A week before Nigel had ridden into Tilly's camp, much to the old general's surprise.

"I had thought Wallenstein would have clapped hands upon you to command a brigade!"

"I am not rich enough!" said Nigel. "Besides, who knows whether he will be needed."

"H'm!" was the old general's comment. "If old Tilly gets knocked on the head he will be needed, and soon. But what am I to do with you? Had you brought me three or four regiments now! Said there was a lack of officers, did they? Fools! Of captains and lieutenants? Yes! They have a habit of getting killed! Of colonels even I lack one or two, but of generals! I warrant Gustavus has not half as many. 'Tis the way of Imperial armies!"

"'Tis no matter what I am called!" said Nigel. "Give me a regiment. I am content to be called 'Colonel.' Give me a chance of having at them, sword, musket, gun, anyhow."

"You shall stand just as good a chance of getting killed as I do," grunted the Count.

Nigel was satisfied. The old general's thirst for danger was well known, and he had not forgotten Breitenfeld. Presently Count Tilly assigned him his command. It was a small brigade, comprising three regiments of musketeers and two batteries of ten pieces each. One of the regiments had just lost its colonel, the colonels of the other two were but young in experience, and had but recently been promoted.

The artillery was commanded by a major, who, Tilly said, might be relied upon to handle his pieces and his men in a soldier-like fashion, but had no head for tactics. This Nigel was to supply. Nigel's lines were well up the Lech towards the little town of Rain, and the northern angle of the triangle that formed the whole position of the camp.

For some days at least Nigel did nothing but drill and exercise his little force, make himself acquainted with his officers, and make reconnaissances along the road by which Gustavus must come.

The next best thing to a solitary hill-top for descrying an advancing host is a church spire, and one such, in a village some ten Scots miles from Rain, and a mile or two off the road to Donauwerth, Nigel had marked for a look-out tower.
