The Second Battle of Komárom, sometimes known as the Battle of Ács, started on 2 July. The Austrian Supreme Commander Julius Jacob von Haynau and Schlik jointly attacked Komárom at 5 am. Görgey commanded the right flank and the middle, and Klapka commanded the left flank. Károly Leiningen-Westerburg fought against the Austrian army at Mocsa, but after the first couple of successes the Hungarian army had to withdraw. Klapka, seeing the bigger Austrian army, withdrew his legion from Szőny to Újszőny.
Leiningen started the fight, but the Austrian army won it. Major Rakovszky and Ernő Poeltenberg's attacks were more successful. They occupied the monastery and Herkálypuszta. After this, Klapka gave the order to retake Ószőny. The fight at Ószőny ended with Hungarian success.
Meanwhile, at the monastery the Austrians were successful: they occupied the vineyard on the hill and got nearer towards to the Hungarians. After they put their flag as a symbol of victory, they fought with the hiding Hungarians on Elisabeth Island. The Hungarians made them retreat to Ács.
After the attack on the monastery, around 5 pm, Klapka started to attack Ószőny. The Austrians won two attacks, but they lost the third and had to retreat to Mocsa. At the same time Poeltenberg and Görgey attacked the Ausrians and won. At Csém he confronted the Russian army and lost. Görgey had other unsuccessful attacks and he himself was injured. The battle ended around 8 pm. The Austrian army lost 900 men, the Hungarian loss was approximately 1,500 men.
