This his book tells one more key part of the big story and is one more piece in the giant puzzle of the history of World War II. Its value for historians cannot be underestimated. Throughout the stories of the attacks by German and Italian submarines on Allied shipping in the water around the Bahamas and the Turks and Caicos, several consistent themes emerge in Wibergs thorough accounts. Prime among them is the heroism of the merchant mariners who time and again put themselves in danger as they performed the critical task of moving supplies, military and civilian, which were vital to ultimate victory. We read of numerous instances of sailors having their ships shot out from under them and then continuously going back to sea and having additional ships torpedoed and sunk. We can also recognize what we know today as Post Traumatic Stress Disorder (PTSD), which was seldom recognized 75 years ago.
