Go In and Sink
by Reeman, Douglas
As the balance of the war slowly shifts in Britain’s favour, Lieutenant Commander Steven Marshall brings his battle-scarred submarine into home port. Captain and crew are exhausted after 14 months’ continuous active service, but for most there can be no thought of leave. Marshall must return to the Mediterranean, but this time to a very different kind of war. For his new command is secret and extremely hazardous–a captured German U-boat. First published in 1973.
