Halting the Iberian Advance

Arnulf gazed into the distance; what he saw was the glimmer of an army's iron armor. Roughly three hundred yards away, on the fields of Andalusia marched well over 10,000 Iberian Catholics. However, they were dreadfully unaware that within firing range were two hundred and fifty members of the Granadan Royal Guard.

Why were they unaware, you might ask? The reason was quite simple, Arnulf had instructed the men beneath his command to paint their armor and clothing with mud.  While the Granadan Royal Guard was equipped with mirror pattern armor protecting their vitals, underneath it was a series of green tunics that represented the colors of Al-Andalus. The tunics and armor worn over it were now stained in the earthy tones of the mud, creating a decent enough camouflage.
