Throughout the Second World War there had been a potentially lethal Trojan horse inside Britain; from Comrie in Northern Scotland, down to Devizes in Wiltshire, in every city, in every race course of any note, in every football ground, were German POWs. Nearly a quarter of a million of them in fact; fit, virile young men, and a goodly number of them fanatical National Socialists. Now what would these young men do if they were armed and given a plan which transcended merely escaping? What if these desperate young men, were given the promise of an airborne landing by German forces in Britain: the vital support they needed to capture their main objective - London? This is the gripping story of their abortive mass escape plan and the covert operations that went with it.
