Battle of Isaszeg

The Battle of Isaszeg took place in the Spring Campaign of the Hungarian War of Independence from 1848 to 1849, between the Austrian Empire and the Hungarian Revolutionary Army supplemented by Polish volunteers. The Austrian forces were led by Field Marshal Alfred I, Prince of Windisch-Grätz and the Hungarians by General Artúr Görgei. The battle was one of several engagements between the Hungarian Revolutionary Army and the Imperial counter-revolutionary main army and was one of the turning points of the Hungarian War of Independence.

The Hungarian victory precipitated a series of setbacks to the Habsburg Imperial Armies in April–May 1849, forcing them to retreat from occupied central and western Hungary towards the western border and convinced the Hungarian National Assembly to issue the Hungarian Declaration of Independence. Windisch-Grätz was dismissed from the leadership of the Imperial forces in Hungary on 12 April 1849, six days after the defeat.
