During that day Caesar followed the enemy at the usual interval and pitched his camp three miles from theirs. Next day, as the distribution of rations was due in two days' time and he was only seventeen miles from Bibracte, far the largest and richest town of the Aedui, he thought it advisable to secure his food-supply, and therefore diverged from the route that the Helvetii were following and marched towards the town.
[...] The Helvetii, who were following us with the whole of their transport, now parked it all together, and, after repulsing our cavalry, with a battle-line drawn up in very close order, formed a phalanx and climbed towards our first line. [...]
It is quite clear from his own accounts of the early part of his war in Gaul that he was making mistakes and the army was managing to get out of [them] and his first three battles were in one way or another errors in judgement... it is only the sheer guts of the Roman soldier and Caesar's own willingness to go into the frontline and to fight next to the blokes to inspire them that actually wins the battle.
