Pitt was now seriously occupied with the state of Europe. The King of Sweden, Gustavus III., had been assassinated at a masked ball; the Emperor Leopold was dead; his son, the Emperor Francis, in concert with the King of Prussia, declared war against France. The position of Louis XVI. became each day more precarious. {363} Tossed about without hope, at one time contemplating impossible resistance, at another, useless concessions, he had, on the 20th of June, 1792, endured the insults and outrages of the Parisian populace. The allied troops, under the Duke of Brunswick, had already entered French territory. The princes of the House of Bourbon, at the head of the emigré's, prepared themselves to sustain the operations of the foreigners; an ill-timed manifesto excited still further the passions of the French. On the 10th of August, 1792, the palace of the Tuilleries was attacked, and the Swiss guards massacred. The king, suspended from his royal functions, was confined in the Temple, with his family; the convention was convoked, and the prisoners in the dungeons of Paris were murdered. Amidst the chaos which reigned in Paris, La Fayette, who commanded a French army upon the frontier, could not resolve to defend a state of things each day more contrary to his presumptuous expectations; he secretly quitted his command, intending to fly to America. He was arrested by the allies and put in prison at Olmutz. General Dumouriez fought the allied army at Jemappes, on the 6th of November, 1792. Kellerman had defeated them at Valmy on the 20th of September; the allied troops evacuated French territory, and the French army entered Belgium. Savoy was already in the hands of the French troops, and General Custine advanced into Germany. By its decree of the 19th of November, the Convention declared, in the name of the French nation, that they would grant succor and fraternity to every people who desire to obtain liberty. {364} Before this supreme disregard of ancient rights and international conventions, Mr. Pitt, still favorable to preserving neutrality, was nevertheless alarmed at the threatened fate of Holland. He wrote to his colleague, the Marquis of Stafford, that the strange and unfortunate events which have succeeded each other so rapidly upon the continent, give us ample material for serious reflection. That which is most urgent is the situation of Holland. However painful it may be to see this country engaged, it seemed impossible to him, to hesitate upon the question of sustaining our ally in case of necessity; and the explicit declaration of our sentiments is the best way to avoid this situation at present. Perhaps some opening would present itself which would allow us to contribute to the termination of the war between the different powers of Europe, by leaving France to arrange her internal affairs as well as she could; which was, he thought, the best plan. The trial of Louis XVI. had already commenced.
