The Post Robbing Story
1690, Aug 16
Andrew Cockhurn, the post-boy who carried the packet or letter-bag on that part
of the great line of communication which lies between Cockburnspath and
Haddington, had this day reached a point in his journey between the Alms-house
and Hedderwick Muir, when he was assailed by two gentlemen in masks; one of them
mounted on a blue-gray horse, wearing a stone-gray coat with brown silk
buttons;’ the other ‘riding on a white horse, having a white English gray cloak
coat with wrought silver thread buttons.’ Holding pistols to his breast, they
threatened to kill him if he did not instantly deliver up ‘the packet, black
box, and by-bag’ which he carried; and he had no choice but to yield. They then
bound him, and, leaving him tied by the foot to his horse, rode off with their
spoil to Gariton House near Haddington.
As the packet contained government communications besides the correspondence of private individuals, this was a crime of a very high nature, albeit we may well believe it was committed on political impulse only. Suspicion seems immediately to have alighted on James Seton, youngest son of the Viscount of Kingston, and John Seton, brother of Sir George Seton of Gariton (Garleton); and Sir Robert Sinclair, the sheriff of the county, immediately sought for these young gentlemen at their father’s and brother’s houses, but found them not. With great hardihood, they came to Sir Robert’s house next morning, to inquire as innocent men why they were searched for; when Sir Robert, after a short examination in presence of the post-boy, saw fit to have them disarmed and sent off to Haddington. It was Sunday, and Bailie Lauder, to whose house they came with their escort, was about to go to church. If the worthy bailie is to be believed, he thought their going to the sheriff’s a great presumption of their innocence. He admitted, too, that Lord Kingston had come and spoken to him that morning. Anyhow, he concluded that it might be enough in the meantime if he afforded them a room in his house, secured their horses in his stable, and left them under charge of two of the town-officers. Unluckily, however, he required the town-officers, as usual, to walk before him and his brother-magistrates to church; which, it is obvious, interfered very considerably with their efficiency as a guard over the two gentlemen. While things were in this posture, Messrs Seton took the prudent course of making their escape. As soon as the bailie heard of it, he left church, and took horse after them with some neighbours, but he did not succeed in overtaking them.
The Privy Council had an extraordinary meeting, to take measures regarding this affair, and their first step was to order Bailie Lauder and the two town-officers into the Tolbooth of Edinburgh as close prisoners. A few days afterwards, the magistrate was condemned by the Council as guilty of plain fraud and connivance, and declared incapable of any public employment. William Kaim, the smith at Lord Kingston’s house of Whittinghame, was also in custody on some suspicion of a concern in this business; but he and the town-officers were quickly liberated.’
John Seton was soon after seized by Captain James Denholm on board a merchant-vessel bound for Holland, and imprisoned in the Castle of Edinburgh. He underwent trial in July 1691, and by some means escaped condemnation. A favourable verdict did not procure his immediate liberation; but, after three days, he was dismissed on caution to return into custody if called upon. This final result was the more remarkable, as his father was by that time under charge of having aided in the betrayal of the Bass.
