Egyptian Expeditionary Force was a British-led military formation created in 1916 to conduct Ottoman Empire campaigns in Egypt and the Levant. It coordinated forces drawn from the British Army, Indian Army, Australian Imperial Force, New Zealand Expeditionary Force, Australian Light Horse, and Imperial Camel Corps for operations that culminated in the capture of Jerusalem and the defeat of Ottoman forces in Syria. The formation operated amid concurrent strategic interests involving France, Italy, Russia, and Arab Revolt actors such as Sharif Hussein bin Ali and T. E. Lawrence.

Formation and Organization

The force was formed under directives from War Office and Field Marshal Herbert Kitchener, reorganizing garrison troops in Egypt to secure the Suez Canal and project power into Palestine and Syria. Initial structure grouped formations into corps and divisions incorporating units from the British Empire and Dominion of Canada contingents; command posts liaised with British Government ministries and diplomatic missions in Cairo and Constantinople via military governors like Sir Reginald Wingate. Organizational doctrine blended lessons from the Gallipoli Campaign, Western Front logistics, and mounted warfare traditions from Second Boer War veterans.

Early command was vested in General Archibald Murray who implemented defensive preparations around the Suez Canal and prepared offensive operations such as the Sinai and Palestine Campaign. In 1917 command transferred to General Edmund Allenby, whose leadership emphasized combined arms coordination among infantry, cavalry, artillery, and air components including the Royal Flying Corps. Allenby worked with political figures including David Lloyd George, military staff like Henry Wilson, and regional allies such as Emir Faisal and Hashemite forces. Key subordinate commanders included Harry Chauvel of the Anzac Mounted Division and Philip Chetwode of cavalry formations.

The force conducted actions across the Sinai Peninsula and Palestine Campaign, including battles at Romani, Magdhaba, Rafah, Gaza, Beersheba, and Jerusalem. After the failed first and second Battle of Gaza, tactics evolved leading to success at the third Battle of Gaza and the breakthrough at Beersheba followed by the capture of Jaffa and Haifa. In 1918 EEF advanced north through Syria, engaging Ottoman armies at Megiddo and contributing to the collapse of Ottoman authority in the Levant, intersecting with political outcomes like the Sykes–Picot Agreement and the Armistice of Mudros. Operations integrated naval bombardment from Royal Navy squadrons and air reconnaissance by the Royal Air Force precursor units.

Composition included regular British Army divisions, territorial units, Indian Army brigades, and Dominion contingents: Australian Imperial Force infantry divisions, New Zealand Expeditionary Force brigades, and ANZAC Mounted Division cavalry. Specialized formations comprised the Imperial Camel Corps, Egyptian Labour Corps, artillery brigades equipped with 60-pounder and 18-pounder guns, and logistical units from the Royal Army Service Corps and Egyptian Army auxiliaries. Cavalry elements included the Yeomanry regiments and mounted brigades under commanders such as Edward Chaytor. Signals and medical support drew on organizations like the Royal Army Medical Corps and Royal Engineers.

Sustaining operations required maritime supply via Mediterranean Sea convoys to Alexandria, rail construction across the Sinai including the Railway to El Arish, water pipeline projects supplying wells and the Suez Canal hinterland, and coordination with local infrastructure managers in Cairo and Alexandria. Logistics involved coordination with the War Office transport committees, use of camel corps transport, and medical evacuation to base hospitals run by the Queen Alexandra's Imperial Military Nursing Service. Intelligence and reconnaissance used cavalry patrolling, signals intercepts, and aerial photography developed by the Royal Flying Corps.

The force’s campaigns reshaped postwar mandates in the League of Nations era, influencing the establishment of British Mandate for Palestine and French Mandate for Syria and Lebanon. Military lessons informed interwar doctrine on combined arms, desert warfare, and imperial expeditionary logistics; notable veterans influenced later institutions including the British Indian Army reorganization and Australian Defence Force traditions. The EEF’s actions intersected with nationalist movements led by figures such as Mustafa Kemal Atatürk and Faisal I of Iraq, and contributed to the geopolitical reordering formalized by treaties like Treaty of Sèvres and the armistices ending Ottoman participation in World War I.
