The Bonus Army was the popular name of an assemblage of some 43,000 marchers—17,000 World War I veterans, their families, and affiliated groups—who gathered in Washington, D.C., in the spring and summer of 1932 ...
Retired Marine Corps Major General Smedley Butler, one of the most popular military figures of the time, visited their camp to back the effort and encourage them. On July 28, U.S. Attorney General William D. Mitchell ordered the veterans removed from all government property. Washington police met with resistance, shots were fired and two veterans were wounded and later died. Veterans were also shot dead at other locations during the demonstration. President Herbert Hoover then ordered the army to clear the veterans' campsite. Army Chief of Staff General Douglas MacArthur commanded the infantry and cavalry supported by six tanks. The Bonus Army marchers with their wives and children were driven out, and their shelters and belongings burned.

At 4:45 p.m., commanded by Gen. Douglas MacArthur, the 12th Infantry Regiment, Fort Howard, Maryland, and the 3rd Cavalry Regiment, supported by six battle tanks commanded by Maj. George S. Patton, formed in Pennsylvania Avenue while thousands of civil service employees left work to line the street and watch. The Bonus Marchers, believing the troops were marching in their honor, cheered the troops until Patton ordered[citation needed] the cavalry to charge them—an action which prompted the spectators to yell, "Shame! Shame!"
After the cavalry charged, the infantry, with fixed bayonets and tear gas (adamsite, an arsenical vomiting agent) entered the camps, evicting veterans, families, and camp followers. The veterans fled across the Anacostia River to their largest camp and President Hoover ordered the assault stopped. However Gen. MacArthur, feeling the Bonus March was an attempt to overthrow the U.S. government, ignored the President and ordered a new attack. Fifty-five veterans were injured and 135 arrested.[12] A veteran's wife miscarried. When 12-week-old Bernard Myers died in the hospital after being caught in the tear gas attack, a government investigation reported he died of enteritis, while a hospital spokesman said the tear gas "didn't do it any good."[16]
During the military operation, Major Dwight D. Eisenhower, later the 34th President of the United States, served as one of MacArthur's junior aides.[17] Believing it wrong for the Army's highest-ranking officer to lead an action against fellow American war veterans, he strongly advised MacArthur against taking any public role: "I told that dumb son-of-a-bitch not to go down there," he said later. "I told him it was no place for the Chief of Staff."
