On February 8th, at one in the afternoon, Captain Roese had gabions flung into the ditch of Hautes Perches, sprang into it with five sappers, and rapidly scaled the parapet by the steps hewn in the scarp. He was immediately followed by the trench guard, but only a few of the French were surprised in the casemated traverses. The situation of the garrison of the forts had in fact become extremely difficult. Ammunition had to be brought up under the enemy's fire, water could only be had from the pond at Vernier, and cooking could only be done inside the works. Colonel Denfert had already given orders to bury the material. Unseen by the besiegers the guns of which the carriages could still be moved had been withdrawn, and only one company left in each fort, which in case of a surprise was to fire and fly. Nothing was to be found in the abandoned work but wrecked gun-carriages and four damaged guns. This fort was at once reversed so that its front faced the fortress, but at three o'clock the latter opened so heavy a fire on the lost positions that the working parties had to take shelter in the ditches. The garrison in Basses Perches attempted some resistance, but under cover of a reserve it soon retired to Le Fourneau, leaving five guns and much shattered material. Here also the fire of the place at first compelled the working parties to break off, but four 15-cm. mortars were at length brought into the fort, and two 9-cm. guns were placed on the spur of the hill to the westward, which directed their fire on Le Fourneau and Bellevue. During the night of the 9th the two works were connected by a shelter-trench 680 yards long, and thus the third parallel was established. The position was now such that the attack could immediately be directed on the citadel, and on it the batteries in the Bois des Perches and presently those in the second parallel opened fire. Moitte, Justice, and Bellevue were shelled simultaneously. General von Debschitz had returned, so that the investing corps was thus again brought up to its full strength, and all the conditions were improved by the return of the frost. By the 13th ninety-seven guns were ready in the third parallel.
