I saw that movie "Battle of the Atlantic". One of the better documentarys out there imo. It actually inspired part of this idea. Where they explained when and how the Germans were able to crack the convoy codes etc. What realy stuck in my mind was the things said in the interviews by the merchants. Anyhow back to business. Took a screen of one of these messages in it's current format.
This one doesn't say "on" after the port of destination. If it did margin constraints would force it to show up just before the month day, year. In regular view a mouse over will indicate the in game day, but not in Radio Message screen. And so the argument for adding the date sent in the header for these series makes sence. :hmm:
