Serbian and Montenegrin front Greek front The Battle of Elli (Greek: Ναυμαχία της Έλλης, Turkish: İmroz Deniz Muharebesi) or the Battle of the Dardanelles took place near the mouth of the Dardanelles on 16 December [O.S.

3 December] 1912 as part of the First Balkan War between the fleets of the Kingdom of Greece and the Ottoman Empire.

Rear Admiral Pavlos Kountouriotis landed at Lemnos, while the Greek fleet captured a series of islands.

During the battle, Kountouriotis, frustrated by the slow speed of the three older Greek ironclads Hydra, Spetsai and Psara, hoisted the Z flag which stood for "Independent Action", and sailed forward alone at a speed of 20 knots, against the Ottoman fleet.

[1] This victory was quite significant in that the Ottoman Navy retreated within the Straits and left the Aegean Sea to the Greeks who were now free to liberate the islands of Lesbos, Chios, Lemnos and Samos and others.
