Which is not a last name, MacArthur or Bonus?, Context: His primary duty was planning for the next war, which proved most difficult in the midst of the Great Depression. He then was posted as chief military aide to General MacArthur, Army Chief of Staff. In 1932, he participated in the clearing of the Bonus March encampment in Washington, D.C. Although he was against the actions taken against the veterans and strongly advised MacArthur against taking a public role in it, he later wrote the Army's official incident report, endorsing MacArthur's conduct.
