"Forward! march!" said the non-commissioned officer. "Huzza, my boys, for Rob Roy's head and a purse of gold." He quickened his pace into a run, followed by the six soldiers; but as they attained the first traverse of the ascent, the flash of a dozen of firelocks from various parts of the pass parted in quick succession and deliberate aim. The sergeant, shot through the body, still struggled to gain the ascent, raised himself by his hands to clamber up the face of the rock, but relaxed his grasp, after a desperate effort, and falling, rolled from the face of the cliff into the deep lake, where he perished. Of the soldiers, three fell, slain or disabled; the others retreated on their main body, all more or less wounded. "Grenadiers, to the front!" said Captain Thornton.--You are to recollect, that in those days this description of soldiers actually carried that destructive species of firework from which they derive their name. The four grenadiers moved to the front accordingly. The officer commanded the rest of the party to be ready to support them, and only saying to us, "Look to your safety, gentlemen," gave, in rapid succession, the word to the grenadiers--"Open your pouches--handle your grenades--blow your matches--fall on." The whole advanced with a shout, headed by Captain Thornton,--the grenadiers preparing to throw their grenades among the bushes where the ambuscade lay, and the musketeers to support them by an instant and close assault. Dougal, forgotten in the scuffle, wisely crept into the thicket which overhung that part of the road where we had first halted, which he ascended with the activity of a wild cat. I followed his example, instinctively recollecting that the fire of the Highlanders would sweep the open track. I clambered until out of breath; for a continued spattering fire, in which every shot was multiplied by a thousand echoes, the hissing of the kindled fusees of the grenades, and the successive explosion of those missiles, mingled with the huzzas of the soldiers, and the yells and cries of their Highland antagonists, formed a contrast which added--I do not shame to own it--wings to my desire to reach a place of safety. The difficulties of the ascent soon increased so much, that I despaired of reaching Dougal, who seemed to swing himself from rock to rock, and stump to stump, with the facility of a squirrel, and I turned down my eyes to see what had become of my other companions. Both were brought to a very awkward standstill.
