In June 1753,
Hendrick Theyanoguin and a delegation of Mohawk traveled to New York City, where they announced to Governor Clinton that the
Covenant Chain—the diplomatic relationship between the British and the Iroquois—was broken. The British government ordered Clinton to convene the
Albany Congress of 1754 to repair the Covenant Chain. At the Congress, the Mohawk insisted that the alliance would be restored only if Johnson were reinstated as their agent. Johnson's reinstatement as Indian agent came the following year, just as the
French and Indian War, the North American theater of the
Seven Years' War, was escalating. In 1755, Major General
Edward Braddock, sent to North America to direct the British war effort, turned to Johnson for assistance in obtaining Native scouts. Although Johnson had little military experience, he was commissioned as a
major general and instructed to lead an expedition against the
French fort at
Crown Point. His troops were provincial soldiers paid for by the colonies, rather than regular soldiers of the
British Army, which meant that he had to deal with six different colonial governments while organizing the expedition. Tensions escalated as the two generals worked against each other in recruiting Native allies. The dispute was complicated by the unusual command structure: as Braddock's second-in-command, General Shirley was Johnson's superior officer, but when it came to Indian affairs, Johnson was theoretically in charge. In time, Shirley would blame the failure of his expedition on Johnson's refusal to provide him with adequate Indian support. According to the Johnson biographer Milton Hamilton, historians usually portrayed Johnson as acting unreasonably in the controversy with Shirley, but Hamilton argued that Johnson was simply reacting to Shirley's clumsy Indian diplomacy, which harmed the British relationship with the Six Nations.
Crown Point expedition Marching north into French territory, in August 1755 Johnson renamed Lac du Saint-Sacrement to
Lake George in honour of his king. On 8 September 1755, Johnson's forces held their ground in the
Battle of Lake George. Johnson was wounded by a ball that was to remain in his hip or thigh for the rest of his life.
Hendrick Theyanoguin, Johnson's Mohawk ally, was killed in the battle, and
Baron Dieskau, the French commander, was captured. Johnson prevented the Mohawk from killing the wounded Dieskau, an act memorialized in later paintings of the event. '' by
Benjamin West The battle ended the expedition against Crown Point. Johnson built
Fort William Henry at Lake George to strengthen British defences. In December, tired of army life, Johnson resigned his generalship. General Shirley, who had become the commander-in-chief upon Braddock's death, sought to have Johnson's commission as Indian agent modified, forcing Johnson to work for him directly. This attempt at retaliation was foiled when Shirley was unexpectedly removed from office and recalled to England. Although the Battle of Lake George was hardly a decisive victory, the British needed a military hero in a year of major setbacks, and Johnson became that man. Claims that Johnson had been disabled by his wound early in the battle, and thus did not participate in the victory, did not reduce the recognition given to him. As a reward for his services, Parliament voted Johnson £5,000 and
King George made him a
baronet. In January 1756, the British government made Johnson sole
Superintendent of Indian Affairs for the northern colonies. This position gave him great influence and power, since he would report directly to the government in London and would not be controlled by provincial governments. Of all the Indian nations in the northern colonies, Johnson was most knowledgeable about, and most closely connected to, the Iroquois Six Nations, especially the Mohawk. As superintendent, he would make the Iroquois the focus of British diplomacy, promoting and even exaggerating the power of the Iroquois Confederacy. Johnson also began a long process of seeking to dominate the Confederacy's diplomatic and political administration, attempting "nothing less than the refurbishment of the Iroquois confederacy with himself as to its centre".
Capture of Fort Niagara Although Johnson was no longer a British general, he continued to lead Iroquois and frontier militia. In August 1757, after the French began their
siege of Fort William Henry, Johnson arrived at
Fort Edward with 180 Indians and 1,500 militia. Greatly overestimating the size of the French army, British General
Daniel Webb decided against sending a relief force from Fort Edward to Fort William Henry. The British were compelled to surrender Fort William Henry, after which many were killed in an infamous massacre. Stories circulated that Johnson was enraged by Webb's decision not to send help, and that he stripped naked in front of Webb to express his disgust. With the war going badly for the British, Johnson found it difficult to enlist the support of the Six Nations, who were not eager to join a losing cause. In July 1758, he managed to raise 450 warriors to take part in a massive expedition led by the new British commander, General
James Abercrombie. The campaign ended ingloriously with Abercrombie's disastrous attempt to
take Fort Carillon from the French. Johnson and his Indian auxiliaries could do little as British forces stormed the French positions in fruitless frontal assaults. 's iconic painting
The Death of General Wolfe, although he was not present at the event. In 1758, with the capture of
Louisbourg,
Fort Frontenac, and
Fort Duquesne, the war's momentum began to shift in favour of the British. Johnson was able to recruit more Iroquois warriors. In the summer of 1759, he led nearly 1,000 Iroquois warriors—practically the entire military strength of the Six Nations—as part of General
John Prideaux's expedition to
capture Fort Niagara. When Prideaux was killed, Johnson took command. He captured the fort after ambushing and defeating a French relief force at the
Battle of La Belle-Famille. Johnson is usually credited with leading or at least planning this ambush, but the historian
Francis Jennings argued that Johnson was not present at the battle, and that he exaggerated his role in official dispatches. Johnson commanded the "largest Native American force ever assembled under the British flag." Johnson accompanied General
Jeffery Amherst in the final North American campaign of the
Seven Years' War, the
capture of Montreal in 1760. With the fall of
New France to the British, Johnson and his deputy
George Croghan spent much time negotiating with the former Indian allies of the French. In 1761, Johnson made a 1,000-mile (1,600 km) round trip to Detroit to hold a conference with the regional American Indians. Johnson confronted the assembled chiefs about the anti-British rumours that were circulating among the Natives, and managed, for the time being, to forestall outright resistance to the British military occupation of the West.
Normand Macleod met Johnson at this conference and returned with him to New York. Macleod was later appointed as commander of
Fort Oswego, on Lake Ontario. ==British Superintendent of Indian Affairs==
