The Battle of Debrecen was fought on August 2, 1849, between the Hungarian Revolutionary Army and forces of the Russian Empire, which intervened on behalf of the Austrian Empire to suppress the Hungarian revolution. On 30 July 1849, the commander of the Hungarian Army of the Northern Danube, General Artúr Görgei split his army in two, while he and the main part of his army marched towards Arad, he ordered to the I corps under the leadership of József Nagysándor to flank him from West against the Russians, by marching parallelly with his troops towards Debrecen. Nagysándor's I. corps was attacked and defeated by the hugely outnumbering Russian main army under Marshal Ivan Paskevich. This battle enabled Görgei to win a distance of several days from the Russian army, creating the possibility for him to join his armies with the Hungarian troops concentrated in Southern Hungary, and to defeat the Austrian main army of Field Marshal Julius Jacob von Haynau, before the Russians arrived. It was not Görgei's fault that this plan did not materialize.
