He maintained friendly relations with the British and accompanied Lord Lake to the River Beas in pursuit of Jasvant Rao Holkar. He was deputed by the British General to persuade his nephew, Maharaja Ranjit Singh, not to espouse the hopeless Maratha cause. Bhag Singh`s mediation in behalf of the British helped pave the way for the first AngloSikh treaty of 1806. He gained in territory both from the British and Maharaja Ranjit Singh. Ludhiana, later acquired by the British for establishing a poltical agency, once belonged to him. Raja Bhag Singh died in 1819 and was succeeded by his son. Fateh Singh.
