I had an interesting idea for a battle tactic in medieval warfare. Imagine sending your armies against your enemies in waves. The first few waves would consist of light infantry and cavalry, which have inferior armor and weapons than heavy infantry and cavalry. These first waves would be used to test your enemy’s defenses as well as wear them down with each wave. Meanwhile, you keep your heavy infantry and cavalry in reserve until your enemy is too weak and tired to fight back. When your light infantry and cavalry are spent and your foe’s defenses are exhausted, then you send in the rest of your forces to wipe out the survivors. I am thinking of including a tactic such as this in my new fantasy book in a number of battles.
