Xenophon,
Anabasis — Book 6, Chapter 3
“ The Thracians, having achieved this success, kept up a continual shouting and clatter of conversation to one another during the night; but with day-dawn they marshalled themselves right round the knoll on which the Hellenes were encamped--both cavalry in large numbers and light-armed troops--while every minute the stream of new-comers grew greater. Then they commenced an attack on the heavy infantry in all security, for the Hellenes had not a single bowman, javelin-man, or mounted trooper amongst them ”
