General Blaise has been killed at Villa Evrard. The buildings, which go by this name, were occupied on Wednesday by General Vinoy's troops. In the night a number of Prussians, who had concealed themselves in the cellars, emerged, and a hand-to-hand fight took place. Some of the Prussians in the confusion got away, and some were killed. Several French officers who ran away and rushed in a panic into the presence of General Vinoy, who was at Fort Rosney, announcing that all was lost, are to be tried by Court Martial. The troops when they heard this were very indignant; but old Vinoy rode along the line, and told them that they might think what they pleased, but that he would have no cowards serving under him. Pity that he is not General-in-Chief. A curious new industry has sprung up in Paris. Letters supposed to be found in the pockets of dead Germans are in great request. There are letters from mothers, from sisters, and from the Gretchens who are, in the popular mind, supposed to adore warriors. Unless every corpse has half a dozen mothers, and was loved when in the flesh by a dozen sweethearts, many of these letters must be fabricated. They vary in their style very little. The German mothers give little domestic details about the life at home, and express the greatest dread lest their sons should fall victims to the valour of the Parisians, which is filling the Fatherland with terror and admiration. The Gretchens are all sentimental; they talk of their inner feelings like the heroines of third-rate novels, send the object of their affections cigars and stockings knitted by their own fair hands, and implore him to be faithful, and not forget, in the toils of some French syren, poor Gretchen. But what is more strange is that in the pocket of each corpse a reply is found which he has forgotten to post. In this reply the warrior tells a fearful tale of his own sufferings, and says that victory is impossible, because the National Guards are such an invincible band.
