This occurred on 3 October 1921 when Pessian and his small force of 150 gendarmes faced a force of strong 1,000 plus mounted Kurdish tribesmen. In the fight that ensued some of the Gendarmes left the battle field. Many of Pessian’s comrades were killed and he was eventually surrounded and beheaded. His head was brought to capital to prove that he had been killed. For five continuous years after his death, on 3 October people of Khorasan mourned his death.
In 1920 Mohammad Taqi returned and joined the Gendarmerie. In June 1920 he was promoted to the rank of colonel and in September 1920 he became commander of Gendarmerie of Khorasan. On 3 April 1921 in a military coup with his small force of only 200 gendarmes, he had Ahmad Qavam, the Governor-general of Khorasan, arrested and sent him to capital where he was imprisoned. He then became head of the provincial Autonomous Government of Khorasan. In June, Ahmad Qavam was released from prison and became Premier of homeland.
