Timur himself recorded the invasions in his memoirs, collectively known as Tuzk-i-Timuri.[21] In them, he vividly described the massacre at Delhi:
In a short space of time all the people in the [New Delhi] fort were put to the sword, and in the course of one hour the heads of 10,000 infidels were cut off. The sword of Islam was washed in the blood of the infidels, and all the goods and effects, the treasure and the grain which for many a long year had been stored in the fort became the spoil of my soldiers. They set fire to the houses and reduced them to ashes, and they razed the buildings and the fort to the ground .... All these infidel Hindus were slain, their women and children, and their property and goods became the spoil of the victors. I proclaimed throughout the camp that every man who had infidel prisoners should put them to death, and whoever neglected to do so should himself be executed and his property given to the informer. When this order became known to the ghazis of Islam, they drew their swords and put their prisoners to death.
