Early in 1757 the Prussian army in Saxony began to move. Through four defiles in the mountains they came pouring into Bohemia. Prague was the King’s first mark; but the ulterior object was probably Vienna. At Prague lay Marshal Brown with one great army. Daun, the most cautious and fortunate of the Austrian captains, was advancing with another. Frederic determined to overwhelm Brown before Daun should arrive. On the sixth of May was fought, under those walls which, a hundred and thirty years before, had witnessed the victory of the Catholic league and the flight of the unhappy Palatine, a battle more bloody than any which Europe saw during the long interval between Malplaquet and Evlau. The King and Prince Ferdinand of Brunswick were distinguished on that day by their valour and exertions. But the chief glory was with Schwerin. When the Prussian infantry wavered, the stout old marshal snatched the colours from an ensign, and, waving them in the air, {220}led back his regiment to the charge. Thus at seventy-two years of age he fell in the thickest battle, still grasping the standard which bears the black eagle on the field argent. The victory remained with the King; but it had been dearly purchased. Whole columns of his bravest warriors had fallen. He admitted that he had lost eighteen thousand men. Of the enemy, twenty-four thousand had been killed wounded, or taken. Part of the defeated army was shut up in Prague. Part fled to join the troops which, under the command of Daun, were now close at hand. Frederic determined to play over the same game which had succeeded at Lowositz. He left a large force to besiege Prague, and at the head of thirty thousand men he marched against Daun. The cautious Marshal, though he had a great superiority in numbers, would risk nothing. He occupied at Kolin a position almost impregnable, and awaited the attack of the King. It was the eighteenth of June, a day which, if the Greek superstition still retained its influence, would be held sacred to Nemesis, a day on which the two greatest princes of modern times were taught, by a terrible experience, that neither skill nor valour can fix the inconstancy of fortune. The battle began before noon; and part of the Prussian army maintained the contest till after the midsummer sun had gone down. But at length the King found that his troops, having been repeatedly driven back with frightful carnage, could no longer be led to the charge. He was with difficulty persuaded to quit the field. The officers of his personal staff were under the necessity of expostulating with him, and one of them took the liberty to say, “Does your Majesty mean to storm {221}the batteries alone?” Thirteen thousand of his bravest followers had perished. Nothing remained for him but to retreat in good order, to raise the siege of Prague, and to hurry his army by different routes out of Bohemia.
