Total War: Shogun 2 

"Battle of Tsukushi Fields 1550"
The concept of this battle was to bait the numerically superior enemy into attacking my defensive position on the hill, where I had a strategic advantage. This was done by using my cavalry to attack their archers and fake a retreat with my general, in the hopes they would pursue me.
Once it became apparent that my spear wall would not give way, the enemy forces lost morale and retreated, suffering heavy losses.
