From 5 January 1849 he was brigadier, from 18 February commander of a division in the Army of the Northern Danube led by Artúr Görgei.

[1] His decision not to attack with his army corps the Austrians led by Marshall Alfred I, Prince of Windisch-Grätz in the Battle of Isaszeg, was considered to be a big mistake, because it could have led the destruction of the united Habsburg forces in Hungary[2] thus immediately ending the war.

The reason for his resignation, in addition to his opposition to the declaration of independence, may have been that after the Battle of Isaszeg, the confidence of the military leadership in his commanding abilities was shaken.

After Hungary's Surrender at Világos in front of the Russian troops, and the end of the Hungarian War of Independence, he was sentenced to 10 years in prison by the Austrian authorities, but in 1850 he was pardoned.

Between 1868–1875 he was a parliamentarian in the House of Representatives, then he was elected as president of the Central Honvéd Association.
