The haste with which, while an enemy was at hand, the walls had been constructed, had not allowed of giving to them that height and solidity which were requisite for effectually resisting an attack. In 1369, Charles the Fifth resolved to remedy this defect. The task of making the necessary improvements was committed to Hugh Aubriot, the provost of Paris. Among the changes which Aubriot made, was the adding of two towers to those which already existed at St. Anthony’s gate. They were erected parallel with those built by Marcel; so that the whole formed a square fort, with towers at the angles. In the reign of Charles the Sixth, after the Maillotin insurrection, in 1382, the Bastile was again enlarged, by the addition of two towers at each end of the fortress; thus presenting a front of four towers to the city, and as many to the suburb. To render more difficult any attempt to surprise the place, the road, which, as we have seen, ran through it, was turned to one side. The body of the fortress received no further accession; but, before the middle of the seventeenth century, a bastion was constructed on the side toward the suburb, and a broad dry ditch, about forty yards wide and twelve deep, faced with masonry, encircled the whole. Along the summit of the exterior wall of the ditch, which was at an elevation of sixty feet above the bottom of the ditch, was a wooden gallery, called the Rounds, reached by two flights of steps. Day and night sentinels were constantly moving about in this gallery; every quarter of an hour they were visited by some of the officers or serjeants; and, more completely to secure their vigilance, each man had certain numbered pieces of copper pierced with holes, which, at stated times, he was to drop on the point of an instrument, fixed in a padlocked box. A bell was also rung upon the Rounds, every quarter of an hour, throughout the night. The officers on the establishment of the Bastile consisted of a governor, the king’s lieutenant, a major, who officiated as secretary, and prepared the reports and monthly accounts for the minister, two adjutants to assist him, a physician, a surgeon and his assistant, a chaplain, two priests, and a confessor, a keeper of the records, clerk, superintendant of the buildings, engineer, four turnkeys, and a company of invalids. No soldier was allowed to sleep out of the place without leave from the governor; nor could any officer dine out or be absent all night, without permission from the minister. Originally only the governor and the king’s lieutenant were appointed by the king, the rest being nominated by the governor; and guard was mounted at the castle by a body of citizens, which bore the name of the Independent Company of Archers. The change was made about the middle of the eighteenth century.
