Greek naval planners had long recognized Lemnos as strategically vital due to its position at the entrance of the Dardanelles and the natural harbour of Mudros Bay. With the outbreak of the First Balkan War in 1912, Greece sought to establish naval dominance in the Aegean Sea and moved to seize the island from its small Ottoman garrison.
In October 1912, Greek forces landed on Lemnos and captured the island with minimal resistance. The Ottoman garrison, too small to mount a significant defense, was taken prisoner. Mudros Bay was promptly converted into a forward naval base, marking the opening engagement between Greek and Ottoman forces in the Aegean theatre of the First Balkan War.
Control of Lemnos allowed Greece to blockade the Dardanelles, obstructing Ottoman reinforcement movements and enabling the capture of remaining Ottoman-held Aegean islands over the following months. Formally ceded to Greece in 1914, the island's status remained contested due to World War I, and Greek sovereignty over Lemnos was not definitively confirmed until the Treaty of Lausanne in 1923.
