The effect of this respite on the minds of the people of Scotland was to induce the belief that the government did not intend to carry out the sentence of death against Porteous at all--that it was merely a preliminary step to his pardon and liberation--and that, so far from condemning him, the government had rather taken up a prejudice against the town of Edinburgh, on account of the proceedings, and in some measure against all Scotland. A number of persons, therefore, who were never discovered, resolved to take the matter into their own hands, and on the 7th of September 1736, a body of strangers, supposed to be from the counties of Fife, Stirling, Perth, and Dumfries, many of them landed gentlemen, entered the West Port of Edinburgh between nine and ten o'clock at night, and having seized the Portsburgh drummer by the way, brought along his drum with them, and his son. Some of them advancing up into the Grassmarket, commanded the drummer's son to beat to arms. They then called out, "Here! all those who dare to avenge innocent blood!" This probably was a signal for their associates to fall in. It was followed by instantly shutting up the gates of the city, posting guards at each, and flying sentinels at all places where a surprise might be expected, while a separate detachment threw themselves upon and disarmed the city-guard; and seizing the drum, beat about the High Street to notify their success so far at least. At that instant, a body of them proceeded to the Tolbooth, called for the keeper, and finding he was gone, fell a-breaking the door with fore-hammers; but making no great progress in that way, they got together a parcel of dried broom, whins, with other combustibles, and heaps of timber, and a barrel of pitch, all previously provided for the purpose, and taking the flambeaux or torches from the city officers, they set fire to the pile. When the magistrates appeared, they repulsed them with showers of stones, and threatened, if they continued in the streets and offered resistance, they would discharge platoons of fire-arms among them; and it is even reported they placed sentinels on the magistrates to watch their motions. Upon the prison door taking fire, two gentlemen made up to the rioters, and remonstrated with them on the imminent danger of setting the whole neighbourhood on fire, insinuating that this outrage was likely to be deeply resented, and might bring them to trouble; to which it was answered that they should take care no damage should be done to the city, and that as to the rest, they knew their business, and that they (the gentlemen) might go about theirs.
