Torpedo Run by Douglas Reeman

It was in 1943. On the Black Sea, the Russians were fighting a desperate battle to regain control. But the Russians' one real weakness was on the water: whatever they did, the Germans did it better, and the daring hit-and-run tactics of the E-boats plagued them. At last the British agreed to send them a small flotilla of motor torpedo boats under the command of John Devane. Devane had been in the Navy since the outbreak of war. More than a veteran, he was a survivor - and the two rarely went together in the savage war of MTBs. Given command t short notice, Devane soon learned that, even against the vast and raging background of the Eastern Front, war could still be a personal duel between individuals.
