The assassination of archduke Franz Ferdinand in 1914 (which lead to World War 1) was carried out by the black hand; specifically Gavrilo Princip. Most sources conclude that he failed to kill himself by trying to drink cyanide Including Wikipedia. I was taught in school that he failed at trying to drown himself in a rather idiotic manner, which was trying to drown in a 3ft deep canal. Is this true? I found no evidence to support this.
My question: Did Gavrilo Princip really attempt to drown himself in a 3ft canal?
EDIT: I presume if you are reading this you are aware of Franz Ferdinand’s assassination but if otherwise, here is the Wikipedia page.
