In 1832, the Bavarian prince Otto von Wittelsbac became King of Greece. The King was conducted to his new realm by a Greek delegation under Admiral Miaoulis; Brommy attached himself to this delegation, and became an officer in the Greek Navy. He was named commander of various warships, harbor master of Piraeus, and head of the admiralty court. Later he became first commandant of the naval school in Piraeus. In 1845 Brommy requested the Prussian King Frederick William IV for transfer into the Prussian navy, but this request was denied.
