Wall

In the game's words

How to use it

Walls are a defensive building placed in a ring or arc to enclose and protect units, or placed across a narrow gap to restrict enemy movement through an area. They are relatively cheap to build and effective at keeping out early attacks, but when artillery show up, walls become significantly less of an obstacle. The lesson: if you want walls, try to build them early. If you see your enemy has extensive walls, artillery are a good means to destroy them.

History

Early fortifications in the New World were palisades constructed of the sharpened trunks of trees, which were driven into the ground side by side to form walls. Some of these palisade walls, especially when a little green, were remarkably effective at withstanding bombardment by artillery because they could flex as they were hit instead of splintering like properly dried wood or shattering like masonry walls. More effective than either wood or stone at withstanding bombardment were the bermed earthworks famously ringing star forts like Fort McHenry. A fort in the era of cannon was a series of sculpted plains, ditches, bastions, and walls of earth and stone that maximized line of sight and fire for defenders.
