During the Great Depression, over 17,000 veterans of the First World War marched on Washington to demand payment for their service. Known as the Bonus Army, they set up camp in a Hooverville in Anacostia Park. The marchers remained at their campsite waiting for President Herbert Hoover to take action after Congress rejected a bill to pay the veterans. On July 28, 1932, Attorney General William D. Mitchell ordered the Metropolitan Police to remove the Bonus Army veterans from their camp. When the veterans moved back into it, they rushed two officers trapped on the second floor of a structure. The cornered officers drew their revolvers and shot two veterans, William Hushka and Eric Carlson, who died later. In the aftermath of the shooting, President Hoover ordered the military, under General Douglas MacArthur, to disperse the Bonus Army. Fifty-five veterans were injured and 135 arrested.
