N.B.--+suorum+, reflexive, must be identical with the subject of +premebant+.
Now translate _{ Though}{ When} the enemy’s line had been routed and put to flight on their left wing, on their right wing, owing to their great numbers, they were pressing hard upon our line._
+V.+ +Id cum animadvertisset Publius Crassus adulescens, qui equitatui praeerat, quod expeditior erat quam hi qui inter aciem versabantur, tertiam aciem laborantibus nostris subsidio misit.+
+animadvertisset+ = +animum + ad + verto+ = _to turn the mind to, to observe_.
+adulescens+ = here like our _junior_, to distinguish him from his father, Marcus Crassus the triumvir.
+expeditior+ = _more free_ (+ex + pes+ = _foot-free_; so +impeditus+ = _hampered_, _hindered_).
+versabantur+--(+verso+ frequent. of +verto+) = _turn this way and that_; so +verso-r+ dep. = _turn oneself_, _engage in_, _be_, according to the context.
(ii.) _Translation._--This sentence is more involved, ‘periodic’[8] in style. You will see on p. 23 how much help can be given by a more detailed analysis. [[Demonstration I: Table]]
[Footnote 8: See Introduction, pp. 7-9, § 11.] [[Introduction 11. Help through a Study of the Period in Latin.]]
Now, as before, bracket the subordinate clauses thus:--
+1.+ +Id ... adulescens+ +2.+ +qui ... praeerat+ +3.+ +quod ... versabantur+
and then the only principal verb is +MISIT+. Underline this. Next underline the principal subject, clearly +P. CRASSUS+, which is also the subject of clause 1. Then, _outside the brackets_, the only possible object is +ACIEM+: underline this.
Now analyse, as on p. 23. [[Demonstration I: Table]]
(a) Write down +CRASSUS+, +MISIT+, +ACIEM+.
(b) Place alongside these their proper enlargements.
(c) If necessary, analyse separately all subordinate clauses--_e.g._ A1, A2, A3 in example on p. 23.
You should now be able to translate without any difficulty; only take care to arrange the enlargements so as to make the best sense and the best English. Thus: _When Publius Crassus the younger, who was in command of the cavalry, had observed this, he sent the third line to the help of our men who were hard pressed, as he was more free to act than those who were engaged in action._
+VI.+ +Ita proelium restitutum est.+ _In this way the battle was restored._
