Welcome, I love Dublin and France.
A few free tips:
1) Don't be too concerned about VP hexes. Destroy the enemy and take the VP hexes if needed.
2) Manage your unit integrity. Meaning, avoid being detached.
3) Watch your artillery ammo. Some scenarios will cause you to come up short if you blast away at every opportunity. You can set you AI fire to Min/Med/Max. If ammo is plentiful, fire at max.
-One example of artillery ammo being short, the historical Chickamauga scenario.
Bonne Chance!4) Flank Flank Flank- Enough Said on that.
5) Be sure you understand the chosen optional rules. I played a recent game and didn't realize that the alternative release rule had been chosen. That really screwed me up. The enemy was gone when I charged.
Merde!6) Be sure to discuss what house rules you will play with or there could be a misunderstanding later.
7) Be careful when using speed move options. You can bump into the enemy when it could have been avoided.

Keep your artillery on a tight leash and well protected.
These are just a few items. The list could go on and on!
