American veterans of World War I returned home to promises of bonuses but faced hard times during the Great Depression as the bonuses were not to be paid until 1945. Thousands of desperate veterans traveled to Washington D.C. to demand early payment, setting up camps. When Congress rejected early payment, President Hoover ordered the camps cleared. General MacArthur led cavalry to destroy the camps, and clashes left several dead and hundreds wounded, undermining support for Hoover months before the 1932 election.
