A good companion to this book,
Rezension bezieht sich auf: Cruel Sea, The (Permanent S.) (Taschenbuch)Written by someone who experienced WWII in convoy escort duty, The Cruel Sea is quite realistic in a double sense: You get the drama of the war as well as the times when war is dull or frustrating, for example when an officer dumps paperwork onto subordinates. Realistic without being cynical is a good combination.
And if you'd like to read another book on this theme but with more of the immediacy of the war, try C. S. Forester's, The Good Shepherd, the classic account of a single convoy at the height of the war with U-boats as told by the captain of a US destroyer. Unfortunately, new it seems to be available only in an overpriced but ugly reprint, so you might want to find a used copy. I have a paperback version that I reread every few years.
