Darya Khan was killed in action in the Battle of Fatehpur when an arrow struck his throat, thus ending the reign of Jam Feroz as an independent ruler.
[citation needed] In the Mongol days, Sultan Hussain Mirza Baiqra, of Khurasan, responding to complaints of the Central Asian merchants of Herat and Qandhar that they had been looted by Sindhis, sent an armed expedition to the Sind border.
It stated that the infidels (Sindhis), aware of Mongol movements, collected a large army and planned a surprise attack.
Jam Nizamuddin died after 48 years of rule of Sind and was succeeded by his son Nasiruddin Abul Fatah Feroz Shah-II.
At that time, Jam Feroz had neglected affairs of state and refused the advice of Darya Khan, who retired to his Jagir in the village Ghaha (Kahan near Sehwan).
[5] Records of his last days include: Tahiri: that the courtiers being jealous of his power and position persuaded Feroz Shah to crush him, but the latter finding himself incapable avoided any direct conflict; so they approached Feroz's mother Madina Machhani advising her to invite the Mongols and Arghuns to free Sindh from the power of Darya Khan.
Darya Khan left Feroz Shah in the city and came out to fight a fierce battle, which he lost, and was captured by Tingari Birdi Qabtasal and put to sword along with the other Samma soldiers.
Beglar Namat:he was captured and killed.Zafar-ul-Walih: he was called by the Arghoons to discuss peace terms and treacherously murdered.The shrine of Dollah Darya Khan Sammo is in Makli graveyard in Thatta, near the grave of Jam Nizamuddin Samma.
