This is a good book that centers around the sixth war patrol of U-564 under the command of Reinhard "Teddy" Suhren (this was also Suhren's last war patrol). The book gives good background on Suhren and the men serving under him on the boat, and then gives great detail about the whole patrol of U-564. A German propaganda journalist went with them on this specific patrol and the accompanying photographs are excellent. They and the book gives a very good glimpse on what life must have been like on a U-boat during a war patrol across the Atlantic and into the Caribbean. The book also tells of the hardships faced by the sailors on a daily basis and their camaraderie during these trying times. The epilogue also tells what happened to Suhren, his boat and certain individuals in his crew. A must for U-boat enthusiasts.
