Επιστολή του William Meyer (Kew, Surry, 4 Δεκέμβρη 1807) προς τον G. Hammond στο Υπουργείο των Εξωτερικών, με την οποία τον ενημερώνει για τις σχέσεις που πλέον έχουν διαμορφωθεί μεταξύ Ρωσίας και Βρετανίας, μετά την επικύρωση της Συνθήκης του Τιλσίτ, και του επισυνάπτει έκθεση με τις απόψεις του για το ζήτημα, απόψεις που πρεσβεύει και ο Φορέστης. Αυτό που στην ουσία υποστηρίζει ο Meyer είναι πως ο Ναπολέοντας προσπάθησε να αυξήσει την επιρροή του στην ρωσική αυλή, μέσω του «γαλλικού κόμματος» που υποστηρίζεται δεόντως από τους Έλληνες της Ρωσίας, οι οποίοι πάντα αναζητούν ευκαιρία για να αναβιώσουν το ταπεινωμένο τους κράτος. Έτσι ο Ναπολέοντας μοιάζει να έχει ωθήσει την Ρωσία σε μία πολιτική, που οδηγεί σε διάρρηξη των σχέσεων με την Βρετανία και έτσι στην απώλεια – για την Βρετανία – της ισχυρής ρωσικής δύναμης στην ευρωπαϊκή ήπειρο, την κύρια δύναμη μίας πιθανής νέας συμμαχίας εναντίον του. Και τονίζει πως επικεφαλής αυτής της γαλλικής επιρροής/κόμματος στην ρωσική αυλή είναι ο Αρχιδούκας Κωνσταντίνος.

The real motive and policy of Russia in declaring against Great Britain
The declaration of Russia against Great Britain has been super induced by one principal object, viz. to preserve the throne and existing government of Russia from bloodshed and anarchy.
The irretrievable step was taken.
The Treaty of Tilsit was ratified!
But how pacify the resentment of the Russian army, the only controlling power of that estate and haughty nation, stung with fury and revenge by the dishonorable and disgraceful the unnecessary and abrupt evacuation and abandonment of countries and places long endeared to their troops by habit, connections and property?
How regain the glory and rewards they were pursuing, when so irrecoverably and pusillanimously sacrificed to the throne of their rancorous enemy?
The ministers of Russia, victims of disappointed ambition, had unconsciously prepared for their sovereign the bloody state of his predecessor. To avert it, they sought in the first instance to make Great Britain a partner in their own weakness and dishonor; seeking thus to prove all parties, indiscriminately, the victims of the same misfortunes and of the same necessity.
The proffered mediation was necessarily rejected.
The discontents of the army, finding thus all their disgrace and disappointments unredeemed, were augmented and inflamed by this act of British constancy and political wisdom, which they had willingly possessed.
Bonaparte, now perceiving his insidious overtures rejected, and his warfare against Great Britain become useless, nay destruction to himself without the cooperation of a continental league, thus proving perhaps the inability of England to fight, singlehanded against France, instantly resorted to measures to provoke that cooperation. Aware of the discontent in the Russian army, he sought to work, on that basis, a revolution in the Russian government.
The number and influence of the French party in St. Petersburg is well known. They are supported by the Greek Russians, who always avail themselves of any prospect of producing a change in their own degraded state. The Archduke Constantine is at the head of the Greek party, now the tool of the French party. He is well affected towards the French. This prince fought at the battle of Austerlitz, and only from the emulation of personal military process, so common in the Russian army, but not from patriot zeal. He has often shown his impatience of his brother reign. More popular than him in Russia, from his daring spirit, from his intimate connection with the Greeks, by whom he was nursed and educated, from his relentless hatred of the Turks, and from his impatience to avenge the faded honors of the Russian arms, he had an easy task to gratify that ambition, which his own inclination and the seductive project of others fostered. Poignards were again drawn in the Russian court; the blows were arrived; but averted from their menaced victims by a timely acquiescence in the assassins will! Constantine! Still hopes to reign on that throne, consecrated to him at his baptismal rites!
The Russian cabinet aware of its awful situation, of the perils that menaced the Empire, of the inutility of farther reservation, took at once the only measure of preserving or prolonging its existence. It has openly ascribed to Great Britain, to her bad faith, the causes of all her misfortunes; and demands her redress and redemption of them. Thus she seeks to exonerate her councils and her military deeds from the imputation of imbecility perfidy and dishonor; thus she seeks to pacify a blind infuriate army; thus she provides an aliment for its rapacity and a justification for it. To save herself, she is constrained to accuse falsely a calumniated nation; to crush a defenseless one! She is forced to assume the mask of truth, honor and humanity, to conceal her own cowardice infancy and falsehood!
This is the result of French intrigues, of the counsels of faithless Greek agents, of Russian imbecility and of Russian treason, of a pusillanimous cabinet; it is the result of everything but of the spontaneous noble sentiments of Alexander, just and good, but circumvented!
He still occupies a throne an Autocrator Enchained.
