"I fancy I shall join the king tomorrow, doctor."

"Tomorrow?" the surgeon repeated in surprise.

"Yes, sir. Have you not heard the news? The king is marching with all speed this way. I do not know what his intention is--to force Lacy to give battle single handed before Daun can arrive, or to besiege Dresden--but in the city they believe that they are going to be besieged."

"This is news indeed," the surgeon said. "The scouts brought in word this morning that a considerable force was seen, coming along the road from Bautzen. It must be Lacy's army."

"We may be sure that the king is pretty close at his heels," Fergus said. "I have no doubt that by tomorrow morning we shall have news of him, and I fancy that I shall not have far to ride to join him."

The opinion was justified. That evening Lacy joined the Confederate army, in their strong position behind the gap of Plauen. He had been hotly chased, indeed. Frederick had been manoeuvring to pass Daun and carry on a campaign in Silesia; but the Austrian general had been too cautious, and it was impossible to pass him without fighting; so on the night of the 8th he left Bautzen suddenly and silently, and marched all night, in hopes of catching Lacy at Godau. The latter's Croats, however, brought him news in time, and he at once retreated.

After a short halt the Prussians pressed on for another eighteen miles, capturing some of Lacy's hussars, but failing to come up with his main body; which, marching all that day and the next night, arrived near Dresden on the morning of the 10th, Lacy himself reaching the town the evening before. By Thursday evening the whole of his army had crossed Dresden bridge and got in safely behind Plauen, leaving ten thousand men to aid the four thousand in the garrison.

At noon Fergus, hearing that, without doubt, the whole of the enemy had fallen back, started with Karl; and that evening rode into the royal camp, and reported himself to the king.

"I am glad to see you back, Drummond," Frederick said heartily. "I have sorely missed you; and indeed, when I rode away the accounts of you were so bad that I doubted whether you would ever be able to be with me again. You don't look quite yourself yet, but no doubt the air and exercise will soon bring you round. Have you any news?"

"Lacy has left ten thousand men in Dresden, sire, and with the rest of his force has joined the Confederate army at Plauen."
