After the French surrendered, Gage, A British General, was named military governor of Montreal. In 1761, he was promoted to major general and placed in command of the 22nd Regiment. When Amherst returned to England in August 1763, Gage assumed command of the British forces in America. Though the British were now at peace with France, Gage's new command inherited a Native American uprising already in progress on the western frontier.
In May 1763
Ottawa leader
Chief Pontiac's forces attacked Fort Detroit, in the first action of what would come to be known as
Pontiac's War.
Hoping to end the conflict diplomatically, Gage ordered Colonel
John Bradstreet and Colonel
Henry Bouquet out on military expeditions and then ordered
Sir William Johnson to establish peace negotiations. Colonel Bouquet negotiated a cease-fire of sorts in October 1764. Even then, Gage was left with just two remaining forts from the original nine the tribes had taken. In 1765, Gage finally got the 42nd
Royal Highland Regiment through to retake
Fort Cavendish.
Gage established a new three-district command across the western, southern, and northern areas of the frontier. That same summer, Gage ordered Johnson's office to send a representative through to Pontiac. The conflict would not be fully resolved until Pontiac himself travelled to
Fort Ontario and signed a formal treaty with Johnson in July 1766.
Gage's administration now saw a time of rising political tension throughout the American colonies.
Gage began withdrawing troops from the frontier to fortify urban centres like New York City and Boston. As the number of soldiers stationed in cities grew, the need to provide adequate food and housing for these troops became urgent.
Parliament passed the
Quartering Act of 1765, permitting British troops to be quartered in private residences. Gage personally traveled to Boston and spent six weeks there making quartering arrangements for the new soldiers in 1768. The military occupation of Boston eventually led to the
Boston Massacre of 1770. That same year, Gage was promoted to
lieutenant general. Late that year he wrote "America is a mere bully, from one end to the other, and the Bostonians by far the greatest bullies."
Gage and his family returned to England in June 1773 and missed the
Boston Tea Party in December of that year. The resulting controversy saw British forces shut down Boston Harbor until the colonists had made reparations in full for every leaf of tea lost.
Massachusetts governor
Thomas Hutchinson was 62 years old at the time and the lieutenant governor (
Andrew Oliver), a hated
Tory, was 67. Still in his early 50's and with plenty of military experience in America, Gage was deemed the best man to handle the brewing crisis.
In May of 1774, he was appointed
martial law Royal governor, or commander-in-chief, of Massachusetts, replacing the civilian governor. In that capacity, he was entrusted with carrying into effect the
Boston Port Act. General Gage strictly enforced the confiscation of war-making materials.
In September 1774, he carried out a mission to seize the gunpowder of
Somerville, Massachusetts. Gage successfully accomplished this mission but was not successful in other raids. This was in large part due to
Paul Revere and the
Sons of Liberty. The Sons of Liberty kept careful watch over Gage's activities after this point and successfully warned future insurgents before Gage could mobilise his
lobsterbacks against them.
Gage found himself criticised by his own men for allowing groups like the Sons of Liberty to exist. One of his officers,
Hugh Percy remarked, "The general's great lenity and moderation serve only to make them (the Americans) more daring and insolent." Gage himself wrote, "If force is to be used at length, it must be a considerable one, and foreign troops must be hired, for to begin with small numbers will encourage resistance, and not terrify; and will in the end cost more blood and treasure."
Edmund Burke described Gage's conflicted relationship by saying in
Parliament, "An Englishman is the unfittest person on Earth to argue another Englishman into slavery.
