With the spring, Charles fell upon the Saxon forces in Livonia, before a fresh league between Augustus and Peter had had time to develop advantageously. After one decisive victory, the Duchy of Courland made submission, and he marched into Lithuania. In Poland, neither the war nor the rule of Augustus was popular, and in the divided state of the country Charles advanced triumphantly. A Polish diet was summoned, and Charles awaited events; he was at war, he said, not with Poland, but with Augustus. He had, in fact, resolved to dethrone the King of Poland by the instrumentality of the Poles themselves--a process made the easier by the normal antagonism between the diet and the king, an elective, not a hereditary ruler. Augustus endeavoured, quite fruitlessly, to negotiate with Charles on his own account, while the diet was much more zealous to curtail his powers than to resist the Swedish monarch, and was determined that, at any price, the Saxon troops should leave Poland. Intrigues were going on on all sides. Presently Charles set his forces in motion. When Augustus learned that there was to be no peace till Poland had a new king, he resolved to fight. Charles's star did not desert him. He won a complete victory. Pressing in pursuit of Augustus, he captured Cracow, but his advance was delayed for some weeks by a broken leg; and in the interval there was a considerable rally to the support of Augustus. But the moment Charles could again move, he routed the enemy at Pultusk. The terror of his invincibility was universal. Success followed upon success. The anti-Saxon party in the diet succeeded in declaring the throne vacant. Charles might certainly have claimed the crown for himself, but chose instead to maintain the title of the Sobieski princes. The kidnapping of James Sobieski, however, caused Charles to insist on the election of Stanislaus Lekzinsky. _II.--From Triumph to Disaster_ Charles left Warsaw to complete the subjugation of Poland, leaving the new king in the capital. Stanislaus and his court were put to sudden flight by the appearance of Augustus with 20,000 men. Warsaw fell at once; but when Charles turned on the Saxon army, only the wonderful skill of Schulembourg saved it from destruction. Augustus withdrew to Saxony, and began repairing the fortifications of Dresden.
