We’ve just recently completed scanning my Marine grandfather’s letters home from Guam in ‘44 & ‘45. He was too old for the front, and spent his time either in the infirmary or the quartermasters’ corp. He wrote virtually every day, and I understand my grandmother did the same from the home front. Unfortunately, those letters did not survive.
I imagine the guys on the front line seeing all the action didn’t have a whole heck’uv a lot of time to write!
