The Forgotten Front: WWI's Serbian Campaign & The Great Retreat

In this episode of pplpod, we dive deep into the harrowing history of the WWI Serbian Campaign. Discover how a heavily outnumbered Royal Serbian Army defied the odds to repel the initial 1914 Austro-Hungarian "punitive expedition," securing the very first Allied victory of World War I at the Battle of Cer.

We explore the catastrophic turning point in late 1915 when German, Austro-Hungarian, and Bulgarian forces launched a coordinated, three-sided invasion, giving the Central Powers temporary mastery over the Balkans. Listen as we trace the tragic and historic "Great Retreat," where the Serbian military and civilian refugees were forced into a devastating winter evacuation through the mountains of Montenegro and Albania.

This episode also examines the staggering human cost of the WWI military history in this region. We discuss how Serbia lost more than 29% of its overall prewar population—and a devastating 60% of its male population—to combat, starvation, and the worst typhus epidemic in world history. Finally, learn about the dramatic 1918 Entente breakthrough on the Macedonian front, which shattered the Bulgarian lines and led to the ultimate liberation of Serbia.

Whether you are a World War I history buff or just discovering the complex history of the Balkan theatre, this episode sheds light on one of the most intense upsets and devastating demographic tragedies in modern military history.
