While the Western Front quickly descended into trench warfare, the fighting in the East remained highly mobile, spanning vast distances across Eastern Europe. In this episode, Sean and James discuss Austria-Hungary’s failed invasions of Serbia, Russia’s disastrous defeats at Tannenberg and the Masurian Lakes, and the massive but costly Russian victory over Austria at Galicia. Listeners will learn how poor leadership, logistical chaos, and ethnic divisions crippled the Austro-Hungarian and Russian armies alike. By year’s end, both sides were bloodied and exhausted, setting the stage for a long and brutal struggle in the East.
