The Battle of Tippecanoe, upon which Harrison's fame was to rest, disrupted Tecumseh's confederacy but failed to diminish Indian raids. By the spring of 1812, they were again terrorizing the frontier.
In the War of 1812 Harrison won more military laurels when he was given the command of the Army in the Northwest with the rank of brigadier general. At the Battle of the Thames, north of Lake Erie, on October 5, 1813, he defeated the combined British and Indian forces, and killed Tecumseh. The Indians scattered, never again to offer serious resistance in what was then called the Northwest.
Thereafter Harrison returned to civilian life; the Whigs, in need of a national hero, nominated him for President in 1840. He won by a majority of less than 150,000, but swept the Electoral College, 234 to 60.
But before he had been in office a month, he caught a cold that developed into pneumonia. On April 4, 1841, he died--the first President to die in office -- and with him died the Whig program.
