more than eighteen miles from Bibracte, by far the largest and best-stored
town of the Aedui) he thought that he ought to provide for a
supply of corn; and diverted his march from the Helvetii, and advanced
rapidly to Bibracte. This circumstance is reported to the enemy by some
deserters from Lucius Aemilius, a captain of the Gallic horse. The
Helvetii, either because they thought that the Romans, struck with
terror, were retreating from them, the more so, as the day before,
though they had seized on the higher grounds, they had not joined
battle; or because they flattered themselves that they might be cut off
from the provisions, altering their plan and changing their route, began
to pursue and to annoy our men in the rear.

XXIV.--Caesar, when he observes this, draws off his forces to the next
hill, and sent the cavalry to sustain the attack of the enemy. He
himself, meanwhile, drew up on the middle of the hill a triple line of

with the hope of flight, after encouraging his men, joined battle. His
soldiers, hurling their javelins from the higher ground, easily broke
the enemy's phalanx. That being dispersed, they made a charge on them
with drawn swords. It was a great hindrance to the Gauls in fighting,
that, when several of their bucklers had been by one stroke of the
(Roman) javelins pierced through and pinned fast together, as the point
of the iron had bent itself, they could neither pluck it out, nor, with
their left hand entangled, fight with sufficient ease; so that many,
after having long tossed their arm about, chose rather to cast away the
buckler from their hand, and to fight with their person unprotected. At
length, worn out with wounds, they began to give way, and as there was
