Page 7 - 09.49 "To avoid surprises, gave the steamer a stern shot: Bow left, target angle 90°, depth 2 meters, Eto tube runner ejected with mine gear - Crash dive. Running time 127 seconds - 1900 meters. Hit center." (Eto = Electric torpedo)
Page 8 - 00.36 "Coup de grāce: Stern shot Eto depth 3 meters. Again a tube runner - ejected with the mine gear - running time 30 seconds = 625 meters. Hit center: Steamer sinks immediately."
TypeVIIb and Type VIIc - 1940/1941 - both have performed two stern shots with G7e/Eto |
The KTB must be falsified to confuse the enemy
Just kidding, Mittelwaechter! Great find and thanks for sharing!
My guess still is that probably it was considered unpractical in the beginning, but later it turned out to be practical (unpractical according to peace-time regulations, but in war-time possible).

PS: Just a side note: KTBs were in fact sometimes falsified to hide mistakes, e.g., Lemp was ordered to erase all entries concerning the sinking of Athenia from his KTB, see the book "U-Boat Attack Logs" by D. Morgan & B. Taylor.
