Sikh leaders then sought the original partition instead, and the Congress Working Committee passed a resolution in support of partitioning Punjab and Bengal. Between March and August 1947, a series of riots, arson, plunder of Sikh and property, assassination of Sikh leaders, and killings in Jhelum districts, Rawalpindi, Attock and other places led to Tara Singh calling the situation in Punjab a "civil war", while Lord Mountbatten stated "civil war preparations were going on". The riots had triggered the early waves of migration in April, with some 20,000 people leaving northwest Punjab and moving to Patiala. In Rawalpindi, 40,000 people became homeless. The Sikh leaders made desperate petitions, but all religious communities were suffering in the political turmoil. Sikhs, states Banga, were "only 4 million out of a total of 28 million in Punjab, and 6 million out of nearly 400 million in India; they did not constitute the majority, not even in a single district". When the partition line was formally announced in August 1947, the violence was unprecedented, with Sikhs being one of the most affected religious community both in terms of deaths, as well as property loss, injury, trauma and disruption. Sikhs and Muslims were both victims and perpetrators of retaliatory violence against each other. Estimates range between 200,000 and 2 million deaths of Sikhs, Hindus and Muslims. There were numerous rapes of and mass suicides by Sikh women, they being taken captives, their rescues and above all a mass exodus of Sikhs from newly created Pakistan into newly independent India. The partition created the "largest foot convoy of refugees recorded in [human] history, stretching over 100 kilometer long", states Banga, with nearly 300,000 people consisting of mostly "distraught, suffering, injured and angry Sikhs". Sikh and Hindu refugees from Pakistan flooded into India, Muslim refugees from India flooded into Pakistan, each into their new homeland. Khalistan In 1940, a few Sikhs such as the victims of Komagata Maru in Canada proposed the idea of Khalistan as a buffer state between an independent India and what would become Pakistan. These leaders, however, were largely ignored. The early 1980s witnessed some Sikh groups seeking an independent nation named Khalistan carved out from India and Pakistan. The Golden Temple and Akal Takht were occupied by various militant groups in 1982. These included the Dharam Yudh Morcha led by Jarnail Singh Bhindranwale, the Babbar Khalsa, the AISSF and the National Council
