Sent a to-be-replenished army of Yari Samurai into Hyuga territory for scouting, got ambushed by, I guess, 210 men which were Ito Yari Ashigaru and Bow Ashigaru. I played the conflict -hard to name this a battle- myself. Bow Ashigaru was climbing a steepness on top of which my men were standing ready in the woods. As I saw them coming, I "rapid-advanced" my men towards them, slaying most and routing the left 40~. Then Yari Ashigaru were left and I charged them as well, killing until only 1 of them could escape the battlefield despite my men being ordered to chase to the last one.

Tactical absurdity of AI or Yari Samurai were too good despite being outnumbered 1 to 3 ?
