Thanks guys, my main units were initally for Asturias and are in Blue and Gold, when doing red and gold I was aware that a number of Kingdoms and regions of Spain used this colour scheme, but wanted to a put a name to the force that made it slightly different. Count Berenger of Barcelona fell foul of El Cid a couple of times and had theis colour scheme for his flag so hence they are Catalonian troops of the Count of Barcelona. But of course any other Spanish knights you like at the same time.
Thanks for the comments.
