A Shoushi liberation operation 24 years ago proved a landmark in liberation of Nagorno-Karabakh.

The battle of Shoushi took place on May 8, 1992, and the town was liberated on May 9. Azerbaijani troops had until that time shelled the capital of Nagorno-Karabakh, Stepanakert.

The operation was launched in four directions. The Armenian forces established control over the Qirs positions and Lachin-Shoushi highway.

The operation plan was worked out under the command of Arkadi Ter-Tadevosyan, during March-April, 1992, and was based on the intelligence data.

The Armenian forces launched an offensive along a 25-km-long line, and reached the Armenian border on May 18.
