"The inter-religious violence that occurred in Jammu and Kashmir against the backdrop of the 1947 Partition of India and its aftermaths included a possible ‘ethnic cleansing’ of Jammu’s Muslims. One million Kashmiri Muslim refugees were uprooted and an estimated 2,500,00-300,000 were massacred in the Jammu region alone in August-October 1947. Violence was directed in the main by the Dogra Hindu state troopers aimed at driving them out from fear of death. Despite the grwoing concerns of the ‘new history’ of Partition, until recently it has been dominated by the Punjab experience of violence and mass migration. This has been to the detriment of other regions such as Jammu which experienced a similar pattern of disruption, one that was equally profound."

From journalist Ved Bhasin's article
The worse happened in the Jammu city where the Muslim localities of Talab Khatikan and Mohalla Ustad were virtually besieged and the Muslims were even denied water supply and food-grains. In the lower parts of the city Lakhdata Bazar and Peer Mitha Bazar were the dividing lines between Hindus and Muslims. Most of the Muslims outside the Muslim dominated areas were brutally killed by the communal marauders who moved freely in vehicles with arms and ammunition even when the city was officially put under curfew. The curfew, it appeared, was meant only to check the movement of Muslims. Some of us managed to carry some food-grains for besieged Muslim friends and others in Mohalla Ustad. Though Colonel Pir Mohammed and some other royalists had put up white peace flags on their houses the communalists made many efforts to attack them.
Hindus had taken up positions on their houses situated at the border line of Lakhadata Bazar and Peer Mitha. They were later joined by the troops from Patiala. The Muslims in Talab Khatikan area too had joined to defend themselves with whatever arms they could gather. Some reinforcement was provided to them by the Muslim Conference later.
There was mass killing of Muslims in and around Jammu. A large number of Gujjar men and women who used to supply milk to the city from the surrounding villages were massacred en-route. The Ramnagar rakh was littered with the dead bodies of Gujjar men, women and children. A colleague of mine, while on his morning walk in Ramnagar area, heard the shrieks of a child and found an 8-9 year old girl crying along with the slain bodies of her parents in Ramangar rakh.
The worst carnage took place later when the Muslims in Talab Khatikan area were asked to surrender. They were shifted to the police lines at Jogi Gate, where now Delhi Public School is situated. Instead of providing them security, the administration encouraged them to go to Pakistan for their safety. The first batch of several thousand Muslims were loaded in about sixty lorries to take them to Sialkot. Unaware of what is going to happen to them these families boarded the buses. The vehicles were escorted by the troops. But when they reached near Chattha on Jammu-Sialkot road, in the outskirt of the city, a large number of armed RSS men and Sikh refugees were positioned there. They were pulled out of the vehicles and killed mercilessly with the soldiers either joining them or looking as idle spectators. The news about the massacre was kept a closely guarded secret.
Next day another batch of these Muslim families were similarly boarded in the vehicles and met the same fate. Some of those who somehow managed to escape the wrath of killers reached Sialkot to narrate their tales of woes and sorrow.
On Mirpur, journalist Ved Bhasin writes
The communal violence that gripped Jammu was not altogether one-sided. A large number of Hindu and Sikhs too were butchered in some parts of the region, particularly in Rajouri, Mirpur and areas now under Pakistan. In Rajouri while Hindus from the neighbouring
Muslim dominated villages shifted to the town, the Muslims from the town migrated to the nearby villages or even crossed over to the other side. The Muslim gangs surrounded the town later and resorted to mass killings, loot and rapes. Similarly a large number of Hindus were killed in Mirpur district. While the Muslims from the district town of Mirpur migrated to the nearby villages and even to Jhelum, the Hindus from the villages started trekking to the town for safety.
