I attacked the AI's artillary(1 battery of 12 pounders line artill), destroying 2 of the guns with my Howitzers, the rest of the crew routed.
Later they came trotting back to re-man their guns, but they were in a different place manning four invisible guns, not 2(I could see the muzzle flashes).
They had'n't moved the original remaining 2 guns, never mind that the other 2 looked like kindling, and also you can't move the guns without the nags(horses).

Some sort of CA implanted super Gun battery or what?
