The Fall of Kabul took place in 2001 during the Afghanistan War. Northern Alliance forces began their attack on the city on November 13, and made swift progress against Taliban forces that were heavily weakened by American and British air strikes. The advance moved ahead of plans, and the next day the Northern Alliance forces entered Kabul and met no resistance inside the city. Taliban forces retreated to Kandahar in the south. Coupled with the fall of Mazar-i-Sharif five days earlier, the capture of Kabul was a significant blow to Taliban control of Afghanistan.
