The Book of Akbar (Shaykh Ilāhdād Faiḍī Sirhindī) 7.2.4

On their return, they reported that they had never seen in any country a fort like this; for however long an army might press the siege, nothing but the extraordinary good fortune of the Emperor could effect its capture. Old soldiers, and men who had travelled into distant lands,—men who had seen the fortresses of Iran and Turan, of Rum, Europe, and of the whole habitable world, had never beheld the equal of this. It is situated on a high and strong hill, and three smaller hills, each having a fort, stand around it, like a halo round the moon. The ways of entrance and exit were difficult to discover. Near it there was no other hill commanding it, and no way of approach. All around was level ground, and there were no trees or jungle to serve as cover. All the time the country had been held by the dynasty, each prince, as he succeeded, did his best to keep the place in repair, to add to its strength, or to increase its stores. It was impossible to conceive a stronger fortress, or one more amply supplied with artillery, warlike stores, and provisions. There were 500 mans of opium, Akbar-shahi weight, in its stores. Were the fortress placed upon level ground, its reduction would be difficult; but such a hill, such a well-secured fortress, and such artillery, were not to be found in any one place on the face of the earth. After the capture of the fortress accounts were taken of the munitions.
