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.
When Sophia proposed her plan to Prince Galitzin, he was at first strongly opposed to it, on account of the desperate danger which would attend such an undertaking. But she urged upon him so earnestly the necessity of the case, representing to him that unless some very decisive measures were adopted, not only would she herself soon be deposed from power, but that he and all his family and friends would be involved in the same common ruin, he at length reluctantly consented.
The plan was at last fully matured. Thekelavitaw, the commander of the Guards, selected six hundred men to go with him to Obrogensko. They were to go in the night, the plan being to seize Peter in his bed. When the appointed night arrived, the commander marshaled his men and gave them their instructions, and the whole body set out upon their march to Obrogensko with every prospect of successfully accomplishing the undertaking.
But the whole plan was defeated in a very remarkable manner. While the commander was giving his instructions to the men, two of the soldiers, shocked with the idea of being made the instruments of such a crime, stole away unobserved in the darkness, and ran with all possible speed to Obrogensko to warn Peter of his danger. Peter leaped from his bed in consternation, and immediately sent to the apartments where his uncles, the brothers of his mother, were lodging, to summon them to come to him. When they came, a hurried consultation was held. There was some doubt in the minds of Peter's uncles whether the story which the soldiers told was to be believed. They thought it could not possibly be true that so atrocious a crime could be contemplated by Sophia. Accordingly, before taking any measures for sending Peter and his family away, they determined to send messengers toward the city to ascertain whether any detachment of Guards was really coming toward Obrogensko.
