From: The History of Rome, by Theodor Mommsen
Translated with the sanction of the author by William Purdie Dickson
But, as neither the Romans nor the Africans had brought with them sufficient forces of their own, the war necessarily became on both sides a struggle to gain partisans, which was decided rarely by solid attachment, more usually by fear, money, or accident, and which, when it seemed about to end, resolved itself into an endless series of fortress-sieges and guerilla conflicts, whence it soon revived with fresh fury.
Armies appeared and disappeared like sandhills on the seashore; on the spot where a hill stood yesterday, not a trace of it remains today. In general the superiority was on the side of the Romans, partly because they at first appeared in Spain as the deliverers of the land from Phoenician despotism, partly because of the fortunate selection of their leaders and of the stronger nucleus of trustworthy troops which these brought along with them.
It is hardly possible, however, with the very imperfect and--in point of chronology especially--very confused accounts which have been handed down to us, to give a satisfactory view of a war so conducted.
