Cataphract, Clibanarii, whatever, against Infantry

[Aulus Perrinius]

I apologize if this is the wrong place

My question is how many battles do we know of where Cataphracts (Fully armoured men on armoured horses with lances, maces and bows, and let's forget about the big terminology debate for now) fought solid infantry (Any side/instance you can think of) and how did they perform?

Also as an aside question what were the size of Cataphract horses?

The intricacy and obtuseness of your two-pronged question must account for the lack of answers.

Ouch, dude there's no need to be insulting
