U-boat Kriegstagebücher (KTB)

        This project is a collaborative effort.  The records were made available by others and the work to translate and prepare them for presentation on the web was performed by a very talented team.  The administrator is deeply grateful to the following individuals who have contributed their time and expertise to this project.
        The original set of KTBs were made available by German U-boat historians Rainer Busch and Roland Berr.  Rainer is the author of German U-Boat Commanders of World War II.  Wojciech Laskowski has helped this website by sharing KTBs.  His collection is available to the public via his Google Drive
        Translation of the initial KTBs was done by Uboat.net crew member Ranier Kolbicz of Switzerland with editing and assistance by United States U-boat researcher Ken Dunn.  Other contributors include Christine Hillmann of Brazil, retired Fregattenkapitän Jürgen Meyer-Brenkhof, Jan Kockrow and Andi Forster from Germany, Harald Jazdziewski, a native German who now lives in the United States and Robert Derencin from Croatia.
