On February 25, Count Mercy was present at a banquet given by Chancellor Vorontsov for the emperor and for all foreign ambassadors; three hundred people were in the hall. Mercy found Peter uneasy. At nine o’clock the company sat down. During the meal, which lasted four hours, Peter drank Burgundy, became excited, and, at the top of his voice, proposed a toast to the king of Prussia. At two in the morning, the diners rose from the table, baskets of clay pipes and tobacco were brought, and the men began to smoke. Peter, pacing up and down the room, pipe in hand, confronted the new French ambassador, Baron de Breteuil: “We must make peace,” he said. “For my part, I have declared it.”
“And we, too, sire, would have it,” the ambassador replied, then added, “honorably, and in agreement with our allies.”
Peter’s face darkened. “Just as you please,” he said. “For my part, I have declared it. You can do as you please. I am a soldier and I don’t joke.”
“Sire,” said Breteuil, “I will report to my king the declaration Your Majesty has been pleased to make to me.”
Peter turned and walked away. The following day, the ambassadors of Russia’s allies, Austria and France, were handed an official document which declared that the war had been going on for six years to the detriment of all. Now, the new Russian emperor, anxious to terminate so great an evil, had decided to announce to all the courts in alliance with Russia that in order to restore the blessings of peace to his own empire and to Europe, he was ready to sacrifice all the conquests made by Russian arms. He believed that the allied courts would also prefer restoration of general tranquillity and would agree with him. After reading the declaration, Count Mercy declared to Chancellor Vorontsov that he found the declaration obscure and impertinent. Writing to his own court in Vienna, he described it as venomous; as an effort to avoid the most solemn treaty obligations; and as an excuse to save the king of Prussia from impending destruction.
For Mercy and Austria, worse was to come. Peter’s declaration of peace turned out to be a preliminary to the signing of a formal alliance between Russia and Prussia. On March 3, the new Prussian envoy, young Baron von Goltz, arrived in St. Petersburg, where Peter received him enthusiastically. Goltz scarcely had time to congratulate the new monarch on his accession when Peter overwhelmed him with ardent assurances of his own admiration for the king of Prussia. He had a great deal to talk to him about in private, he whispered. Immediately after the audience, Peter thrust his arm through that of this new friend and carried him off to dinner, talking incessantly about the Prussian army and amazing Goltz with his intimate knowledge of the subject, including the names of almost every senior officer of every Prussian regiment. Goltz was provided with a mansion in which Peter visited him twice a day. Within a week, Goltz had completely eclipsed Keith, his English colleague, and, henceforth, until the end of Peter’s reign, Prussian influence dominated at the Russian court.
Goltz’s mission was to speed the end of the war and the detachment of Russia from her allies. To achieve this, he told Peter that Frederick was willing to consent to the permanent cession of East Prussia. Peter did not require this. On the contrary, he was willing to sacrifice everything to please Frederick. He let Frederick set the terms. When the king sent to St. Petersburg a draft treaty for an eternal peace between Prussia and Russia, it did not go through the normal channel; it was not submitted, or even shown, to Chancellor Vorontsov. Instead, Goltz simply read the text to Peter in private without witnesses, and on April 24, Peter signed it without comment, sending it to Vorontsov for confirmation. By this stroke of a pen on a secret treaty, the new emperor not only restored to Prussia all the territory won from her by Russia during five years of war but contracted an “eternal” alliance with Prussia.
Six days after the signing, the emperor celebrated the peace treaty with a banquet at which every guest was seated according to rank, the first time this precedence had been observed during his reign. Peter and his chancellor, Vorontsov, both wore the Prussian Order of the Black Eagle. The banquet lasted for four hours and four toasts were drunk: an expression of joy at the restoration of peace with Prussia; personal congratulations to Frederick II; a toast to perpetual peace between the two powers; and a toast to the “honor of all the valiant officers and soldiers of the Prussian army.” Each toast was accompanied by a triple salvo from the guns of the fortress of Peter and Paul, as well as from fifty cannon planted in the square outside the palace. There was no mention of the achievements, bravery, or losses of the Russian army, and, said Count Mercy, “nothing was omitted in the way of indecency and offensiveness in regard to his ancient ally, Austria.”
