1915–1916
The Story of the Gallipoli Campaign
Gallipoli was shaped by geography, naval strategy, amphibious warfare, trench fighting and the determination of soldiers on both sides.
During the First World War, Britain and France sought a way through the Dardanelles toward the Ottoman capital,
Constantinople, while also hoping to create a maritime route connected with their ally Russia. Early operations focused on forcing
the strait by naval power. The major Allied naval attack of 18 March 1915 failed after mines, coastal artillery
and Ottoman defenses inflicted serious losses on the fleet.
Allied planners then turned to a land campaign. On 25 April 1915, British and French forces attacked in the
southern sector around Cape Helles, while troops of the Australian and New Zealand Army Corps—ANZAC landed farther
north at Arıburnu. The rugged terrain immediately became decisive. Steep slopes, deep gullies and narrow ridges slowed the Allied
advance and gave Ottoman defenders opportunities to block routes toward the interior.
One of the most important Ottoman commanders in the opening phase was Lieutenant Colonel Mustafa Kemal, commander
of the 19th Division. His intervention on the heights above the Anzac landing helped prevent the Allied troops from gaining the
commanding ridge system on the first day. The fighting soon settled into a brutal trench stalemate in which opposing positions
were sometimes separated by only a short distance.
A major attempt to break the deadlock came with the August Offensive. The campaign expanded around Suvla Bay
and the Sari Bair range, while fierce actions were fought at Lone Pine, The Nek and Chunuk Bair. Although individual
positions changed hands, the Allies failed to secure the decisive heights needed to transform the campaign.
By late 1915, the Allied leadership concluded that the peninsula could not be held at an acceptable cost. The Anzac and Suvla
positions were evacuated in December 1915, followed by the remaining Helles forces in early January 1916. The campaign ended in
an Allied military defeat and an Ottoman victory, but its memory developed differently across Türkiye, Australia, New Zealand,
Britain, France and the many other communities whose soldiers served here.
Casualty totals vary depending on whether sources count only battlefield losses or also include disease and sickness. What is
beyond dispute is the enormous human cost. Today, Gallipoli is best approached not simply as a story of victory and defeat, but
as a landscape where hundreds of thousands of soldiers endured combat, injury, illness, separation and loss.
