Walter's first step on assuming the command was to examine thoroughly into the capabilities of defence of the place, to see that the well was in good order, and the supply of water ample, and to send out a foraging party, which, driving in a number of beasts and some cart-loads of forage, would supply his garrison for some time. The castle he found was less strong than it looked. The walls were lightly built, and were incapable of withstanding any heavy battering. The moat was dry, and the flanking towers badly placed, and affording little protection to the faces of the walls; however, the extent of the defences was small, and Walter felt confident that with the force at his command he could resist any sudden attack, unless made in overwhelming force, so that all the faces of the wall could be assaulted at the same time. He had a large number of great stones brought in to pile against the gate, while others were brought into the central keep, similarly to defend the door should the outer wall be carried. He appointed Ralph as his lieutenant, and every day, leaving him in charge of the castle, rode through the country for many miles round, with twenty men-at-arms, to convince himself that no considerable force of the enemy were approaching. These reconnaissances were not without some danger and excitement, for several times bodies of the country people, armed with scythes, axes, and staves, tried to intercept them on their return to the castle, and once or twice Walter and his men had to fight their way through their opponents. Contrary to the custom of the times, Walter gave orders to his men not to slay any when resistance had ceased. “They are but doing what we ourselves should do did French garrisons hold our castles at home, and I deem them in no way to be blamed for the efforts which they make to slay us. In self-defence, of course, we must do our best, and must kill in order that we may not ourselves be slain; but when they are once routed, let them go to their homes. Poor people, the miseries which this war has brought upon them are great, and there is no wonder that they hate us.”
