The Imperialists had, in the mean time, by slow marches, advanced to Neumark, where Wallenstein made a general review. At the sight of this formidable force, he could not refrain from indulging in a childish boast: "In four days," said he, "it will be shown whether I or the King of Sweden is to be master of the world." Yet, notwithstanding his superiority, he did nothing to fulfil his promise; and even let slip the opportunity of crushing his enemy, when the latter had the hardihood to leave his lines to meet him. "Battles enough have been fought," was his answer to those who advised him to attack the King, "it is now time to try another method." Wallenstein's well-founded reputation required not any of those rash enterprises on which younger soldiers rush, in the hope of gaining a name. Satisfied that the enemy's despair would dearly sell a victory, while a defeat would irretrievably ruin the Emperor's affairs, he resolved to wear out the ardour of his opponent by a tedious blockade, and by thus depriving him of every opportunity of availing himself of his impetuous bravery, take from him the very advantage which had hitherto rendered him invincible. Without making any attack, therefore, he erected a strong fortified camp on the other side of the Pegnitz, and opposite Nuremberg; and, by this well chosen position, cut off from the city and the camp of Gustavus all supplies from Franconia, Swabia, and Thuringia. Thus he held in siege at once the city and the King, and flattered himself with the hope of slowly, but surely, wearing out by famine and pestilence the courage of his opponent whom he had no wish to encounter in the field.
