Ten Years and Twenty Days is a direct reference to the time Karl Doenitz spent in Spandau Jail having been convicted of War Crimes.
As an English boy growing up in a post-war Britain (I was born in 1950), we would play games where the Germans always lost - just like the Cowboys always won and the Indians always lost. Much later in life, I began to research various ships and shipwrecks through my scuba diving and the name of Karl Doenitz came up time and again. Over many years I came to respect this man for the way in which he conducted both himself and his branch of the war with Britain. I consider him to have been an honourable enemy of my country.
Having read so many accounts of this once great Admiral before reading his own memoirs, I have reached the conclusion that he was convicted of no more a crime than "being one of the enemy" and it was for that he served his ten years and twenty days. Others, of course, were directly responsible for the great human atrocities of WW2 and it was they who were either sentenced to death of life imprisonment.
I am sure there are those who will disagree with my assessment of this man - and, indeed, their own assessment may be more accurate. Nevertheless, this book is a great work and one which should be read by all those with an interest in Karl Doenitz the German Naval Officer and Karl Doenitz - the last Fuhrer who's first task on succeeding Hitler was to seek peace.
