We visited with deep interest the projecting part of the heights of Belleville, immediately overlooking the Fauxbourg St Martin, which the Emperor Alexander reached, with the king of Prussia, the Prince Schwartzenburg, and the whole general staff, on the evening of the 30th of March. It was here that he received the deputation from Marshals Marmont and Mortier, who had fought all day against a vast superiority of force, and been fairly overpowered, recommending Paris to the generosity of the allies. Thirty howitzers were placed on this height, and a few shells were thrown into the town, one or two of which, we were assured, reached as far as the Eglise de St Eustace; it is allowed on all hands that they fell within the Boulevards. The heights of Montmartre were at the same time stormed by the Silesian army, and cannon were placed on it likewise,--Paris was then at his mercy. After a year and a half of arduous contest, it was at length in his power to take a bloody revenge for the miseries which his subjects had suffered during the unprovoked invasion of Russia.--He ordered the firing to cease; assured the French deputation of his intention to protect the city; and issued orders to his army to prepare to march in, the next morning, in parade order. He put himself at their head, in company with the King of Prussia, and all the generals of high rank. After passing along the Boulevards to the Champs Elysees, the sovereigns placed themselves under a tree, in front of the palace of the Thuilleries, within a few yards of the spot where Louis XVI. and many other victims of the revolution had perished; and they saw the last man of their armies defile past the town, and proceed to take a position beyond it, before they entered it themselves. At this time, the recollection of the fate of Moscow was so strong in the Russian army, and the desire of revenge was so generally diffused, not merely among the soldiers, but even among the superior, officers, that they themselves said, nothing could have restrained them but the presence and positive commands of their Czar; nor could any other influence have maintained that admirable discipline in the Russian army, during its stay in France, which we have so often heard the theme of panegyric even among their most inveterate enemies. It is not in the columns of newspapers, nor in the perishable pages of such a Journal as this, that the invincible determination, the splendid achievements, and the generous forbearance of the Emperor of Russia and his brave army, during the last war, can be duly recorded; but when they shall have passed into history, we think we shall but anticipate the sober judgment of posterity by saying, that the foreign annals of no other nation, ancient or modern, will present, in an equal period of time, a spectacle of equal moral grandeur. * * *
