My wife's grandfather was in Lutheran seminary in Texas during WWII. He actually spent a night in jail for suspicion of being a spy as he spoke in German when visiting door to door. He was sent to German POW camps to conduct Lutheran services, and apparently used the German Bible. He also had this Lutheran Service Hymnal, I'm guessing he visited US bases in his part of Texas to conduct services for them too. I found these when cleaning out their house after his wife died and thought they were pretty interesting. The Bible is dated 1892, the service book isn't dated but one page has an introduction letter dated 2/1/44. Just thought I would share these. Any idea how common this kind of stuff is?
