Lieutenant Colonel Philip Toosey of the British Army was the real senior Allied officer at the bridge in question. Toosey was very different from Nicholson and was certainly not a collaborator who felt obliged to work with the Japanese. Toosey in fact did as much as possible to delay the building of the bridge. While Nicholson disapproves of acts of sabotage and other deliberate attempts to delay progress, Toosey encouraged this: termites were collected in large numbers to eat the wooden structures, and the concrete was badly mixed. Some consider the film to be an insulting parody of Toosey. On a BBC "Timewatch" programme, a former prisoner at the camp states that it is unlikely that a man like the fictional Nicholson could have risen to the rank of lieutenant colonel, and, if he had, due to his collaboration he would have been "quietly eliminated" by the other prisoners. Julie Summers, in her book "The Colonel of Tamarkan", writes that Boulle, who had been a prisoner of war in Thailand, created the fictional Nicholson character as an amalgam of his memories of collaborating French officers. He strongly denied the claim that the book was anti-British, although many involved in the film itself (including Alec Guinness) felt otherwise. Ernest Gordon, a survivor of the railway construction and POW camps described in the novel/film, stated in a 1962 book, "Through the Valley of the Kwai": "In Pierre Boulle's book "The Bridge over the River Kwai" and the film which was based on it, the impression was given that British officers not only took part in building the bridge willingly, but finished in record time to demonstrate to the enemy their superior efficiency. This was an entertaining story. But I am writing a factual account, and in justice to these men—living and dead—who worked on that bridge, I must make it clear that we never did so willingly. We worked at bayonet point and under bamboo lash, taking any risk to sabotage the operation whenever the opportunity arose."
