Well I finally got around to discussing with my grandmother (the one I visited this last weekend after I attended critter's funeral) her memories of the First World War. She doesn't remember much from that time, as she was only a little girl (she had just turned 8 when the Armistice was signed), but there were two memories that have stuck with her:
1.) Her father had a hired man named Sven (she thinks) helping around the farm during the spring & summer, who went and joined the army. My grandmother remembered thinking at the time that she would never see him again, because soldiers always died. (Such was the reasoning of a young girl in early-20th-century rural Minnestoa.) So she was very surprised when he returned less than two years later, apparently hale and unharmed.
2.) My grandmother was at school when news of the Armistice came in. This memory was somewhat more vivid for her because her mother burst into the schoolhouse (which you *never* did -- you always knocked first!) announcing it had been signed. Her parents had just returned from visiting the town (the family lived on a farm several miles northeast of Spring Grove) where news of the Armistice had only just arrived.
Apparently, church bells began ringing all over the countryside soon after, and went on for some time. My grandmother said you could even hear the bells (albeit faintly) from town. She doesn't remember if their family specifically celebrated or anything, but she does vaguely recall everyone being in a rather festive spirit the rest of that day.
That's pretty much it, at least in regards to memories specifically related to the war. My grandmother has talked quite a bit about her early life (including and especially her childhood) in general, though, and I've long found her to be a font of fascinating historical tidbits. Her stories really help give one a sense of what life was like back then.
Even better, her mind -- for all that she complains it isn't nearly what it used to be -- is an intelligent, organized, and highly-perceptive one, and subsequently she does a marvelous job of relating these stories in a way younger generations (including myself) can both understand and appreciate. I consider myself very lucky to still have her around!
