Format of B.d.U'S War Log

        At the beginning of the War, B.d.U. kept his War Diary in the same type log book used aboard U-boats. The log was in chronological format.  Most entries consist of a time and an event. The column reserved for weather was left blank. Occasionally the days entry would start with a summary of the operational situation. Dönitz would occasionally make entries covering his thoughts on the development of the U-boat Arm, the employment of U-boats and other issues between his and higher headquarters.

       A sample of the KTB from the first month of the war is shown below.

 


 

The format shown below was adopted for the KTB in November 1941 and would remain in use for the rest of WWII.
