When the King (Louis XVIII.) was preparing for his journey from Warsaw to Grodno an atrocious attempt to assassinate him was brought to light, which leaves no manner of doubt that it was the purpose of those who were the secret movers in the plot to remove by poison both the King and Queen and also the Duke of Angoulême and his wife. Two delegates of Napoleon had been in Warsaw seeking for a man who could execute the plan. A certain Coulon appeared most adapted to their purpose, a man indigent and eager for money. He had previously been in the service of one of the emigré nobles, and had access to the kitchen of the Royal Family. [3] A. de Beauchamp, Vie de Louis XVIII. Paris, 1824. The agents of Napoleon gave Coulon drink, and as he became friendly and lively under the influence of punch, they communicated to him their scheme, and promised him money, the payment of his debts, and to effect his escape if he would be their faithful servant in the intrigue. Coulon pretended to yield to their solicitations, and a rendezvous was appointed where the plans were to be matured. But no sooner was Coulon at liberty than he went to his former master, the Baron de Milleville, master of horse to the Queen, and told him all. The Baron sought the Duc de Pienne, first gentleman of the Royal household, and he on receiving the information communicated it to the Count d'Avaray, Minister of Louis XVIII. Coulon received orders to pretend to be ready to carry on the plot. He did this with reluctance, but he did it. He told the agents of Napoleon that he was in their hands and would blindly execute their orders. They treated him now to champagne, and revealed to him the details of the attempt. He was to get into the kitchen of the Royal household, and was to pour the contents of a packet they gave him into one of the pots in which the dinner for the Royal table was being cooked. Coulon then demanded an instalment of his pay, and asked to be given 400 louis d'or. One of the agents then turned to the other and asked if he thought Boyer would be disposed to advance so much--this was Galon Boyer, the head agent sent purposely to Warsaw as spy on the Royal Family, and the principal mover in the attempt. The other agent replied that Boyer was not at the moment in Warsaw, but he would be back in a couple of days. Coulon stuck to his point, like a clever rascal, and refused to do anything till he felt gold in his palm, and he was bidden wait till Boyer had been communicated with. He was appointed another meeting on the moors at Novawies outside the city.
