“Suppose, sir,” he said, “that we ford the river just below the trestle.  It will deceive them and we’ll be half way across before they suspect the change.”

“A good plan, Mr. Mason,” said Colonel Newcomb.  “We’ll try it.”

Word was quickly passed along the line that they should turn to the left as they approached the trestle, march swiftly down the slope, and dash into the stream.  As fast as they reached the other side of the ford the men should form upon the bank there, and with their rifles cover the passage of their comrades.

The skeleton work of the trestle now rose more clearly into view.  The rain had almost ceased and faint rays of moonlight showed through the rifts where the clouds had broken apart.  The boys distinctly heard the gurgling rush of waters, and they also saw the clear, bluish surface of the mountain stream.  The same quickening of light disclosed the Southern force on their right flank and rear, only four or five hundred yards away.  Dick’s hasty glance backward lingered for a moment on a powerful man on a white horse just in advance of the Southern column.  He saw this man raise his hand and then command the men to fire.  He and twenty others under the impulse of excitement shouted to the regiment to drop down, and the Northern lads did so.

Most of the volley passed over their heads.  Rising they sent back a return discharge, and then the head of the columns rushed into the stream.  Dick felt swift water whirling about him and tugging at his body, but it rose no higher than his waist, although foam and spray were dashed into his face.  He heard all around him the splashing of his comrades, and their murmurs of satisfaction.  They realized now that they were not only able to retreat before a much superior force, but this same stream, when crossed, would form a barrier behind which they could fight two to one.

The Confederate leader, whoever he might be, and Dick had no doubt that he was the redoubtable Turner Ashby, also appreciated the full facts and he drove his whole force straight at the regiment.  It was well for the young troops that part of them were already across, and, under the skillful leadership of Colonel Newcomb, Major Hertford, and three or four old, regular army sergeants, of whom the best was Whitley, were already forming in line of battle.

“Kneel,” shouted the colonel, “and fire over the heads of your comrades at the enemy!”

The light was still growing brighter.  The rain came only in slight flurries.  The clouds were trooping off toward the northeast, and the moon was out.  Dick clearly saw the black mass of the Southern horsemen wheeling down upon them.  At least three hundred of the regiment were now upon the bank, and, with fairly steady aim, they poured a heavy volley into the massed ranks of their foe.  Dick saw horses fall while others dashed away riderless.  But the Southern line wavered only for a moment and then came on again with many shouts.  There were also dismounted men on either flank who knelt and maintained a heavy fire upon the defenders.
