The same happened to sikhs in Pakistan.. but muslims suffered more bcoz Pakistan had sikhs in minority... while indian side of punjab had much more muslims.. motivated by whom.. the first train to arrive in Pakistan had only 1 survivor a baby in the arms of his dead mother...
From the boundry of Delhi to the banks of Ravi River the population is divided as follows: Muslims, 4,505,000; Sikhs and other non-muslims, 7,060,000. To this may be added the population of Sikh states of Patiala, Nabha, Jind, Kapurthala and Faridkot, which is about 2,600,000, of this Muslims constitute barely 20 percent and this reduces the ratio of Muslim population still further. We shall resist by all possible means, separation of Punjab from the all-India union. We shall never permit our motherland to be at the mercy of those who disown it. After it was a certainity that Pakistan will be formed, Giani Kartar Singh in 1943 declared a call for a Separate state called Azad Punjab, to be comprised of Ambala, Jullundar, Lahore, Multan, and Lyallpur divisions. Mastar Tara Singh president of SAD and other Sikh leaders such as Giani Sher Singh, Sadhu Singh Hamdard,Amar singh Dosanjh, Ajit singh Ambalvi supported this call for Azad Punjab. Then in a speech in Amritsar in August 1944, Master Tara Singh declared that Sikhs were a nation and as such a demand was formerly put forward by Shiromani Akali Dal in a resolution passed on March 22, 1946 for a separate Sikh state. After this situation in Punjab was getting tense. On one hand Jinnah and Muslim league was calling for blood or Pakistan and declaring that Muslims are no believer of ahimsa and will resort to any means possible to achieve their means. Muslim league declared August 16th 1946 to be observed as Direct Action Day, where all muslims were asked to show the support for Pakistan by rioting. Explaining the implications of Direct Action Day threat, Liaqat Ali Khan, general secretary of Muslim league said "Direct action means resort to non-constitutional methods that can take any form which many suit the conditions under which we live. We cannot eliminate any methods. Direct Action means any action against the law." Sardar Abdur Rab Nishtar spoke in more forthright terms: "Pakistan can be achieved through shedding blood of others. Muslims are no believers in ahimsa.
The decree of violence and jingoism was enthusiastically embraced by the Muslim masses. The Muslim league created a private army called Muslim National Guards. Arms were being secretely amassed, petrol stored and lethel weapons laid in. Muslim league volunteers were especially trained in the skills of stabbing and fire-raising. Simultaneously, a chorus of hate and inflammatory exhortation flowed from the League pulpiteers and newspapers. Communal frenzy was worked up to a dangerous pitch and on appointed day the storm burst in Calcutta. H.S. Suhrawardy, Muslim league leader from Bengal let loose horron on the Hindu population on the morning of August 16 1946. Stabbing, looting, burning were the order of the day. For four days the League desperados had the city at their mercy. According to rough estimated about 15,000 persons were killed and injured while one hundred thousands were rendered homeless. Then on 2nd September in Noakhali and Tippera (Bengal) where Hindus were in minority, violence broke out. Thousands of Hindus were cruelly murdered, their womenfolks abducted and compelled to marry Muslims, property looted. The Sikhs of Calcutta did a notable humanitarium job at the time of the Great killing, saving many innocent lives in Hindus as well as in Muslim localities. Soon violence spread northwards. According to Muslim league, the Sikhs were the only viable obstruction to Pakistan. Justice G.D. Khosla of the Fact Finding Organization setup by Government of India observed: "Sikhs had opposed the partition of India with even greater vigour than Hindus, because they felt that as a community they could only expect disaster in Pakistan, therefore it was against the Sikhs that spearpoint of the Muslim league attack was first aimed. In the March 1947 riots, the Sikhs or Rawalpindi faced ahhihilation and large number of them left the district. Within a few weeks almost the entire Sikh population had migrated from the district. Rioting in Punjab started in first week of December in the district of Hazara. A Holy war was declared on Hindus and Sikhs. Sikh habitations were wiped out, Gurdwaras were desecrated. Rioting in Lahore was started in March 4 1947, it started out as stabbing and small incidents and spread out to become arson and murder. Soon after Muslims in Amritsar (muslims were about 40-50% of population before partition) went rioting, a mob tried to attack Golden Temple and were repulsed with a pitched battle fought between handful of Sikhs under Jathedar Udham Singh Nagoke. Same day muslims of Sharifpura (a suburb of Amristar), stopped a train full of refugees from Pakistan for slaughter. After this incident, Sikhs and Hindus in Amritsar were furious and many innocent muslims had to bear the fury of anger. Soon after Amritsar was empty of Muslims. While total number of casualties were about same on both sides, about 100-150 million refugees were exchanged between both countries. There were large number of atrocities inflicted on women, many were abducted and raped. In village Thoh Khalsa (now in Pakistan), 1000 Sikh and Hindu women jumped into well to save their honor after their menfolks were killed by Muslim mobs. It is estimated that about 1 million Hindus/Sikhs/Muslims were murdered and 10-50 millions were injured. Property lost was in trillion of dollars.
Muslims did got their Pakistan but soon after it was put under marshall law by its feudal infested army. Sikhs did themselves a big favour by opting out of Pakistan at this time in Pakistan situation of few Hindus/Christians/other muslims (shia, Ahmadias) is worse off then in any other country. Judges are often asked to hang a non-muslims only on the basis of accusation. Sikh leadership opted for India and millions of Sikhs migrated to East Punjab and Delhi. Recently a well known bishop of a church shot himself on the door steps of a court in Pakistan after another christian was sentenced to death after a false accusation.
