The Americans' greatest military victory, ironically achieved after the War of 1812 had officially ended, was a. Andrew Jackson's defeat of a British invasion of New Orleans. b. Edward Packenham's invasion of England in 1815. c. William Henry Harrison's triumph over Creeks and British agents at Horseshoe Bend. d. Winfield Scott's victory over Tecumseh and British allies at Tippecanoe Creek.

The correct answer is A. The Americans' greatest military victory, ironically achieved after the War of 1812 had officially ended, was Andrew Jackson's defeat of a British invasion of New Orleans.

Explanation:

The Battle of New Orleans between the United States and Great Britain, which took place between December 23, 1814 and January 8, 1815, was the greatest battle of the War of 1812.

In late 1814 a British fleet of more than 50 ships sent by General Edward Pakenham, sailed into the Gulf of Mexico and prepared to attack New Orleans. The American general Andrew Jackson, commander of the American army that was in the southwest of the country, had his regiment composed mainly of militiamen and volunteers, with whom he fought against the British who suddenly attacked his position on January 8, 1815. The troops of Jackson effectively entrenched themselves behind the fortifications, while the English hosts were exposed, the fight being brief and ending in a decisive victory for the Americans, thus achieving British withdrawal and the death of General Pakenham.

The battle can be considered extemporaneous since the Treaty of Ghent that ended the war had been signed last December, but the report had been slow to arrive. The victory however raised national morale, improving Jackson's reputation to the level of a hero, which served as a platform for his path to the presidency.
