Alexander I of Yugoslavia - Balkan Wars and World War I

Balkan Wars and World War I

In the First Balkan War in 1912, as commander of the First Army, Crown Prince Alexander fought victorious battles in Kumanovo and Bitola, and later in 1913, during the Second Balkan War, the Battle of Bregalnica. In the aftermath of the Second Balkan War Prince Alexander took sides in the complicated power struggle over how Macedonia should be administered. In this Alexander bested Col. Dragutin Dimitrijević or "Apis" and in the wake of this Alexander's father, King Peter, agreed to hand over royal powers to his son. On 24 June 1914 Alexander became Regent of Serbia.

At the outbreak of World War I he was the nominal supreme commander of the Serbian army - true command was in hands of Chief of Staff of Supreme Headquarters - position held by Stepa Stepanović (during the mobilisation), Radomir Putnik (1914–1915), Petar Bojović (1916–1917) and Živojin Mišić (1918). The Serbian army distinguished itself in the battles at Cer and at the Drina (the Battle of Kolubara) in 1914, scoring victories against the invading Austro-Hungarian forces and evicting them from the country.

In 1915 the Serbian army with the aged King Peter and Crown Prince Alexander suffered many losses being attacked from all directions by the alliance of Germany, Austria-Hungary and Bulgaria. It withdrew through the gorges of Montenegro and northern Albania to the Greek island of Corfu, where it was reorganized. After the army was regrouped and reinforced, it achieved a decisive victory on the Macedonian Front, at Kajmakcalan. The Serbian army carried out a major part in the final Allied breakthrough in the autumn of 1918.
