It seemed that the King's distress could hardly be increased. Yet at this moment another blow not less terrible than that of Kolin fell upon him. The French under Marshal D'Estrées had invaded Germany. The Duke of Cumberland had given them battle at Hastembeck, and had been defeated. In order to save the electorate of Hanover from entire subjugation, he had made, at Closter Seven, an arrangement with the French generals, which left them at liberty to turn their arms against the Prussian dominions.
That nothing might be wanting to Frederic's distress, he lost his mother just at this time; and he appears to have felt the loss more than was to be expected from the hardness and severity of his character. In truth, his misfortunes had now cut to the quick. The mocker, the tyrant, the most rigorous, the most imperious, the most cynical of men, was very unhappy. His face was so haggard and his form so thin, that when on his return from Bohemia he passed through Leipsic, the people hardly knew him again. His sleep was broken; the tears, in spite of himself, often started into his eyes; and the grave began to present itself to his agitated mind as the best refuge from misery and dishonor. His resolution was fixed never to be taken alive, and never to make peace on condition of descending from his place among the powers of Europe. He saw nothing left for him except to die; and he deliberately chose his mode of death. He always carried about with him a sure and speedy poison in a small glass case; and to the few in whom he placed confidence he made no mystery of his resolution.
But we should very imperfectly describe the state of Frederic's mind, if we left out of view the laughable peculiarities which contrasted so singularly with the gravity, energy, and harshness of his character. It is difficult to say whether the tragic or the comic predominated in the strange scene which was then acting. In the midst of all the great King's calamities, his passion for writing indifferent poetry grew stronger and stronger. Enemies all round him, despair in his heart, pills of corrosive sublimate hidden in his clothes, he poured forth hundreds upon hundreds of lines, hateful to gods and men, the insipid dregs of Voltaire's Hippocrene, the faint echo of the lyre of Chaulieu. It is amusing to compare what he did during the last months of 1757 with what he wrote during the same time. It may be doubted whether any equal portion of the life of Hannibal, of Cæsar, or of Napoleon, will bear a comparison with that short period, the most brilliant in the history of Prussia and of Frederic. Yet at this very time the scanty leisure of the illustrious warrior was employed in producing odes and epistles, a little better than Cibber's, and a little worse than Hayley's. Here and there a manly sentiment which deserves to be in prose makes its appearance in company with Prometheus and Orpheus, Elysium and Acheron, the plaintive Philomel, the poppies of Morpheus, and all the other frippery which, like a robe tossed by a proud beauty to her waiting-woman, has long been contemptuously abandoned by genius to mediocrity. We hardly know any instance of the strength and weakness of human nature so striking, and so grotesque, as the character of this haughty, vigilant, resolute, sagacious blue-stocking, half Mithridates and half Trissotin, bearing up against a world in arms, with an ounce of poison in one pocket and a quire of bad verses in the other.
