Final answer:
After the Battle of Baltimore, the Treaty of Ghent was negotiated and signed in Ghent, Belgium, in December 1814, ending the War of 1812 and maintaining the pre-war boundaries between the US and British Canada.
Step-by-step explanation:
Just after the Battle of Baltimore during the War of 1812, diplomats from Britain and the United States met in Ghent, Belgium, to negotiate the Treaty of Ghent. This significant treaty was signed in December 1814, effectively ending the war between the two nations. It stipulated that the pre-war boundaries should remain, thus preserving the territorial status quo for both the United States and British Canada.
This result was particularly welcome to Americans who had feared the impact of the war on the country's expansion westward. The treaty's signing preceded the Battle of New Orleans, which was fought after the treaty had been signed due to a delay in communication over the Atlantic. Even the British commander in New Orleans, Lambert, planned further campaigns until he received news of the Treaty of Ghent and declared the cessation of hostilities.
