The reign of terror began on the night of the 10th of March!793, when the greatest number and the best part of the real friends to freedom had retired [from the Convention]. But, as the intention of the conspiracy against the Assembly had been suspected, as the greatest part of the Deputies they wished to sacrifice had been informed of the threatening danger, as, moreover, a mutual fear [existed] of the cunning tyranny of some usurper, the conspirators, alarmed, could not this night consummate their horrible machinations. They therefore, for this time, confined themselves to single degrees of accusation and arrestation against the most valuable part of the National Convention. Robespiere had placed himself at the head of a conspiring Common-Hall, which dared to dictate _laws of blood_ and proscription to the Convention. All those whom he could not make bend under a Dictatorship, which a certain number of anti-revolutionists feigned to grant him, as a tool which they could destroy at pleasure, were guilty of being suspected, and secretly destined to disappear from among the living. Thomas Paine, as his marked enemy and rival, by favour of the decree on the suspected was classed among the suspected, and, as a foreigner, was imprisoned in the Luxembourg in December 1793. (See Letter to Washington.) ¦ From this document it will be seen, that, while in the prison, he was, for a month, afflicted with an illness that deprived him of his memory. It was during this illness of Thomas Paine that the fall of Robespierre took place. Mr. Monroe, who arrived at Paris some days afterwards, wrote to Mr. Paine, assuring him of his friendship, as appears from the letter to Washington. Fifteen days afterwards Thomas Paine received a letter from Peter Whiteside.** In consequence of this letter Thomas Paine wrote a memorial to Mr. Monroe. Mr. Monroe now claimed Thomas Paine, and he _came out of the prison on the 6th of November, 1794, after ten months of imprisonment_. He went to live with Mr. Monroe, who had cordially offered him his house. In a short time after, the Convention called him to take his seat in that Assembly; which he did, for the reasons he alleges in his letter to Washington. The following two pieces Thomas Paine wrote while in Prison: "Essay on Aristocracy." "Essay on the character of Robespierre." [Both missing.] * This is the bitter letter of which when it appeared Cobbett had written such a scathing review. ** The letter telling him of the allegations made by some against his American citizenship. Thomas Paine received the following letter from Madame Lafayette, whose husband was then a prisoner of war in Austria:
