And indeed, had but any considerable body of the foot made an orderly retreat, it had been very probable they had given the enemy a brush that would have turned the scale of victory; for our horse being whole, and in a manner untouched, the enemy found such a check in the pursuit, that 1600 of their forwardest men following too eagerly, fell in with the Rhinegrave's advanced troops the next day, and were cut in pieces without mercy.
This gave us some satisfaction for the loss, but it was but small compared to the ruin of that day. We lost near 8000 men upon the spot, and above 3000 prisoners, all our cannon and baggage, and 120 colours. I thought I never made so indifferent a figure in my life, and so we thought all; to come away, lose our infantry, our general, and our honour, and never fight for it. Duke Bernhard was utterly disconsolate for old Gustavus Horn, for he concluded him killed; he tore the hair from his head like a madman, and telling the Rhinegrave the story of the council of war, would reproach himself with not taking his advice, often repeating it in his passion. "Tis I," said he, "have been the death of the bravest general in Germany;" would call himself fool and boy, and such names, for not listening to the reasons of an old experienced soldier. But when he heard he was alive in the enemy's hands he was the easier, and applied himself to the recruiting his troops, and the like business of the war; and it was not long before he paid the Imperialists with interest.
I returned to Frankfort-au-Main after this action, which happened the 17th of August 1634; but the progress of the Imperialists was so great that there was no staying at Frankfort. The chancellor Oxenstiern removed to Magdeburg, Duke Bernhard and the Landgrave marched into Alsatia, and the Imperialists carried all before them for all the rest of the campaign. They took Philipsburg by surprise; they took Augsburg by famine, Spire and Treves by sieges, taking the Elector prisoner. But this success did one piece of service to the Swedes, that it brought the French into the war on their side, for the Elector of Treves was their confederate. The French gave the conduct of the war to Duke Bernhard. This, though the Duke of Saxony fell off, and fought against them, turned the scale so much in their favour, that they recovered their losses, and proved a terror to all Germany. The farther accounts of the war I refer to the histories of those times, which I have since read with a great deal of delight.
I confess when I saw the progress of the Imperial army, after the battle of Nördlingen, and the Duke of Saxony turning his arms against them, I thought their affairs declining; and, giving them over for lost, I left Frankfort, and came down the Rhine to Cologne, and from thence into Holland.
I came to the Hague the 8th of March 1635, having spent three years and a half in Germany, and the greatest part of it in the Swedish army.
I spent some time in Holland viewing the wonderful power of art, which I observed in the fortifications of their towns, where the very bastions stand on bottomless morasses, and yet are as firm as any in the world. There I had the opportunity of seeing the Dutch army, and their famous general, Prince Maurice. 'Tis true, the men behaved themselves well enough in action, when they were put to it, but the prince's way of beating his enemies without fighting, was so unlike the gallantry of my royal instructor, that it had no manner of relish with me. Our way in Germany was always to seek out the enemy and fight him; and, give the Imperialists their due, they were seldom hard to be found, but were as free of their flesh as we were. Whereas Prince Maurice would lie in a camp till he starved half his men, if by lying there he could but starve two-thirds of his enemies; so that indeed the war in Holland had more of fatigues and hardships in it, and ours had more of fighting and blows. Hasty marches, long and unwholesome encampments, winter parties, counter-marching, dodging and entrenching, were the exercises of his men, and oftentimes killed him more men with hunger, cold and diseases, than he could do with fighting. Not that it required less courage, but rather more, for a soldier had at any time rather die in the field a la coup de mousquet, than be starved with hunger, or frozen to death in the trenches.
Nor do I think I lessen the reputation of that great general; for 'tis most certain he ruined the Spaniard more by spinning the war thus out in length, than he could possibly have done by a swift conquest. For had he, Gustavus-like, with a torrent of victory dislodged the Spaniard of all the twelve provinces in five years, whereas he was forty years a-beating them out of seven, he had left them rich and strong at home, and able to keep them in constant apprehensions of a return of his power. Whereas, by the long continuance of the war, he so broke the very heart of the Spanish monarchy, so absolutely and irrecoverably impoverished them, that they have ever since languished of the disease, till they are fallen from the most powerful, to be the most despicable nation in the world.
The prodigious charge the King of Spain was at in losing the seven provinces, broke the very spirit of the nation; and that so much, that all the wealth of their Peruvian mountains have not been able to retrieve it; King Philip having often declared that war, besides his Armada for invading England, had cost him 370,000,000 of ducats, and 4,000,000 of the best soldiers in Europe; whereof, by an unreasonable Spanish obstinacy, above 60,000 lost their lives before Ostend, a town not worth a sixth part either of the blood or money it cost in a siege of three years; and which at last he had never taken, but that Prince Maurice thought it not worth the charge of defending it any longer.
However, I say, their way of fighting in Holland did not relish with me at all. The prince lay a long time before a little fort called Schenkenschanz, which the Spaniard took by surprise, and I thought he might have taken it much sooner. Perhaps it might be my mistake, but I fancied my hero, the King of Sweden, would have carried it sword in hand, in half the time.
However it was, I did not like it; so in the latter end of the year I came to the Hague, and took shipping for England, where I arrived, to the great satisfaction of my father and all my friends.
