Captain Dimitrijević and a group of junior officers planned the assassination of the King of Serbia.
On 11 June 1903, the group stormed the royal palace and killed both King Alexander and his wife, Queen Draga.
During the attack, Dimitrijević was shot three times, and the bullets were never removed from his body.

The Serbian Parliament described Dimitrijević as "the saviour of the fatherland", and he was appointed Professor of Tactics at the Military Academy.
He visited Germany and Russia, where he studied the latest military ideas.
During the Balkan Wars in 1912 and 1913, Dimitrijević's military planning helped the Serbian Army achieve several important victories.

Dimitrijević's main concern was what he viewed as the liberation of all South Slavs, especially Serbs, from Austria-Hungary.
Although Serbia was already an independent country, many Serbs in Bosnia and Herzegovina, Croatia and Vojvodina were still under Austro-Hungarian rule.
Dimitrijević, who used the code name Apis, became the leader of the secret Black Hand.
Dimitrijević had his men disguise as Albanians and commit political murders.
