And it was no more than need; for though we had used all the diligence possible to prevent any notice, yet somebody, more forward than ordinary, had escaped away, and carried news of it to the Imperial army. The general, upon this bad news, detaches Major-General Sparr with a body of 6000 men to cut off our retreat. The king, who had notice of this detachment, marches out in person with 3000 men to wait upon General Sparr. All this was the account of one day. The king met General Sparr at the moment when his troops were divided, fell upon them, routed one part of them, and the rest in a few hours after, killed them 1000 men, and took the general prisoner.
In the interval of this action we came safe to the camp with our booty, which was very considerable, and would have supplied our whole army for a month. Thus we feasted at the enemy's cost, and beat them into the bargain.
The king gave all the live cattle to the Nurembergers, who, though they had really no want of provisions, yet fresh meat was not so plentiful as such provisions which were stored up in vessels and laid by.
After this skirmish we had the country more at command than before, and daily fetched in fresh provisions and forage in the fields.
The two armies had now lain a long time in sight of one another, and daily skirmishes had considerably weakened them; and the king, beginning to be impatient, hastened the advancement of his friends to join him, in which also they were not backward; but having drawn together their forces from several parts, and all joined the chancellor Oxenstiern, news came, the 15th of August, that they were in full march to join us; and being come to a small town called Brock, the king went out of the camp with about 1000 horse to view them. I went along with the horse, and the 21st of August saw the review of all the armies together, which were 30,000 men, in extraordinary equipage, old soldiers, and commanded by officers of the greatest conduct and experience in the world. There was the rich chancellor of Sweden, who commanded as general; Gustavus Horn and John Baner, both Swedes and old generals; Duke William and Duke Bernhard of Weimar; the Landgrave of Hesse-Cassel, the Palatine of Birkenfelt, and abundance of princes and lords of the empire.
The armies being joined, the king, who was now a match for Wallenstein, quits his camp and draws up in battalia before the Imperial trenches: but the scene was changed. Wallenstein was no more able to fight now than the king was before; but, keeping within his trenches, stood upon his guard. The king coming up close to his works, plants batteries, and cannonaded him in his very camp. The Imperialists, finding the king press upon them, retreat into a woody country about three leagues, and, taking possession of an old ruined castle, posted their army behind it.
This old castle they fortified, and placed a very strong guard there. The king, having viewed the place, though it was a very strong post, resolved to attack it with the whole right wing. The attack was made with a great deal of order and resolution, the king leading the first party on with sword in hand, and the fight was maintained on both sides with the utmost gallantry and obstinacy all the day and the next night too, for the cannon and musket never gave over till the morning; but the Imperialists having the advantage of the hill, of their works and batteries, and being continually relieved, and the Swedes naked, without cannon or works, the post was maintained, and the king, finding it would cost him too much blood, drew off in the morning.
This was the famous fight at Altemberg, where the Imperialists boasted to have shown the world the King of Sweden was not invincible. They call it the victory at Altemberg; 'tis true the king failed in his attempt of carrying their works, but there was so little of a victory in it, that the Imperial general thought fit not to venture a second brush, but to draw off their army as soon as they could to a safer quarter.
I had no share in this attack, very few of the horse being in the action, but my comrade, who was always among the Scots volunteers, was wounded and taken prisoner by the enemy. They used him very civilly, and the king and Wallenstein straining courtesies with one another, the king released Major-General Sparr without ransom, and the Imperial general sent home Colonel Tortenson, a Swede, and sixteen volunteer gentlemen, who were taken in the heat of the action, among whom my captain was one.
The king lay fourteen days facing the Imperial army, and using all the stratagems possible to bring them to a battle, but to no purpose, during which time we had parties continually out, and very often skirmishes with the enemy.
