Battle of Drina (6 sept. 1914 – 4 oct. 1914)

Description:

The Battle of Drina was fought between the Serbian and Austro-Hungarian armies in September 1914, during World War I. The Austro-Hungarians engaged in a significant offensive over the Drina river at the western Serbian border, resulting in numerous skirmishes (the Battle of Mačkov Kamen and the Battle of Gučevo being the heaviest ones). In early October, the Serbian Army was forced to retreat, and later regrouped to fight in the subsequent Battle of Kolubara.
