The watchman of Fougeray saw them dimly in the distance, and rang the bell, to give the alarm, but all fear vanished when it was seen that only wood-cutters were coming towards the castle. Bertrand advanced to the drawbridge, and asked the porter if he did not want wood. The porter said that he did, and not suspecting any harm, let down the drawbridge at once. Du Guesclin laid down his heavy load of wood so as to prevent the bridge from being drawn up, and rushed on to the castle, shouting "Guesclin," the war cry which afterwards became so terrible to his enemies. His comrades followed quickly at his summons; the unhappy porter fell wounded in the struggle, and as there were a hundred men in the place and Bertrand had only sixty when all had come to his aid, the conflict was very sharp; women and children even throwing showers of stones on the heads of the Bretons. Du Guesclin himself was severely wounded, and was found defending himself to the last, without his hatchet, when a party of cavalry belonging to Charles de Blois came up in time to secure possession of the castle. The whole affair may have been considered an ingenious trick, but I think it would have been more noble for Bertrand to have ridden up openly to his enemies, clad in his armour, and with his sword in his hand, than to have deceived them by the woodcutter's guise.

The war went on, and at last the King of England sent Henry, the good Duke of Lancaster, to Bretagne at the head of a large force, with orders to lay siege to Rennes, the city where Bertrand had passed the happiest days of his boyhood, and which had twice been the scene of his triumphs. Besides all the great English nobles who had accompanied the duke, the army was increased by many Breton gentlemen who had enlisted themselves on the side of Jean de Montfort, and Lancaster made a solemn vow not to depart from Rennes until he had planted his standard upon its walls.

Bertrand concealed himself in a forest near the city, and constantly harassed his enemies by rushing suddenly upon them, by day and by night, and always to the cry of "Guesclin," until at last the Duke of Lancaster swore that if ever the brave Breton captain fell into his hands, he would never let him free, however large a ransom might be offered for him.

Lancaster made several attempts upon Rennes, but with little success. One day an English officer who had been captured by Du Guesclin, told him that his countrymen intended to undermine the city and open a breach. Upon this news Bertrand contrived one very dark night to glide with his Bretons into the midst of the English camp, where all was silent, and set fire to some of the tents. The enemy, awakened by the usual cry of "Guesclin," thought that Charles de Blois had fallen upon them with his army, and were very angry as they put out their fires to find it was only Bertrand with his handful of men.

The governor of Rennes now gave orders that in all the houses near the ramparts little copper basins should be hung with one or two balls of brass in each, so that by the jingling of the metal, which the movement of the miners would cause, it might be known in what direction they were at work. By this means the garrison were enabled to work against them until the mine was pierced, and the besiegers found a body of troops ready to beat them back.

The Duke of Lancaster now thought of another plan for subduing the people of Rennes. Knowing that they were almost without provisions, he caused two thousand pigs to be assembled in a field near the walls of the city, hoping that the hungry inhabitants would come out for the purpose of capturing them. The governor, however, was not to be outwitted, and had a sow attached by a rope to the gate of Rennes, with its head downwards. The sow struggled so hard to free itself and grunted and squeaked so loud that the other pigs were naturally attracted to the spot. When the besieged saw that the pigs were coming in that direction they lowered the drawbridge, and cut the rope. The sow, thus released, ran joyfully back into the city, followed by all the other pigs, and it was certain that the famished people of Rennes had a good meal that day and for many days after.

Du Guesclin performed numerous acts of daring during the siege, and one day, when the Bretons had eaten up the two thousand pigs and were very near dying of hunger again, he intercepted and captured a hundred waggons, loaded with wine, flour, and salt meat, which were on their way to the English camp; but when he found that the waggoners were supplying these provisions to the enemy at their own cost, he paid them liberally for all that he had seized.

The Duke of Lancaster now prepared a huge machine which was often used in those times of warfare. This was a wooden tower on wheels, as high as the walls of the city, which contained a number of men inside, who shot surely from it with their arrows. The tower would have caused great havoc, had not Bertrand one night crawled out with his Bretons, and completely destroyed it by fire.

Winter was now coming on: the lengthened siege had lost the lives of many brave men, and Henry of Lancaster at last sent a herald to Du Guesclin to tell him that he desired to speak with him. The herald brought a written passport which, alas! Bertrand was obliged to have read to him by one of his comrades. He had always been so heedless and disobedient in the old days at La Motte, that no one had been able to teach him to read or write, and he had never succeeded in learning in after years, although some authors assert that he could really sign his name.

Bertrand dismissed the herald with a handsome present of clothes and money, and then repaired to the camp of the brave English duke. When there he was asked by Lancaster, whom he owned for his master. "Charles de Blois," he replied promptly, "to whom Bretagne belongs in right of his wife."
