Monica, the convent situated in a line with Las Tenerias, a little to the north of the Calle de Pabostre; but its walls offered a strong resistance, and it was not as easy to take as the fragile houses which the booming of the cannon caused to tremble. The volunteers of Huesca defended it vigorously; and, after repeated attacks, the besiegers left the assault for another day. Having gained possession only of a few houses, they remained in them when night came, like rabbits in a warren. Woe to the head that appeared at a window! The neighboring walls, the roofs, the skylights were filled with attentive eyes that saw the least carelessness of a French soldier, and guns were ready for him. When night came, we began to make holes in the partition walls in order to open communication between all the houses in the same block. In spite of the incessant noise of the cannon, we could hear within the buildings the picks of the enemy occupied in the same sort of work as ourselves. As the architecture was fragile, and almost all the partition walls were of earth, we had in a short time opened passages between many houses. About ten o'clock at night, we found ourselves in one which we knew must be very near that of Manuela Sancho, when we heard, through unknown conduits, through cellars and subterranean passages, a sound which we realized must be the voices of the enemy. A terrified woman came up a ladder and told us that the French were opening a gap in the wall of the room below. We descended instantly. We were not yet all in the cold, narrow, dark place, when at its mouth a gun was fired at us, and one of our companions was slightly wounded in the shoulder. By the dim light we perceived several figures that forced their way into the room, and, advancing, fired, while others came behind. At the noise of gunshots, our friends hurried down to us, and we penetrated boldly into the dark place. The enemy did not remain in it, and as swiftly as possible hurried back through the hole they had opened in the wall, seeking refuge in the place whence they had come. We sent some balls after them. We were not completely in darkness, as they had a lantern some of whose feeble rays came through the aperture diffusing a reddish light over the theatre of the struggle.
