XXXIX

Now anyone who carefully studies the whole of this passage, must perceive how useful and necessary it is for a captain to know the nature of places, which knowledge had Decius not possessed he could not have decided that it would be for the advantage of the Roman army to occupy this hill; nor could he have judged from a distance whether the hill was accessible or no; and when he reached the summit and desired to return to the consul, since he was surrounded on all sides by the enemy, he never could have distinguished the path it was safe for him to take, from those guarded by the foe. For all which reasons it was absolutely essential that Decius should have that thorough knowledge which enabled him by gaining possession of this hill to save the Roman army, and to discover a path whereby, in the event of his being attacked, he and his followers might escape.
