Kafirs in Jalalabad and had honoured them with gifts. Timurids The campaigns of Timur are recorded by Zafarnama, written by Sharaf ad-Din Ali Yazdi, which is based on another work. On his way to India, Timur attacked the Siyah-Posh in 1398 AD after receiving complaints from the trading city of Andarab about the raids by the Kafirs. He penetrated Kafiristan from Khawak pass and restored an old fortress there. He personally proceeded against the Kator region, which extended from Kabul to Kashmir. Timur sent a detachment of 10,000 soldiers against the Siyah-Poshas under Burhan Aglan and had the fort of Kator deserted by Kafirs destroyed, while the houses of the city were burnt. The Kafirs took refuge on top of a hill and many were killed in the ensuing clash. Some held out for three days but agreed to convert after Timur offered them the choice between death and Islam. They however soon apostatised and ambushed Muslim soldiers in the night. They Muslims repelled them and a number of the Kafirs were killed, with 150 being taken prisoner and later executed. Timur ordered his men "to kill all the men, to make prisoners of women and children, and to plunder and lay waste all their property." His soldiers carried out the order and he directed them to build a tower of skulls of the dead Kafirs. Timur had his expedition engraved on a neighbouring hill in the month of Ramadan. His detachment sent against the Siyah-Poshas however met with disaster, with Aglan being routed and forced to flee. A small detachment of 400 men under Muhammad Azad was then sent and defeated the Kafirs, retrieving the horses and armour Aglan lost. Timur later captured a few more places, though nothing more is stated, presumably he left the Siyah-Poshas alone. He proceeded to exterminate the rebellious Afghan tribes and crossed the Indus River in September 1398. The Timurid Sultan Mahmud Mirza is said to have raided Kafiristan twice by Baburnama, which earned him the title of ghazi. Yarkand Khanate Mirza Muhammad Haidar Dughlat invaded Balor under orders of Sultan Said Khan in 1527-1528 AD, and was accompanied by Said's eldest son Rashid Khan. The expedition was an Islamic frontier raid called ghaza. Dughlat undertook highly devastating plundering raids against the region. Rashid Khan (r. 1533–1569) undertook further expeditions against Bolor (Kafiristan), which are recorded by Tarikh-i-Kashgar and Bahr al-asar of Mahmud
