Mehmedbašić was the first of the young assassination team to be passed by the motorcade on the Appel Quay, just before the Cumurja Bridge. As the Archduke’s car neared, he was about to throw his bomb but panicked.
Čabrinović, who was standing by river, was the first to act. He primed his bomb and threw it. The driver saw it coming and accelerated. It exploded beneath the car travelling behind the Archduke’s, the third in the motorcade, injuring several officers. A small splinter cut Sophie’s cheek. The Archduke and his wife were unharmed, but some of those travelling with them were injured.
Čabrinović swallowed his cyanide powder and jumped into the shallow waters of the river Miljacka. The poison didn’t work and he was arrested.
