He had to arrange the disbanding of the Imperial and the re-organization of a Royal army; he had to examine and decide upon the various claims presented by hundreds of soldiers; he had to satisfy the demands of two thousand officers who adhered to the king, and to send them into the interior; he had to classify nine thousand officers of the disbanded army; to arrange for the pay of six thousand others who were _re-formed_--that is, continued on pay, but without being regimented; he had to examine six thousand claims for arrears of pay and pensions, claims that could admit of no delay, and which amounted to forty-six millions of francs; he had to organize the Royal Garde du Corp; to reconstitute the gendarmerie; to provide for the maintenance of the allied armies of occupation; and all this he had to do, amid obstacles, disorders, and complexities without example. Such was the mighty mass of labour submitted to the care of Clarke; and of this herculean task he nobly and ably acquitted himself in less than two years. All impartial writers unite in exculpating him from the angry and unjust accusation of peculating with the enormous sums which were required and absorbed by the re-organization of the French army. But he was severely handled by military men for instituting those tribunals styled _Les Cours Prevotales_. In June, 1815, Clarke was with Louis XVIII. at Arnouville, and while there saved his friend, Francois Marquis de Lagrange, a lieutenant-general who in 1813 commanded the 3rd Regiment of Gardes d'Honneur, from great danger, if not from death. The marquis had been accused of offering his services to Napoleon, and hastily arrived at Arnouville with his son, on the 30th June. As he was about to wait upon Louis he was assailed by several soldiers, in whose hearts the love of Napoleon was strong. They called him a _traitor_, and tore away his sword, cross, and epaulettes. On becoming aware of these outrages, Clarke sent two influential officers to repress the tumult, and himself led the marquis to Louis XVIII., who appointed him captain of the Black Musketeers. The zeal which Clarke now employed in the cause of the house of Bourbon was ultimately the means of his downfall. Louis XVIII., who each day conceded more and more to the enemies of his dynasty, after bestowing upon Clarke the baton of a Marshal of France, displaced him from office, and appointed Gouvin St. Cyr in his room. We know that after his dismissal all was changed in the department of the Minister of War.
