Sure. I'm sure you think of it during most medieval show that has some sort of warfare, some variation of it is almost always featured, though as far as I know tactics similar to that had been used long before that particular battle.
Encirclement Is very old tactics the medieval period actually used this and much more modern tactics effectively combined arms warfare.
Encirclement was just the outcome. What was really interesting to me in the battle of Cannae was the feigned retreat.
