On the 28th August 1824, in the evening, the Greek and the Turkish fleet battled. On the 29th, at dawn, Miaoulis, the Greek admiral, with 22 ships sailed from Lipsos in order to attack the Turkish. Hosref, the Turkish commander, withdrew and reached the coast of Kalymnos. By noon , both fleets had met in between Leros, Kalymnos and the bay of Gerondas. The outcome of this sea battle results in the establishment of freedom for the Greeks. Kalymnos becomes part of Samos when Kapodistrias establishes the sixth administration of the Greek State.
However, the island doesn't remain as part of this state. For a period of 117 years, Kalymnos will not succeed in being considered Greek. Kapodistrias's sixth - and partly fifth - administration will not be included within the boundaries of the Greek State, according to the Protocol on the 3rd February 1830.
Kalymnos, Leros, Patmos and Ikaria will compose an administrative post of the Othomanian Empire and will be called 'Tetranisos' ; new privileges and expansion of the old ones will be granted.
