Battles of the Gallipoli Campaign were a series of land and naval operations on the Gallipoli Peninsula and in the Dardanelles during World War I, involving large-scale amphibious assaults, trench warfare, and combined-arms attempts to force the straits and knock the Ottoman Empire out of the war. Allied aims—chiefly those promoted by Winston Churchill, Lord Fisher, and the British Admiralty—sought to secure a sea route to Russia, relieve pressure on the Eastern Front, and capture Istanbul; Ottoman defenders under Mustafa Kemal Atatürk, Liman von Sanders, and local commanders conducted determined defense culminating in an Allied withdrawal. The campaign included distinct landings, naval bombardments, raids, and logistical operations that influenced later Gallipoli Campaign historiography and national memories in Australia, New Zealand, Turkey, United Kingdom, and France.
The Allied operation grew from strategic discussions at the Admiralty and inter-Allied councils such as the Committee of Imperial Defence and the Anglo-French Naval Commission, with proponents including Winston Churchill, John Jellicoe, and Fisher, and critics like Sir Ian Hamilton and officers tied to operations in the Western Front and Dardanelles Commission. The strategy linked to crises on the Eastern Front and actions against the Central Powers such as Germany and the Austria-Hungary; planners envisaged forcing the Dardanelles straits to open a supply line to Russia and threaten Istanbul, a political objective debated alongside the diplomatic context of the Treaty of London and naval logistics involving Royal Navy squadrons, French flotillas, and armored cruisers. Ottoman defensive preparations were influenced by German advisers including Otto Liman von Sanders and regional commanders like Mustafa Kemal Atatürk, with fortifications at positions such as Sari Bair, Anzac Cove, and Cape Helles.
Land operations began with the amphibious assaults on 25 April 1915—landings at Anzac Cove by the ANZAC under William Birdwood, and at Cape Helles by divisions commanded by Aylmer Hunter-Weston and Herbert Cox. Major battles included the Battle of Krithia (I, II, III) around Krithia and Achi Baba; the Gallipoli landing actions at Anzac Cove leading to the Battle of Lone Pine and Battle of Chunuk Bair (part of the Sari Bair Offensive), and the Third Battle of Krithia operations linking to assaults on Hill 971 and Hill 60. Other significant actions comprised the Battle of Gully Ravine and localized attacks at Sulva Bay and Krithia Vineyard. Stalemate and attrition produced trench systems comparable to the Western Front; units included the New Zealand Expeditionary Force, Australian Imperial Force, Royal Naval Division, Royal Marines, and French colonial troops from Algeria and Senegal.
Naval operations featured combined bombardments, minesweeping, and fleet actions by the Royal Navy, French Navy, and Imperial Russian naval elements against Ottoman coastal batteries manned by units under Hamidiyye and German artillery advisors. The initial naval attempt to force the Dardanelles in March 1915 culminated in the loss of pre-dreadnoughts such as HMS Irresistible and HMS Ocean and the battle-cruiser HMS Triumph (note: Triumph was a pre-dreadnought sunk later), as well as the French battleship Bouvet, primarily due to naval mines and shore artillery; mines laid by the Ottoman minelayer Nusret proved decisive. Notable engagements include the naval bombardment of fortifications, the 18 March 1915 failure of the fleet to break through the straits, and subsequent gunboat and destroyer actions supporting landings, convoy escorts, and evacuation operations.
Supporting operations encompassed commando-style raids, diversionary landings, and logistical missions such as the Helles landing, raids at Cape Helles and Gaba Tepe, and attacks by the Royal Naval Division on the peninsula flanks. French colonial detachments conducted operations at Kumkale and on the Asiatic shore opposite Eceabat, while ANZAC patrols and reconnaissance mapped Ottoman positions including Pieta Point and Walker’s Ridge. Special operations included submarine actions by Royal Navy Submarine Service boats in the Sea of Marmara, raids intended to interdict Ottoman shipping and communications, and engineering efforts to clear minefields and improve supply routes such as the Camel Corps-like logistics chains and field hospitals managed by the British Red Cross and Volunteer Aid Detachment units.
Principal Allied commanders included Ian Hamilton (Mediterranean Expeditionary Force), William Birdwood (ANZAC Corps), Aylmer Hunter-Weston (VIII Corps), and naval leaders such as John Fisher (First Sea Lord) and Rosslyn Wemyss. French leadership featured Henri Gouraud and naval commanders like Louis Dartige du Fournet. Ottoman leadership comprised Mustafa Kemal Atatürk (then Mustafa Kemal), Otto Liman von Sanders (German general), Esat Pasha, and regional commanders such as Said Halim Pasha. Forces included British Empire divisions, ANZAC brigades, French divisions, Territorial battalions, Ottoman XVI and V Corps, and supporting German advisory detachments as well as colonial troops from India and North Africa.
Casualties were heavy: Allied estimates vary but total Allied casualties (killed, wounded, missing) approached several hundred thousand, with Ottoman casualties also numbering in the hundreds of thousands; specific engagements such as Lone Pine and Chunuk Bair produced high rates among assaulting battalions. Ship losses included battleships and cruisers sunk by mines and artillery, notably the French battleship Bouvet and British pre-dreadnoughts; material losses included artillery pieces, small arms, ammunition, and transport vessels. Medical and sanitary strains led to outbreaks of dysentery, typhoid fever, and other diseases among wounded and garrison troops, treated in hospitals at Lemnos, Mudros, and shore installations including makeshift dressing stations at V Beach and W Beach.
The Allied evacuation completed by 9 January 1916 became a rare instance of an orderly withdrawal under fire, influencing later amphibious doctrine and lessons taught to planners of operations such as Operation Overlord and Gallipoli commemorations; politically the campaign affected careers of figures like Winston Churchill and prompted inquiries including the Dardanelles Commission. For the Ottoman Empire, the campaign bolstered national sentiment and elevated figures like Mustafa Kemal into prominence leading toward the Turkish War of Independence; for Australia and New Zealand the campaign catalyzed national consciousness commemorated annually on Anzac Day. Militarily, the campaign highlighted the interplay of naval power, fortification, mines, combined-arms coordination, logistics, and intelligence—lessons later examined by institutions such as the Royal United Services Institute and military historians like Cecil Aspinall-Oglander and Les Carlyon.
