In 1777, two companies of the 34th Foot, including Ross's
grenadier company, were assigned to the
Saratoga campaign, an attempt by British forces under Lieutenant General
John Burgoyne to gain control of the
Hudson River valley. Ross was wounded at the
Battle of Hubbardton on 7 July 1777 and invalided back to Quebec. As a result, he escaped becoming a
prisoner of war when Burgoyne surrendered following the
Battles of Saratoga. In July 1780, Ross, a “veteran officer of high reputation,” was
brevetted major by the Governor of Quebec, Lieutenant General
Frederick Haldimand, and tasked with organizing the 2nd Battalion of the
King's Royal Regiment of New York. The King's Royal Regiment of New York was a provincial regiment composed of Loyalist volunteers. Initially, the 2nd Battalion was sent to
Coteau-du-Lac west of
Montreal, but in November 1780, were assigned to garrison Fort Haldimand, located on
Carleton Island at the head of the
St. Lawrence River. In October 1781, Ross led a large-scale raid that destroyed Warrensborough on the
Mohawk River east of
Fort Hunter. Ross arrived at
Oswego on
Lake Ontario on 3 October with 155 members of the 2nd Battalion, Leake's Independent Company, a company of the 34th Foot, a detachment of the
Royal Highland Emigrants, and a small number of Hanau
Jägers. A week later, Captain
Walter Butler arrived from
Fort Niagara with 150 Butler's Rangers and a detachment of the
8th Regiment of Foot. Also with the expedition were 100 Native Americans under the direction of Captain Gilbert Tice of the
British Indian Department and
Mohawk war chief
David Hill. Ross subsequently allowed a number of prisoners to escape. The prisoners had been falsely told that the British intended to head west. Based on this false intelligence, Willett proceeded to Stone Arabia but after several hours waiting for Ross to appear realized he had been deceived. On 28 October, his scouts discovered Ross's trail. Willett set out in pursuit with 400 troops and 60
Oneida warriors. On 30 October, his vanguard encountered Ross's rearguard at
West Canada Creek. Butler was killed during the ensuing skirmish, most likely by an Oneida Indian. Willett decided to discontinue the pursuit. Ross continued north and returned to Carleton Island on 6 November. In the spring of 1782, Ross reestablished the British outpost at Oswego and rebuilt
Fort Ontario which had been abandoned years earlier. Ross was commended by Haldimand for the "rapid establishment of the post." ==Cataraqui settlement==
