After being held prisoner at Narva and
Reval, Alexander was taken to
Stockholm in May 1701. The Swedes regarded him as the highest-ranking of the aristocratic
prisoners of war. He was confined at the home of Chief Inspector Stierndahl, but later apparently moved to the Treasurer's House (Räntmästarhuset) at
Skeppsbron. Alexander enjoyed more freedom than other Russian prisoners and was on good terms with many at the
Royal Council and
court. Among these was
Johan Gabriel Sparwenfeld, who had been close to Alexander and his father during his stay in Moscow. Sparwenfeld helped Alexander to have the Georgian fonts cast in Stockholm and send home to Moscow. The conditions were tightened in 1705. When the Swedes discovered that the prince had been in secret correspondence discussing escape plans with the fellow internee Prince Iakov Dolgorukov, Alexander was banished to a castle at
Linköping. As his health deteriorated, the prince was transferred from the castle to a house in the town and, in April 1706, returned to Stockholm. In 1708, the prince and other Russian detainees were discovered to possess drawings of Swedish fortifications, and on Charles XII's order, their rights, including that of correspondence, were again restricted. Alexander, however, continued to enjoy certain favor with the
dowager queen and
Princess Ulrika Eleneora and was allowed, to the displeasure of the Defense Commission, to visit the court. In his quest to secure Alexander's release, the ex-king Archil tried to approach the
Habsburg court for mediation.
Prince von Kaunitz, the
Imperial Chancellor, instructed the Habsburg ambassador at Stockholm to intercede at the Swedish court, but nothing came of this. Archil then, in February 1706, personally appealed to Charles XII, imploring him to exchange Alexander for a number of Swedish prisoners-of-war. According to one account, the Swedes countered with demands for the release of 60 of their officers in a prisoner swap. Tsar Peter inquired if Alexander himself was ready to accept such a precondition and the prince rejected the offer. == Release and death ==
