He was executed for his part in the Hungarian Revolution of 1848, and is considered one of the 13 Martyrs of Arad. He commanded 100,000 men against Russian troops and surrendered because of the massive size of the encroaching Russian army. By doing so, he spared his men. On the night of his execution, he was said to be sleeping, with no anxiety about his impending death. He was executed around 4 AM by firing squad, along with two others. Prince Franz de Paula of Liechtenstein intervened at the last minute to spare the three from hanging, which was considered public humiliation.^[1]

After the final defeat and surrounding of the army, he had the opportunity to escape to Turkey, but one of his comrades, a Lieutenant-General, encouraged by Prince Franz von Liechtenstein, on 19 August next to Karánsebes laid down their arms before the Imperial troops. They were given terms that the soldiers would be spared but the officers would be subject to military discipline. General Liechtenstein later pleaded to his comrades at the military court to spare the lives of most, but to no avail; the Arad military court sentenced him to death by hanging. However the prince was able to convince the court to execute them by firing squad, which was seen as less of an insult since it was a military death rather than a criminal one. He was executed in the second group of four in front of a firing squad.

The executed were buried around the Arad castle. His body was later exhumed by his family and moved from the castle in secret. His body has been resting at the Margonyai estate since 1850.
