The pass grew more and more like some huge rift in the mountain which seemed to have been split open by lightning, whose form the deep way had in some degree assumed.
For a few hundred yards the train would be going straight, till an acute angle was reached, when for a distance the line would be forced to almost double back to another point and double back again. It was a savage kind of zig-zag which always led higher and higher, while as they neared the top, the snow grew deeper and the walls on either side closer, while these were not only perpendicular but in many cases actually overhanging.
The horses’ hoofs and the chariot wheels at last sank in so far, in spite of their being unburdened, that the leader commanded a halt for rest, and as this order was obeyed, Marcus, from where he stood panting, with one hand that had been used to push forward the chariot resting now upon its back, felt awe-stricken at the strange silence that for a moment or two dwelt deep down in the jagged furrow, before it was broken by the peculiar panting of exhausted men and steeds who were striving to regain their wind, while a mist formed by the breath rendered everything indistinct along the line, as it rose visibly on high.
For plainly now from the front came the sound of contending warriors, apparently close at hand, though far enough away as yet, but increased in power by being condensed into a narrow space, as it reverberated along the pass from wall to wall.
But not alone from the front; fainter, but minute by minute gathering strength, similar sounds came from the rear, telling plainly enough of the fight that was going on where the foot-men were holding back the advancing enemy during a steady retiring movement that could hardly be called a retreat.
“I don’t like this, boy,” whispered Serge, who was resting against the other side of the chariot.
“Are we being beaten, Serge?” asked Marcus.
“Oh, no, boy; they can’t beat us. But they have got us in this narrow gully where only a few men back and front can fight at once. Why, you know for yourself here are all our mounted troops and us with the chariots doing nothing but struggle through the snow, and never getting a spear thrust at anyone. That’s why I say I don’t like it. I want to be doing something, and when I say that it’s just what everyone feels as it makes his blood hot. I say, boy, you don’t feel cold now?”
“Cold?” cried Marcus. “Oh, no; I only want to keep going on.”
“Wait a bit, boy, and you shall have enough of that. Our captain isn’t letting us rest just to amuse ourselves. It will be forward directly, and quite soon enough for the horses, for it’s hard work for them; and I say,” continued the old soldier, jocosely, “this is a bit of a change for you, my boy. You never thought there was a place like this so near to Rome, where the people are lying grumbling now because it is so hot that they cannot sleep, and panting just like old Lupe there.”
