First Balkan War: Greece completes its capture of the eastern Aegean island of Chios, as the last Ottoman forces on the island surrender.

The First Balkan War lasted from October 1912 to May 1913 and involved actions of the Balkan League against the Ottoman Empire. The Balkan states' combined armies overcame the initially numerically inferior and strategically disadvantaged Ottoman armies, achieving rapid success.

The Battle of Chios took place from 24 November 1912 to 3 January 1913 during the First Balkan War. It resulted in the capture of the eastern Aegean island of Chios by the Kingdom of Greece, ending almost 350 years of rule by the Ottoman Empire.

Chios is the fifth largest Greek island, situated in the northern Aegean Sea, and the tenth largest island in the Mediterranean Sea. The island is separated from Turkey by the Chios Strait. Chios is notable for its exports of mastic gum and its nickname is "the Mastic Island". Tourist attractions include its medieval villages and the 11th-century monastery of Nea Moni, a UNESCO World Heritage Site.

January 3 is the third day of the year in the Gregorian calendar; 362 days remain until the end of the year.
