Cause

By late 1915, Serbia faced a coordinated assault from German, Austro-Hungarian, and Bulgarian forces as part of a broader Central Powers campaign to eliminate Serbia as a military threat. The three Serbian armies, heavily outnumbered, were forced to retreat into the southwest of the country during the second half of November 1915.

Event

Central Powers forces under Prussian Field Marshal Mackensen launched a coordinated offensive in the Kosovo region, aiming to encircle and annihilate the retreating Serbian armies. The Serbs, unable to withstand the combined enemy strength, conducted a fighting withdrawal over the snow-covered mountains of Montenegro and Albania toward the Adriatic coast.

Consequence

The offensive ended in a decisive Central Powers victory. Serbia was subsequently occupied by Austria-Hungary and Bulgaria. The Serbian army, though greatly reduced, escaped total destruction by reaching the Adriatic coast, marking a significant shift in the balance of power in the Balkans during World War I.
