Btw, still on the topic of weapons, seeing as this is a fantasy realm with I assume at least a few fantasy beast I'd imagine some weapons would different then anything from our world. 

After all, you'd want specially crafted tools/tactics to deal with wyverns or a Minotaur. 

And that's not even getting into the realm of magic, A well placed fire ball or most AOE spells would be a nightmare for a tight formation. Just imagine what an otherwise average spell like chain lightening would do to a column. Partly why I wanted to know how magic worked in this setting. Allot of fantasy elements would reshape a battlefield from what we might recognize from normal middle age battles.
