This is the youngest soldier in World War I. Momčilo Gavrić lived in Serbia at the outbreak of the war. In 1916, Austro-Hungarian soldiers killed his father, mother, grandmother, his three sisters, and four of his brothers. His father happened to have sent Momčilo to visit his uncle, saving Momčilo’s life. Without a family or a home, Momčilo went to find the 6th Artillery Division of the Serbian army which was nearby. After hearing what had happened, the major accepted Momčilo into the unit and assigned him to a soldier — really a caretaker. That night, Momčilo showed the major where the Austro-Hungarian soldiers were and helped bombard them. Eight years old, and already avenging his family. At ten, he was promoted to Corporal and at eleven to Lance Sergeant. After the war, his major made certain he got assistance from a British mission and he completed his education in England before returning to Serbia.
