The Union had a very strong (~3000 power estimated) force entrenched 4 or 5 outside of Alexandria, so I knew I was gambling with the attack.
What surprised me was that the turn history says Jackson's corps engaged on day 8 but then retreated successfully in hour 2 of day 8 before the battle was joined, taking 20 hits. His corps changed to green posture and remained in Alexandria. So instead of combining with a 3:2 power advantage, Longstreet's corps attacked alone... with predictable results.


I am a new player so I can't really gauge whether this is an odd result, but it surprised me because I thought red/red is a "no retreat" mode and Jackson is one of the best leaders in the game. I was surprised that his corps retreated in hour 2 after having a red/red assault posture but then remained in the region.
1. Why did Jackson retreat in hour 2 with a red/red posture?
2. Why did the engagement start on Day 8 after a 3-day march?
3. Why did Jackson stay in the region after retreating but Longstreet went back to Manassas?
Is it worth asking my PBEM opponent to post the turn files here for a post mortem or can a more experienced player let me know whether this is a common result? Any thoughts?
