Which battle specifically are you talking about for Conquistadors fighting with cloth armor. no horses, and no artillery or guns? If we're talking about a pitched battle between a small European force and a large Aztec army after La Noche Triste it surely must be Otumba.
But that can't be right, since (primary source alert!) Bernal Diaz del Castillo largely credits the victory to the Spanish cavalry and references an order that the infantry "thrust with their swords, and to pass them clear through the bodies of their opponents" (see
https://www.jrbooksonline.com/Diaz/diaz_part1-ch9.htm).
As for the Romans, the Italians and Carthaginaians were the foes they struggled with the most. They defeated Carthage in the first 2 wars mostly by outlasting and outmobilizing them. They conquered Italy by adding defeated Italians to their army as socii allies, giving them a share of the loot. It's like Goku but with guido motherfuckers.
As for Crusades, let's look at the 2nd Crusade. The Holy Roman Emperor and the French King led armies against the Muslims.
>2nd Dorylaeum
German Crusaders ignore Byzantine advice, get casually btfo by Turkish horse archers
>Laodicea
German Crusaders ambushed, easily killed by Turks
>The Meander
French heavy cavalry fend off Turkish ambush while crossing the river
>Mount Cadmus
French army easily crushed by Seljuks, King flees into the night like a coward
>Damascus
Crusader remnants camp outside Damascus for a long weekend, then give up and go home
Not unreasonable to call these logistical or coordination problems, but also not exactly covering the Crusaders in glory here. If the Crusaders are super soldiers whose superior strength or aryan spirit or whatever leads them to massive victories, why are they getting repeatedly embarrassed by random Turks on the road to the Holy Land?
