A wall gives the defending unit a strong front, but the troops fix their attention on that protection. British units move around their left without drawing a response. The position then fails because its flank is open, despite the cover facing forward. The game sequence offers a compact lesson in all-round awareness: a strong obstacle protects only the direction it faces.

A strong wall cannot protect an open flank
A unit gains cover behind a wall, then loses the position because it ignores British troops moving around its left.
