After the catastrophe in the Battle of Alamana, Dyovouniotis was called by Ali Pasha of Ioannina to serve him. However he refused, resulting in Ali Pasha kidnapping his son and holding him hostage. His son somehow managed to escape, but was then captured again, this time by Hurshid Pasha. Despite the kidnapping of his son, Dyovouniotis headed to Gravia and took key positions in the fierce battle which took place on the 8th of May. After the end of the battle, he called on the chiefs to close the passage to the Vasilika of Boeotia, believing that the Ottomans would seek to pass through that point. On the eve of the battle, Hurshid Pasha was forced to exchange Dyovouniotis' son with an Ottoman soldier who had been taken hostage by the Greeks.
