As we had several of Napoleon's soldiers at dinner yesterday, and they had united to praise the military character of the position taken by the revellers, I was curious to examine it. The Rue St. Méry is narrow, and the houses are high. The tower of the church is a little advanced, so as to enfilade it, in a manner, and the paving-stones had been used to make barricades, as in 1830. These stones are much larger than our own, are angular, and of a size that works very well into a wall; and the materials being plenty, a breastwork, that is proof against everything but artillery, is soon formed by a crowd. Two streets entered the Rue St. Méry near each other, but not in a right line, so that the approach along each is commanded by the house that stands across its end. One of these houses appears to have been a citadel of the disaffected, and most of the fighting was at and near this spot. Artillery had been brought up against the house in question, which was completely riddled, though less injured by round-shot than one could have thought possible. The windows were broken, and the ceilings of the upper rooms were absolutely torn to pieces by musket-balls, that had entered on the rise. Some twenty or thirty dead were found in this dwelling. I had met Col.--, in the course of the morning, and we visited this spot together. He told me that curiosity had led him to penetrate as far as this street, which faces the citadel of the revolters, the previous day, and he showed me a _porte-cochère_, under which he had taken shelter, during a part of the attack. The troops engaged were a little in advance of him, and he described them as repeatedly recoiling from the fire of the house, which, at times, was rather sharp. The troops, however, were completely exposed, and fought to great disadvantage. Several hundreds must have been killed and wounded at and near this spot.
