the Hum train station, on the way to Sarajevo, gendarmes searched the train; fearing they were on to him, he threw the knife out the window. Potiorek was planned to be assassinated at the end of March 1914, when the new mufti Čaušević was to be enthroned in Sarajevo. However, upon hearing that Archduke Franz Ferdinand of Austria would come to Sarajevo on Vidovdan, the Black Hand changed their minds. The Archduke's scheduled visit on Vidovdan (28 June), a Serbian national holiday, was perceived as an insult. Ilić summoned Mehmedbašić and informed him on 26 March that the plan now was to murder Archduke Franz Ferdinand, as ordered by Apis, and Mehmedbašić should stand by for the new operation. Mehmedbašić said during talks of the assassination that "half of Bosnia and Herzegovina will join the plot, and the other half will approve everything we do".

The next, Čabrinović, threw his bomb which bounced off the royal car and exploded under the following car, wounding two in the car and twenty in the crowd, then failed at suicide as his cyanide did not work and was arrested. Princip, hearing the explosion, believed the assassination to be a success and went to a nearby café. The motorcade made it safely to the Hall, and speeches were held, in which Franz Ferdinand was concerned about the injured and insisted on visiting them at the hospital, advised against by von Morsey but supported by Potiorek. As the motorcade took a wrong route to
