At 3 am on 25 April, the three Romanovs, their retinue, and the escort of Yakovlev's detachment, left Tobolsk in a convoy of nineteen tarantasses (four-wheeled carriages), as the river was still partly frozen which prevented the use of the ferry.Service 2018, p. 167 After an arduous journey which included two overnight stops, fording rivers, frequent changes of horses and a foiled plot by the Yekaterinburg Red Guards to abduct and kill the prisoners, the party arrived at Tyumen and boarded a requisitioned train. Yakovlev was able to communicate securely with Moscow by means of a Hughes' teleprinter and obtained agreement to change their destination to Omsk, where it was thought that the leadership were less likely to harm the Romanovs.Service 2018, pp. 170–174 Leaving Tyumen early on 28 April, the train left towards Yekaterinburg, but quickly changed direction towards Omsk. This led the Yekaterinburg leaders to believe that Yakovlev was a traitor who was trying to take Nicholas to exile by way of Vladivostok; telegraph messages were sent, two thousand armed men were mobilized and a train was dispatched to arrest Yakovlev and the Romanovs. The Romanovs' train was halted at Omsk station and after a frantic exchange of cables with Moscow, it was agreed that they should go to Yekaterinburg in return for a guarantee of safety for the royal family; they finally arrived there on the morning of 30 April.Service 2018, pp. 179–182
