heavy cavalry engaging heavy cavalry

[ValentinianVictrix]

Vegetius wrote that Roman Clibanarii were better at fighting infantry. I suspect this was due to the fact that less heavily armoured cavalry could easily evade or break off from combat with them. However, in conversation with those who are more knowledgeable about Eastern and Far Eastern warfare they state that those versions of Catafractarii/Clibanarii were effective against both infantry and cavalry.
