On June 11, 1828, Brommy was advanced to the rank of Commander, and given command of the modern steam corvette "Epicheiresis" (the former "Enterprise"). In the squadron of Greek admiral Andreas Vokos Miaoulis, Brommy took part in the battles in the Gulf of Arta, and participated in the recapture of Missolonghi. In 1829, during the turmoils of the third Greek civil war, Miaoulis and Brommy supported the bourgeois camp. Soon, however, Brommy left Greece and returned to Saxony. In Meissen, he published an autobiographical novel under the pseudonym R. Termo.
