Ram Singh left Delhi on 27 December 1667 and finally reached Rangamati in February 1669. He was accompanied by Rashid Khan, ex-faujdar of Guwahati.

The Ahoms, anticipating a Mughal strike, are said to have followed his movements from Delhi itself.

Along the way Aurangzeb augmented Ram Singh's forces of 4,000 troopers (from his char-hazaari mansab), 1,500 ahadis (soldiers recruited by the Emperor) and 500 barqandezes by an additional 30,000 infantrymen, 21 Rajput chiefs (Thakurs) with their contingents, 18,000 cavalry, 2,000 archers and shieldmen and 40 ships.

When Lachit surveyed the massive Mughal force later, he was moved to tears and he uttered: "It is a tragedy that my country is facing this dire catastrophe during my Phukanship.

How will my king be saved? How will my people be saved? And how will my posterity be saved?". Armies from Koch Bihar joined the Mughal forces since they were vassals.
