Gustav Adolf had arrived not a moment too soon. The huge army which Wallenstein had assembled in Bohemia was marching on the city. Sixty thousand strong, that army was-the largest force ever put into the field in the course of the long and brutal war. Tilly's Bavarian troops, now under the direct command of the Elector Maximillian, were marching to join him-perhaps another twenty thousand men. And Pappenheim, whose Black Cuirassiers had spent the spring and early summer in Westphalia, was reported to be coming as well. Pappenheim's route was unclear, but the Swedes assumed he would take advantage of Gustav's withdrawal to Nьrnberg to march through Franconia. If so, Nьrnberg was threatened from three sides: Wallenstein from the northeast, Maximillian from the south, Pappenheim from the west. An army of one hundred thousand men was about to threaten Nьrnberg with the fate suffered by Magdeburg.
While the inhabitants of the city frantically erected their fortifications, under the direction of the Swedish engineer Hans Olaf, Gustav had led his army back into the field. For days, the Swedes had maneuvered against the oncoming enemy forces, slowing their advance and buying time for Nьrnberg. But on July 10, at Neumarkt, the Bavarian and imperial armies had finally merged.
Although he was outnumbered four to one, Gustav had continued to challenge Wallenstein to meet him in the open field. Wallenstein had declined. The Bohemian military contractor preferred the surer, if slower, methods of siege warfare. Steadily, surely, inexorably, his enormous army had moved into positions threatening the city. But, by then, the feverish program of fortifications had erected a new wall around Nьrnberg, replacing the inner walls of the city. Gustav's line of defense, hastily erected but well designed, was too large for even Wallenstein to surround.
So, the Bohemian had been forced to "besiege" Nьrnberg by erecting what amounted to a "counter-city." Through the rest of July, Wallenstein's men had been set to work erecting a gigantic armed camp a few miles to the southwest of the city. Using the Bibert River as a central water supply, Wallenstein had erected fieldworks with a circumference of a dozen miles. The strong point in those fieldworks, directly facing the Swedes, was a wooded hill on the north. That hill was called the Burgstall. It rose some two hundred and fifty feet above the Rednitz river, flowing past its eastern slope. In effect, the Rednitz served as a moat, and the wooded hill was capped by an ancient ruined castle named the Alte Veste. Wallenstein had turned the Alte Veste and the entire Burgstall into a fortress. Palisades and ditches sprouted like mushrooms on the hill, with clear lines of fire for the heavy guns positioned on its slopes.
Then-nothing. Time after time, Gustav had sallied from Nьrnberg, challenging Wallenstein to open battle. Wallenstein declined. "There has been enough fighting," he told his generals. "I will show them another method."
Cold-blooded like no man of his time, Wallenstein's method was simple. Hunger and disease, soon enough, would strike both armies. Men would die in the thousands, and then the tens of thousands-and he had a lot more men than the king of Sweden.
"Treason," whispered Gustav. "It can only be treason."
Torstensson frowned. He detested the younger duke of Saxe-Weimar, true. But-treason?
"I can't-" The young general hesitated. "I'm afraid I can't see the logic of that, Your Majesty." He pointed to the west. "It's true that Bernard's left the door open for the Spaniards, if they choose to come through. But even if that's his purpose, what's the point? The Lower Palatinate is still blocked. For a Spanish army to threaten us, they'd have to-" He stumbled to a halt, his eyes widening.
The king nodded. "March through Thuringia," he concluded grimly. "Which, of course, would be an incredibly roundabout way of threatening Nьrnberg. But what if they have no intention of coming this far? What if, Lennart, their purpose is not to march through Thuringia, but simply to attack it?"
Torstensson's head swiveled. He was staring north, now, instead of west. "Maybe," he mused. "That, at least, would make Bernard's maneuvers sensible-assuming he is committing treason." Torstensson squinted. "But, even so-what's the point?"
The artillery general's shoulders twitched. The gesture was more an expression of exasperation than a shrug. "I have never seen the Americans in action. But judging from every report we've gotten-and I've heard Mackay myself-they can shatter any army which comes at them directly. Especially those hide-bound Spanish tercios."
The king snorted. "Yes. But ask yourself this, Lennart-has anyone told the Spaniards?"
Now, Torstensson's eyes were very wide. Like all of Sweden's top commanders, Torstensson was privy to the complex and tortuous diplomatic maneuvers which his king had been forced to engage in over the past two years.
"Richelieu," he murmured.
Gustav nodded. "That would be the conduit, sure enough. Richelieu has the money, and the patronage, to offer Bernard an exceptional price for turning his coat. Alsace, probably, to replace his precious Thuringia. Or Lorraine. A word to the Spanish-who have been chafing to get into Germany for years, on any pretext-and there we have it. An open road for a Spanish army from the Low Countries to strike at Thuringia."
"But Richelieu's been trying to keep the Spanish out of Germany since he took office," protested Torstenson. The protest was feeble, however. The quick-witted artillery general was already working through the logic. He began stroking his beard, thinking aloud: "Hostility to Spain has been the keystone of his foreign policy, true enough. But now that your position in central Europe has become so strong, he may be thinking of a counterweight."
"Precisely. And ask yourself-why has my position grown so strong?" Gustav made a little dismissive gesture with his hand. "Not my army. Richelieu is a money man, not a soldier. To him, bullion rules the world."
Torstensson's beard stroking grew vigorous. "Yes. Yes. Thuringia's the key to that, too. As long as the Americans hold it firmly, we have a secure logistics base and a reliable source of cash. It's made us completely independent of any foreign pursemasters." His lips pursed. "Well-it will, I should say. Take a few months before everything settles in. But Richelieu is a man to think ahead, if ever one lived."
He dropped his hand from the beard and turned to face his king squarely. "But I still don't see what Richelieu hopes to accomplish. Unless he simply wants to see a Spanish army battered and bleeding."
Gustav grinned humorlessly. "He certainly wouldn't lose any sleep over that." The king shrugged. "I don't understand the logic myself, Lennart. But I can smell it. Something's up."
He paused for a few seconds. Then, slowly, a wicked smile began spreading across his face. His blue eyes seemed to dance and sparkle.
"The very thing!" he exclaimed. He planted his hands on his hips and, grinning now, said to Torstensson: "I believe we should send a small expedition to Thuringia to investigate. And I know just the man to lead it!"
Torstensson frowned. "Who? One of the Scottish colonels? Or perhaps-" The meaning of that wicked gleam in his king's eye finally registered. Torstensson's own eyes almost bulged. "Not-"
"The very man!" cried the king gaily. "Captain Gars!" He clapped his hands. "He'll be ecstatic at the prospect, too-I can assure you of that. Captain Gars is every bit as sick of this miserable siege as I am. And there's plenty of time for him to go and come back before anything happens."
