Why did the USA invade Canada in 1812? The United States invaded Canada as part of its war against Britain. Some Americans hoped to make Canada part of the United States, while others believed that conquering it would force Britain to negotiate. Either way, they expected a much easier victory than they actually achieved.
In 1812, Britain and the USA were at war. Britain was also at war with Napoleon’s France. The United States had declared war on Britain on 18 June 1812. They had several reasons for wanting to go to war. The first was that Britain was preventing America from trading with France. In order to bring the war in Europe to a close as fast as they could, Britain tried to cut off all trade with France. That meant turning back American ships. The problem was, America was an independent country and felt that it had the right to trade with whichever country it chose. The second reason was that Britain was stealing sailors off the American vessels and forcing them to join the British Navy, a process called impressment or press-ganging. The third reason was that Britain was trying to prevent American expansion westward by helping the indigenous people. Britain wanted to protect the fur trade, hold back the Americans, and keep a buffer zone between the United States and Britain’s territories in Canada. Britain offered some concessions and had already decided to repeal some of its trade restrictions, but news traveled so slowly across the Atlantic that the decision reached America too late to prevent the declaration of war..
About a month after declaring war, American forces headed north for Canada. The United States had little chance of defeating the powerful British Navy, so American leaders decided to attack Britain’s territory on land instead. They hoped that capturing Canada would force Britain to negotiate. Some also wanted to take the territory permanently, removing British influence from northern North America. Because Canada had such a small population, only 600,000 compared to almost 8 million in the USA, people like Thomas Jefferson thought it would just be a case of marching in. Many of the inhabitants of Canada used to be Americans, and they thought many Canadians would welcome them as liberators. However, that is not what happened.
The American army marched across the Detroit River into Upper Canada in July of 1812. They ended up retreating, and they lost the fort at Detroit. They crossed again in October, but they had to turn back again. In 1813, they managed to get further, and they captured York (now Toronto) and burned the government buildings. They won victories on Lake Erie and at the Battle of the Thames, but that was as far as they could get, and they realized they wouldn’t be able to control Canada. Their attempt to capture Montreal failed in late 1813, and although fighting continued in 1814, American forces never succeeded in conquering Canada.
So, why couldn’t the American army take control of Canada? There were several reasons. The American army was not as well prepared as it could have been. The USA had a relatively small standing army at the time, and many of the soldiers were inexperienced. Some of the commanders were elderly or ineffective. The British forces were better trained than the Americans had thought they would be. The USA thought Britain would have saved all of its capable soldiers for the fight in Europe, but they still had experienced professional soldiers stationed in Canada. These troops were generally better trained than the inexperienced American forces. The Americans were also hindered because when they crossed into Canada, a lot of the soldiers refused to go. They thought their job was to defend their own states and not invade another country. However, the two biggest things that stood against their invasion were the size of Canada and the Canadians and indigenous people. Canada is an enormous country, and the forests, rivers, lakes, and severe winters made supplying the American soldiers extremely difficult. They also expected to be welcomed into Canada as liberators. Many Canadians had no desire to join the United States. Some were descendants of Loyalists who had left America during or after the Revolutionary War because they wanted to remain under British rule. Others were French-speaking Canadians who had their own reasons for resisting American control. They were not sympathetic to America’s cause. The indigenous people also feared what America would do if they managed to capture the territory, so they fought as well. Their knowledge of the region allowed them to disrupt American operations, which could sometimes sway a whole battle.
The United States had underestimated both the difficulty of invading Canada and the determination of the people defending it. In 1814, Britain and America began negotiating an end to the war. The Treaty of Ghent was signed in December 1814, and the war officially ended in February 1815. Neither country gained any territory, and Canada remained under British control. Although there would be further disputes and raids along the border, Britain and the United States would never fight another war against each other. And this is what I learned today.
