You have to have a calm before the storm. If every episode was all action it would get old fast. Personally, I would have shot the Governor directly in the chest and hoped that my guys outside the building could handle the others when they heard the gunshot. I would not give up Michonne.
They have the advantage at the prison by a longshot. They're dealing with lots of people with no combat experience, and they have all those new weapons and ammo. Hopefully they took some of those grenades too. I would hide Darrel and Michonne in the woods to sneak up from behind the Governor's crew after the battle starts.
