Peter lived at this time with his young wife at a certain country palace belonging to him, situated on the banks of a small river a few miles from Moscow. The name of this country-seat was Obrogensko. Such was the state of things at Moscow when Prince Galitzin returned from his campaigns in the Crimea. The prince found that the power of Sophia and her party was rapidly waning, and that Sophia herself was in a state of great anxiety and excitement in respect to the future. The princess gave Galitzin a very splendid reception, and publicly rewarded him for his pretended success in the war by bestowing upon him great and extraordinary honors. Still many people were very suspicious of the truth of the accounts which were circulated. The partisans of Peter called for proofs that the victories had really been won. Prince Galitzin brought with him to the capital a considerable force of Cossacks, with Mazeppa at their head. The Cossacks had never before been allowed to come into Moscow; but now, Sophia having formed a desperate plan to save herself from the dangers that surrounded her, and knowing that these men would unscrupulously execute any commands that were given to them by their leaders, directed Galitzin to bring them within the walls, under pretense to do honor to Mazeppa for the important services which he had rendered during the war. But this measure was very unpopular with the people, and, although the Cossacks were actually brought within the walls, they were subjected to such restrictions there that, after all, Sophia could not employ them for the purpose of executing her plot, but was obliged to rely on the regular Muscovite troops of the imperial Guard. The plot which she formed was nothing else than the assassination of Peter. She saw no other way by which she could save herself from the dangers which surrounded her, and make sure of retaining her power. Her brother, the Czar John, was growing weaker and more insignificant every day; while Peter and his party, who looked upon her, she knew, with very unfriendly feelings, were growing stronger and stronger. If Peter continued to live, her speedy downfall, she was convinced, was sure. She accordingly determined that Peter should die. The commander-in-chief of the Guards at this time was a man named Theodore Thekelavitaw. He had been raised to this exalted post by Sophia herself on the death of Couvansky. She had selected him for this office with special reference to his subserviency to her interests. She determined now, accordingly, to confide to him the execution of her scheme for the assassination of Peter.
