Well, the thing is, they ran out of money, so I had to use regular units. When (during the battle with the outpost) I realized that the Inquisitors would defeat at least 70% of the army (and all the ranged damage dealers), I teleported the Horsemen to them, so they could at least stand in defense for a couple of turns while I finished off the Knights, who were relentlessly harassing the Ents.

Ugh, I reread it, remembered - I didn't teleport the Unicorn, they successfully ran to the Inquisitors (during the battle with the outpost). Teleport doesn't work through a wall. (A small but significant detail)
