Sounds like a rewarding patrol, and from a strictly historical perspective- a huge, huge success that would have had the ComSubPac himself waiting for you at the docks ready to pass out a bag full of medals and invite you and your officers to join him for dinner to discuss your success!
I can certainly understand the thrill of contact, the chase and the hoped for results... and a single kill that happens to be a battleship is likely to still represent the pinnacle of most any sub commanders career- and make you a hero on a national scale in real life... I get it.
But from a purely "entertainment value" perspective... well, you know me. Like a spoiled brat!
