There are several points in which this rendering must be improved.
Thus:--
(a) _Affair_ for +res+ is too vague. You will remember what was said about +res+ in Sentence I. of Part I. pp. 33, 34.
(b) You must try to express more strongly the contrast in generalship between Hannibal and a mere centurion. Thus:--
'_The +result+ was not doubtful, considering that the contest was between a general such as Hannibal and a (mere) centurion; and between two armies, the one grown old in victory, the other consisting entirely of raw recruits, and for the most part undrilled and half-armed._'
+II.+ +Ut conspecta inter se agmina sunt, et neutra pars detrectavit pugnam, extemplo instructae acies.+
(i.) _Vocabulary._--
+neuter+ = ne + uter (+uter = eu-ter+ or +quo-ter-us+ = comparative in form of +quis+), _neither of two_.
+detrectavit+ = _declined_ (+de + traho+, draw-off).
+extemplo+ = _immediately_. +Ex + templum+ (dimin. +tempulum+).
+templum+ v+tem+ = cut; cf. t??? = prop. a _section_. So
(a) a _space marked_ out, a consecrated place, a _temple_.
(b) a _portion of time_; cf. _extempore_.
(ii.) _Translation._--This sentence again is quite simple (in form very similar to Sentence I.), consisting of one main statement, +extemplo instructae acies+, and an introductory subordinate statement of _time_ introduced by +ut+ = _when_.
_'When the armies came in sight of each other, and neither side declined battle, the ranks were at once drawn up in fighting order.'_
[14]+III.+ +Pugnatum tamen, ut in nulla pari re, duas amplius horas, concitata et, donec dux stetisset, Romana acie.+
[Footnote 14: Weissenborn and Muller read:--Pugnatum tamen, ut in nulla pari re, _diu_: duas amplius horas con_stitit pugna spe con_citante, donec dux stetit, Romana_m_ acie_m_.]
(i.) _Vocabulary._--
+concitata+ = _stirred-up_, _roused_. +con + ci-eo+; cf. _+ex-cite+_, _+incite+_, +ci-tus+ = _put in motion_, _swift_, &c.
(ii.) _Translation._--This sentence is not quite so simple and needs care. Notice--
(a) +Pugnatum (est).+ The Impersonal Pass. serves as the principal subject and predicate.
(b) +ut in nulla pari re.+ +ut+ is here not a _conjunction_ but a relative _adverb_ of manner, referring the assertion +pugnatum duas amplius horas+ to the particular circumstance--_i.e._ of a battle fought under very unequal conditions. This use of +ut+ = _considering_ occurs frequently--_e.g._ +consultissimus vir ut in illa quisquam esse aetate poterat+ (Livy). Cf. also p. 124, l. 19. [[Selection C17, "ut in re trepida"]]
(c) +concitata Romana acie+ is clearly ablative absolute. To make quite sure that you understand the logical connection of the thought conveyed by this sentence, you may consult the detailed analysis on page 47.
_In spite of its being such an unequal match, the battle was maintained for more than two hours; the Roman army (as well as [+et+] the enemy's) being roused (to great exertions) so long as their leader survived._
+IV.+ +Postquam is non pro vetere fama solum, sed etiam metu futuri dedecoris, si sua temeritate contractae cladi superesset, obiectans se hostium telis cecidit, fusa extemplo est Romana acies.+
(i.) _Vocabulary._--
+dedecoris+ = of _dis-grace_, for +de+ in composition = separation, and so _removal_ of the fundamental idea. Cf. _un-_, _dis-_, _e.g._ +dis-par+ = _un_-equal.
+contractae+ = _brought on_, _caused_. +con + traho+ = _bring about_, _cause_.
(ii.) _Translation._--The meaning of this sentence should be quite plain to you if you notice carefully that
(a) the principal verb is +fusa est+, and the principal subject +Romana acies+, and
(b) that +Postquam ... cecidit+ is a subordinate clause of _time_ modifying the action of the principal verb +fusa est+.
It would perhaps be well to translate at first literally:--
_After that he, not only out of regard for_ (+pro+) _his old fame, but also from fear of future disgrace, if he should survive a disaster brought about by his own rashness, exposing himself to the weapons of the enemy fell, the Roman army was at once routed._
You will see that this rendering, though verbally correct, is not English, and must be considerably altered before it can be called a good translation. Thus:--
(a) _It is too long._ You can remedy this by taking +postquam ...
cecidit+ as one complete sentence, and +fusa ... acies+ as another.
(b) _Exposing himself._ Better _exposed himself to ... and_. Notice here the strictly accurate use of the Pres. participle in Latin.
(c) '+future+' may be omitted, as tautological[15] in English. Cf. our inexact idiom '_he promised to come_' (Lat. '_that he would come_').
[Footnote 15: _i.e._ needless repetition (ta?t? ???e?? = to say the same thing).]
_At last, both for the sake of his old renown and from the fear of disgrace should he survive a disaster brought on by his own rashness, he threw himself among the enemy's darts and was slain. The Roman army was routed in a moment._ --Church and B.
+V.+ +Sed adeo ne fugae quidem iter patuit omnibus viis ab equite insessis, ut ex tanta multitudine vix mille evaserint, ceteri passim alii alia peste absumpti sint.+
(i.) _Vocabulary._--
+patuit+ = _was open_. Cf. +pate-facio+ = _to make open_; +pat-ulus+ = _open_, _spread out_; +pat-era+ = _a broad, flat dish_. English, _patent_.
+insessis+ = _occupied_; +in + sed-eo+ = _sit upon_--so, _occupy_.
+passim+ = _hither and thither_, _far and wide_, formed from +passus+ (+pando+), _expand_.
(ii.) _Translation._--This sentence resembles in form Sentence IV., with one principal verb +patuit+, and a principal subject +iter+, and a subordinate clause of _result_, +ut ... absumpti sint+, modifying the action of the principal verb +patuit+. You may conveniently break up this sentence into two, by beginning a new sentence with +Ceteri+.
Thus:--
_So completely closed against them was every chance of escape, all the roads being beset by cavalry, that out of so numerous a host hardly a thousand escaped. The rest perished as they fled, some by one death and some by another._
Before laying aside these two passages, you should pay attention to the following points:--
(i.) _Vocabulary._--Besides carefully noticing _new_ words, try to form groups of _cognates_ (i.e. _related words_). One of the best ways to enlarge your vocabulary is to group together _words of common origin_, and to add to each, where you can, derivative and cognate English words.
