The Empress was so angry with Apraxin that she removed him from command, and launched an investigation into his actions. She tried Alexey Bestuzhev-Ryumin, her chancellor and a friend of Apraxin, for treason. Bestuzhev-Ryumin was later exiled to his estates. Elizabeth appointed William Fermor as the new Russian commander and the next year the invasion started again. Fermor had an entirely different attitude towards supplying his troops, and developed an extensive network of local supply depots and sources outside of the Russian boundary. This, though, attracted aspersions from his political enemies in St. Petersburg, who claimed he was wasting the imperial treasury; however, Fermor was considerably more successful in 1758 than his predecessor had been in 1757.
