He was a brave and skilful soldier and took part in almost every campaign undertaken by the Maharaja during his early career. He fought against Ghulam Muhammad Khan Chattha and against Jodh Singh of Wazirabad. He was with the Maharaja at the time of the capture of the city of Lahore in 1799. He participated in the Kasur (1801) and Jhang (1806) campaigns. Fateh Singh conquered Chiniot from Jassa Singh Bhangi and, when Jhang was taken in 1806 from Ahmad Khan Sial, the district was leased to him.
When towards the close of 1806, Qutb ud-Din Khan of Kasur raised the banner of revolt, Fateh Singh Kalianvala was sent against him. In 1807, Ranjit Singh, after a visit to Patiala, besieged the fort of Naraingarh held by Sardar Kishan Singh. Fateh Singh, who was in immediate command, assaulted the fort, but was repulsed and mortally wounded. He died on 25 October 1807.
