heavy cavalry engaging heavy cavalry

[Dan Howard]

BTW - the 17th century saw a renaissance of cavalry, which again had a significant role in battles.

There was no "renaissance" in the 17th century. Heavy cavalry never declined in utility or importance, they just changed tactics over the centuries.

Start with DeVries and then read Anne Curry's book on Agincourt. Andrew Ayton's Knights and Warhorses is also an important reference.
