Battle of Aux-en-Provence
The two Armies met. Each on their side of the stream. A Majority of the Gallic Army moved forward, but did not cross. At the same time, the Roman Legions did the same. The Gallic soldiers did not cross, which gave the Romans a heavy advantage. They threw their pila's, inflicting a lot of front line casualties as a result of the range. The Gallic Army still their ground, and did not cross. The Romans did the exact opposite. They piled into heavy formation, spearheading the stream and hurrying across the stream. The Gallic forces engaged immediately, and their cavalry came from the flanks.
The Legions stood fast, and managed to unhorse many of the cavalrymen with their triangle formation as it was nearly impossible to completely penetrate. The Gallic forces continued to fight, but began to break. When the front line fell, Gallic Reserves of more than 5,000 men charged in. The Romans continued to fight, and their cavalry had safely crossed the river and began to harass the Gallic flanks.
In the end, the Romans managed to pull of a victory, strictly from their penetrating formations, and their more effective weapons. But it was not without cost.
