Res Gestae

The furious madness of this onset

so angered our army that it could not brook it, and as the savages hotly menaced the emperor (as was said), they took the form of a wedge (an order which the soldier’s naive parlance calls the pig’s head,)[*](Vegetius, iii. 19, says that the soldiers gave the name caput porcinum to the cuneus, a V-shaped formation, with the apex towards the enemy. It was the opposite of the forceps, or forfex (xvi. 11, 3).) and scattered them with a hot charge; then on the right our infantry slaughtered the bands of their infantry, while on the left our cavalry poured into the nimble squadrons of their cavalry.
