On 18 April 1848, Kahan Singh and Vans Agnew arrived at Multan with another officer, Lieutenant William Anderson, and a small escort. Mulraj handed over the keys of the fortress, but as Vans Agnew's party attempted to take possession, they were attacked by a party of Mulraj's irregular troops, and a mob from the city. Both officers were wounded, and were rescued by Kahan Singh. They were taken to a mosque outside the city. Their escorts defected to Mulraj, and the two officers were murdered by the mob the next day.
