In July Sir James, when Rottenberg came, sent Brock to Upper Canada and, in September, with his goods and chattels, chiefly consisting of books which, we have seen, he learned to love as a boy, he moved to Fort George, Niagara. He had not been there a month before he again felt restless and anxious to get back to some post where he might see service, for he expressed a desire to serve with the British forces who were then in Spain and Portugal. The adjutant-general, Colonel Baynes, however, replied that Sir James Craig informed him that he did not think the state of the public service would warrant his relieving Brock from duty in Upper Canada. Brock busied himself with the duties attendant on his position and seems to have spent a good deal of time, as he had done in Quebec, in trying to gain the confidence of the people. He early saw that the upper province was by no means restful and his suspicions of a few years ago that the American immigrants were unsettling the province were thus confirmed. In June, 1811, he was promoted to the rank of major-general. Sir James Craig, with the excuse of ill-health, resigned the position of governor-general and left for England. Sir James was ill, but he had incensed Lower Canada so much that his departure at this time was the best service he could render the country. Before he went he begged Brock to remain in Canada. “Your presence is needed here,” he said. And a little later, as an earnest of what the governor-general thought of him, Brock received a letter from Colonel Baynes in which he said: “He (Sir James) requests that you will do him the favor to accept as a legacy and mark of his very sincere regard his favorite horse Alfred, and he is induced to send him to you, not only from wishing to secure for his old favorite a kind and careful master, but from the conviction that the whole continent of America could not furnish you with so safe and excellent an horse?” Three months later Sir George Prevost, who was the new governor-general of and commander of the forces in Canada, appointed Brock president and administrator of the government of Upper Canada, in place of the lieutenant-governor who had obtained leave to visit England. Upper Canada needed him, and Sir George Prevost made a wise move in this appointment. Bad feeling between Britain generally and the United States had developed in connection with the Canadas.
