Terrain vs defense

[TheGrayMouser]

Quick question, couldn't quite get an answer from the manual

Enclosures negate the effects of cavalry POA's AND being charged in the flank or rear for infantry defenders, however in a recent game I swear my all musket unit of medium infantry suffered a flank hit from an enemy cavalry unit. I believe I lost the benefit of the enclosure as I had changed facing and or moved my turn before the cavalry attack. This is correct, no?

No, not correct.

Three possibilities reasons for the events spring to mind.

1) Enclosures do not protect against flank attack, hedges do. So a unit is not protected against enemy attacking from the same enclosed field.
2) The unit looked as it it was defending a hedge but in fact wasn't. When the hedges are along a road, you have to be on the road tile to get protection. Troops in an adjacent field do not get protection from the road hedges. (The hedge is not on the edge of the field tile.)
3) The unit was attacking another unit across the hedge. If a unit is attacking another unit across the hedge, it loses the protection of the hedge, even against other units that attack it.

Thanks RBS, I think my confusion stemmed from the programs skirmish battle, which often lays enclosure tiles that all four sides are enclosed by some sort of shrubberies, but sometimes has multi tiled ones where some inner tiles "edges" do not. Also tree lined roads occasionally make up one of the "edges" ( I think this is what I witnessed, my infantry although "in" an enclosure, had its flank to a tree lined road which is where the attack came from)
