Dilbagh Singh Minhas of Jallandhar Doab.

It has very beautiful parks for the public. It has many plant nurseries selling a variety of beautiful plants. It also hosts a flower show every year.

It is one of the oldest cantonments in India, established in 1848 after the first Anglo-Sikh War, when the British settled in Northern India. The original scope of this cantonment was limited to troops to quell disturbances from adjoining States for the maintenance of peace and order.

In 1920 the cantonment was the scene of mutiny by Irish soldiers, who were protesting against martial law in Ireland by refusing to obey orders. They took down the Union Flag and replaced it with the flag of the Irish Republic, proclaimed at the time in Dublin (See The Connaught Rangers#Mutiny in India, 1920).

The departure of British from India and subsequent partition of the country changed the complexion of the Cantonment. It has gained tremendous importance on account of its nearness to the border with Pakistan.

Military Hospital Jalandhar was established here to provide health care and education to troops of the Indian army and their families. It is the peacetime station and family station for the 163 Medium Artillery Regiment, 169 Field Artillery Regiment, 141 Air Defence (SAM) Regiment, 4th Battalion Rajputana Rifles, 4th Battalion of Bengal Sappers and 2nd Signals Battalion. The families of soldiers and officers of the above units live in the cantonment housing.
