II Transf., concr., an army , and properly considered as in motion , on the march (while exercitus is a disciplined army, and acies an army in battle-array) —As soon as the signal for marching was given, the Extraordinarii and the allies of the right wing, with their baggage, first put themselves in motion, then the legions, and last the allies of the left wing, with a part of the cavalry, which either rode behind the army, ad agmen claudendum or cogendum. to close the train, i. e. to keep it to gether or on the side in such an order (composito agmine, non itineri magis apto quam proelio) that it might be easily put into the line of battle, if the enemy ventured to attack it; cf. Sall. J. 46, 6.—An army in close ranks was called agmen justum, Tac. H. 1, 68, or agmen pilatum, Serv. ad Verg. A. 12, 121—When there was no apprehension of the enemy, less care was taken for the protection of the army: agmine incauto, i. e. minus munito, ut inter pacatos, ducebat, sc. consul, Liv. 35, 4.— The order of march was, however, different, according to circumstances and the nature of the ground, Liv. 35, 4; 27, 28; and cf. Smith's Antiq.—Sometimes the army marched in the form of a square, agmen quadratum, with their baggage in the middle, so as to be in battle-array on meeting the enemy; hence agmen quadratum often means the same as acies triplex, an army formed in line of battle , only that the former indicates that they are on the march, and the latter that they are at rest.—Hence, like acies, with the epithet primum , the vanguard , Liv. 34, 28; Tac. Agr. 35: medium, the centre , Liv. 10, 41; Tac. H. 4, 22: extremum, Liv. 34, 28; Tac. H. 2, 100; or, novissimum, the rear , rearguard , Liv. 44, 33; so, extremi agminis, Vulg. Deut. 25, 18: ut inde agmine quadrato ad urbem accederet, marching in a square , Cic. Phil. 13, 8: pariter atque in conspectu hostium quadrato agmine incedere, Sall. J. 100, 1; cf. id. ib. 46, 6, 7: Hannibal agmine quadrato amnem ingressus, Liv. 21, 5; se id. 31, 36; 37, 39: quadrato agmine velut in aciem irent, Curt. 5, 1, 19 al.—Sometimes, esp. in the poets in the plur., in gen. sense, = exercitus or copiae, an army , host , troops : huic tanto agmini dux defuit, Just. 12, 10: occidit Daci Cotisonis agmen, Hor. C. 3, 8, 18: agmina curru Proterit, Verg. A. 12, 329: barbarorum Claudius agmina diruit, Hor. C. 4, 14, 29; so id. S. 2, 1, 14; id. Epod. 17, 9; Ov. M. 3, 535; 5, 151; 161; 6, 423: Del agminum Israël, Vulg. 1 Reg. 17, 45: agmina ejus dispergam, ib. Ezech. 12, 14; 38, 6.—For military service , warfare : rudis agminum Sponsus, Hor. C. 3, 2, 9.—
