I had a number of Great Uncle’s on paternal side (father) who were in The Great War (WW 1). Two died as a result. Two were in several major conflict battles and lived with the horror of war the rest of their lives. A couple more were in Army but stayed state side since the war ended before they were sent.
What is interesting is that all of them were first generation born german-american. The irony of it all. Their parents left 50 yrs or so before. In memory of Great-Uncles, Theodor Rettammel and Henry Wendland.
