Cause

A shortage of heavy Allied warships in the Aegean region left British monitors and destroyers at Imbros and the naval base at Mudros exposed to attack. The Ottomans exploited this gap by ordering their two most capable surface warships, the battlecruiser Yavuz Sultan Selim and light cruiser Midilli, to sortie into the Mediterranean.

Event

On 20 January 1918, the Ottoman squadron attacked and destroyed British Royal Navy monitors anchored off Imbros and then moved to assault the naval base at Mudros. While withdrawing, both Ottoman vessels sailed into a minefield; Midilli was sunk and Yavuz Sultan Selim was heavily damaged and forced to beach herself inside the Dardanelles.

Consequence

With Midilli sunk and Yavuz Sultan Selim immobilized and subjected to sustained Allied air attacks before eventually being towed to safety, the Ottoman Navy lost its most modern cruiser and its only battlecruiser, effectively ending its offensive capability for the remainder of World War I.
