This page is read live from our databases of Commanders and U-boat patrols. The data seen above may change slightly from time to time as new or updated information comes to light.
We consider extended time in enemy waters to be a patrol, especially later in the war when many boats were being lost only a few days out from their bases. The 43 day journey of the 20-year old Ludwig-Ferdinand von Friedeburg commanding the large U-155 from besieged Lorient, France on on 9 Sept 1944 to Flensburg, Germany certainly falls under that category.
The average age of the U-boat commanders
During the war the average age of commanders on patrol was about 28 years.
