The entire Hindu and Sikh population of nine million in the Western districts of Punjab was brutally made to move to East Punjab. The same brutality happened to most of the Muslims living in Eastern Punjab, too. The flood of displaced Hindus and Sikhs was borne by the cities of Ferozepore and Amritsar. Most of the displaced Hindus and Sikhs, hailing from Sialkot district, crossed over to Gurdaspur, Kapurthala and Hoshiarpur, via Amritsar or Dera Baba Nanak. The refugees from Lahore tehsil took the Grand Trunk Road route between Lahore and Amritsar. But the mostly rural Hindu and Sikh refugees from Kasur and Chunian tehsils of Lahore district took the Kasur-Ferozepore route to cross over into the Indian Punjab.
