The War of 1812 for The USA

In the War of 1812, the United States took on the greatest naval power in the world, Great Britain, in a conflict that would have an immense impact on the young country’s future. Causes of the war included British attempts to restrict U.S. trade, the Royal Navy’s impressment of American seamen and America’s desire to expand its territory. The United States suffered many costly defeats at the hands of British, Canadian and Native American troops over the course of the War of 1812, including the capture and burning of the nation’s capital, Washington, D.C. in August 1814. Nonetheless, American troops were able to repulse British invasions in New York, Baltimore and New Orleans, boosting national confidence and fostering a new spirit of patriotism. The ratification of the Treaty of Ghent on February 17, 1815, ended the war but left many of the most contentious questions unresolved. Nonetheless, many in the United States celebrated the War of 1812 as a second war of independence, beginning an era of partisan agreement and national pride.

At the outset of the 19th century, Great Britain was locked in a long and bitter conflict with Napoleon Bonaparte’s France. In an attempt to cut off supplies from reaching the enemy, both sides attempted to block the United States from trading with the other. In 1807, Britain passed the Orders in Council, which required neutral countries to obtain a license from its authorities before trading with France or French colonies. The Royal Navy also outraged Americans by its practice of impressment, or removing seamen from U.S. merchant vessels and forcing them to serve on behalf of the British. In 1809, the U.S. Congress repealed Thomas Jefferson’s unpopular Embargo Act, which by restricting trade had hurt Americans more than either Britain or France. Its replacement, the Non-Intercourse Act, specifically prohibited trade with Britain and France. It also proved ineffective, and in turn was replaced with a May 1810 bill stating that if either power dropped trade restrictions against the United States, Congress would in turn resume non-intercourse with the opposing power. After Napoleon hinted he would stop restrictions, President James Madison blocked all trade with Britain that November. Meanwhile, new members of Congress elected that year led by Henry Clay and John C. Calhoun–had begun to agitate for war, based on their indignation over British violations of maritime rights as well as Britain’s encouragement of Native American hostility against American expansion in the West.

In the fall of 1811, Indiana’s territorial governor William Henry Harrison led U.S. troops to victory in the Battle of Tippecanoe. The defeat convinced many Indians in the Northwest Territory (including the celebrated Shawnee chief Tecumseh) that they needed British support to prevent American settlers from pushing them further out of their lands. Meanwhile, by late 1811 the so-called “War Hawks” in Congress were putting more and more pressure on Madison, and on June 18, 1812, the president signed a declaration of war against Britain. Though Congress ultimately voted for war, both House and Senate were bitterly divided on the issue. Most Western and Southern congressmen supported war, while Federalists (especially New Englanders who relied heavily on trade with Britain) accused war advocates of using the excuse of maritime rights to promote their expansionist agenda.

In order to strike at Great Britain, U.S. forces almost immediately attacked Canada, then a British colony. American officials were overly optimistic about the invasion success, especially given how underprepared U.S. troops were at the time. On the other side, they faced a well-managed defense coordinated by Sir Isaac Brock, the British soldier and administrator in charge in Upper Canada. On August 16, 1812, the United States suffered a humiliating defeat after Brock and Tecumseh’s forces chased those led by Michigan William Hull across the Canadian border, scaring Hull into surrendering Detroit without any shots fired.
