On 22 July, Haynau started to move his troops towards Szeged from Budapest and on 24 July he followed them. He prepared for a hard and serious fight. Haynau precisely planned this battle: he divided his army of 46,000 people and 284 cannon into three parts. His plan was that he would take the Hungarian troops in a pincer movement at Szeged. Haynau sent his 3rd legion to Szabadka under the command of Georg Heinrich Ramberg. Haynau led his strongest legion and reached Kiskunfélegyháza without resistance. On 29 JulyMór Perczel and his legion arrived at Szeged.
Prelude
20,000 soldiers occupied the front at Szeged, which partly bordered the RiverTisza. Most of the 4th Hungarian legion also went there from Bácska under Richard Guyon's command, with Alessandro Monti's legion. The Emperor’s 1st legion occupied the Cegléd-Nagykőrös-Szolnok area under Franz Schlik's command. They reached the River Tisza. Haynau gave orders to Ramberg and Schlik: Ramberg to move from Törökkanizsa and Schlik from Makó towards the Hungarian troops. Haynau wanted to start a frontal attack in the hope that the three legions jointly would destroy the Hungarian troops. Dembiński thought that he lacked the power to defend Szeged and he retreated from the city on 1 August. He acted against other generals’ advice. Haynau was surprised when his legion occupied Szeged without a fight on 2 August. He ordered General Franz Liechtenstein to cross the River Tisza. Schlik had already crossed the river at Alpár on 1 August and was moving towards Makó. On 4 August came the first fight between Lenkey and the Emperor's troops. Lenkey's legion was only 7,000 strong, and most of them were inexperienced new recruits. Lenkey's main task was to stop Schlik, who wanted to close off an escape route towards Arad. Dembiński thought that if necessary he could escape towards to Turkey so he tried to cover his legion in the south. After he received news that the Austrian legions were battle-ready at Magyarkanizsa, he sent Guyon to Törökkanizsa on 2 August. The next day Dembiński also sent Monti's legion there. But Dembiński gave this order a little too late to be of use, and all he could do was debilitate the enemy on the Szentiván-Szőreg-Deszk front line, because Ramberg had crossed the River Tisza on 5 August. Dembiński also failed to stop Ludwig von Benedek, who had crossed the river on 3 August. Dembiński decided to attack, but his decision came too late, because the area had already been reinforced by the enemy. After this he redeployed his troops to Szőreg. He planned this as a defensive fight and dug his cannon into the embankment. was erected by the Szeged Municipal Council on the 150th anniversary of the battle.
Battle
On 4 August Haynau's troops crossed the river and the next day advanced towards Dembiński. After Dembiński received the news that Ramberg had broken through and crossed the river, and was very close to the Hungarians, he prepared to retreat. Haynau's legion was approximately 25,000 strong with 160 cannon, Dembiński's was 34,000 strong with 108 cannon. Dembiński didn't intend to use all of his cannon and he sent most of their surplus munitions en route for the planned retreat. Haynau bypassed the Hungarian troops and Dembiński deployed his cavalry too late, even though Fülöp Bechtold was only advancing very slowly. Haynau started his attack at the front line and after an hour and a half's battle he displaced the Hungarians. The Hungarians tried to attack. After Bechtold arrived and started to fight Dembiński's troops, Dembiński had to retreat. Polish and Italian legions, and Arisztid Dessewffy's, covered Dembiński and his troops during the retreat.
Aftermath
The battle finished in the evening and even though the Hungarian losses were relatively small in number, the defeat deeply affected the Hungarians' organisation and morale. The situation was more different at Szőreg than the battle at Kápolna, where the Hungarians waited for the enemy's cavalry and had their revenge. Whereas at Káplona the Hungarians engaged with the enemy's cavalry, at Szőreg they deserted. The refugee troops got help from the legions at Beba Veche, Dudeștii Vechi and Lenauheim, all of the cities are now part of Romania.
