No words can portray the stupefaction and rage of Sir Rudolph when a man who had managed to slip unobserved from the castle at the time of its capture, bore the news to him in the forest. All opposition there had ceased, and the whole of the troops were engaged in aiding the peasants in cutting wide roads through the trees across the forest, so as to make it penetrable by horsemen in every direction. It was supposed that the outlaws had gradually stolen away through the thickets and taken to the open country, intending to scatter to their homes, or other distant hiding-places; and the news that they had by a ruse captured the castle, came as a thunderclap. Sir Rudolph's first impulse was to call his men together and to march towards the castle. The drawbridge was up, and the walls bristled with armed men. It was useless to attempt a parley; still more useless to think of attacking the stronghold without the proper machines and appliances. Foaming with rage, Sir Rudolph took possession of a cottage near, camped his men around and prepared for a siege. There were among the mercenaries many men accustomed to the use of engines of war. Many, too, had aided in making them; and these were at once set to work to construct the various machines in use at that time. Before the invention of gunpowder, castles such as those of the English barons were able to defy any attack by an armed force for a long period. Their walls were so thick that even the balistas, casting huge stones, were unable to breach them except after a very long time. The moats which surrounded them were wide and deep, and any attempt at storming by ladders was therefore extremely difficult; and these buildings were consequently more often captured by famine than by other means. Of provisions, as Sir Rudolph knew, there was a considerable supply at present in the castle, for he had collected a large number of bullocks in order to feed the strong body who had been added to the garrison. The granaries, too, were well stored; and with a groan Sir Rudolph thought of the rich stores of French wines which he had collected in his cellars.
