eas copias impedimenta[4] totius exercitus conlocabant.
[5]Tum legiones quae proxime conscriptae erant totum agmen claudebant.
Equites quoque in omnis partis dimittebantur qui loca explorarent; et
centuriones praemittebantur ut locum castris idoneum deligerent. Locus
habebatur idoneus castris [6]qui facile defendi posset et prope aquam
esset. Qua de causa castra[7] in colle ab utraque parte arduo, a fronte
leniter declivi saepe ponebantur; vel locus paludibus cinctus vel in
fluminis ripis situs deligebatur. Ad locum postquam exercitus pervenit,
alii militum [8]in armis erant, alii castra munire incipiebant. Nam
[9]quo tutiores ab hostibus milites essent, neve incauti et imparati
opprimerentur, castra fossa lata et vallo alto muniebant. In castris
portae quattuor erant ut eruptio militum omnis in partis fieri posset.
In angulis castrorum erant turres de quibus tela in hostis
coniciebantur. [10]Talibus in castris qualia descripsimus Publius a
Caesare exceptus est.

[Footnote 1: /Quae pericula\, object of /vitarent\. It is placed
first to make a proper connection with the preceding sentence.]

[Footnote 2: /ut ... duceret\, Sec. 501.43.]

[Footnote 3: /expeditis\, i.e. without baggage and ready for
action.]

[Footnote 4: /impedimenta\. Much of the baggage was carried in carts
and on beasts of burden, as is shown above; but, besides this, each
soldier (unless /expeditus\) carried a heavy pack. See also picture,
p. 159.]

[Footnote 5: The newest legions were placed in the rear, because
they were the least reliable.]

[Footnote 6: /qui ... posset ... esset\, Sec. 501.45.]

[Footnote 7: /castra\, subject of /ponebantur\.]

[Footnote 8: /in armis erant\, _stood under arms_.]

[Footnote 9: /quo ... essent\. When is /quo\ used to introduce a
purpose clause? See Sec. 350.I.]

[Footnote 10: /Talibus in castris qualia\, _in such a camp as_.
It is important to remember the correlatives /talis ... qualis\,
_such ... as_.]

LXX. THE RIVAL CENTURIONS

Illis in castris erant duo centuriones,[1] fortissimi viri, T. Pullo et
L. Vorenus, quorum neuter alteri virtute[2] cedere volebat. Inter eos
iam multos annos infensum certamen gerebatur. Tum demum finis
controversiae hoc modo[3] factus est. Die tertio postquam Publius
pervenit, hostes, maioribus copiis coactis, acerrimum impetum in castra
fecerunt. Tum Pullo, [4]cum
