They were troublesome neighbours, accustomed to pillage by land and by sea: the Pisans and Massiliots suffered no little injury from their incursions and their piracies.

But no permanent results were gained amidst these constant hostilities, or perhaps even aimed at; except apparently that, with a view to have a communication by land with Transalpine Gaul and Spain in addition to the regular route by sea, the Romans endeavoured to clear the great coast road from Luna by way of Massilia to Emporiae, at least as far as the Alps--beyond the Alps it devolved on the Massiliots to keep the coast navigation open for Roman vessels and the road along the shore open for travellers by land.

The interior with its impassable valleys and its rocky fastnesses, and with its poor but dexterous and crafty inhabitants, served the Romans mainly as a school of war for the training and hardening of soldiers and officers.
Corsica Sardinia Wars as they are called, of a similar character with those against the Ligurians, were waged with the Corsicans and to a still greater extent with the inhabitants of the interior of Sardinia, who retaliated for the predatory expeditions directed against them by sudden attacks on the districts along the coast.

The expedition of Tiberius Gracchus against the Sardinians in 577 was specially held in remembrance, not so much because it gave "peace" to the province, as because he asserted that he had slain or captured as many as 80,000 of the islanders, and dragged slaves thence in such multitudes to Rome that "cheap as a Sardinian" became a proverb.
Carthage In Africa the policy of Rome was substantially summed up in the one idea, as short-sighted as it was narrow-minded, that she ought to prevent the revival of the power of Carthage, and ought accordingly to keep the unhappy city constantly oppressed and apprehensive of a declaration of war suspended over it by Rome like the sword of Damocles.

The stipulation in the treaty of peace, that the Carthaginians should retain their territory undiminished, but that their neighbour Massinissa should have all those possessions guaranteed to him which he or his predecessor had possessed within the Carthaginian bounds, looks almost as if it had been inserted not to obviate, but to provoke disputes.
