Gallipoli Campaign Guide: Timeline and Outcome

Gallipoli campaign is the standard name for the Allied naval and land operations against the Ottoman defenses of the Dardanelles during the First World War. Searches for “Gallipoli War” generally refer to this campaign, not to a separate war. The land phase ran from April 25, 1915 until January 9, 1916. Allied forces ultimately evacuated without controlling the straits.

Why the Campaign Began

The Allies wanted to pass the Dardanelles, threaten Constantinople, and improve the route connected to Russia. Ottoman coastal defenses, artillery, and mines blocked the naval effort. Landings were then planned to capture ground controlling the waterway. The strategic aim was larger than any single beach or trench position.

Main Phases

The operation can be followed through the naval effort, April landings, fighting around Krithia and Anzac, the August offensive, and evacuation. Cape Helles and Anzac became separate centers of sustained combat. Suvla and Sari Bair were central to the August attempt to break the deadlock. Each phase requires its own dated maps.

Why It Stalled

Broken terrain narrowed movement and complicated coordination after the landings. Ottoman defenders contested high ground and reinforced threatened approaches. Beachheads remained, but local advances did not secure the wider strategic goal. Trench systems developed as both sides held close positions.

Outcome and Terminology

The final evacuation ended the Allied land presence without forcing the Dardanelles. Calling the operation the Gallipoli Campaign keeps it within the wider First World War. The phrase Gallipoli War remains useful as a search synonym but is less precise. Museum timelines and map collections provide the basis for the account on this page.
