The French spy Florence Hensey was due to die at Tyburn on this date in 1758. As it happened, the only violence done there was to the spectators.
A well-traveled Irish Catholic, Hensey had a prosperous London medical practice when he made an offer to a former colleague in France to share intelligence on war preparations at the outset of the England-vs.-France Seven Years’ War (1756-1763).
Upon being accepted into the ranks of salaried moles, Hensey set his industry to forming acquaintances at establishments where parliamentarians and their clerks met and gossiped, transmitting the resulting nuggets to France by way of Germany in lemon juice ink concealed within letters bearing nothing but everyday pleasantries. Eventually clerks suspicious at the volume of such superficially trivial exchanges being imposed upon the international post got nosy and found out the real story.
Hensey’s treachery was obvious, ongoing, and in the midst of wartime. He should have died for it, but on that very morning he was spared that miserable fate. The Newgate calendar professes “much surprise at the extension of royal mercy” considering numerous other precedents to the contrary.
De la Motte, the particulars of whose case we shall hereafter give, was “hanged, drawn, and quartered,” for the same kind of offence which Hensey committed; and in still more recent times, numbers have suffered death for similar treason; and yet we have to observe, without finding any especial reason for it, that Doctor Hensey was pardoned. If granted from political motives, it must have been in fear of Spain; an unworthy impulse of the ministers of a far greater and more powerful nation.
Indeed, the Spanish connection appears to be the best explanation for Hensey’s unexpected reprieve: he had a brother in the retinue of a Spanish ambassador who was able to exercise his empire’s diplomatic channels in the doctor’s service. (Spain was on the sidelines at this moment, and Britain keen to keep her there; the Spanish finally joined the war on France’s side very late in the game, in 1762.)
This gambit, however, came as quite a nasty surprise to the ample and bloodthirsty crowd that had turned up at Tyburn.
The awful procession to Tyburn, intended to impress the multitude with sentiments of reverence for the laws of their country, produced a very contrary effect; and the eager and detestable curiosity of the populace, to witness executions, became a source of considerable emolument to certain miscreants, who were in the habit of erecting scaffolds for spectators; many of these scaffolds were substantial wooden buildings, and erected at every point from whence a glimpse of the execution could be obtained; the prices for seats varied according to the turpitude or quality of the criminal: — Dr. Hensey was to have been executed for High Treason in 1758, the prices of seats for that exhibition amounted to 2s. and 2s. 6d.; but, in the midst of general expectation, the Doctor was most provokingly reprieved.
As the mob descended from their stations with unwilling steps, it occurred to them, that, as they had been deprived of the intended entertainment, the proprietors of the seats ought to return the admission-money; which they demanded in terms vociferous, and with blows offensive, and in short, exercised their happy talent for rioting with unbounded success. On this occasion a vast number of these erections were destroyed.
Hensey spent a couple more years in Newgate, then was released into obscurity; presumably he left the realm to his brother’s custody.
