That was enough for the three Gauls, who turned at once and fled, for a rank of the Roman soldiers was advancing, and as they closed up, Marcus and Serge were free to take their places in the line once more as if nothing had happened, and the advance guard steadily pressed on.
There was a fortnight’s hard fighting carried on day by day, with a succession of halts for the formation of camps in the strongest positions that offered themselves as havens of refuge against a teeming enemy which refused to be crushed and constantly swarmed round the retiring Roman army, perfectly reckless of life, and apparently content with the smallest advantages that they could gain.
Rolled back one day by a Roman charge, the Gauls gathered together again during the night to attack and harass the retiring troops; but all was in vain, for step by step Caius Julius carried all before him, and the help that Marcus had been sent to seek gradually drew nearer to the beleaguered force till one morning, as the army came into position to continue its march, Marcus was passing along the ranks and halted by Serge, who eagerly drew his attention to the glittering snow upon the mountains a mile or two in front.
“See that?” he cried. “Why, before long we shall reach that stream and be marching into that great hollow among the mountains where we stopped that day with the chariot to see our general lead his men up into the pass. Why, to-night we ought to be camping there amongst the snows; and a nice change too, my boy, for its been rather hot work for about a fortnight now.”
“Yes,” said Marcus, quietly; “but according to the tidings the scouts have been bringing in all through the night, the Gauls are swarming in that great amphitheatre between here and the pass, and all promises for the biggest fight that the army has yet had.”
Serge took off his helmet and rubbed one ear thoughtfully, as he gazed straight before him in the direction of the pass.
“Well,” he said, slowly, “I shouldn’t wonder if such a fight did come off, and if it does it will be hard and fierce. I shouldn’t wonder if it is what your father means. That used to be the way we went on: he planned where the fight was to be, and Caius Julius went on and won. I remember every bit of that amphitheatre place, and what a death trap it seemed. You know the captain would not stay in it when the Gauls had surrounded him, but left the way clear for us to go for the help we’ve brought, and led his force right up into the pass so as to make the enemy follow him. Now our generals are scheming to get the Gauls, who have kept on attacking us front, rear and flanks, right into that amphitheatre of a place in the mountains, where they mean, so it seems, to make a stand and stop our getting up by the pass—for that’s what they think we mean to do—so as to join forces with him who is holding it still.”
“But is he holding it still?” said Marcus. “The scouts that were sent out last night as soon as it was dark have not yet returned.”
“Yes they have,” said Serge, quickly. “I saw them come back an hour ago, and make for the general’s headquarters.”
Serge was right, for one of his comrades had heard the result of their investigation, the news they brought back being that their leader was still holding the pass, and, what was more, he was well supplied with provisions, for the country people on the farther slope, realising the strength of the Roman general’s position, had judged it best to accept the conquest, and, making friends, had kept up an ample supply of food, so that the little force which kept the gateway into Gaul and commanded the approaches on either side, had had no greater difficulties to contend with than an occasional attack on the part of the enemy.
