With the coup succeeding, Hotak assembled the inhabitants of Kandahar and made a speech about how the loss of George had weakened Persia, and the opportunity for freedom and liberty was now available to Afghans. Mirwais said: Every Afghan hearing the speech felt inspired to defend the liberty granted to them. Hotak then assembled leading men of the different tribes and presented the situation to them: the Persians would likely send a punitive expedition. Hotak was given complete executive power, armed his forces, and spread word of his successes to other tribes to encourage them to join the revolt. On the fourth day after George's death, the rest of the Georgian dispatch returned from their campaign to suppress the Tarins, numbering around 600 disciplined Georgian men. Hotak allowed them to approach within range of musket shot fire, then directed the guns to open up on the Georgian army. He opened up another gate with over 5,000 cavalrymen to cut off the Georgian retreat; 600 Georgians managed to breach through the cavalry. Hotak pursued the Georgian army for days; though repelled, he inflicted heavy casualties on them. The retreating Georgians carried news of the revolution at Kandahar. The Persian court tried to solve the issue diplomatically due to fear of the Hotaks calling in the
Mughal Empire. They sent an ambassador, Jani Khan, to assure Hotak that George's death would be forgiven if they allowed a Persian garrison in Kandahar. Hotak imprisoned him to stall for time and delay Persia's preparations by refusing to answer the court. After hearing nothing from Jani Khan, the Persian court sent another ambassador, Muhammad Khan, to Kandahar. He was informed that he should "never make base proposals to men who are free". When the ambassador returned, the Persian court realized that war was the only option to subdue Hotak and his followers.
Clashes with the Persian army In 1710, the Persians dispatched a force under Muhammad Khan to go to Kandahar and quell the rebellion. Hotak, hearing that the army was mostly made up of
Persians, advanced with over 5,000 cavalrymen and defeated the Persian army. Over 18 months, the Persians dispatched four more armies, but each was defeated. On the last attempt, the Persians advanced with over 5,000 men, commanded by Mahammad Khan, and was repelled by the 500-man Afghan army, with the Persians suffering over 1,000 killed and wounded. Amongst the prisoners from the battle was Mahammad Khan and his three sons. In the wake of these defeats, the Persian court focused all the imperial resources of the Persian empire on Hotak. George's nephew Khusru Khan marched with a large Persian army to Kandahar against Hotak. Khusru scouted ahead after advancing to
Farah, and Mirwais took positions near Ghirisk on the banks of the
Helmand River, leaving the passes unguarded. Khusru led his army of 42,000 through the pass where he met Hotak and his army. The Afghans, inferior in numbers, were defeated by Khusru, and with this victory, Khusru marched on to Kandahar. He demanded that Kandahar surrender to him, but the Afghans resisted. Hotak hastened to the south of Kandahar and mobilized a force of
Balochs and Tarins to march toward Kandahar. He cut off enemy supply lines, laid waste to the land around Kandahar, and threatened enemy communications. Khusru tried to prolong the siege as long as he could, but he lost two-thirds of his force to scorched earth tactics and enemy counterattacks. Khusru called for a retreat, but Hotak advanced. The Persian army was destroyed and Khusru was killed.
Subsequent Persian failed expeditions In late 1712, the
qorchibashi (head of the mounted cavalry or royal guards) Mohammad Zaman Khan was entrusted with the task of attacking the Afghans whilst assembling an army en route. However, the lack of funds greatly hindered his expedition. Rather than using money from his own treasury, Soltan Hoseyn forced the merchants in Isfahan and
New Jolfa to give a combined amount of 14,000
tomans. The expedition eventually fell apart when Zaman Khan died near Herat in the spring of 1712. He was succeeded by Mansur Khan Shahsevan, whose expedition also ended in failure. He left Isfahan in September 1713 with fifty troops and more or less without any funds. Meanwhile, Sultan Husayn had forced his courtiers to lend him money to construct a new
maydan (town square) in
Farahabad. During the summer of 1713, 500 soldiers were marching towards the east, with no funds and horses and equipped with sticks. Mahd Ali Khan, who governed
Farah, was unable to march towards with his 1,500 soldiers towards Mirwais due to lack of funds. Many of his soldiers had deserted and made the countryside dangerous. ==Death and legacy==
