March on the Drina is a 1964 Yugoslav war film co-written and directed by Žika Mitrović.
The film is based on a historical event, the Battle of Cer, which took place in 1914 during World War I.
The film chronicles the experiences of a Serbian artillery battery of the Combined Division as it makes a forced march to the Cer Mountain in western Serbia to meet Austro-Hungarian troops who have invaded the country by crossing over the Drina River.
Upon withdrawal, Major Kursula goes to the village Tekeriš, where the supreme command of the Serbian army resides.
In the afternoon, the army counter-attacked and managed to defeat the enemy troops and force their withdrawal across the Drina River into Bosnia.
