This was a severe blow; and all hopes of acting according to the earl's plan of establishing himself strongly in Argyleshire were now extinguished. He therefore consented to pass the Leven, a little above Dumbarton, and to march eastwards. In this march he was overtaken, at a place called Killerne, by Lord Dumbarton, at the head of a large body of the king's troops; but he posted himself with so much skill and judgment, that Dumbarton thought it prudent to wait, at least, till the ensuing morning, before he made his attack. Here, again Argyle was for risking an engagement, and in his nearly desperate situation, it was probably his best chance, but his advice (for his repeated misfortunes had scarcely left him the shadow of command) was rejected. On the other hand, a proposal was made to him, the most absurd, as it should seem, that was ever suggested in similar circumstances, to pass the enemy in the night, and thus exposing his rear, to subject himself to the danger of being surrounded, for the sake of advancing he knew not whither, or for what purpose. To this he could not consent; and it was at last agreed to deceive the enemies by lighting fires, and to decamp in the night towards Glasgow. The first part of this plan was executed with success, and the army went off unperceived by the enemy; but in their night march they were misled by the ignorance or the treachery of their guides and fell into difficulties which would have caused some disorder among the most regular and best-disciplined troops. In this case such disorder was fatal, and produced, as among men circumstanced as Argyle's were, it necessarily must, an almost general dispersion. Wandering among bogs and morasses, disheartened by fatigue, terrified by rumours of an approaching enemy, the darkness of the night aggravating at once every real distress, and adding terror to every vain alarm; in this situation, when even the bravest and the best (for according to one account Rumbold himself was missing for a time) were not able to find their leaders, nor the corps to which they respectively belonged; it is no wonder that many took this opportunity to abandon a cause now become desperate, and to effect individually that escape which, as a body, they had no longer any hopes to accomplish.
