The United States was also not prepared for war. Madison had assumed that the state militias would easily seize Canada and that negotiations would follow. In 1812, the regular army consisted of fewer than 12,000 men. Congress authorized the expansion of the army to 35,000 men, but the service was voluntary and unpopular; it paid poorly and there were initially few trained and experienced officers. The militia objected to serving outside their home states, they were undisciplined and performed poorly against British forces when called upon to fight in unfamiliar territory. Multiple militia refused orders to cross the border and fight on Canadian soil. American prosecution of the war suffered from its unpopularity, especially in New England where anti-war speakers were vocal. Massachusetts Congressmen Ebenezer Seaver and William Widgery were "publicly insulted and hissed" in Boston while a mob seized Plymouth's Chief Justice Charles Turner on 3 August 1812 "and kicked [him] through the town". The United States had great difficulty financing its war. It had disbanded its national bank, and private bankers in the Northeast were opposed to the war, but it obtained financing from London-based Barings Bank to cover overseas bond obligations. New England failed to provide militia units or financial support, which was a serious blow, and New England states made loud threats to secede as evidenced by the Hartford Convention. Britain exploited these divisions, opting to not blockade the ports of New England for much of the war and encouraging smuggling. War in the West Invasions of Canada, 1812 An American army commanded by William Hull invaded Upper Canada on July 12, arriving at Sandwich (Windsor, Ontario) after crossing the Detroit River. His forces were chiefly composed of untrained and ill-disciplined militiamen. Hull issued a proclamation ordering all British subjects to surrender, or "the horrors, and calamities of war will stalk before you". The proclamation said that Hull wanted to free them from the "tyranny" of Great Britain, giving them the liberty, security, and wealth that his own country enjoyed—unless they preferred "war, slavery and destruction". He also threatened to kill any British soldier caught fighting alongside indigenous fighters. Hull's proclamation only helped to stiffen resistance to the American attacks as he lacked artillery and supplies. Hull also had to fight just to maintain his own lines of communication. Hull withdrew to the American side of the river on 7 August 1812 after receiving news of
