From the paternal side, my grandfather and his brother (my great-uncle)were on submarines in the Pacific theatre. My great-uncle Vernon was on the USS Batfish, the most decorated US sub of the war. There is a book written about it, I'm not sure of the author, but there are many pictures from the sub with my great-uncle in them. He died when I was young but from the book I guess the Batfish actually shelled the Japanese mainland and then had to run for her life through minefields and a vicious Destroyer screen. I don't remember what sub he was on but my grandfather has told me his sub survived one of the most intense depth-chargings documented. Good thing they survived or I would not be here. Most stories I have from my dad are from Vietnam. Himself and two of his brothers were over there and all made it back safe.
