Veer Singh was awarded the title Jallaha (Duke) of Gurdaspore after his army single-handedly won the eastern areas of Punjab for the Maharaja.
Later when the Sikh Empire fell to the British forces, the armies of the Jallaha of Gurdaspore (then under the son of Veer Singh) were not defeated due to their strong defenses.
At an early age his family was forced out of Gurdaspore (now Gurdaspur a district in Punjab) after the Raja of Kapurthala attacked the rather peaceful town.
Later Veer Singh led his armies against the Raja, and won back Gurdaspore.
Dhillon participated in the following conquests: Sialkot, Kasur (1807), Multan (1818), Kashmir (1819), Pakhli & Damtaur (1821-2), and finally Gurdapore (1831).
