How castle engineering multiplies defensive power

Castle engineering lets a small garrison defend against a much larger attacking force.

Notes

A castle turns available resources into a defensible structure through engineering and architecture. Its military advantage comes from allowing a small garrison to resist a much larger attacking force. The imbalance between defenders and attackers explains the value of castle construction. Fortification turns construction into a practical form of force multiplication.
