Fortunately Hannibal, moved by his doubts, had sent his cavalry and baggage on first. The attack fell on the infantry, and with a body of these he forced his way to the summit of one of the cliffs above the defile, drove away the foe, and held it while the army made its way slowly on. As for the elephants, they were safe from attack. The very sight of these huge beasts filled the barbarians with such terror that they dared not even approach them. There was no further peril, and on the ninth day of its march the army reached the summit of the Alps. It was now the end of October. The grass and flowers which carpet that elevated spot in summer had become replaced by snow. In truth, the climate of the Alps was colder at that period than now, and snow lay on the higher passes all through the year. The soldiers were disheartened by cold and fatigue. The scene around them was desolate and dreary. New perils awaited their onward course. But no such feeling entered Hannibal's courageous soul. Fired by hope and ambition, he sought to plant new courage in the hearts of his men. "The valley you see yonder is Italy," he said, pointing to the sunny slope which, from their elevated position, appeared not far away. "It leads to the country of our friends, the Gauls; and yonder is our way to Rome." Their eyes followed the direction of his pointing hand, and their hearts grew hopeful again with the cheerfulness and enthusiasm of his words. Two days the army remained there, resting, and waiting for the stragglers to come up. Then the route was resumed. The mountaineers, severely punished, made no further attacks; but the road proved more difficult than that by which the ascent had been made. Snow thickly covered the passes. Men and horses often lost their way, and plunged to their death down the precipitous steep. Onward struggled the distressed host, through appalling dangers and endless difficulties, losing men and animals at every step. But these troubles were trifling compared with those which they were now to endure. They suddenly found that the track before them had entirely disappeared. An avalanche had carried it bodily away for about three hundred yards, leaving only a steep and impassable slope covered with loose rocks and snow. A man of less resolution than Hannibal might well have succumbed before this supreme difficulty. The way forward had vanished. To go back was death. It was impossible to climb round the lost path, for the heights above were buried deep in snow. Nothing remained but to perish where they were, or to make a new road across the mountain's flank.
