From Tim Butcher's June 28 article in the Daily Telegraph (emphasis added):
Princip was caught within seconds of firing his pistol, his bid for martyrdom doomed when the dose of cyanide he stuffed down his throat failed to kill him.Butcher is the author of "The Trigger: Hunting the Assassin Who Brought the World to War", published June 3 by Grove Press.
Two weeks short of his 20th birthday, Princip was too young to be executed as Austro-Hungarian law said the death sentence could only be given to criminals aged 20 or more. Instead, he was jailed, sentenced to 20 years solitary confinement with the condition that one day a month he was to receive no food. He died in a prison hospital on April 28 1918, his body so badly ravaged by skeletal tuberculosis that his right arm had had to be amputated.
Over the last century his voice has rarely been heard, drowned out by more powerful forces, not least Vienna which was desperate to use the assassination as a pretext to attack its small and potentially troublesome neighbour, Serbia. For this to work, Austria-Hungary worked to represent Princip and the assassination plot as the work of the Serbian government. And this alone is perhaps the greatest misrepresentation of the truth about Gavrilo Princip, with the historical record containing no convincing evidence to support the claim.
Wilfred Owen wrote of the patriotic invocation dulce et decorum est pro patria mori as "the old lie'', but I have come to see an even greater lie at the founding moment of the First World War. It is the lie used by Vienna in its deliberate misrepresentation of the Sarajevo assassination. On its hundredth anniversary, now is high time to straighten the record.
