The Battle of the Somme was one of the largest battles of World War I, and among the bloodiest in all of human history.

The Vietnam War (1955-1975) is a black-marked event in the histories of both Vietnam and the United States, and one when the latter country, after losing thousands of soldiers in the war, was effectively badly defeated and forced to retreat.
The major wars fought on American soil are - the Seven Years War (Britain and France), the Revolutionary War and the War of 1812 (both Britain and USA), the Mexican American War, the Civil War and World War 2 on Hawaii and two Alaskan Islands.
