V.M. Varga in “Unfinished Business”

The First World War was started by a sandwich. On June 28th, 1914, Gavrilo Princip, one of seven conspirators, failed to blow up the Archduke of Austria with a hand grenade. Demoralized, Gavrilo stopped for lunch at Schiller's delicatessen on Franz Joseph Street in Sarajevo. But as he was eating, the Archduke's driver, lost, pulled up outside the restaurant and stopped. Fate had delivered Gavrilo's target to him, and he would not miss twice.
