Lundy's Lane, Battle of, July 25, 1814, the hardest-fought land battle of the War of 1812. It took place in Canada, just west of Niagara Falls. Neither side won, but in effect it was a British victory because it halted the advance of United States troops into Canada.

In an effort to win control of Lake Ontario, United States forces crossed the Niagara River into Canada in the summer of 1814. They won a battle on July 5 at Chippewa. Three weeks later 1,200 United States troops under General Winfield Scott unexpectedly came upon a larger British force under General Phineas Riall on Lundy's Lane. Scott seized the initiative and attacked, while General Jacob J. Brown brought 1,700 more American troops. Then General Gordon Drummond arrived with more British troops, equalizing the armies. They fought until midnight, when the exhausted United States forces withdrew to Fort Erie. The British, also exhausted, did not pursue them.

The United States lost 853 men killed, wounded, and captured; the British force, 878. Scott, Brown, and Drummond were wounded and Riall was captured.
