After the establishment of British forces in the south of Iran, units under the title of South Persia Rifles were established in several southern cities of Iran, including Kazerun. Naser Divan Kazeruni was very unhappy about this and finally declared war on them. He said to the people of Kazerun: Naser Divan, along with some of his riflemen, attacked the South Persia Rifles headquarters in Kazerun and disarmed them, and then arrested Amir Nosrat Nuri, the then governor of Kazerun. Kazeruni forces were able to close the mountain communication road from Shiraz to Bushehr port, which lasted for 3 years. No matter what the British forces stationed in Bushehr tried, they failed to open this road. On 28 December 1916, five hundred soldiers under the command of the British went from Shiraz to Kazerun to suppress him. But before the British forces reached Kazerun, the fighters of Kazerun blocked the way in the
Dasht-e Arzhan area and inflicted a heavy defeat on them. In this battle, Captain Vetikogol, one of the British officials, was also killed. The British decided to send an army from Bushehr to suppress the Kazerunis. But this corps was also besieged by Sheikh Hossein Khan Chah Kutahi and Zair Khezr Khan Ahrami in
Chah Kutah area before reaching Kazerun, some of them were killed and some fled towards Bushehr. == Siege of Shiraz ==
