Such is the legend as formulated by M. de Beauchamp. Fortunately there exists documentary evidence in the archives of the courts at Berlin that gives an altogether different complexion to the story, and entirely clears the name of Napoleon from stain of complicity in this matter. It throws, moreover, a light, by no means favourable, on those of the Legitimist party clustered about the fallen monarch.
Louis XVIII., obliged to fly from one land to another before the forces of Napoleon, was staying for a while at Warsaw, in the year 1804, under the incognito of the Count de l'Isle. His misfortunes had not broken his spirit or diminished his pretensions. He was surrounded by a little court in spite of his incognito; and as this little court had no affairs of State to transact, it played a niggling game at petty intrigue. This court consisted of the Count d'Avaray, the Archbishop of Rheims, the Duke de Pienne, the Marquis de Bonney, the Duke d'Avré de Croy, the Count de la Chapelle, the Counts Damas Crux and Stephen de Damas, and the Abbés Edgeworth and Frimont. Louis had assured Napoleon he would rather eat black bread than resign his pretensions. At Warsaw he maintained his pretensions to the full, but did not eat black bread; he kept a very respectable kitchen. The close alliance between Prussia and France forced him to leave Warsaw and migrate into Russia.
At this time there lived in Warsaw a certain Jean Coulon, son of a small shopkeeper at Lyons, who had led an adventurous life. At the age of nine he had run away from home and attached himself to a wandering dramatic company; then had gone into service to a wigmaker, and had lived for three years at Barcelona at his handicraft. But wigs were going out of fashion, and he threw up an unprofitable trade, and enlisted in a legion of emigrés, but in consequence of some quarrel with a Spaniard was handed over to the Spanish authorities. He purchased his pardon by enlisting in the Spanish army, but deserted and joined the French Republican troops, was in the battle of Novi, ran away, and joined the corps raised at Naples by Cardinal Ruffo. When this corps was dispersed, he went back to Spain, again enlisted, and was shipped for St. Lucia. The vessel in which he was, was captured by an English cruiser, and he was taken into Plymouth and sent up to Dartmoor as prisoner of war. After two years he was exchanged and was shipped to Cuxhaven. Thence he went to Altona, where he asked the intervention of the Duke d'Avré in his favour. The Duke recommended him to the Countess de l'Isle, and he was taken into the service of her master of horse, the Baron de Milleville, and came to Warsaw in September, 1803. There he married, left his service and set up a café and billiard room that was frequented by the retainers and servants of the emigré nobility that hovered about the King and Queen. He was then aged 32, could speak Italian and Spanish as well as French, and was a thorough soldier of fortune, impecunious, loving pleasure, and wholly without principles, political or religious.
The French Chargé d'Affaires at Warsaw was Galon Boyer; he does not appear in the documents relative to the Affaire Coulon, not because the Prussian Government shirked its duty, but because he was in no way mixed up with the matter of the parsnips. It is quite true that, as M. de Beauchamp asserts, the Court of Louis XVIII. did endeavour to involve the Prussian authorities in the investigation, but it was in such a manner that it was not possible for them to act. On July 23rd, when the Count de l'Isle was determined to leave Warsaw, Count d'Avaray called on the President von Hoym, and told him in mysterious language that he was aware of a conspiracy in which were involved several Frenchmen and as many as a dozen Poles that sought the life of his august master. Herr von Hoym doubted. He asked for the grounds of this assertion, and was promised full particulars that same evening at eight o'clock. At the hour appointed, the Count appeared breathless before him, and declared that now he was prepared with a complete disclosure. However, he told nothing, and postponed the revelation to 10 o'clock. Then Avaray informed him that the keeper of the Café Coulon had been hired by some strangers to meet him that same night on the road to Novawies, to plan with him the murder, by poison, of the Count de l'Isle. The whole story seemed suspicious to von Hoym. It was now too late for him to send police to watch the spot where the meeting was to take place, which he might have done had d'Avaray condescended to tell him in time, two hours earlier. He asked d'Avaray where Coulon lived that he might send for him, and the Count professed he did not know the address.
Next day Count d'Avaray read to the President von Hoym a document, which he said had been drawn up by members of the court of the Count de l'Isle, showed him a paper that contained twelve small parsnips, and requested him to subscribe the document and seal the parcel of parsnips. Naturally, the President declined to do this. He had not seen Coulon, he did not know from whom Coulon had received the parcel, and he mistrusted the whole story. However, he requested that he might be furnished with an exact description of the two mysterious strangers, and when he had received it, communicated with the police, and had inquiry made for them in and about Warsaw. No one had seen or heard of any persons answering to the description.
Presently the Marquis de Bonney arrived to request the President, in the name of the Count de l'Isle, to have the parsnips examined by specialists. He declined to do so.
On July 26th, the Count d'Avaray appeared before the head of the Police, the President von Tilly, and showed him an attestation made by several doctors that they had examined three parsnips that had been shown them, and they had found in them a paste composed of arsenic and orpiment. Von Tilly thought the whole story so questionable that he refused to meddle with it. Moreover, a notary of Warsaw, who had been requested to take down Coulon's statement, had declined to testify to the genuineness of the confession, probably because, as Coulon afterwards insinuated, he had been helped to make it consistent by those who questioned him.
Louis XVIII. left Warsaw on July 30, and as the rumour spread that Coulon's wife had bought some arsenic a week before at an apothecary's shop in the place, the police inspector ordered her arrest. She was questioned and declared that she had, indeed, bought some rat poison, without the knowledge of her husband. Coulon was now taken up and questioned, and he pretended that he had given his wife orders to buy the rat poison, because he was plagued with vermin in the house.
Then the authorities in Warsaw sent all the documents relating to this matter, including the procès verbal drawn up by the courtiers of Louis XVIII., to Berlin, and asked for further instructions.
According to this procès verbal Coulon had confessed as follows: On the 20th July two strangers had entered his billiard room, and had assured him that, if he were disposed to make his fortune, they could help him to it. They made him promise silence, and threatened him with death if he disclosed what they said. After he had sworn fidelity and secrecy, they told him that he was required to throw something into the pot in which the soup was being prepared for the King's table. For so doing they would pay him 400 louis d'or. Coulon considered a moment; then the strangers promised they would provide a situation for his wife in France. After that one of them said to his fellow in Italian, "We must be off. We have no time to lose." Next day, in the evening, a third stranger appeared at his door, called him forth into the street, walked about with him through the streets of old and new Warsaw, till he was thoroughly bewildered, and did not know where he was, and, finally, entered with him a house, where he saw the two strangers who had been with him previously. Champagne was brought on the table, and they all drank, and one of the strangers became tipsy. When Coulon promised to do what was required of him, he was told to secure some of the mutton-chops that were being prepared for the Royal table, and to manipulate them with the powder that was to be given him. That the cook might not notice what he was about, he was to treat him to large draughts of brandy. Coulon agreed, but asked first to touch the 400 louis d'or. Then the tipsy man shouted out,
