How a quest to protect oil supplies turned into a tragic Mesopotamian disaster
In short: During the First World War, Britain sent troops to Mesopotamia to secure vital oil assets. What began as a strategic defense evolved into a grueling, multi-year campaign marked by harsh climates, supply shortages, and the catastrophic siege of Kut, ultimately reshaping the map of the Middle East forever.
The Mesopotamian campaign began in 1914 when Britain deployed Indian divisions to protect oil interests in the Ottoman province of Iraq. Initially, the objective was limited to safeguarding refineries and pipelines essential for the Royal Navy’s oil-fired fleet. However, the mission soon expanded as British commanders, notably General Sir John Nixon, pushed for an ambitious offensive to capture Baghdad, hoping to rally Arab support against the Ottoman Turks.
The advance faced severe logistical failures. By late 1915, Major-General Charles Townshend’s 6th (Poona) Indian Division had pushed deep into the interior, reaching Kut by September. Yet, the force was dangerously overextended, lacking sufficient artillery, ammunition, and supplies. After a bloody repulse at Ctesiphon in November 1915, Townshend retreated to Kut, where his 10,000 troops and 3,500 camp followers were besieged by Ottoman forces. The subsequent starvation of the garrison, which lasted until their surrender in 1916, became a defining tragedy of the front.
Relief efforts, including the deployment of the Tigris Corps under Lieutenant-General Sir Fenton Aylmer, struggled against difficult terrain and poor coordination. Battles at Shaik Saad in January 1916 saw British forces hampered by mist, a lack of elevated ground, and intense enemy shrapnel fire. Despite these early setbacks and the loss at Kut, the British eventually reorganized, launching a renewed campaign that finally captured Baghdad in March 1917. The conflict concluded with the 1918 Armistice of Mudros, leaving the region under British mandate and setting the stage for the political volatility of the post-war era.
