The Serbian army was in retreat, demoralized, in shortage of ammunition, Belgrade was in the enemy's hands, so the world already came to terms with the complete breakdown of Serbia. All available forces were needed for the crucial battle, which is why the corporal ranks were distributed to the youngsters in Skopje (hence the name), and were sent for Kolubara and Suvobor the next morning. There, the Serbian army, led by Živojin Mišić, pulled off one of the most important victories in World War I.
