 Tamarov, only sixteen at the beginning of the series, was initially somewhat childish, but rapidly matured into an experienced and trustworthy officer.He was "Hibernia's" first midshipman from Holser's promotion to Lieutenant until the arrival of Philip Tyre, and following his own promotion to Lieutenant was put in charge of the wardroom to deal with Tyre.After "Hibernia's" return, Tamarov became second lieutenant of "Portia", and during her voyage finally came to terms with the fact that his hatred of Tyre was spiralling out of control, and ended his vindictive hounding of the midshipman.
