Third Anglo-Afghan War

The Third Anglo-Afghan War began when Amanullah Khan, the new emir of Afghanistan, sent troops across the frontier into British India in the aftermath of the First World War, in an attempt to end British control of Afghanistan's foreign affairs. The Afghan forces crossed at the Khyber Pass and elsewhere, while British and Indian troops, though tired after the world war, pushed them back. The Royal Air Force bombed Kabul and Jalalabad, an early use of air power against cities in the region. An armistice was agreed after about a month, and the Treaty of Rawalpindi confirmed Afghanistan's independence in its foreign affairs. Afghans celebrate their independence day to mark the result.
