When Mirza Taqi Khan, Grand Vizier of Nasiri’d-Din Shah, found he was unable to exterminate the Bábí Faith, he determined to put The Báb to death. The Báb was taken to Tabriz and the Armenian regiment of Uramayyih, commanded by the Christian colonel Sam Khan, was ordered to carry out the execution. When the smoke cleared after the 750 rifles had fired, The Báb was nowhere to be seen and His companion, Mirza Muhammad ‘Ali, was standing unharmed. The bullets had only cut the ropes that bound them. The Báb was, after a brief search, found in the room He had occupied the night before, continuing the conversation with His amanuensis that had been interrupted earlier. Sam Khan refused to carry out the execution a second time and ordered his regiment to leave the barracks. The colonel of the bodyguard, Aqa Jan Khan-i-Khamsih, volunteered to carry out the order and this time the bullets of his regiment killed The Báb. The Commemoration of the Martyrdom of The Báb is observed at noon on July 9th. Work is suspended on this Holy Day.
