Occasion
The British Government decided to reinstate Shah Shuja, who was a refugee in British territory, Dost Mahommed being in power at Kabul.
Course of the War
A British Indian force advanced in March 1838, and entered Kandahar. Shah Shuja was crowned. Dost Mahommed withdrew, and Kabul was entered. The war was brought to an end, but in November 1841 a revolt broke out in Kabul and there were serious massacres. The British garrison in withdrawing was overwhelmed between Kabul and Jalalabad. Reinforcements, in 1842, forced the Kyber Pass, relieved Jalalabad and occupied Kabul. The army finally evacuated Afghanistan in December 1842.
