Reach for Glory is a 1962 British film directed by Philip Leacock and starring Harry Andrews, Kay Walsh and Michael Anderson Jr.
Too young to fight in the war and afraid it will be over by the time they come of age, the group members, who are also in the school's Army Cadet Force, initiate a battle with the local teenagers.
The Monthly Film Bulletin wrote: "The harm which the chauvinistic military propaganda necessary to sustain even the most righteous cause can have on unsophisticated minds is demonstrated with dramatic economy in this adaptation from John Rae's much-praised novel.
By deleting most of the author's side remarks on religion and patriotism and his social comment, including a superfluous ironic epilogue, it concentrates the better on this single theme from which so many more criticisms of the death-or-glory ethos follow.
Yet even after some inevitable bowdlerisation, the film's producers had difficulty in finding a British distributor for a work where there is nothing coy or quaint about the children or their war games, little humour and that often coarse or bitter, and no conventional sex, only devotion to one apparently still disturbing message.
