It is too much, perhaps, to say that they settled; the greater part of them continued wandering and fighting, sometimes amalgamating with the peoplets they encountered, sometimes chasing them and exterminating them, whilst themselves were incessantly pushed forward by fresh bands coming also from Gaul.

Thus marching and spreading, leaving here and there on their route, along the rivers and in the valleys of the Alps, tribes that remained and founded peoples, the Gauls had arrived, towards the year 340 B.C., at the confines of Macedonia, at the time when Alexander, the son of Philip, who was already famous, was advancing to the same point to restrain the ravages of the neighboring tribes, perhaps of the Gauls themselves.

From curiosity, or a desire to make terms with Alexander, certain Gauls betook themselves to his camp.

He treated them well, made them sit at his table, took pleasure in exhibiting his magnificence before them, and in the midst of his carouse made his interpreter ask them what they were most afraid of.
"We fear nought," they answered, "unless it be the fall of heaven; but we set above everything the friendship of a man like thee." "The Celts are proud," said Alexander to his Macedonians; and he promised them his friendship.

On the death of Alexander, the Gauls, as mercenaries, entered, in Europe and Asia, the service of the kings who had been his generals.
