THREE:On the River Maas, a few miles north of the present city of Liege, there was a celebrated castle called Herstal. For many generations feudal lords had there displayed their pomp and power; and it had been the theatre not only of princely revelry, but of many scenes of violence and blood. A surrounding territory of a few thousand acres, cultivated by serfs, who were virtually slaves, was the hereditary domain of the petty lords of the castle. A few miles south of the castle there was a monastery called Liege, which was a dependency of the lords of Herstal.��Moravia, which is a very bad country, could not be held, owing to want of provisions. The town of Brünn could not be taken because the Saxons had no cannon. When you wish to enter a town, you must first make a hole to get in by. Besides, the country has been reduced to such a state that the enemy can not subsist in it, and you will soon see him leave it. There is your little military lesson. I would not have you at a loss what to think of our operations, or what to say, should other people talk of them in your presence.��
