XXI. The Romans accordingly awaiting the enemy's attack, and coming to close quarters with them, checked their advance up the hill, and the barbarians, being hard pressed, gradually retreated to the plain, and while those in the van were rallying on the level ground, there was a shout and confusion in the rear. For Marcellus had not let the critical moment pass by, but when the shouts rose above the hills, bidding his men spring from their ambush at a rapid pace and with loud shouts he fell on the enemy's rear and began to cut them down. Those in the rear communicating the alarm to those in front of them, put the whole army into confusion, and after sustaining this double attack for no long time, they broke their ranks and fled. In the pursuit the Romans took prisoners and killed to the number of above one hundred thousand:[87] they also took their tents, waggons, and property, all which, with the exception of what was pilfered, was given to Marius, by the unanimous voice of the soldiers. But though he received so magnificent a present, it was thought that he got nothing at all proportioned to his services, considering the magnitude of the danger. Some authorities do not agree with the statement as to the gift of the spoil, nor yet about the number of the slain. However, they say that the people of Massalia[88] made fences round their vineyards with the bones, and that the soil, after the bodies had rotted and the winter rains had fallen, was so fertilised and saturated with the putrefied matter which sank down into it, that it produced a most unusual crop in the next season, and so confirmed the opinion of Archilochus[89] that the land is fattened by human bodies. They say that extraordinary rains generally follow great battles, whether it is that some divine power purifies the ground, and drenches it with waters from heaven, or that the blood and putrefaction send up a moist and heavy vapour which condenses the atmosphere, which is lightly moved and readily changed to the greatest degree from the smallest cause.
