Dr. Wittman assures his readers that whilst he was in Egypt with the army, a man was pointed out to them as having been the executioner of Napoleon’s commands to poison the sick and wounded French soldiers in the hospitals of Jaffa. Barre says: ‘Although neither Sir Robert Wilson nor Dr. Wittman mention the name of the worthy physician who refused with horror, and of the infamous wretch, who basely consented to become the executioner of the sick soldiers, it is now well known that the former was the worthy physician Dr. Desgenettes, and the latter, one Rouyer, an infamous apothecary, who thus became the murderer of his own countrymen, in compliance with the wishes of a Corsican assassin.’ In a little periodical, called ‘Ring the Alarum Bell!’ (which only ran four numbers), published in 1803, is the following, written by a General Danican: ‘In 1801, I met at a lazaretto in Sicily, with a number of French Soldiers just come from Alexandria. With one of them I contracted habits of intimacy during my stay, and who frequently related to me some curious particulars of the conduct of Buonaparté in Egypt.... Having been witness to the poisoning scene at Caiffa he related to me the following anecdote. A grenadier, who had lost two brothers, was amongst the unfortunate wretches slightly affected with the pestilential disease. From what he had previously observed in the hospital, he had become more suspicious than his companions in distress, and he had scarcely taken the _Corsican physic_, than he immediately discharged it, made his way out of the hospital, and escaping the guard, whom he contrived to knock down, he gained the column under the command of Kleber, at whose feet he threw himself, and, in the intercession, almost of despair, conjured him to let him mount one of the camels, describing what he had escaped from, and venting the most energetic maledictions on the _Poisoner in Chief_. The poor wretch, in the most piteous manner, assured General Kleber that he would keep at a distance from the army, so that no one should be in any danger of catching his disorder, except the camel. Kleber granted his request; the grenadier was saved and recovered, and was alive when the English landed under the brave Abercrombie.’
