Yesterday, 19 Feb., 2015, I met an interesting fellow at the doctor's waiting room. He was Assistant Engineering Officer, later Engineering Officer, in the SEA ROBIN, an American desiel-electric submarine. Just before I met him he was relating how his boat and crew had spirited some covert operatives into North Korean held territory. Our time was brief. About the only information I pressed him for was concerning depth charge attacks. Yes, they were attacked but never closely.
