The Bonus Army

'On July 28, 1932, protesters known as the "Bonus Army," or "Bonus Expeditionary Forces (B.E.F.)," who had gathered in the nation's capital to demand an immediate lump-sum payment of pension funds (benefits) for their military service during World War I, were confronted by Federal troops (cavalry, machine-gunners, and infantry) following President Herbert Hoover's orders to evacuate. (While Congress had approved the payment in 1924, the bonus was not payable until 1945.)The presence of the Bonus Army was a continuing embarrassment and source of difficulty for Hoover. He sent in troops under the command of Brigadier Perry L. Miles and General Douglas MacArthur. The veterans faced tear-gas bombs, bayonets, and tanks.' - Library of Congress
