The Sikhs often passing through a series of vicissitudes, first establish themselves as a political power in the Punjab in 1765 A.D. But their mode of fighting then was desultory and hardly suited to the requirements of a well-settled state, However Maharaja Ranjit Singh 'Built up a strong , centralized and effectively controlled military system by amalgamating the best elements in foreign with best elements found in the indigenous fighting mechanisms. Hari Singh Nalua's significant military campaign was that of Kasur, the so called 'mythological rival of Lahore', in 1807 A.D. Hari Singh Nalua along with Sardar Jodh Singh Ramgarhia, Sardar Nihal Singh Attari, Baba Akali Phula Singh, Fateh Singh Ahluwalia, Dhanna Singh Malwai, and Sardar Fateh Singh Kalianwala marched on to Kasur to subjugate its Afghani owner Kutab-ud-din Khan. Sikhs laid siege for three months after which Kutab-ud-din Khan surrendered. Hari Singh Nalua, of course, was the first to march inside the city gate of Kasur with his division called 'Sher-Dil-Rajman.' The troops under him caught Kutab-Ud-Din alive and presented him before Maharaja Ranjit Singh. Maharaja Ranjit Singh made him retire to a territory of Mamdot as a jagir, subject to his supplying 100 horsemen for service when required.
