Well %&@&!! I decided to sink one more convoy before returning to port to rearm to proceed with my plan to achieve a medal of honor. I didn't know at the time that the sinking of this final convoy would break the threshold for the medal of honor. I skipped through the award screen as if it were another news report. Worst part is I saved right after.
I had to look at the game files to see what the congratulations letter would say, and I spotted a typo.
Here's a picture of my current status. I'll have to earn another one of these to show you the letter (and typo).
