The Equilord and his race, though no match for the White King’s enhanced and magically assisted army were no slouches in battle in their glory days before the rise of the Army of the White Wing and the Equilords amalgamation with it.
History will all show the Equilord as a peaceful and enlightened race but not one to shirk away from a battle if needed to defend itself.
The equine based lifeforms had also the knowledge and capacity to perform quite a few battle tricks of their own and it is these that the White King was so keen to have them as valued allies.
One major battle tactic of the infantry was to create illusions bordering on hallucinogenic, these would include the army morphing into schools of Hippocampus (horse/fish) complete with massive waves forming before it.
This of course was affective as any trebuchet or archery onslaught to the hapless foot soldiers usually facing the field opposite them and cause the opposition to scatter in wild flight.
