"There are four Divisions, at present, in an Army Corps," replies Cocon; "the number changes, sometimes it is three, sometimes five. Just now, it's four. And each of our Divisions," continues the mathematical one, whom our squad glories in owning, "includes three R.I.--regiments of infantry; two B.C.P.--battalions of chasseurs pied; one R.T.I.--regiment of territorial infantry--without counting the special regiments, Artillery, Engineers, Transport, etc., and not counting either Headquarters of the D.I. and the departments not brigaded but attached directly to the D.I. A regiment of the line of three battalions occupies four trains, one for H.Q., the machine-gun company, and the C.H.R. (compagnie hors rang [note 2]), and one to each battalion. All the troops won't entrain here. They'll entrain in echelons along the line according to the position of the quarters and the period of reliefs." "I'm tired," says Tulacque. "We don't get enough solids to eat, mark you. We stand up because it's the fashion, but we've no longer either force or freshness." "I've been getting information," Cocon goes on; "the troops--the real troops--will only entrain as from midnight. They are still mustered here and there in the villages ten kilometers round about. All the departments of the Army Corps will first set off, and the E.N.E.--elements non endivisionnes," Cocon obligingly explains, "that is, attached directly to the A.C. Among the E.N.E. you won't see the Balloon Department nor the Squadron--they're too big goods, and they navigate on their own, with their staff and officers and hospitals. The chasseurs regiment is another of these E.N.E." "There's no regiment of chasseurs," says Barque, thoughtlessly, "it's battalions. One says 'such and such a battalion of chasseurs.'" We can see Cocon shrugging his shoulders in the shadows, and his glasses cast a scornful gleam. "Think so, duck-neb? Then I'll tell you, since you're so clever, there are two--foot chasseurs and horse chasseurs." "Gad! I forgot the horsemen," says Barque.
