His journey eventually takes him to a sort of soup kitchen, where he enlists in the newly recreated army, which has replaced the (largely eaten) greyboys and Population Police. This is the third section of the novel. In the army, Tristram is shipped to an unknown location to fight in the war, though the reader later discovers that he is in Ireland. In his first battle he discovers that there is no real enemy; the purpose of the "war" is population control by winnowing out the socially expendable. Companies, led by junior officers trained to recite patriotic verse, are sent to a made-up Western Front style battlefield to kill each other. Every other member of his unit is shot down as they emerge from their trench, but Tristram slips through the barbed wire surrounding the miniature war zone and begins his journey back to England.
