitive trigger could then detonate the bomb where it would do maximum damage.

The idea is a daring and imaginative one, and predictably enough, the various government departments are slow to see its merit. Wallis spends many disheartening hours waiting to speak to unsympathetic civil servants. In a lovely piece of ironic humour, a Whitehall mandarin points out to Wallis the difficulties inherent in obtaining a Wellington bomber for tests, and Wallis quietly suggests that his own role as the creator of the Wellington might be of some assistance.

Wallis is constantly being told that resources are scarce, that the communal effort requires sacrifices, and so forth. There is, he is told, "a very thin dividing line between inspiration and obsession". However, the eccentric genius persists, and eventually Churchill gets to hear of the idea. From that moment on, the project gathers momentum. 'Bomber' Harris, the chief of Britain's Bomber Command, sets up trials. The 'bouncing bomb' is at last a reality.

Major disappointments accompany the trials. The casing of the bomb has to be drastically re-designed, and it transpires that the aircraft will need to approach the dam considerably lower and faster than had been envisaged. The RAF's standard altimeters are useless at heights of 50 feet, and the resulting danger to crews of flying blind at almost zero altitude are unacceptable.

At this point, Commander Guy Gibson, the pilot who will lead the raid, has his own flash of inspiration. The spotlights in a variety theatre give him the idea of two converging light beams, shining downwards from aircraft to water, which will fix the plane's altitude precisely. If this all sounds a little 'Heath Robinson', it is nothing compared to the viewing gadget which is cobbled together to enable crews to align on the twin towers of the dam.

The climax of the film, the actual attack on the German dams, is rather a disappointment. Anti-aircraft tracer coming up from the German defenders is superimposed on the photographic matrix in the most amateurish of ways. The sound of the ground batteries is unrealistic, staying at a constant pitch and volume however the aircraft manoeuvre. The explosions are the poorest efforts of all, being no more than scraps of film and drawings, patched unconvincingly onto shots of a model dam.

Michael Redgrave does a commendable job of 'creating' Barnes Wallis for the screen, quintessentially English and understated, with his runner beans and his cricket jokes. The man's boyish enthusiasm comes across. In this respect the bathtub in the yard, the setting for his primitive experiments, serves two cinematic purposes, showing us the simple, unprepossessing genius of the English people, and explaining in visual terms exactly how the bomb will work.

Good use is made of genuine Air Ministry film of the bouncing bomb tests. If the ultimate effect on Germany's war capacity is exaggerated, this can be forgiven.

Richard Todd is terrific as Gibson, the tough little leader of the mission, the emotional man who is able through intense self-discipline to keep his feelings in check and do his duty. The powerful ending is almost too much to take, with the empty seats in the officers' mess, and Todd striding off in stiff-upper-lip fashion to 'write a few letters'. No English heart can fail to be stirred by that marvellous theme tune.

Now that everyone has taken their shots at this magnificent movie, just a couple of comments about it to help put it into context. A) No we didn't see Russian prisoners of war trying to flee for their lives and drowning. We didn't in fact see anybody drowning. But this is war and people die in wars, it's the nature of the beast. B) Seen in its current setting, especially in North America, the use of the name Nigger for the Black Labrador may seem upsetting and racist, explaining why that section of the movie is left out sometimes. But back in Britain in those days, it would not have been regarded as so nasty and derogatory as it now seems here. It was actually a fair common name for Black Labs at the time - though not any more of course. C) Nope, the movie isn't entirely accurate in all aspects - many years after I first saw it back in the UK, a bomber pilot from those days told me that they used not a Lancaster but I think a Halifax to plough into the ground. D) Maybe it did glorify Guy Gibson, but he earned that Victoria Cross, if I recall, for all his diversionary flights to draw off the flak from the other aircraft, who must have felt like sitting ducks the way they had to drop every bomb at precisely the same spot and height, very low over the water. If the movie gives him credit for thinking up the overlapping spotlights, we can take that as artistic licence. Finally, anything which slowed down the German war machine was crucial to Britain. This movie did its best with hardly-developed special effects and produced an exciting and fine picture, made still during the days of rationing in England. I know because I was there at the time. I was just six when this movie was made in 1954 but it's still a real favorite of mine, not least because we were living on the shores of Lake Windermere, England's largest lake, in the English Lake District at the time, and they flew right in over our house for about six weeks that summer to film some parts of it. Remember the scene where after one of the practice runs, they were picking bits of tree out of the undercarriage of one of the aircraft? My father always used to remind that they clipped one of our trees in the filming one day and he used to claim that those bits of branch and foliage actually came from our tree. I guess they probably didn't really and they faked it a bit for the movie, adding that bit of dialogue into the script after the incident because it showed how low they flew. Quite why they showed it in the landing gear I'm not sure, because of course they wouldn't have been flying with their landing gear down, but it is effective in showing how low they flew both in the raid and in the filming. I've always loved this movie though - it's a beaut, as they say - not least because I grew up with Black Labradors. I wept like a baby when Nigger died. Have just watched it for about the zillionth time - have literally lost count. It's still a fine and fitting tribute to the men who gave their lives in the raid all those years ago.

A very well made film, with a good script, actors and supporting cast. The film recreates the technical problems of the bombs development and squadron training. However, being made so soon after the raid the film ignores the relative lack of impact of the raid on German war production. However, the bravery of the air crews is very well portrayed. Guy Gibson, who was killed later in the war, won a Victoria Cross for his part in the raid and his leadership.

It appears that the attack sequences in The Dam Busters were the direct inspiration for the attack on the Death Star in the first Star Wars film. Some of the dialogue is word-for-word, and it is very interesting to watch these two films back to back.

Also, in the original edit of the film, the dog's name (a black labrador) was a historically accurate but socially unacceptable "Nigger". One edit changed the spoken word to "Trigger," while another release cut all scenes with the offending word. This was unfortunate, because parts of the plot became unintelligible -- the dog's name was one of the code-words used during the attack.

By God, this is as definitive as a war film gets. It's on every year, and is as much a part of Christmas as getting drunk and Monopoly. Everyone in this Sceptred isle knows the theme to Dam Busters, and it causes more people to stand up and salute than God Save The Queen. It has moustachioed R.A.F boys, politely bespectacled scientists, laughable special effects, and an entirely predictable ending. It's a British institution, and I don't know where we'd be without it. You can keep your devolution and your New Labour, I've got Dam Busters and I'm not bloody budging.
