The Battle of Kraśnik (German: Schlacht von Kraśnik) started on August 23, 1914, in the province of Galicia and the adjacent areas across the border in the Russian Empire, in northern Austria (in present-day Poland), and ended two days later. The Austro-Hungarian 1st Army defeated the Russian 4th Army. It was the first victory by Austria-Hungary in World War I. As a result, the 1st Army's commander, General Viktor Dankl, was (briefly) lauded as a national hero for his success. The battle was also the first of a series of engagements between Austria-Hungary and Russia all along the Galicia front.
