Tilly was now joined with the Duke of Bavaria, and might together make about 22,000 men, and in order to keep the Swedes out of the country of Bavaria, had planted themselves along the banks of the river Lech, which runs on the edge of the duke’s territories; and having fortified the other side of the river, and planted his cannon for several miles at all the convenient places on the river, resolved to dispute the king’s passage.

I shall be the longer in relating this account of the Lech, being esteemed in those days as great an action as any battle or siege of that age, and particularly famous for the disaster of the gallant old General Tilly; and for that I can be more particular in it than other accounts, having been an eye-witness to every part of it.

The king being truly informed of the disposition of the Bavarian army, was once of the mind to have left the banks of the Lech, have repassed the Danube, and so setting down before Ingolstadt, the duke’s capital city, by the taking that strong town to have made his entrance into Bavaria, and the conquest of such a fortress, one entire action; but the strength of the place and the difficulty of maintaining his leaguer in an enemy’s country while Tilly was so strong in the field, diverted him from that design; he therefore concluded that Tilly was first to be beaten out of the country, and then the siege of Ingolstadt would be the easier.

Whereupon the king resolved to go and view the situation of the enemy.  His Majesty went out the 2nd of April with a strong party of horse, which I had the honour to command.  We marched as near as we could to the banks of the river, not to be too much exposed to the enemy’s cannon, and having gained a little height, where the whole course of the river might be seen, the king halted, and commanded to draw up.  The king alighted, and calling me to him, examined every reach and turning of the river by his glass, but finding the river run a long and almost a straight course he could find no place which he liked; but at last turning himself north, and looking down the stream, he found the river, stretching a long reach, doubles short upon itself, making a round and very narrow point.  “There’s a point will do our business,” says the king, “and if the ground be good I’ll pass there, let Tilly do his worst.”

He immediately ordered a small party of horse to view the ground, and to bring him word particularly how high the bank was on each side and at the point.  “And he shall have fifty dollars,” says the king, “that will bring me word how deep the water is.”  I asked his Majesty leave to let me go, which he would by no means allow of; but as the party was drawing out, a sergeant of dragoons told the king, if he pleased to let him go disguised as a boor, he would bring him an account of everything he desired.  The king liked the notion well enough, and the fellow being very well acquainted with the country, puts on a ploughman’s habit, and went
