A dangerous debtor in such matters, this Karl Gustav. In these same months, busy with the Danish part of the Controversy, he was doing a feat of war which set all Europe in astonishment. In January, 1658, Karl Gustav marches his Army, horse, foot, and artillery, to the extent of Twenty thousand, across the Baltic ice, and takes an island without shipping--Island of Fuenen, across the Little Belt--three miles of ice, and a part of the sea _open_, which has to be crossed on planks; nay, forward from Fuenen, when once there, he achieves ten whole miles more of ice, and takes Zealand itself, to the wonder of all mankind: an imperious, stern-browed, swift-striking man, who had dreamed of a new Goth Empire: the mean Hypocrites and Fribbles of the South to be coerced again by noble Norse valor, and taught a new lesson; has been known to lay his hand on his sword while apprising an Embassador (Dutch High Mightiness) what his royal intentions were: "not the sale or purchase of groceries, observe you, Sir! My aims go higher." Charles XII's Grandfather, and somewhat the same type of man. But Karl died short while after; left his big, wide-raging Northern Controversy to collapse in what way it could. Sweden and the fighting parties made their "Peace of Oliva" (Abbey of Oliva, near Dantzig, May 1, 1660), and this of Preussen was ratified, in all form, among other points. No Homage more; nothing now above Ducal Prussia but the Heavens, and great times coming for it. This was one of the successfulest strokes of business ever done by Friedrich Wilhelm, who had been forced, by sheer compulsion, to embark in that big game. "Royal Prussia," the Western _Polish_ Prussia--this too, as all Newspapers know, has in our times gone the same road as the other, which probably after all, it may have had in Nature, some tendency to do? Cut away, for reasons, by the Polish sword, in that Battle of Tannenberg, long since, and then, also for reasons, cut back again: that is the fact, not unexampled in human History. Old Johann Casimir, not long after that Peace of Oliva, getting tired of his unruly Polish chivalry and their ways, abdicated, retired to Paris, and "lived much with Ninon de l'Enclos and her circle" for the rest of his life. He used to complain of his Polish chivalry that there was no solidity in them, nothing but outside glitter, with tumult and anarchic noise; fatal want of one essential talent, the talent of Obeying; and has been heard to prophesy that a glorious Republic, persisting in such courses, would arrive at results which would surprise it.
