The Battle of Győr took place during the Summer Campaign of the Hungarian War of Independence. It was fought 28 June 1849 in the Hungarian city of Győr. The Hungarian Revolutionary Army was led by General Ernő Poeltenberg and General Artúr Görgei. The Austrian Empire was led by Julius Jacob von Haynau, with assistance from a Russian division led by Feodor Sergeyevich Panyutyin. After the Battle of Pered, Haynau's army, joined by the Habsburg emperor Franz Joseph I of Austria, crossed the Danube to the southern bank of the river, unnoticed by the Hungarian troops. They attacked the Hungarian units placed around Győr, Árpás, Marcaltő and Ihász, dividing György Kmety's division from the main troops and forcing them to retreat towards Southern Hungary. The imperials mustered greater than five times the number of Hungarian troops (69 350 imperials - 12 888 Hungarians) at the outset. Görgei was not in the city at the start of the battle, because he was in Pest, and arrived to Győr only towards the end of the battle. He led the Hungarian cavalry and Hungarian troops as they retreated from the city. After the battle, Görgei's troops retreated to the fortress of Komárom, followed by the imperials. Background Artúr Görgei's failed offensive ended with the Hungarian defeat in the Battle of Pered on 20 and 21 June 1849. This attack was chosen at an unlucky moment, because Austrian field marshal Julius Jacob von Haynau on 19 June moved his troops from the northern banks of the Danube to the southern banks, in order to prepare to advance towards the Hungarian capitals of Pest and Buda. But he still had enough troops to deploy with around 15 000 more soldiers in the battle than Görgei, thanks to the Russian division led by Lieutenant-General Feodor Sergeyevich Panyutyin, misleading the Hungarian commander, thinking that the imperials would remain on the northern bank. After the battle Haynau continued undetected, moving his troops to the southern bank. Haynau was very different from the earlier Austrian main commanders in Hungary; unlike the over meticulous Windisch-Grätz and the overanxious Welden, he was a very determined commander, who was not deterred from fulfilling his strategical plan, by minor setbacks, like the smaller defeats from Szered (on 9 June), Csorna, Seregakol and Aszódpuszta (on 13 June), Seregakol and Vásárút (on 14 June) and Pata and Sopornya (on 15 June), giving lectures to those commanders
