[2] When Bath began playing wargames set in the ancient period, the only miniatures available were German flats which were difficult to procure.
In 1966, Featherstone published Bath's rules for ancient, medieval, and 18th century warfare in three separate pamphlets, part of a set of rulebooks covering eight historical epochs.
They have been described by Kevin Large as "not intended for aggressive competitive play, but for a fast moving enjoyable game".
[3] This is, however, disputed by others on the grounds that the Bath rules continued to be played extensively for a time after flats had been made obsolete by solids.
[10] He wrote a version of his rules designed for solid figures which was published as "Peltast and Pila"[11] in 1976.
