He is one of 19 people to twice receive the Medal of Honor, one of three to be awarded both the Marine Corps Brevet Medal and the Medal of Honor, and the only person to be awarded the Brevet Medal and two Medals of Honor, all for separate actions.
In addition to his military achievements, he served as the Director of Public Safety in Philadelphia for two years and was an outspoken critic of U.S. military adventurism. In his 1935 book War is a Racket, he described the workings of the military-industrial complex and, after retiring from service, became a popular speaker at meetings organized by veterans, pacifists and church groups in the 1930s.
In 1934 he was involved in a controversy known as the Business Plot when he told a congressional committee that a group of wealthy industrialists had approached him to lead a military coup to overthrow Franklin D. Roosevelt. The individuals that were involved denied the existence of a plot, and the media ridiculed the allegations. The final report of the committee stated that there was evidence that such a plot existed, but no charges were ever filed. The opinion of most historians is that while planning for a coup was not very advanced, wild schemes were discussed. (Courtesy, WikiPedia)
