Now it is an accusation totally devoid of foundation, as I shall presently show; and I took this opportunity of vindicating the reputation of De Boigne, by simply stating that De Boigne could never have betrayd Tippoo, since he was never in his service; 2dly, that he had, when in the service of Scindiah, fought against Tippoo, when the Mahrattas coalesced with the English against that Prince in 1792; and that had it not been for the assistance given by the Mahrattas to the English (a most impolitic coalition on the part of the Mahrattas, as it turned out afterwards), Tippoo would not have been compelled to conclude so humiliating a treaty of peace; 3dly, that De Boigne had quitted India in 1796, three years before the second war and death of Tippoo in 1799. I stated, too, that I was perfectly well acquainted with these particulars of De Boigne's career, from having served six years in India, and from having been personally acquainted with a gentleman of the name of Lucius Ferdinand Smith, who was the ultimate friend of De Boigne and his lieutenant general in the service of Scindiah; I added that I could not conceive how so unjust and unfounded an aspersion on De Boigne's character could find currency. I hope that what I said will be effectual towards doing away this injurious report; but very probably it will not, for when the vulgar once imbibe an opinion, it is difficult to eradicate it from their minds, and they are not at all obliged to the person who endeavors to undeceive them, so that General De Boigne's treachery and sale of Tippoo to the English will be handed down to posterity among the Savoyards, as a fact of which it will be as little permitted to doubt as of the treachery of Judas.
