"The projectile just keeps going after hitting the target."

There was a story from Agincourt (or it could have been Crecy) about a french knight that was hit in his leg as he sat on his horse. The arrow punched through his armor, his thigh, the saddle and hit his horse. The horse wheeled around and another arrow hit the knight's other leg and repeated the process. The knight was stapled to his horse by arrows.

I meant Agincourt, not Crecy.

Plate armor came later and was pierced by crossbows which frequently used bronze bolts.

Very bad news.
