Early in the year 1740 "Old Fritz" lay on his death-bed, and was able to say, as he put his arms round the Prince's neck, that he was content to die, knowing that he was leaving behind him so worthy a son and successor. Thus Frederick became King of Prussia in his twenty-eighth year. His subjects thought that he would prove a gentle and easy-going king; but imagine their surprise when they found that, like Prince Hal, he bade farewell to his companions and completely turned over a new leaf. "No more of these fooleries," he said, and at once flung himself into the work of making his army as strong and efficient as possible. The men were drilled without mercy, and the officers frequently beat them with canes; but in spite of this treatment they were full of spirit, and in after years showed great valour on the battlefield. Frederick was soon looking about for an opportunity of testing them in war. A few months after he came to the throne, Charles VI., the Holy Roman Emperor, died, and there was no son to succeed him. He left his great dominions--Austria, Hungary, Bohemia, parts of the Netherlands, and parts of North Italy--to his daughter, Maria Theresa,[32] and before his death he had persuaded the sovereigns of Europe to support her as Empress. Amongst those who faithfully promised to do so was Frederick; but I am sorry to say that, very shortly after Maria Theresa ascended her throne, he suddenly assembled his army and marched at its head into her country. He broke his plighted word; he fell upon a state which he thought was unable to defend itself; and he plunged Europe into a long and terrible war, simply because he was eager to increase his power and make people talk about him. You cannot think of a baser crime than this. Frederick used to say: "He is a fool, and that nation is a fool, which, having the power to strike his enemy unawares, does not strike and strike his deadliest." It was the depth of winter when Frederick set his armies in motion. Poor Maria Theresa was taken unawares; town after town yielded, until, before the end of January 1741, Frederick was master of Silesia,[33] and was able to return to Berlin, where he was received with joy by his subjects. Then some of the other greedy sovereigns followed Frederick's bad example, and soon all Europe was in arms. [Illustration: Maria Theresa and the Hungarian Nobles. When Frederick the Great was about to invade Silesia, Maria Theresa, holding her young son in her arms, begged the Hungarian nobles to fight for her. With one accord they drew their swords and cried, "Let us die for our _king_, Maria Theresa!"]
