This request being made known to the Earl of Sandwich, then first lord of the admiralty, that nobleman directed Sir John Fielding to send down proper persons to take and attest his confession.
He said that the diabolical scheme of setting fire to the dock-yards and the shipping originated in his own wicked mind, on the very breaking out of the rebellion in America; and he had no peace until he proceeded to put it in practice. The more he thought of it, the more practicable it appeared; and with this wicked intent he crossed the Atlantic. He had no sooner landed than he proceeded to take surveys of the different dock-yards; and he then went to Paris, and had several conferences with Silas Deane, the rebel minister to the court of France. Deane was astonished at Hill’s proposals, which embraced the destruction of the English dock-yards and the shipping; but finding the projector an enthusiast in the cause of America, and a man of daring spirit, he gradually listened to his schemes, and supplied him with money to enable him to carry them into execution, procured him a French passport, and gave him a letter of credit on a merchant in London. He then confirmed the evidence given against him, and in particular that of the witness Baldwin; and he added, that had he been successful in his attempt upon Portsmouth and Plymouth dock-yards, he should have been rewarded with a commission in the American navy.
FRANCIS MERCIER, alias LOUIS DE BUTTE.
EXECUTED FOR MURDER.
THE case of this criminal was attended by circumstances of very great atrocity. The malefactor and his unfortunate victim were natives of France.
The unfortunate Jacques Mondroyte was a jeweller and watchmaker of Paris, and had made a journey to London, in order to find a market for different articles of his manufacture. His stock consisted of curious and costly trinkets, worth, as was computed, a few thousand pounds. He took lodgings in Prince’s-street, and engaged Mercier, who had resided some time in London, as his interpreter, on a liberal gratuity, and treated him as a friend.
It appeared that the ungrateful villain had long determined upon murdering his employer, in order to possess himself of the whole of his valuable property. To this diabolical end, he gave orders for an instrument to be made of a singular construction, which was a principal means of leading to his discovery as the murderer. It was shaped somewhat like an Indian tomahawk; and this instrument of death he concealed until an opportunity offered to effect his detestable purpose.
One day, his employer, Monsieur Mondroyte, invited him to spend the evening: they played at cards, sang some French songs, and took a cheerful glass, but with that moderation peculiarly observable among Frenchmen; and a late hour having arrived, the kind heart of the host forbade his dismissing his friend without offering him a bed for the night. The offer was accepted after some hesitation, and both parties retired to rest. As soon as the neighbours were wrapped in sleep, Mercier took from the lining of his coat, where it had remained constantly concealed, the fatal weapon which had been prepared, and with it he struck his victim repeated blows on the head until he killed him. He then thrust the body into one of the trunks in which the owner had brought over his merchandise, and having ransacked and plundered the apartments, he locked the doors and made his escape.
On the next day he had the hardihood to return to the house, and to inquire whether Monsieur Mondroyte had set off, pretending that he had proposed a journey into the country; and the people of the house concluding that he had let himself out before they had risen, and that this accounted for their finding the street door on the latch, replied that he must have departed, giving that circumstance as a reason for such belief. This audacious farce was acted by the murderer for some days, during which time he frequently called to know whether his friend had returned. The family, however, beginning to entertain suspicions of some foul play, procured a ladder, entered the chamber window of their unfortunate lodger, and soon discovered the body crammed into the trunk, which was only two feet four inches long, already beginning to putrefy. There appeared on the head several deep wounds.
A warrant was thereupon granted to apprehend Mercier, who was taken just as he was alighting from a post-chaise, in which he had been jaunting with a woman of the town. In his lodgings, and on his person, were found sixteen gold watches, some of great value; a great number of brilliant diamond and other rings; a variety of gold trinkets; and seventy-five guineas.
