The Battle of Maglaj was a military engagement between Austria-Hungary and the Ottoman Empire that took place on 3–5 August 1878 as part of the Austro-Hungarian military campaign in Bosnia and Herzegovina in the Bosnian vilayet for control of the strategic town of Maglaj. The Austro-Hungarian expeditionary Force was surprised by the stiff resistance of the Bosnian Muslims when crossing the Bosnia River near the city, and managed to gain control of the area only after a secondary combat strike. The ferocity of the fighting at Maglaj subsequently became popular among the soldiers, and thanks to returning Czech soldiers, it penetrated into the Czech language by establishing the term maglajs as something disordered and confusing.
