When the regiment to which Trevanion belonged became part of the army of occupation in Paris, he was left at Versailles seriously ill from the effects of a sabre-wound he received at Waterloo, and from which his recovery at first was exceedingly doubtful. At the end of several weeks, however, he became out of danger, and was able to receive the visits of his brother officers, whenever they were fortunate enough to obtain a day's leave of absence, to run down and see him. From them he learned that one of his oldest friends in the regiment had fallen in a duel, during the time of his illness, and that two other officers were dangerously wounded--one of whom was not expected to survive. When he inquired as to the reasons of these many disasters, he was informed that since the entrance of the allies into Paris, the French officers, boiling with rage and indignation at their recent defeat, and smarting under the hourly disgrace which the presence of their conquerors suggested, sought out, by every means in their power, opportunities of insult; but always so artfully contrived as to render the opposite party the challenger, thus reserving to themselves the choice of weapons. When therefore it is borne in mind that the French are the most expert swordsmen in Europe, little doubt can exist as to the issue of these combats; and, in fact, scarcely a morning passed without three or four English or Prussian officers being carried through the Barriere de l'Etoile, if not dead, at least seriously wounded, and condemned to carry with them through life the inflictions of a sanguinary and savage spirit of revenge. While Trevanion listened to this sad recital, and scarcely did a day come without adding to the long catalogue of disasters, he at once perceived that the quiet deportment and unassuming demeanour which so strongly characterise the English officer, were construed by their French opponents into evidences of want of courage, and saw that to so systematic a plan for slaughter no common remedy could be applied, and that some "coup d'etat" was absolutely necessary, to put it down once and for ever. In the history of these sanguinary rencontres, one name was continually recurring, generally as the principal, sometimes the instigator of the quarrel. This was an officer of a chasseur regiment, who had the reputation of being the best swordsman in the whole French army, and was no less distinguished for his "skill at fence," than his uncompromising hatred of the British, with whom alone, of all the allied forces, he was ever known to come in contact. So celebrated was the "Capitaine Augustin Gendemar" for his pursuits, that it was well known at that time in Paris that he was the president of a duelling club, associated for the express and avowed object of provoking to insult, and as certainly dooming to death every English officer upon whom they could fasten a quarrel.
