Before Princip could fire for a third time, the pistol was wrested from his hand and he was pushed to the ground. He managed to swallow a capsule of [[cyanide]], which failed to kill him.{{sfn | Butcher | 2015 | p=276}} The trial opened on 12 October and lasted until 23 October 1914. Princip and twenty-four people were indicted. All six assassins, except Mehmedbašić, were under twenty at the time of the assassination, while the group was dominated by Bosnian Serbs, four of the indicted were Bosnian Croats and all of them were Austro-Hungarian citizens, none being from Serbia.{{sfn | Butcher | 2015 | p=279}} The state's attorney charged twenty-two of the accused with high treason and murder and three with complicity in the murder. Princip stated that he regretted the killing of the Duchess and meant to kill Potiorek, but was nonetheless proud of what he had done.{{sfn | ''the Guardian'' | 2017}}{{sfn|Dedijer|1966|p=346}} The Austrian police investigators were eager to emphasise the exclusively Serbian nature of the assassination plot for political reasons,{{sfn | Butcher | 2015 | p=278}} but during his trial Princip insisted that, even though he was an ethnic Serb, his commitment was to freeing all south Slavs. All the chief conspirators mentioned the revolutionary destruction of Austria-Hungary and the liberation of the South Slavs as the motivation behind their act.{{sfn|Dedijer|1966|p=336}}
{{Blockquote|text=I am a Yugoslav nationalist, aiming for the unification of all Yugoslavs, and I do not care what form of state, but it must be free from Austria... The plan was to unite all South Slavs. It was understood that Serbia as the free part of the South Slavs had the moral duty to help in the unification, to be to the South Slavs as the Piedmont was to Italy... In my opinion every Serb, Croat and Slovene should be an enemy of Austria.

The Austro-Hungarian authorities tried to hide the fact that the conspirators included Croats and Bosniaks, going as far as changing the name of one of them in the press reports,{{sfn | Butcher | 2015 | p=279}} to portray the entire scheme as being of Serbian origin and carried out only by Serbs.{{sfn|Dedijer|1966|p=342}} Since it provided the weapons to the assassins and helped them cross the border, the [[Black Hand (Serbia)|Black Hand]] was implicated in the assassination. This did not prove that the Serbian government knew about the assassination, let alone approved of it,{{efn|After the war it was revealed that the Serbian government heard about a possible plot to assassinate the Archduke and had immediately issued orders for border guards to be on the lookout for young Bosnians.{{sfn | Butcher | 2015 | p=255}}}} but was enough for Austria-Hungary to issue a [[démarche]] to Serbia known as the [[July Ultimatum]], which led up to the outbreak of [[World War I]].{{sfn|Johnson|1989|p=|pp=52–54}} According to [[David Fromkin]] what the killings gave Vienna was not a reason, but an excuse, for destroying Serbia.{{sfn|Fromkin|2007|p=154}}

Princip was nineteen years old at the time and too young to be executed, as he was twenty-seven days shy of the twenty-year minimum age limit required by Habsburg law.{{sfn | Butcher | 2015 | p=279}} On Thursday 28 October 1914 the court found Princip guilty of murder and high treason, he received the maximum sentence of twenty years in prison, he was to serve out his sentence in a military prison within the [[Small Fortress (Terezín)|Habsburg fortress of Theresienstadt]] in northern [[Bohemia]] (now in the [[Czech Republic]]).{{sfn | Butcher | 2015 | p=280}}
