So the boy conqueror entered upon his career of victory. Space does not permit to detail his battles and his conquests. How he placed a new king on the throne of Poland, kept Denmark in submission, held the hosts of Russia at bay, humbled Austria, and made his name, ere yet he was twenty, at once a wonder and a terror in all the courts of Europe. How, at last, his ambition getting the better of his discretion, he thought to be a modern Alexander, to make Europe Protestant, subdue Rome, and carry his conquering eagles into Egypt and Turkey and Persia. How, by unwise measures and foolhardy endeavors, he lost all the fruits of his hundred victories and his nine years of conquest in the terrible defeat by the Russians at Pultowa, which sent him an exile into Turkey, kept him there a prisoner of state for over five years; and how, finally, when once again at the head of Swedish troops, instead of defending his own home-land of Sweden, he invaded Norway in the depth of winter, and was killed, when but thirty-six, by a cannon-shot from the enemy's batteries at Frederickshall on December 11, 1718. Charles the Twelfth of Sweden was one of the most remarkable of the world's historic boys. Elevated to a throne founded on despotic power and victorious memories, at an age when most lads regard themselves as the especial salt of the earth, he found himself launched at once into a war with three powerful nations, only to become in turn the conqueror of each. A singularly good boy, so far as the customary temptations of power and high station are concerned--temperate, simple, and virtuous in tastes, dress, and habits--he was, as one of his biographers has remarked, "the only one among kings who had lived without a single frailty." But this valorous boy, who had first bridled his own spirit, and then conquered the Northern world, "reared," as has been said, "under a father cold and stern, defectively educated, taught from childhood to value nothing but military glory," could not withstand the temptation of success. An ambition to be somebody and to do something is always a laudable one in boy or girl, until it supplants and overgrows the sweet, true, and manly boy and girl nature, and makes us regardless of the comfort or the welfare of others. A desire to excel the great conquerors of old, joined to an obstinacy as strong as his courage, caused young Charles of Sweden to miss the golden opportunity, and instead of seeking to rule his own country wisely, sent him abroad a homeless wanderer on a career of conquest, as romantic as it was, first, glorious, and at the last disastrous.
