The History of Shāhjahān (ʿInāyat Khān) 23: Siege of Kandahar raised.

23

Ultimately the duration of the siege extended beyond five months, the winter began to set in, all the lead, powder, and cannon-balls were expended, and neither was there any forage left in the meadows, nor provisions with the army. Farman likewise was issued to this effect, that as the winter was close at hand, and they had already been long detained in Kandahar, if the reduction of the fortress could not be effected just at once, they might stay if necessary some short time longer ; or otherwise return immediately. Rustam Khan, who had been recalled from Bust for the purpose of sharing in the assault, having dismantled that fortress, distributed the provisions among his men, and reached Kandahar with his comrades, bringing all the artillery stores, and property in the Kar-khana, that was there, along with him. With an eye therefore to the safety of the property mentioned above, he deemed it expedient to return, and not one of the royalist commanders proposed staying any longer. The Prince Buland Ikbal consequently, on the 15th Zi-l ka'da this year, set out from Kandahar for Hindustan.
