Later, on March 24, 1843, Mir Sher Muhammad Khan Talpur, reached Hyderabad with his private army of around 8,000 soldiers and tried to recapture Sindh from the East India Company forces. He sent Napier a message giving the General forty-eight hours to vacate the Hyderabad Fort. Napier who was firmly entrenched in Hyderabad Fort and had recently been reinforced from Bombay replied by firing his artillery from the fort walls. Mir Sher Muhammad Khan Talpur was subsequently defeated in the Battle of Dubba and thereafter he went to Punjab to seek help from Maharaja Ranjeet Singh, the Sikh ruler of the Punjab. The Maharaja extended hospitality but declined to become involved. Sher Muhammad Khan then went to the Khan of Kalat to seek assistance, but the Khanate of Kalat had already suffered a defeat by the East India Company in 1838 and was in no position to help. Eventually after 10 years, Mir Sher Muhammad returned to Sindh and surrendered to the East India Company administration, which gave him amnesty.
