The Emperor Francis determined to remain at Aube, with the division under General Ducca, not thinking it becoming him to join in the attack on the French capital where his daughter ruled as empress-regent; and a body of ten thousand cavalry, under command of Winzengerode and Czernicheff, was ordered to watch the motions of Napoleon and intercept his communications with Paris, whilst the Russian and Prussian light troops scoured the roads in advance, stopping all couriers. Blucher, at the same time, having thrown open the gates of Rheims, was moving on Châlons and Vitry, to form a junction with the army of Schwarzenberg. The flying parties captured, near Sommepuix, a convoy of artillery and ammunition; and, on another occasion, they fell in with a courier bearing a budget of the most melancholy intelligence to the Emperor--that the British had made a descent on Italy; that the Austrians had defeated Augereau, and were in possession of Lyons; that Bordeaux had declared for Louis XVIII.; and that Wellington was at Toulouse. These tidings gave immense confidence to the Allies. Near Fère-Champenoise the Allies met, finding Blucher in the act of stopping a body of infantry, five thousand in number, which was bearing provisions and ammunition to the army of Napoleon. The column consisted of young conscripts and National Guards, who had never been in action, but they bravely defended their charge till they were surrounded by the mingling forces of the two armies, and compelled to surrender. [Illustration: ALEXANDER I.] The Allies now advanced in rapid march. They put to flight the divisions of Mortier and Marmont, whom Buonaparte had posted to give them a check. These divisions lost eight thousand men, besides a vast quantity of guns, baggage, and ammunition. A similar fate awaited a body of ten thousand National Guards. At Meaux Mortier and Marmont blew up a great powder-magazine as Blucher approached, and then retired beneath the walls of Paris. The Allies, in three days, had marched seventy miles. On the 28th of March they were in full view of Paris, and had driven Marmont and Mortier close under its walls. The north-east side of Paris, on which they were approaching, was the only one then fortified. A ridge of hills along that side, including the heights of Belleville, Romainville, and Montmartre, was defended by an old wall, and there the French authorities had placed the defenders of the city--the shattered forces of the two retreating marshals, bodies of the National Guard, and youths from the Polytechnic schools, many of them mere boys of from twelve to sixteen years old, some of whom served the guns on the batteries. The whole of the forces left to defend the great and wealthy city of Paris amounted to between thirty and forty thousand men. [Illustration: NAPOLEON SIGNING HIS ABDICATION. (_See p._ 83.)]
