“Lincoln was the last President to use the military against US citizens.”
Sorry but this is an incorrect statement of history. President Hoover ordered the last military against US Citizens:
The Bonus Army
Six years after the end of World War I Congress enacted a bill that would reward veterans of the conflict a cash bonus for their service. However, the legislation stipulated that the veterans would not collect their bonus until 1945.
Tanks and cavalry prepare to
evacuate the Bonus Army
July 28, 1932This delayed gratification was acceptable to the World War I veterans during the prosperous ‘20s but the onslaught of the Great Depression changed their attitude. Out of work, destitute, and with families to feed, the veterans organized a march on Washington in May of 1932 to force Congress to immediately pay their bonus. An estimated 15,000 made their way to the nation’s capital and dubbed themselves the “Bonus Expeditionary Force.”
Using scrap wood, iron and any other loose materials they could find, the veterans set up ramshackle camps throughout the city. The largest housed an estimated 10,000 people. They waited in vain for Congress to act. On June 17 the Senate voted against the House-passed bill that would have given the Bonus Marchers immediate payment of their benefit.
Having no other place to go, the majority of the Bonus Army remained encamped in the city, despite the fact that Congress had adjourned for the summer. Finally, President Hoover ordered the Army to forcibly remove the veterans. On July 28 a force of tanks and cavalry under the command of General Douglas MacArthur stormed the camps and drove the veterans out. Their makeshift houses were then set ablaze.
Some of our most revered military personnel of WWII were part of it: MacArthur in the lead while Eisenhower, was MacArthur’s aide at the time, and even Patton were participants.
