Ahom rulers quietly funded rebellions in Mughal-controlled Kamarupa, sheltering dissidents, bankrolling chieftains, and arming hill tribes, all while maintaining a veneer of neutrality. When that veneer finally cracked in 1636, it cracked violently. King Pratap Singha assembled ten thousand soldiers, sixty warships, and a fleet of five hundred smaller vessels and sent them downriver to break Mughal control over the Brahmaputra's strategic crossings. The Battle of Sualkuchi was the centerpiece of a campaign that would reclaim an entire region.
