The occupation of the island was a prolonged affair. The Greek landing force, commanded by Colonel Nikolaos Delagrammatikas, was quickly able to seize the eastern coastal plain and the town of Chios, but the Ottoman garrison was well equipped and supplied, and managed to withdraw to the mountainous interior. A stalemate ensued, and operations almost ceased from the end of November and until the arrival of Greek reinforcements in late December. Finally, the Ottoman garrison was defeated and forced to surrender on 3 January 1913.^[55]
