At length appeared the new Swedish generalissimo, with fresh troops and money. This was Bernard Torstensohn, a pupil of Gustavus Adolphus, and his most successful imitator, who had been his page during the Polish war. Though a martyr to the gout, and confined to a litter, he surpassed all his opponents in activity; and his enterprises had wings, while his body was held by the most frightful of fetters. Under him, the scene of war was changed, and new maxims adopted, which necessity dictated, and the issue justified. All the countries in which the contest had hitherto raged were exhausted; while the House of Austria, safe in its more distant territories, felt not the miseries of the war under which the rest of Germany groaned. Torstensohn first furnished them with this bitter experience, glutted his Swedes on the fertile produce of Austria, and carried the torch of war to the very footsteps of the imperial throne. In Silesia, the enemy had gained considerable advantages over the Swedish general Stalhantsch, and driven him as far as Neumark. Torstensohn, who had joined the main body of the Swedes in Lunenburg, summoned him to unite with his force, and in the year 1642 hastily marched into Silesia through Brandenburg, which, under its great Elector, had begun to maintain an armed neutrality. Glogau was carried, sword in hand, without a breach, or formal approaches; the Duke Francis Albert of Lauenburg defeated and killed at Schweidnitz; and Schweidnitz itself with almost all the towns on that side of the Oder, taken. He now penetrated with irresistible violence into the interior of Moravia, where no enemy of Austria had hitherto appeared, took Olmutz, and threw Vienna itself into consternation. But, in the mean time, Piccolomini and the Archduke Leopold had collected a superior force, which speedily drove the Swedish conquerors from Moravia, and after a fruitless attempt upon Brieg, from Silesia. Reinforced by Wrangel, the Swedes again attempted to make head against the enemy, and relieved Grossglogau; but could neither bring the Imperialists to an engagement, nor carry into effect their own views upon Bohemia. Overrunning Lusatia, they took Zittau, in presence of the enemy, and after a short stay in that country, directed their march towards the Elbe, which they passed at Torgau. Torstensohn now threatened Leipzig with a siege, and hoped to raise a large supply of provisions and contributions from that prosperous town, which for ten years had been unvisited with the scourge of war.
