This is all that I could find in the UBB archives. There is an illustration in one of the posts showing a man on horseback surrounded by attendents. He carries both a pata and a katar, and a few of the attendants carry katars in their belts (as well as various swords in their hands). No one is wearing armor, but the scene looks more like an afternoon ride in the country than a march to war.
