"Da Sophie Dorothea bis zu ihrem Tod behauptete, sie sei ihrem Mann nicht untreu gewesen (als Äußerstes gab sie lange nach der Scheidung zu, sie habe ihn vielleicht 'gekränkt'), und ihr Kammerfräulein Eleonore von dem Knesebeck bezeugte, zwischen ihrer Herrin und Königsmarck habe es nur 'amitié et conversation familiale' gegeben ..." (in: Ragnhild Hatton: Georg I. - Ein deutscher Kurfürst auf Englands Thron, ebenda, S. 56). Sind die angeblich gefundenen Briefe von ihr und Königsmarck wirklich echt? Dass Sophie Dorothea und Königsmarck ihre Briefe, die solch delikanten Inhaltes gewesen sein sollen, zur sicheren Verwahrung an Philipps Schwester Aurora geschickt hätten, klingt dermaßen unglaubwürdig. Solche Briefe wären sofort verbrannt worden. Dass dann jedoch nach dem Tod von Aurora diese verhängnisvollen Briefe auch noch an deren Schwester Amalia Wilhelmine weitergereicht worden seien, wo sie sich bei deren Nachkommen bis zum 19. Jahrhundert befunden hätten, ohne dass irgendjemand aus dieser Familie mit ihnen Profit hätte machen wollen, halte ich persönlich für völlig unsinnig. Übrigens hatte Sophie Dorothea die Scheidung bzw. Trennung gewünscht. Sie verweigerte nach der Ermordung von Königsmarck das Zusammenleben mit ihrem Gatten und die Wiederaufnahme der ehelichen Beziehung. Ihre Ehe wurde am 28. Dezember 1694 aufgelöst. Sophie Dorothea wurde als dem schuldigen Teil die Wiederverheiratung untersagt, Georg hingegen wurde sie ausdrücklich gestattet. Im Jahr 1725 bestand eine Chance, dass Sophie Dorothea mit Hilfe ihrer gleichnamigen Tochter ihrer Gefangenschaft endlich entgehen konnte. Aber sie wollte "keine Begnadigung, sondern eine Aufhebung des Urteils von 1694. Auf diese Weise sollte deutlich werden, daß sie ungerecht behandelt worden war. Ein Ausgleich für das von ihr erlittene Unrecht sei um ihrer gloire willen unerläßlich, schrieb sie an ihre Tochter." (in: Ragnhild Hatton: Georg I. - Ein deutscher Kurfürst auf Englands Thron, ebenda, S. 64).
Brief von Sophie Dorothea, geschrieben am 26. September 1694 in Lauenau: "By the grace of God, Sophia Dorothea, &c. Since our illustrious husband, George Lewis, Crown Prince of Hanover, has caused to be delivered to the matrimonial court in Hanover constituted to try this case by our father and father-in-law, a complaint of desertion against us, and has requested a complete separation of marriage between our husband and us, as we have learned from this complaint, and a communication from the court that made it known to us; and since our lord and father has sent to us his president and grand marshal of the court, von Bulow, at this place, that we might make known what we thought best, according to our comprehension respecting such complaint of desertion, and that we should instruct for that purpose the counsellor of the court, Rudolph Thies, in order to convey our declaration to the said matrimonial court for its information, leaving the circumstances mentioned by the attorney of our lord and husband undisturbed. We declare, for the rest, as we well understand our intention, and in accordance with the contents of the aforesaid complaint, have well and freely considered it, that we still adhere to our oft-repeated resolution never to cohabit matrimonially with our husband, and that we desire nothing so much as that separation of marriage requested by our husband may take place. And thereupon we herewith empower and command our solicitor, the counsellor of the court Thies, to present this our declaration in answer to the letter of the 20th of September, 1694, sent to us by the aforesaid court. In witness whereof we have signed this with our hand, and fixed to it our seal." (in: Robert Folkestone Williams: Memoirs of Sophia Dorothea, Consort of George I, Vol. 1, London 1845, pp. 258-259).
"It has even been stated that he [ihr ehemaliger Gatte Georg Ludwig von Braunschweig-Lüneburg, König von Großbritannien und Kurfürst von Hannover] made proposals for a reconciliation to his unhappy captive [Sophie Dorothea], and that she returned the spirited answer - 'If what I am accused of be true, I am unworthy of his bed; and if the accusation be false, he is unworthy of me. I will not accept his offer.' This reply, however, seems to belong to a much earlier period of her imprisonment, when a proposal was made for her return to her husband, unaccompanied with such an acknowledgment of the wrongs she had endured, and of such security for her honour and happiness, as would have justified a virtuous woman accepting it." (in: Robert Folkestone Williams: Memoirs of Sophia Dorothea, Consort of George I, Vol. 1, London 1845, pp. 381-382).
Aussage ihrer Hofdame, Eleonore von dem Knesebeck: "Perfectly innocent as was the Princess in the friendship which from infancy she had cherished for Count Königsmark, so blameable was she for her behaviour, when she heard of the deplorable death of the Count, who was destined to lose his life for her sake. It was impossible for her, in the first moment, to conceal the pain she felt; she complained bitterly, and several times wished that, now Königsmark had died on her account, she could die too; and, as I have said, she thereby excited suspicion that she had been on terms of more than ordinary friendship with the deceased Count. ... She [Sophie Dorothea] was then taken to Ahlden, which place was to serve for her residence, and was there examined on different points, and in particular asked whether she had not kept up an illicit connexion with Königsmark, whether she was not pregnant by him [eine Behauptung von Clara Elisabeth von Meysenbug, der Gräfin von Platen und Hauptmätresse ihres Schwiegervaters, die in der Tat in ihrem Verhältnis mit Königsmarck schwanger geworden war], and whether she had not projected the flight to Wolfenbüttel in defiance of the whole electoral house. Freely and frankly as she confessed the last, alleging that the cruelty of the Electoral Prince had forced her to that resolution, so firmly did she reply to the other points, and desired, in attestation of her innocence, to have the holy sacrament administered to her upon it. Countess Platen, fearing that the innocence of the Princess might thereby be brought to light, strove to prevent it by all possible means; but the desire of Duke George William [dem Vater von Sophie Dorothea] prevailed ..."
