Now, I don't know the dates off by heart but is it possible that when your patrol started that the majority of the ships in the convoy you encountered started as Neutral but as time passed in your patrol they became Enemy? ...

Nope. that can't be it. A majority of the ships in the convoy were British. Most of the rest were Canadian. The convoy would have had to have left port more than 18 months earlier for the majority to have been neutral at time of embarcation.
