Baron Garnier, whatever his crimes, had certainly understood the art of war. He rebuilt St. Aliquis in a thoroughly scientific manner, employing a learned masterbuilder and "sage," an elderly Fleming who had seen the best fortifications of the Infidels and had lived long in those famous Syrian-Christian fortresses like Krak des Chevaliers, which by the mere excellence of construction had enabled small garrisons of western "Franks" to defy the full power of Saladin. Instead of a mere ditch, palisade, and then a single vast tower, St. Aliquis has consequently become a huge complex of defenses within defenses, each line of resistance a little harder to penetrate and with every outwork commanded by an inner fortification. If at last you come to the central donjon, it still looms up above you—defiant and formidable, and you can have your fill of desperate fighting, only perhaps to be bloodily repulsed in the end. Of course, the donjon can indeed be starved out, but it is not very often that any enemy of St. Aliquis will have resources and persistence enough to keep his troops together until the castle supplies are exhausted. He must either get possession pretty quickly or not at all—and Garnier's Fleming certainly took pains he should not get in quickly!
In examining St. Aliquis or its rivals, one must remember that they are the creations of men who have devoted most of their thought to the problems of war. Every possible contingency has been anticipated. The architect and his employer have practically spent their lives studying "how can a castle be made to hold out as long as possible?" Being, despite their sins, highly intelligent men, it is not surprising that they produce remarkable results.
We are approaching the castle as the morning mists are lifting from the Claire and the Rapide. Ahead of us, out of the dispersing fog, is rising what seems a bewildering mass of towers, walls, battlements gray and brown, with here and there a bit of green, where a little earth has been allowed to lodge and a few weeds shoot forth. High above all soars the mass of the great central tower, the donjon, from the summit of which Baron Conon's banner is now idly trailing.
We come down a road that takes us over the toll bridge across the Rapide and find ourselves in a kind of parade ground where there are only a few cattle sheds and possibly a rude cabin or two for such of the baron's herdsmen as must sleep outside overnight. This open ground is the scene for martial exercises, rallyings of the vassals, and even for tournaments. Many people are headed toward the castle, mostly from the village of peasants just westward across the river; but there is also the subprior on a mule, riding over from the abbey, and also a messenger who has spurred down very early from Pontdebois with a communication from the bishop. As we near the castle its tower and inner and outer wards become more distinct. We readily believe that it took Garnier's architect three years to carry through the work; that all the peasants of the barony had been put to grievous corvées (forced labor) digging, hewing and dragging stone, or working the great derricks; and that ten expert stonecutters and fully eighty less skilled masons had been hired in from Paris, Rheims, and Orléans, besides a master mason who demanded rewards that seemed outrageous for a mere villein and not for a belted knight.
The Barbican and Lists
These speculations end as we come, not to the castle, but to a semicircular palisade inclosing the regular gate on the landward side. This palisade is too high to scramble over; the piles are too sharply pointed and stout enough to stand considerable battering. This outwork is the barbican—the first of the long series of obstacles awaiting the foe. Of course, it could not be defended in a regular siege, but its purpose is to stop any surprise attack long enough to enable the garrison to rally, close the great gate, and man the walls. The whole crowd of folk now entering make for the heavy wooden barrier which is just being thrown open by a rather sleepy porter. Since it is a time of profound peace, he lets them all stream inside, merely requiring everyone to leave his weapons in his custody. We pass unchallenged, thanks to the kind fée aforementioned, who has rendered us as invisible as the owner of Gyges's ring. If, however, we had been guests of noble rank, we would have proceeded onward to the inner gate and rung loudly on a heavy metal gong hanging there. One of the baron's squires would then have greeted us. If we had been the baron's equal or superior in the social scale, Conon himself would next have come down to lead us in; if somewhat inferior, we would have been conducted by the squire to the great hall, where we would have removed hood and gloves before the magnate presented himself. But we have much to examine ere we penetrate the seigneurial hall.
Once inside the barbican, one discovers that between this extreme barrier and the fortress proper there is another open space with a road, and another place for equestrian exercises extending from the Claire straight over to the abrupt slopes of the Rapide. The palisades run all the way from river to river. This space within the barbican forms the lists, where two young sergeants are breaking in a balky stallion. The lists are a great convenience in peace time, but the real utility is in war, and they are even more important in the castles that have land on every side. They supply a good road by which men can be hurried round the castle circuit in reasonable safety. On the other hand, if the enemy suddenly forces the barriers, he finds himself most awkwardly in a limited space between the palisade and the castle moat, with all the arbalists (crossbows) playing on him from the walls above.
Inside the lists and next to the masonry walls runs the moat. It is some twenty feet wide, partly filled now with scum-covered rain water. In the spring the varlets have great joy here hunting frogs, but as the year advances it assuredly breeds mosquitoes. It constitutes, however, another formidable barrier to an enemy, and that is its sole object.
After crossing these lists, the path leads straight to the drawbridge. This has just been lowered by means of heavy counterpoises swung on a kind of trestle overhead, for even in peace times no seigneur will sleep soundly before the drawbridge is up. The portcullis, the frame of iron bars which is lowered whenever the bridge is raised, has also been hoisted in its groove by the gateway. The heavy oaken gates, faced with metal, have not been unbarred, however. A smaller door, just big enough for a horse, has been opened in one of them, admitting to the castle proper. Despite the earlier scrutiny at the barbican, one now catches a watchful eye at the small window in the turret close beside the portcullis. The chief porter has a very responsible position. Many a fortress has been lost because he has been careless or unfaithful. He would, in any case, be chargeable if he admitted unwelcome guests or idle rascals. Porters are often accused of being gruff, insolent, fat, and lazy, but part of their bad name comes because they have to repel bad characters.
