Above all, he found that other antagonists were opposed to him. Taught by fearful experience, the Romans adopted a more judicious system of conducting the war, placed none but experienced officers at the head of their armies, and left them, at least where it was necessary, for a longer period in command. These generals neither looked down on the enemy's movements from the mountains, nor did they throw themselves on their adversary wherever they found him; but, keeping the true mean between inaction and precipitation, they took up their positions in entrenched camps under the walls of fortresses, and accepted battle where victory would lead to results and defeat would not be destruction. The soul of this new mode of warfare was Marcus Claudius Marcellus. With true instinct, after the disastrous day of Cannae, the senate and people had turned their eyes to this brave and experienced officer, and entrusted him at once with the actual supreme command. He had received his training in the troublesome warfare against Hamilcar in Sicily, and had given brilliant evidence of his talents as a leader as well as of his personal valour in the last campaigns against the Celts. Although far above fifty, he still glowed with all the ardour of the most youthful soldier, and only a few years before this he had, as general, cut down the mounted general of the enemy(1)--the first and only Roman consul who achieved that feat of arms. His life was consecrated to the two divinities, to whom he erected the splendid double temple at the Capene Gate--to Honour and to Valour; and, while the merit of rescuing Rome from this extremity of danger belonged to no single individual, but pertained to the Roman citizens collectively and pre-eminently to the senate, yet no single man contributed more towards the success of the common enterprise than Marcus Marcellus.
