In these hours of trouble the noble Wilhelmina was as true to her brother as the magnet to the pole. She was appalled by no dangers, and roused all her energies to aid that brother, struggling, with the world arrayed against him. The king appreciated his sister’s love. In a poetic epistle addressed to her, composed in these hours of adversity, he wrote:

“Oh sweet and dear hope of my remaining days! oh sister whose friendship, so fertile in resources, shares all my sorrows, and with a helpful arm assists me in the gulf! it is in vain that the destinies have overwhelmed me with disasters. If the crowd of kings have sworn my ruin, if the earth have opened to swallow me, you still love me, noble and affectionate sister. Loved by you, what is there of misfortune?”

In conclusion, he gives utterance to that gloomy creed of infidelity and atheism which he had adopted instead of the Christian faith. “Thus destiny with a deluge of torments fills the poisoned remnants of my days. The present is hideous to me, the future unknown. Do you say that I am the creature of a beneficent being? I see that all men are the sport of destiny. And if there do exist some gloomy and inexorable being who allows a despised herd of creatures to go on multiplying here, he values them as nothing. He looks down on our virtues, our misdeeds, on the horrors of war, and on all the cruel plagues which ravage earth, as a thing indifferent to him. Wherefore my sole refuge and only haven, loved sister, is in the arms of death.”[106]

Twenty years before this, Frederick, in a letter to his friend Baron Suhm, dated June 6, 1736, had expressed the belief that, while the majority of the world perished at death, a few very distinguished men might be immortal.

“The thought alone,” he wrote, “of your death, my dear Suhm, affords me an argument in proof of the immortality of the soul. For is it possible that the spirit which acts in you with so much clearness, brightness, and intelligence, which is so different from matter and from body—that fine soul endowed with so many solid virtues and agreeable qualities—is it possible that this should not be immortal? No! I would maintain in solid argument that, if the greatest part of the world were to be annihilated, you, Voltaire, Boileau, Newton, Wolfius, and some other geniuses of this order must be immortal.”[107]

Now, however, Frederick, in that downward path through which the rejecters of Christianity invariably descend, had reached the point at which he renounced all belief in the immortality of the soul and in the existence of God. In a poetic epistle addressed to Marshal Keith, he declares himself a materialist, and affirms his unwavering conviction that the soul, which he says is but the result of the bodily organization, perishes with that body. He declares suicide to be the only remedy for man in his hour of extremity.

Wilhelmina, in her distress in view of the peril of her brother, wrote to Voltaire, hoping that he might be persuaded to exert an influence in his favor.

“The king, my brother,” she wrote, “supports his misfortunes with a courage and a firmness worthy of him. I am in a frightful state, and will not survive the destruction of my house and family. That is the one consolation that remains to me. I can not write farther of it. My soul is so troubled that I know not what I am doing. To me there remains nothing but to follow his destiny if it is unfortunate. I have never piqued myself on being a philosopher, though I have made many efforts to become so. The small progress I made did teach me to despise grandeur and riches. But I could never find in philosophy any cure for the wounds of the heart, except that of getting done with our miseries by ceasing to live. The state I am in is worse than death. I see the greatest man of his age, my brother, my friend, reduced to the most frightful extremity. I see my whole family exposed to dangers and, perhaps, destruction. Would to Heaven I were alone loaded with all the miseries I have described to you.”

Five days after this letter was written to Voltaire by Wilhelmina from Baireuth, Frederick, on the 17th of September, 1757, wrote his sister from near Erfurt. This letter, somewhat abbreviated, was as follows:

“My dearest Sister,—I find no other consolation but in your precious letters. May Heaven[108] reward so much virtue and such heroic sentiments! Since I wrote you last my misfortunes have but gone on accumulating. It seems as though destiny would discharge all its wrath and fury upon the poor country which I had to rule over. I have advanced this way to fall upon a corps of the allied army, which has run off and intrenched itself among hills, whither to follow, still more to attack them, all rules of war forbid. The moment I retire toward Saxony this whole swarm will be upon my heels. Happen what may, I am determined, at all risks, to fall upon whatever corps of the enemy approaches me nearest. I shall even bless Heaven for its mercy if it grant me the favor to die sword in hand.

“Should this hope fail me, you will allow that it would be too hard to crawl at the feet of a company of traitors to whom successful crimes have given the advantage to prescribe the law to me. If I had followed my own inclinations I should have put an end to myself at once after that unfortunate battle which I lost. But I felt that this would be weakness, and that it behooved me to repair the evil which had happened. But no sooner had I hastened this way to face new enemies than Winterfield was beaten and killed near Gorlitz; than the French entered the heart of my states; than the Swedes blockaded Stettin. Now there is nothing effective left for me to do. There are too many enemies. Were I even to succeed in beating two armies, the third would crush me. As for you, my incomparable sister, I have not the heart to turn you from your resolves. We think alike, and I can not condemn in you the sentiments which I daily entertain. Life has been given us as a benefit. When it ceases to be such— I have nobody left in this world to attach me to it but you. My friends, the relations I loved most, are in the grave. In short, I have lost every thing. If you take the resolution which I have taken, we end together our misfortunes and our unhappiness.

“But it is time to end this long, dreary letter. I have had some leisure, and have used it to open to you a heart filled with admiration and gratitude toward you. Yes, my adorable sister, if Providence troubled itself about human affairs, you ought to be the happiest person in the universe. Your not being such confirms me in the sentiments expressed in my epistle.”
