Hello /r/AskHistorians,

I was recently reading two books of the same series one titled Battles of the Medieval World, the other Battles of the Oriental World. My question came to being because while the Battles of the Oriental World delt a good deal about how primitive gunpowder weapons were fielded with spears and samurai, the Medieval World title never mentions them being fielded.

So my question is, are there historical battles in Medieval europe where gunpowdered weapons were fielded along with spears and knights? I have some knowledge about hand cannons being used in eastern Europe by the turks and Ottomans so I believe there is at least some basis. However when I think about historic European warfare there is a drastic shift between armored knights and uniformed collumns of rifles muskets, and nothing inbetween.
