La base sous-marine de La Rochelle - La Pallice

During the Second World War, La Pallice, commercial port of La Rochelle, was chosen by the German navy to become the home port of its submarines. In order to put these U-Boote away from the mission, a gigantic bunker will be built right in the middle of the harbor: the underwater base. How will it be built, by how long and by whom? How does it work, with its many workshops and services necessary for the life of the base? What are his defenses? What types of submarines will come to be repaired? What actions will be taken by the Allies to try to stop it from working? What are the tasks assigned to the shipyard workers working at the base during the 5th La Rochelle siege? What has become of her since the end of the conflict, especially for cinema? This is what you will discover in this book illustrated by 400 photos, documents and plans.
