Third Anglo-Afghan War: The 1919 Struggle for Independence
The Third Anglo-Afghan War, known in Afghanistan as the War of Liberation, was a brief but pivotal conflict that took place between May 3 and August 8, 1919. This clash pitted the Emirate of Afghanistan against the United Kingdom and British India along the volatile North-West Frontier. While the military engagements were short-lived, the political ramifications were profound, ultimately altering the sovereignty of the Afghan nation.
The conflict was ignited by the new Emir, Amanullah Khan, who sought to proclaim full independence and solidify his legitimacy by declaring a Jihad (holy war) against British influence. Taking advantage of widespread unrest within India, Afghan forces launched an invasion on three fronts, aiming to reclaim ancestral provinces west of the Indus River.

Historical Background: The Great Game
The roots of the 1919 conflict lay in the Great Game, a strategic rivalry between the British Empire and Tsarist Russia. Britain viewed Afghanistan as a critical buffer zone, fearing that Russian influence in Kabul could lead to an invasion of India. This anxiety fueled two previous conflicts: the First Anglo-Afghan War (1839–1842) and the Second Anglo-Afghan War (1878–1880).
Following the Second Afghan War, the Treaty of Gandamak (1879) effectively gave Britain control over Afghan foreign policy, stipulating that Afghanistan should have "no windows looking on the outside world, except towards India." Although this was not strictly enforced, the tension between nominal independence and British oversight persisted for decades.
The catalyst for the Third War arrived after World War I. Influenced by a Turko-German mission, Emir Habibullah Khan began asserting Afghanistan's independence. He requested a seat at the 1919 Versailles Peace Conference, but was denied by the British viceroy, Lord Chelmsford. Following Habibullah's assassination on February 19, 1919, his successor, Amanullah Khan, moved decisively toward total sovereignty.
Military Operations and the Role of Airpower
The Afghan invasion was characterized by bold movements across the frontier, but the British responded with a combination of traditional infantry and emerging technology. The British and Indian forces utilized a variety of artillery, including 18-pounders, 4.5-inch howitzers, and mountain guns, though many batteries were under-strength.
A significant turning point occurred at Stonehenge Ridge. After a preliminary bombardment, the 11th Sikh Regiment launched an assault. Despite delays caused by ammunition shortages and extreme heat, the Sikh forces eventually seized the ridge, finding that the Afghan forces had retreated, leaving behind artillery and standards. British and Indian forces suffered 22 killed and 157 wounded, while Afghan losses were estimated at 200 killed and 400 wounded.
The most decisive factor in the conflict was the introduction of British airpower. The Royal Air Force (RAF) conducted bombing raids on Kabul, including a strike on the Amir's palace on May 24, 1919. This aerial campaign severely damaged Afghan morale and pressured Amanullah Khan to seek an armistice.
Outcome and Political Resolution
An armistice was signed on June 3, 1919, followed by peace negotiations in Rawalpindi. Although the British had successfully evicted Afghan forces from Indian soil, the political climate forced them to make significant concessions. The resulting treaty granted Afghanistan the right to conduct its own foreign affairs and establish embassies abroad without British mediation.

Military Honors
British and Indian infantry units that served in the conflict were awarded the battle honour "Afghanistan 1919."

This honor was granted across various orders to British units, Indian Army Corps, Indian States Forces, and Gurkha regiments.
