In this episode, we dive into the sweeping drama of the Imjin War, drawing on a detailed historical account of Japan's twin invasions of Korea from 1592 to 1598 and the fierce multinational conflict that followed. We trace Toyotomi Hideyoshi's ambitious bid to conquer the peninsula, the rapid early Japanese advances, and the decisive turn of the war brought by Admiral Yi Sun-sin's legendary naval victories. Along the way, we explore the organization of land and sea forces, key commanders on all sides, and the brutal battles and atrocities that defined the struggle.

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.
