Oh, and if you become a horse archer nut like me, you might find yourself low on ammo for a long battle (they have weaker missile attack than foot archers, less ammo 25 vs. 30, and 2/3 of the men).

Hence, while surrounding the enemy, order the ones that are in relatively ineffective firing positions like d, e, and f from Doug's system to not fire and merely sit there. Once the shooting HAs run out, switch their roles of bait and shooter. This is a great way to optimize and conserve ammo for maximal number of kills.
