I dont quite understand this . Your Grandfather was Gunter Lutjens younger brother , and your grandfather left Germany in the 1900s ? or is that a typing error ?
There were many Jewish and part Jewish officers in all the German services during the Kaisers war , the air ace Werner Voss comes immediately to my mind , but there were hundreds if not thousands more , Indeed many of these men would end up in the Nazi camps later , their commission document and medals in their suitcases , there are a number of witness accounts of such cases .
It is from catholic Austria that most of the anti-semitism seems to have initially sprung , certainly many of the Final Solution's leading active players were Austrians by origin , and the latterday Mr Georg Haider's appearance on the political scene in the "new" Austria in recent times had British ears pricked for the renewed stamp of jackboots for a while .
I also dont understand your reference to a choice between "Conscription into the Kriegsmarine or Death" as being the options offered to Gunter Lutjens .
Km officers were selected pre-war from volunteers , trained as cadets , then the standard route of midshipman , Leutnant , and so on up the long command tree .
I cant see anyone whose loyalties would even be suspected of being possibly divided , being given any high command position , still less major operational command at the outset of a war by a bunch of paranoid thugs like dear Adi and the rest of them . I cant see it , sorry .
