James Caulfield: "Portraits, memoirs, and characters, of remarkable persons, from the revolution in 1688 to the end of the reign of George II. Collected from the most authentic accounts extant" :
"William Tunstall was one of the northern gentlemen who espoused the Stuart interest in opposition to George the First, on his first coming to the throne of England ; and when the rebellion broke out in 1715, he joined the Pretender's standard. His residence was in the north of England, where his family had flourished many centuries, in credit and esteem. This gentleman was taken prisoner at Preston, and conducted, with many others, to London ; they suffered no great indignity or insult on the road, until their arrival at Highgate, where they were met by Major-general Tutton, with two battalions of the royal foot-guards completely armed, who being provided with cords sufficient to pinion each of them, after the manner of condemned criminals, and to lead their horses with (since, from the lord to the footman, they were to have each a grenadier for that purpose ;) in this array and order they entered the metropolis, and were conducted to the several prisons appointed for their reception ; the division appointed to take up their abode in the Tower went two by two, at the head of which were the Earls of Derwentwater and Widdrington, the other lords and noblemen following with haltered horses, and their riders, like common malefactors.
A great number in like manner were conveyed to Newgate, and others, among whom was Mr. Tunstall, were safely lodged in the Marshalsea-prison.
On the 25th of April, 1716, Mr. Tunstall, together with Mr. Tildesley, Mr. Dalton, Mr. Townley, Mr. Hodoreson, the two Mr. Heskeths, Mr. Walton, and Mr. Leibourne, were arraigned at the Marshal-sea, upon the bills of indictment of high-treason found against them, and severally pleaded not guilty. On the 30th of May following Mr. Tunstall, being brought to the bar, withdrew his former plea, and pleaded guilty to his indictment. On the 26th of June, he was again placed at the bar, and sentence of death was passed upon him ; after which, he lay in prison unconscious of his fate ; yet numbers, implicated in the same unfortunate situation, were almost daily led to execution. On the 22d of April, 1717, Mr. Dalziel, Mr. Carnegie, and Mr. Tunstall, Preston prisoners under sentence of death, were removed , the two first from Newgate, and the last from the Marshalsea, into the custody of messengers, and shortly after pleaded to a free pardon."
