Canada was now, for a space of two and a half years, to be involved in war, and subjected to the miseries of invasion. It was a war with which she had no proper concern. The measures adopted by England and France in order to accomplish the ruin of each other fell injuriously upon American commerce, and the American people were reasonably displeased that their occupations and those of the world should be interrupted by the strifes of two unwisely guided nations. Certain high-handed proceedings of British ships[18] so aggravated this irritation, that America declared war against Great Britain. She had no quarrel with the Canadians, but she could not elsewhere express the hostile impulses by which she was now animated. An invasion of Canada was instantly resolved upon, and an easy victory was expected. The country was almost undefended, for England at that time was putting forth her utmost strength in the effort to overthrow Napoleon, and she required, for the bloody battle-fields of Spain, every soldier of whom she could possess herself. In all Canada there were only four thousand regular troops and two thousand militiamen. Many weeks must elapse before help could come from England. Canada had grown steadily during forty years of peace, and had now a population of three hundred thousand. But the progress of the United States had been greatly more rapid, and Canada had now to encounter a hostile nation of eight million. The expectation that the Americans would subdue and possess the valley of the St. Lawrence seemed easy of fulfilment. Many Americans clung to the belief that the Canadians were dissatisfied with their government, and would be found ready to avail themselves of an opportunity to adopt republican institutions. But no trace of any such disposition manifested itself. The colonists were tenaciously loyal, and were no more moved by the blandishments than they were by the arms of their republican invaders. [Sidenote: July, 1812 A.D.] Soon after the declaration of war, an American army of two thousand five hundred men set out to conquer Western Canada. The commander of this force was General Hull, who announced to the Canadians that he had come to bring them “peace, liberty, and security,” and was able to overbear with ease any resistance which it was in their power to offer. But victory did not attach herself to the standards of General Hull. The English commander, General Brock, was able to hold the Americans in check, and to furnish General Hull with reasons for withdrawing his troops from Canada and taking up position at Detroit. Thither he was quickly followed by the daring Englishman, leading a force of seven hundred soldiers and militia and six hundred Indians. He was proceeding to attack General Hull, but that irresolute warrior averted the danger by an ignominious capitulation.
