The Battle of Lundy's Lane, also known as the Battle of Niagara, occurred on July 25, 1814, during the War of 1812. It took place near present-day Niagara Falls, Ontario, and was one of the bloodiest battles of the war. The American forces, led by Major General Jacob Brown, were facing off against British and Canadian troops. The battle ended in a brutal stalemate, with heavy casualties on both sides, including approximately 258 killed and a total of about 1,720 casualties.

The battle saw several phases of intense fighting. Brigadier General Winfield Scott's American brigade clashed with British artillery, suffering heavy losses. However, Major Thomas Jesup's 25th U.S. Infantry managed to outflank the British and Canadian units, causing confusion and pushing them back. Later, Lieutenant Colonel James Miller's 21st U.S. Infantry made a daring bayonet charge, capturing British guns and driving the British center from the hill. British Lieutenant General Gordon Drummond mounted several counter-attacks, but they were repelled by the American forces.

By midnight, both sides were exhausted and severely depleted. American casualties were high, and Brown ordered a retreat to Fort Erie. The British, while still having a significant presence on the battlefield, were in no condition to interfere with the American withdrawal. The battle had strategic implications, as it forced the Americans to fall back and lose their initiative on the Niagara Peninsula. It was a hard-fought engagement with significant casualties, making it one of the deadliest battles fought in Canada during the War of 1812.
