During the night of the 11th of November, Forcia had a second breach opened, and marked out the approach-works, as shown in Fig. 64. Besides the two _places d'armes_ A and B, already marked out, he planned a third, C, to be reached by a new trench D, next two batteries at G and F, for two pieces each, and a battery for two mortars H. He had the first trench lengthened at I, with a piece at its extremity sweeping the curtain K. Two pieces mounted in the _place d'armes_ B commanded the battery F, and the surroundings; a piece mounted at E commanded the battery G; and a piece mounted in the _place d`armes_ C swept the outside of the western battery. He thought he should thus provide for every contingency. If the besieged determined to attempt some bold stroke, they could not advance far, and if they succeeded in taking either of the batteries G, F, he could crush them. The two batteries G, F were intended to silence the fire of the north-west salient and of the left half of the tenaille. That done, he could--secure against the right-hand fire--advance as far as the counterscarp, set up a breach battery, and take the place by the north-west salient. Meanwhile, the mortar battery would render the right of the work untenable, crush the defenders of the ancient terraced walls, damage the gates, and prevent the besieged from attempting anything at this point. The plan was not badly conceived; nothing remained but to execute it. The phlegmatic governor had the gabionades of the work strengthened, and traverses and _paréclats_ raised, especially on the platforms of the two great towers. He had shelter places arranged on the platforms of the earthworks. Moreover he kept up a continual fire on the workmen, so that they could scarcely make any advance except during the night. Sometimes at ten o'clock at night, sometimes at midnight, at two o'clock in the morning, or shortly before daybreak, Rincourt would alarm the enemy's camp by sorties of no importance considered with reference to the final result, but which greatly exhausted the besiegers. These sorties were effected by one or two companies while the others rested. In this way he exercised the militia, and accustomed them to fighting. By the 15th of November the besieger's works had scarcely made any progress. However the _place d'armes_ C was made, as also the parallel which connected it with the _place d'armes_ B; and the trenches were commenced which were to lead to the two batteries. The bomb-mortars were mounted, and began to fire towards evening. But they produced more noise than damage to the besieged. Their fire was badly directed, and most of the bombs burst too soon or too late. The besieged became accustomed to them, and kept out of their way when they saw them coming. For a dozen bombs fired the first evening, two men were wounded, and one gun-carriage damaged.
