I sent my man express with the king’s answer and the commission to my father, who had the regiment completed in less than two months’ time, and six of the officers, with a list of the rest, came away to me, whom I presented to his Majesty when he lay before Nuremberg, where they kissed his hand.

One of the captains offered to bring the whole regiment travelling as private men into the army in six weeks’ time, and either to transport their equipage, or buy it in Germany, but ’twas thought impracticable.  However, I had so many come in that manner that I had a complete troop always about me, and obtained the king’s order to muster them as a troop.

On the 8th of March the king decamped, and, marching up the river Maine, bent his course directly for Bavaria, taking several small places by the way, and expecting to engage with Tilly, who he thought would dispute his entrance into Bavaria, kept his army together; but Tilly, finding himself too weak to encounter him, turned away, and leaving Bavaria open to the king, marched into the Upper Palatinate.  The king finding the country clear of the Imperialists comes to Nuremberg, made his entrance into that city the 21st of March, and being nobly treated by the citizens, he continued his march into Bavaria, and on the 26th sat down before Donauwerth.  The town was taken the next day by storm, so swift were the conquests of this invincible captain.  Sir John Hepburn, with the Scots and the English volunteers at the head of them, entered the town first, and cut all the garrison to pieces, except such as escaped over the bridge.

I had no share in the business of Donauwerth, being now among the horse, but I was posted on the roads with five troops of horse, where we picked up a great many stragglers of the garrison, whom we made prisoners of war.

’Tis observable that this town of Donauwerth is a very strong place and well fortified, and yet such expedition did the king make, and such resolution did he use in his first attacks, that he carried the town without putting himself to the trouble of formal approaches.  ’Twas generally his way when he came before any town with a design to besiege it; he never would encamp at a distance and begin his trenches a great way off, but bring his men immediately within half musket-shot of the place; there getting under the best cover he could, he would immediately begin his batteries and trenches before their faces; and if there was any place possibly to be attacked, he would fall to storming immediately.  By this resolute way of coming on he carried many a town in the first heat of his men, which would have held out many days against a more regular siege.

This march of the king broke all Tilly’s measures, for now he was obliged to face about, and leaving the Upper Palatinate, to come to the assistance of the Duke of Bavaria; for the king being 20,000 strong, besides 10,000 foot and 4000 horse and dragoons which joined him from the Duringer Wald, was resolved to ruin the duke, who lay now open to him, and was the most powerful and inveterate enemy of the Protestants in the empire.
