This is an accepted version of this pageThe Battle of Kafir Qala (Persian: نبرد کافر قلعه, romanized: Nabard-e Kāfir Qal'ah) was fought in June 1818 between Iran and the Durrani Empire.

The Iranians had captured Herat in 1816 but were forced to abandon it when the Afghans resisted the occupation of the city with an intense guerrilla war on the countryside.

The Iranians marched from Khorasan and met the Afghan army shortly after crossing the border in the town of Kafir Qala.

Although the exact numbers are debatable, all sources agree that the Durrani forces outnumbered the Qajars more than 2 to 1.

[2] The flank of the right wing included Husayn Qoli Khan Bayat Nishapuri with the infantry of Khorasan.
