Before The Peace Establishment Act of 1802, the U.S. Military Academy at West Point was ran a little differently. When the West Point location was first founded in the 1790s it was the headquarters for the Corps of Artillerists and Engineers. It was still a site of an attempt to formalize officer training, but the training was being conduct by foreign officers. There seemed to be a problem with American men being trained by foreign nations. Young Lieutenants and captains deeply resented being taught by foreigners, and the foreign officers themselves soon got cross ways with fellow American officers-so much so that in one case an argument led to a duel(American Military History, pg. 73). Thomas Jefferson knew this could no longer continue. So, on March 16th, 1802, President Jefferson signed The Peace Establishment Act of 1802.
This Act authorized Jefferson to discharge the Federalist officers and replace them with their very own Republicans. That dramatically reshaped the Army and in essence made the West Point Academy what it is today.
