"Whether or not he quit without informing us, the government must not leave him to fend for himself ... I don't know what they (the authorities) are doing. They don't tell me anything."

Alexandrov was captured on May 16 and has been charged by the Ukrainian authorities with terrorism. The soldiers have denied the charge, and say they did not kill anyone.
Alexandrov, 28, says he believes the Russian authorities pressured his wife Yekaterina, who serves in the human resources department of the same military unit, to tell Russian state television that he had quit before fighting in east Ukraine
Увы! утешится жена,
И друга лучший друг забудет;
Но где-то есть душа одна -
Она до гроба помнить будет...
