Hello, and welcome to a sneaky peek at the first of the Cavalry miniatures for our Spanish Century range.
These nine new 28mm miniatures are design to represent the small number of mounted warriors who accompanied Cortes to the New World. Each of the three new packs contains three fully armoured Knights, mounted on un-barded horses. A majority of packs are sculpted to be equipped with light lances, but the miniatures are to be cast open handed to allow a degree of choice.
The third pack has all its miniatures armed with swords.
