The Americans declared war on Britain (the War of 1812) to uphold American honor at sea, and to end the Indian raids in the west, as well as to temporarily seize Canadian territory as a negotiating chip. Secretary of State James Monroe said in June 1812, "It might be necessary to invade Canada, not as an object of the war but to bring it to a satisfactory conclusion." Despite incompetent government management, and a series of defeats early on, Americans found new generals like Andrew Jackson, William Henry Harrison, and Winfield Scott, who repulsed British invasions and broke the alliance between the British and the Indians that held up settlement of the Old Northwest. The Federalists, who had opposed the war to the point of trading with the enemy and threatening secession, were devastated by the triumphant ending of the war. The remaining Indians east of the Mississippi were kept on reservations or moved via the Trail of Tears to reservations in what later became Oklahoma.
