Despite calls to replace the monarchy with a republic, Louis retained his position but was generally regarded with acute suspicion and forced to swear allegiance to the constitution. A new decree stated retracting this oath, making war upon the nation, or permitting anyone to do so in his name would be considered abdication. However, radicals led by Jacques Pierre Brissot prepared a petition demanding his deposition, and on 17 July, an immense crowd gathered in the Champ de Mars to sign. Led by Lafayette, the National Guard was ordered to "preserve public order" and responded to a barrage of stones by firing into the crowd, killing between 13 and 50 people.
