The Mussalman invaders sacked the Buddhist universities of Nalanda, Vikramshila, Jagaddala, Odantapuri to name only a few. They razed to the ground Buddhist monasteries with which the country was studded. The monks fled away in thousands to Nepal, Tibet and other places outside India. A very large number were killed outright by the Muslim commanders. How the Buddhist priesthood perished by the sword of the Muslim invaders has been recorded by the Muslim historians themselves. Summarizing the evidence relating to the slaughter of the Buddhist Monks perpetrated by the Musalman General in the course of his invasion of Bihar in 1197 AD, Mr. Vincent Smith says, "The Musalman General, who had already made his name a terror by repeated plundering expeditions in Bihar, seized the capital by a daring stroke... Great quantities of plunder were obtained, and the slaughter of the 'shaven headed Brahmans', that is to say the Buddhist monks, was so thoroughly completed, that when the victor sought for someone capable of explaining the contents of the books in the libraries of the monasteries, not a living man could be found who was able to read them. 'It was discovered,' we are told, 'that the whole of that fortress and city was a college, and in the Hindi tongue they call a college Bihar.' "Such was the slaughter of the Buddhist priesthood perpetrated by the Islamic invaders. The axe was struck at the very root. For by killing the Buddhist priesthood, Islam killed Buddhism. This was the greatest disaster that befell the religion of the Buddha in India....

Khilji’s starring role in the destruction of Indian Buddhism is well-documented in contemporaneous Muslim sources and cannot be shifted to unnamed Hindu bogeys so cavalierly.
