The Dardanelles Campaign in World War I: A Complete Guide for 2026

The Dardanelles Campaign, also known as the Gallipoli Campaign, was a major Allied military operation during World War I aimed at securing a sea route to Russia and knocking the Ottoman Empire out of the war. Launched in 1915, the campaign ultimately ended in failure but remains one of the most studied and commemorated events of the Great War.

What Was the Dardanelles Campaign?

The Dardanelles Campaign was a strategic Allied offensive designed to open a supply route to Russia through the Dardanelles Strait and capture Constantinople (modern-day Istanbul), the capital of the Ottoman Empire. The campaign involved naval attacks followed by a large-scale amphibious landing at Gallipoli Peninsula. The goal was to establish a secure route for Allied ships to pass through the strait, supply Russia, and potentially force the Ottomans to surrender. However, strong Ottoman defenses, poor Allied planning, and logistical challenges led to a prolonged and bloody stalemate.

How Did the Campaign Begin?

The campaign was conceived in late 1914 after the Ottoman Empire joined the Central Powers. The Allies, particularly Britain and France, feared that Russia would be cut off from Allied supplies due to the Ottoman blockade of the Dardanelles. Winston Churchill, then First Lord of the Admiralty, proposed a naval assault to force open the strait. On February 19, 1915, a British-French fleet began bombarding Ottoman forts along the Dardanelles. The initial naval attack failed after several warships struck mines. Following this, plans shifted to a full-scale invasion of the Gallipoli Peninsula.

When Did the Dardanelles Campaign Take Place?

The Dardanelles Campaign unfolded over eight months, from February 1915 to January 1916. The naval phase lasted from February 19 to March 18, 1915, culminating in the loss of several Allied battleships. The land phase began on April 25, 1915, with the ANZAC (Australian and New Zealand Army Corps) landing at what is now known as Anzac Cove. British and French forces also landed at Cape Helles and other points along the peninsula. The campaign ended in evacuation between December 1915 and January 1916, after Allied forces withdrew under the cover of night with minimal casualties.

Key Battles and Phases

The Gallipoli Campaign consisted of several critical phases:

• Naval Attack (February–March 1915): The Allied fleet attempted to force passage through the Dardanelles but was repelled by Ottoman minefields and artillery.
• Amphibious Landings (April 25, 1915): ANZAC forces landed at Anzac Cove under heavy fire, establishing a precarious foothold. British forces landed at Cape Helles but faced intense resistance.
• Kum Kale and Sedd el Bahr (April 25–26, 1915): French forces supported the British landings with an assault on the Asian side of the strait.
• First Battle of Krithia (May 1–4, 1915): British forces attempted to advance toward Krithia but were halted by Ottoman defenders.
• Battle of Lone Pine (August 6–10, 1915): Australian forces launched a diversionary attack to draw Ottoman troops away from a larger British offensive.
• Battle of Chunuk Bair (August 6–10, 1915): New Zealand troops captured Chunuk Bair but were later forced to retreat.
• Evacuation (December 1915–January 1916): After months of stalemate, Allied forces withdrew from Gallipoli in a meticulously planned overnight operation.

Why Did the Campaign Fail?

The Dardanelles Campaign failed due to a combination of factors. The Ottomans had prepared extensive defenses, including trenches, mines, and artillery positions. The Allies underestimated Ottoman resilience and failed to coordinate effectively between naval and land forces. Poor intelligence, inadequate maps, and communication breakdowns further hampered operations. Additionally, disease and harsh conditions in the Gallipoli Peninsula—such as dysentery, typhoid, and extreme heat—devastated Allied troops. By the end of the campaign, over 130,000 soldiers from both sides had lost their lives, with countless more wounded or missing.

Casualties and Aftermath

The human cost of the Gallipoli Campaign was staggering. The Ottomans suffered approximately 86,000 casualties, including 65,000 deaths. The Allies, including British, French, Australian, New Zealand, and Indian troops, incurred over 250,000 casualties, with more than 46,000 deaths. The campaign became a defining moment for national identities in Australia and New Zealand, where April 25 is commemorated annually as ANZAC Day. For Turkey, the victory at Gallipoli became a symbol of national pride and resistance, with Mustafa Kemal (later Atatürk) emerging as a prominent military leader.

Legacy and Historical Significance

The Dardanelles Campaign reshaped military strategy and left a lasting impact on global history. It demonstrated the challenges of modern warfare, including trench combat and amphibious landings. The campaign also highlighted the importance of intelligence, logistics, and leadership. Today, Gallipoli is a site of pilgrimage and remembrance.
