In this phase, the hiding place of objectives and the camouflage they were a main part in the effort of the war, Winston Churchill's maxim, the minister main English that says proceeding: “in the war, truth should be accompanied by an apparatus of the lies.” In some cases there would be a concentrated effort of hiding place on the enemy with a single reason of convincing; among other things, whose objective would be to create the confusion suggesting a scale of alternatives possible. Idea also suggested by great artists that influenced on way the camouflage from to First World War, of form cubist picassiane, and the camouflage of this new conflict that certainly should be surrealist daliniane.Em January of 1941, a team of the specialist given form for the general expert Wavell, commander of British forces in the north of Africa, created the Force A, dedicated to the counterintelligence and camouflage. Dudley Clarke is the thinking head of the Force A, he became the main coordinator of this force soon in the strategic theater Mediterranean and others of the war. He recruited then, Maskelyne for MI-9, a secret organization that specializes in techniques of the escape and of the escape.           

      Then, the surrealistic art of the magic of Maskelyne, had the opportunity of being used by the Force A, of the general Wavell where Maskelyne could apply their abilities to the task of hiding British forces of the aerial recognition germane. Developed 14 groups strong, clever informal as the “I group magic”, whose members Maskelyne chose for his team with abilities and qualities of the initiative and of the imagination, including a designer of history-in-frames besides - deviant criteria in the military context.

      Like this being, the trick knowledge and illusionism of allied Maskelyne to the cheap techniques and of little weight of the construction, the “I group magic” it produced the tanks done of the compensated wood and the canvas. The similar techniques of camouflage were used to also disguise the real tanks.

      On this same year, Maskelyne was involved in an operation elaborated that it diverted German bombardiers of the port of Alexandria adjusting - above a port falsified in a close bay; this involved to build models of the buildings, a light and even the batteries anti-aircraft. Some believe that the mysterious Code known as Percyfaw is also some codebook of same nature. Others think it doesn't pass of an invention planted by some organization occultist or even alien. A type of manuscript Voynich, in such a way hide that nobody knows what there it is written. The manuscript Voynich, different from the Percyfaw Code of obscure origins, appears accompanied by a letter that attributed his authorship to the famous English astronomer Roger Bacon. Various authors proposed and they based the hypothesis that the previous owner of the manuscript, except his author, he will have been John Dee, a disciple of Bacon. There does be who sees in the numbering of the pages, done a lot of the posteriori, the calligraphy of Dee. Maybe, the Percyfaw Code is a connection, at least esoteric, among a manuscript codified that it exists, but that cannot be read as Voynich, or an archetypal idea of the "Necronomicon" of writer H.P. Lovecraft.

      In spite of that, the services of intelligences and secret organizations, they must fall back upon codes as Hebrew of the Bible, Chinese Iching, the Persian Avesta, the writings sumerianas, Hindu, Nordic, before Columbus, of the American Indians Navajo and to the own Arcane Code Percyfaw, that would be copy led and kept the seven keys inside of the secret files.ft.E an ambitious camouflage plan in the Suez canal, through games of luminous bunches and mirrors to mislead the German bombardiers.
