Apart from the War of Independence do you mean?

The US Civil War.

Most wars are fought with help from other countries. Are you trying to be incendiary, or are you sincere in this question?

A country doesn't win a Civil War, part of it does. Now... nope. Can't. The Barbary War?

The Spanish American War. Cuban and Phillappine nationals may have played a contributory roll but at the time they were not recognized as nations. For that matter the Mexican American War as well.

The War on people who think that stupid mental diseases should not be in the DSM-IV.

"The War of 1812 (in Britain, the American War of 1812, to distinguish from the war with Napoleon I of France) was fought between the United States of America and the United Kingdom and its colonies, especially Upper Canada (Ontario), Lower Canada (Quebec), Nova Scotia, and Bermuda. When the war had finished, 1,600 British and 2,260 American troops had died. The war was fought from 1812 to 1815 and involved both land and naval engagements. Britain was at war with France and, to impede American trade with France, imposed a series of restrictions that the U.S. contested as illegal under international law. The Americans declared war on Britain on June 18, 1812 for a combination of reasons: outrage at the impressment (conscription) of thousands of American sailors into the British navy, frustration at British restraints on neutral trade, and anger at alleged British military support for American Indians defending their tribal lands from encroaching American settlers." Source and further information: http://en.wikipedia.org/wiki/War_of_1812 "The United States had faced near disaster in 1814, but the victories at the Battle of New Orleans and the Battle of Baltimore and what seemed to be a successful fight against the United Kingdom increased national patriotism and helped to unite the United States into one nation. The best-known patriotic legacy of the war was The Star Spangled Banner. The words are by Francis Scott Key who after the bombardment of Fort McHenry set them to the music of a British song, "To Anacreon in Heaven." In 1889 the U.S. Navy began using The Star Spangled Banner at flag-raising ceremonies, a practice copied by the army. In 1931, Congress made it the U.S. national anthem. The principal gain for the United States was a renewed self-confidence and faith in the ability of its military to defend the nation's freedom and honor. Although neither side came away from the war with a clear-cut victory, the American people saw the War of 1812 as evidence of the success of the democratic experiment. The war ushered in a period of American history that has frequently been called "the Era of Good Feelings," a time when, at least on the surface, most Americans felt unified behind a common purpose. The War of 1812 convinced the country that it could fend off any foreign threats and that its focus should be on expansion at home."
