After graduating from the Vienna Theresianum in 1818 he joined the Imperial army's cavalry regiment. In 1845 he was the commander of the 2. (Hannover) cavalry regiment. Under his command also served future martyrs of Arad such as József Nagysándor and Károly Vécsey. In the spring of 1848 he stationed with his regiment in Nagykikinda (present-day Kikinda) thus he participated in battles against the Serb rebels. He initiated the first major victory in the southern land, capturing the Serbian camp in Perlasz (present-day Perlez) on 2 September.
Before the Battle of Pákozd, Lajos Batthyány wanted him to take the leadership of the main Hungarian Army but finally it did not happen because at the military council in Sukoró János Móga volunteered to fight against the Croats. Kiss served only as an observer in the battle. On 12 October he was appointed as a major general and took the leadership of the Banat corps.
