On 20 July, Germany’s political elite recalls the day in 1944 when Colonel Claus Schenk Count von Stauffenberg exploded a bomb intended to kill Hitler, and ran an abortive coup which ended in his own death and that of other plotters. To mark the anniversary, a military band in Berlin will thump out ‘Prussia’s Glory’, whereupon Defence Minister Ursula von der Leyen will urge massed recruits to emulate the rebels’ ethics.
