But Providence, which ordained the civilization of Russia, also ordained that the triumphant czar should not be unduly aggrandized, and should himself learn lessons of humility. The Turks, in consequence of the intrigues of Charles, and their hereditary jealousy, made war upon Peter, and advanced against him with an army of two hundred and fifty thousand men. His own army was composed of only forty thousand. He was also indiscreet, and soon found himself in the condition of Charles at Pultowa. On the banks of the Pruth, in Moldavia, he was surrounded by the whole Turkish force, and famine or surrender seemed inevitable. It was in this desperate and deplorable condition that he was rescued by the Czarina Catharine, by whose address a treaty was made with his victorious enemy, and Peter was allowed to retire with his army. Charles XII. was indignant beyond measure with the Turkish general, for granting such easy conditions, when he had the czar in his power; and to his reproaches the vizier of the sultan replied, "I have a right to make peace or war; and our law commands us to grant peace to our enemies, when they implore our clemency." Charles replied with an insult; and, though a fugitive in the Turkish camp, he threw himself on a sofa, contemptuously cast his eye on all present, stretched out his leg, and entangled his spur in the vizier's robe; which insult the magnanimous Turk affected to consider an accident. After the defeat of Peter on the banks of the Pruth, he devoted himself with renewed energy to the improvement of his country. He embellished St. Petersburg, his new capital, with palaces, churches, and arsenals. He increased his army and navy, strengthened himself by new victories, and became gradually master of both sides of the Gulf of Finland, by which his vast empire was protected from invasion.
