As regards the situation in Lahore, Gurbachan Singh Talib presents graphic details in several pages of many instances of killing, burning and looting by Muslims. Allegedly Nawab Iftikhar Hussain Mamdot, Sardar Shaukat Hayat, Mian Iftikharuddin, Begum Shahnawaz and other Muslim leaders directed the attacks on the Sikhs and Hindus in Lahore. Further, that the predominantly Muslim administration aided and abetted the attackers. Among them Magistrate G.M. Cheema was the most notorious.

On the 10th August almost all Hindu and Sikh localities were set on fire. Fires were raging in Chune Mandi, Bazaz Hatta, Sua Bazar, Lohari Gate, Mohalla Sathan and Mozang. Everywhere the police led the attacks on non-Muslim areas.
Non-Muslim tried to escape from this burning inferno. But all outlets were closed to them. On the 11th August at least 500 people were killed, while trying to escape from Lahore with their lives. In the streets, on the roads, and especially at the Railway Station they were killed in hundreds. Muslim goondas, Muslim National Guards and the Baluch Military who were part of the Boundary Force, all participated in this slaughter with zeal and gusto. The only non-Muslim evacuees who escaped killing on this day, were those who either by good luck or through someone’s help managed to reach the Lahore Cantonment Railway Station. These got into the trains reaching Ferozepore, and thus saved their lives. That was because there were Sikh soldiers in, the Cantonment area, and so Muslim aggression could not be free there. Lahore main station was completely in the grip of Muslim troops and police. Harrowed, miserable Hindu and Sikh refugees from Lahore began to be in evidence in towns of the East Punjab as far off as Ambala by the 13th August. . They came completely destitute, hungry and with a haunting terror of death at the hands of Muslims in their eyes.
Other areas which were set on fire on August 12 and 13 were: Bharat Nagar, Singhpura, Dabbi Bazar, Lohari Gate, Gali Hingaran, Gali Kagzian, Kucha Chah Telian etc. In all these areas and many others non-Muslims were killed not in hundreds, but in thousands.
The famous historic Sikh Gurdwara of Chhevin Padshahi, situated at a distance of fifteen yards from the Police Station on Temple Road in Mozang, was set on fire on the morning of the 15th August. The few Sikhs who were inside the Gurdwara were burnt alive in the flames.
This was one of the numerous places of non-Muslim worship which had been burned in Lahore. Baoli Sahib, Gurdwara Chaumala Sahib and others had been burned before. Even the famous Dehra Sahib, held in highest sanctity by the Sikhs as being the place of martydom of Sri Guru Arjan Dev, fifth Guru of the Sikhs, was attacked. The Sikh guards and priests of this Gurdwara were mostly killed. Such money and valuables as were there, were looted by the Muslim police and military stationed in the Lahore Fort which is at a distance of a few yards from the Gurdwara.
In these days Lahore railway platforms presented the picture of a shambles. Such Hindus and Sikhs as managed to reach the railway station were shot down in heaps. Regular chase was given by the Muslim goondas to the unfortunate men, women and children who tried to escape with their lives.
The destruction of Lahore and of its non-Muslim inhabitants would have been complete but for the presence in the city of Dogra troops, but they were soon shifted from Lahore. It was only in the Cantonment that non-Muslims could find some safety, as Sikh troops were present there.
