When the Padus was in sight and night began to fall they judged it expedient to entrench a camp. The labour, new as it was to the soldiery of the capital, broke their spirits. All the oldest among them began to inveigh against their own credulity, and to point out the difficulty and danger of their position, if on those open plains Cæcina and his army were to surround their scanty forces. By this time more temperate language was heard throughout the camp, and the tribunes and centurions, mixing with the troops, suggested commendations of the prudence of their general in selecting for the rallying point and basis of his operations a colony rich in military strength and resources. Finally, Spurinna himself, not so much reproaching them with their error as exposing it by his arguments, conducted them all back to Placentia, except some scouts whom he left, in a less turbulent temper and more amenable to command. The walls were strengthened, battlements were added, and the towers were raised in height. It was not only of the implements of war that provision and preparation were made, but of the spirit of subordination and the love of obedience. This was all that was wanting to the party, for they had no reason to be dissatisfied with their courage.
