About the middle of the summer, however, she ventured to a place called Swaddling Bar to drink the mineral waters there for her health; but even thither this unhappy man followed her, and he was seen in a beggar's habit dogging her footsteps. Thus disguised he was detected; and when warned never to appear there again, he swore, in the presence of several, that he would murder the whole family if he did not get possession of his wife--a threat which he subsequently attempted to carry out. Notwithstanding his violence, it appears that he was permitted again to escape to London; and he remained there until the month of October in the same year. At the beginning of November he was again seen in Ireland; and having approached the residence of the Knoxes, he was known to sleep with three of his accomplices, at the house of a hearth-money collector, very nearly adjoining the abode of his intended victim. The 10th was the day fixed upon by him for the attack; and on that morning M'Naughton, with his companions, went to a cabin on the road-side with a sack full of fire arms, in order to await the passing of Mr. Knox's coach, in which it was known the family were about to proceed to Dublin. One of the men was despatched to ascertain the moment of the coming of the vehicle; and when it appeared in sight, having obtained the information requisite for its identification, he hurried back to desire the projector of the scheme to prepare. It appears that the only persons in the carriage were Mr. Knox and his wife, their daughter and a maid-servant; and they were attended only by one livery-servant, and a faithful fellow, a smith, who was foster-father to Miss Knox, and whom no bribe could ever purchase, although most of the other servants had been tampered with. As soon as the coach came near the cabin, two of the villains, armed with guns, presented themselves to the postilion and coachman, and stopped the horses, while M'Naughton fired at the smith with a blunderbuss. The latter escaped being wounded, and presented his piece in return, but it unfortunately missed fire, and M'Naughton and one of his companions seizing the opportunity, again fired, and both of them wounded him. Mr. Knox at this time drew up the blinds of the carriage, and M'Naughton observing this, ran round to the other side, and firing in at the window obliquely, with a gun loaded with five balls, shot Miss Knox, all the balls taking effect in her body. The maid-servant now let down the window, screaming that her mistress was murdered; and the livery-servant on hearing this came from behind a peat-stack, where he had concealed himself for safety, and firing at M'Naughton, wounded him in the back; and about the same time Mr. Knox from the coach discharged a pistol, which was the last of eight shots fired on this strange and dreadful occasion.
