19 year old Gavrilo Princip is dying of TB. With the knowledge that he will soon die, he is not afraid to kill his target as he has nothing to lose. He wants to take revenge on the heir to the throne and has planned to murder him with the 'Black Hand', on orders from their leader in Serbia.
The Black Hand gather in a Pâtisserie with a suite case, which has a load of smuggled weapons from their leader in Serbia. They now plan out their mission to assassinate the heir.
The Lucky Sandwich
Three new members of the Black Hand join them and they get into position on the side of the road that Archduke Franz Ferdinand will be touring along. They all have cyanid that they will use after they have killed him. They know he would come on the route, as it has been published.
When the car passes the first man of the Black Hand, he does not respond. The second member hurls a grenade which misses and bounces off the car, injuring some bystanders. This man then attempts to commit suicide, but fails as the cyanid was out of date. Later, he is tortured for information, but does not give it up. The other members are to shocked to act and they fail.
Now the Black Hand has failed, Gavrilo Princip heads off to buy a sandwich. Franz Ferdinand is now in his car driving to visit the injured in hospital. The driver then by chance, takes a wrong turn and drives onto the road that Gavrilo Princip is on. Princip doesn't miss his chance. BANG! Both the heir to the throne and his wife are dead!
All the members of the Black Hand that were involved in the assassination were quickly arrested. Some of the members died of TB, others were hung and some were sent to jail. Due to his death a chain of events were set in motion and this lead to WW1 being officially started and led to many lives being lost.
