The Governor didn't strike you as someone who would expect you to hold your post until he gave you leave?
If the Command gave the order to "cut and run", it wouldn't've been termed "Abandonment". I can certainly see abandoning your post when all is lost, I don't see the Governor as that forgiving, though, if a "Cut and Run" order wasn't given..
One Day I hope to be the Man my Cat thinks I am
Where are we going? And why are we in this Handbasket?
