[8] Fourth invasion in 1810 led due to Muzaffar Khan's refusal to pay tribute where Ranjit Singh captured the city and laid siege of the fort.

[9] Tired of demands of tributes, Nawab Muzaffar Khan decided to militarily resist by putting the fort in a state of defence after repairing the fort and mounting guns and gathering resources, and this led to Ranjit Singh's final conquest of Multan in 1818, resulting in the capture and fall of the city, bringing the territory under the complete domain of Sikh Empire with the appointment of Sukh Dayal Khatri as the governor of Multan followed by Sham Singh Peshauriya.

[10] In early 1818, Ranjit Singh ordered Misr Diwan Chand to rendezvous on the south-west frontier of the Sikh Empire to make preparations for an expedition against Multan.

[11] In early January, Misr Diwan Chand began their campaign with the capture of Nawab Muzaffar Khan's forts at Muzaffargarh and Khangarh.

The Sikh forces under Misr Diwan Chand won an engagement near the city but were unable to capture Muzaffar before he retreated into the fort.
