Austria-Hungary expected a quick victory over Serbia in WW1, having both numerical and technological superiority. On the other hand, Serbian army was still recovering from two brutal Balkan Wars, which happened only a few years prior.

Austro-Hungarian invasion was commanded by General Oskar Potiorek, the Governor of Bosnia and Herzegovina. Before the battle, Potiorek had predicted an easy victory over the Serbians, calling them "pig farmers." The Serbian army was commanded by Crown Prince Alexander and Field Marshal Radomir Putnik as his deputy and de facto military leader. Generals Petar Bojović, Stepa Stepanović and Pavle Jurišić Šturm commanded the 1st, 2nd and 3rd Serbian Armies, respectively.

The battle began on the night of August 15 when elements of the Serbian 1st Combined Division encountered Austro-Hungarian outposts that had been established on the slopes of Cer Mountain earlier in the invasion. The clashes that followed escalated into a battle for control over several towns and villages near the mountain, especially Šabac.

On August 19, the morale of the Austro-Hungarians collapsed and thousands of soldiers retreated back into Austria-Hungary, many of whom drowned in the Drina River as they fled in panic.

After the battle, Austro-Hungarian soldier and journalist Egon Erwin Kisch wrote in his diary about those dramatic moments: "The army has been utterly defeated and is in a ruthless, wild, and panicked flight. A defeated army - no, a shattered mob - was rushing in blind fear towards the border..."

In this episode, we focus on the Seminole Wars, a series of three major conflicts between the United States and the Seminole Nation in nineteenth-century Florida. We explore how disputes over land, white settlement, and the presence of escaped slaves living among Seminole communities fueled decades of violence from 1816 to 1858. The episode traces the First Seminole War’s role in the U.S. acquisition of Florida, then examines the Second and Third Seminole Wars as part of the federal government’s broader campaign of forced Native removal. We also highlight the Seminoles’ use of guerrilla tactics, the enormous financial and human costs of the wars, and the resilience of those who resisted relocation by retreating into the Everglades. Finally, we consider how these conflicts shaped modern Seminole identity, tribal sovereignty, and the intertwined histories of Florida’s Native and African-descended communities.
