[edit] Background

After the Battle of the Drina, the Serbian army retreated to the right bank of the Kolubara river. The Serbian Army had 250,000 poorly equipped soldiers and the Austro-Hungarians had a well-equipped force of 280,000 men. On 16 November 1914, Austro-Hungarian Balkan Army group (5th and 6th Army), commanded by Field Marshal Oskar Potiorek, launched an attack across the river. Potiorek's goal was to gain control over the railroad that led from Obrenovac to Valjevo and to use it for supplying his troops instead of using muddy roads in Macva. The 5th Army, which held the northern part of the front, captured the town of Lazarevac which was held by the Serbian 2nd Army. In the south, parts of the 6th Army (15th and 16th Corps) attacked the 1st Serbian Army, captured Mount Maljen on 24 November, and put the Serbian left wing in a difficult situation. On 25 November, the 5th Army pushed back 2nd and 3rd Army, crossed the Ljig river and flanked the 1st Army.

Because the Serbian First Army was in difficult situation, its commander, General Zivojin Misic, wanted to abandon his current positions and retreat to the new position in front of Gornji Milanovac. His plan was to delay combat, rest his troops, and then launch a counteroffensive. However, Putnik did not approve of the plan. He warned Misic that in that case other armies would also have to retreat, and Belgrade would have to be abandoned. But Misic firmly believed that his plan was the right one, and said to Putnik that the orders had already been given, and that he would not change them while he was in command. In the end, Putnik accepted his plan.

When Belgrade was abandoned, Potiorek made a new plan. He wanted to amass the entire 5th Army in the Belgrade region and annihilate the 2nd army which was on the right wing of the Serbian front. Then the 5th Army would turn to the south, get behind the enemy and force him to capitulate. But Potiorek underestimated the offensive capabilities of the 1st Army in south. He thought that this army was too tired and weakened to do more than hold and that it would do nothing while his forces were maneuvering.

Austro-Hungarian soldiers were very tired even before this maneuver began. While they were marching, Serbian troops were resting in their new positions. On the 2 December, Misic finished all preparations for an attack. Putnik ordered the attack of the entire Serbian army on 3 December. That was an ideal moment, because the largest Austro-Hungarian formation, the Combined Corps, was by then out of combat, marching north.

[edit] Counterattack

On the 3 December, the 1st Army launched an attack against the surprised 16th Corps. The attack was supported by the Uzice army from the left wing. 16th Corps suffered heavy casualties and was pushed back. On the 4 December, 17th Corps tried to hold the advance of the 1st Army, but failed. Potiorek ordered an attack of the 5th Army so that he could complete his operation before the 6th army is defeated. However, the Combined Corps was still on its march.

On the 5 December, 1st Serbian Army captured Mount Suvobor44°07′09″N 20°11′07″E / 44.11917, 20.18528 (Mount Suvobor), the main defensive position of the 6th Austrian Army. Meanwhile, the 3rd Serbian army had failed to push the 15th Corps off of Mount Rudnik, and Uzice army suffered heavy casualties. However, these formations pressured the Austro-Hungarian forces and helped the 1st Serbian Army to achieve a breakthrough. In the evening, Combined Corps arrived at its new position with very tired soldiers.

On 6 December, Potiorek ordered the retreat of the 6th Army on the left bank of the Kolubara. Combined Corps finally attacked the 2nd Army, but the attack was easily stopped. The Combined Corps on the 8 December launched a major attack. but the 2nd Serbian Army managed to hold its position. Other units of the 5th Army were more successful, but it was too late. The 1st Serbian Army had captured Valjevo and was pushing north. Marshal Putnik reinforced the 2nd Serbian Army with fresh troops and ordered an attack before the Austro-Hungarians could fortify their positions. On 12 December, Stepanovic's 2nd Serbian Army attacked and defeated the 8th Corps. The 5th Army had to leave Belgrade and cross the Sava River on 15 December. The battle was over.

The Serbian Army captured 43,000 enemy soldiers, and the number of Austro-Hungarian casualties was even greater. Misic was promoted to Vojvoda (Field Marshal), while the Austrian, Potiorek, was retired.

In 1914 the Austro-Hungarian Balkan Army Group lost around 227,000 men (out of a total of 450,000 engaged in the battles), while the Serbian army lost around 170,000 men (nearly its entire pre-war strength).

[edit] Results

Austria had taken massive losses and yet failed to conquer or defeat Serbia. Meanwhile it was under intense pressure from the powerful Russian army on its eastern frontier. Since Serbia did not really pose a threat to Austria, for the next 10 months the Austrians did nothing against Serbia and most of the forces in the area were transferred to the Italian front.

On the other hand, although victorious, Serbian losses were even larger as a percentage of their army strength. Coupled with a terrible typhus epidemic that raged through the countryside during the winter, Serbia was content to stay on the defensive in 1915 and hope for increased Allied support. Sadly for Serbia, this support was to come too little and too late.
