Allied Fleet Begins Dardanelles Bombardment

Context

By early 1915 the First World War had settled into a bloody stalemate on the Western Front, while the Ottoman Empire’s entry into the conflict on the side of the Central Powers had closed the Dardanelles Strait. This cutoff severed Russia’s primary warm-water supply route from the Mediterranean and Black Sea, prompting urgent appeals from the Russian high command for Allied assistance against Ottoman forces in the Caucasus.

Winston Churchill, then First Lord of the Admiralty, championed a naval operation to seize control of the straits, capture the Ottoman capital at Constantinople, and potentially draw neutral Balkan states into the war on the Allied side. British War Council approval came in mid-January after the Russian request, with Vice Admiral Sackville Carden tasked to develop and execute a plan relying primarily on battleships, minesweepers, and supporting vessels rather than a large-scale landing force at the outset.

The Dardanelles offered a narrow, heavily fortified waterway roughly forty miles long, with Ottoman defenses concentrated at the entrance forts of Seddülbahir on the European shore and Kumkale on the Asiatic side, backed by minefields and mobile artillery. Planners underestimated the resilience of these defenses and the challenges posed by the swift currents and narrow channels farther upstream.

What Happened

On the morning of February 19, 1915, an Anglo-French task force that included the British super-dreadnought HMS Queen Elizabeth, battleships such as HMS Cornwallis and HMS Vengeance, and French pre-dreadnoughts took station several miles offshore from the Dardanelles entrance. At approximately 07:58 the first Ottoman shot was fired from the Orhaniye Tepe battery at Kumkale; the Allies responded by directing long-range fire at the outer forts of Seddülbahir and Kumkale.

The initial bombardment lasted much of the day but produced disappointing results. Ships fired from beyond accurate range to conserve ammunition and avoid Ottoman return fire, achieving only scattered hits on gun emplacements. When several vessels closed to roughly three kilometers later in the afternoon, Ottoman gunners replied with mobile howitzers and fixed batteries, demonstrating that the forts remained operational. Limited ammunition and the need for precise direct fire prevented decisive neutralization that day.

Over the following week intermittent shelling and minesweeping operations continued under Carden’s direction, gradually damaging some outer defenses while Ottoman forces shifted artillery and laid additional mines. French Rear Admiral Émile Guépratte coordinated the multinational squadron, but persistent bad weather and the defenders’ ability to repair or relocate guns limited progress toward clearing a safe passage through the straits.

Aftermath

The February 19 action proved the opening move in a sustained naval campaign that reached its crisis on March 18, when a larger Allied force attempting to push into the Narrows lost three battleships to Ottoman mines and suffered severe damage to several others. Vice Admiral John de Robeck, who relieved Carden shortly afterward, concluded that naval forces alone could not force the straits without first silencing the shore batteries by land.

This assessment led directly to the decision to mount an amphibious invasion of the Gallipoli Peninsula. Allied troops, including British, French, Australian, and New Zealand formations, landed on April 25, 1915, initiating eight months of costly fighting that ended with a complete evacuation in January 1916.

Legacy

The Dardanelles naval attack and the subsequent Gallipoli campaign stand as one of the most conspicuous strategic failures of the First World War for the Allies. The operation cost tens of thousands of casualties on both sides without achieving its objectives, tarnished Churchill’s political reputation, and reinforced Ottoman and later Turkish national resolve.

In the longer term the campaign shaped postwar borders through the eventual partition of Ottoman territories and provided hard-won lessons on the difficulties of combined naval-amphibious operations that influenced planning for the Second World War. For Australia and New Zealand the landings became foundational national narratives commemorated annually on Anzac Day, while in Turkey the defense elevated commanders such as Mustafa Kemal and symbolized successful resistance against foreign invasion.
