Roman baggage camels

[D B Campbell]

What does he say the epibatae are doing? (I don't have the full text).

De mun. castr. 29: ... Camelis cum suis epibatis singulis pedes V adsignabimus. Tendere debebunt, si in hostem exituri erunt, in praetentura iuxta classicos, si ad praedam portandam praesto erunt, intra quaestorium tendere debebunt.

"We will assign 5 feet [i.e. space in the camp] to each camel with its epibata. If the camels are to be used in action, they should camp in the praetentura [i.e. the front part of the camp] near the marines, but if they are there to carry the booty, they should camp in the quaestorium [i.e. the central area beside the praetorium]."
