Two indictments were framed against him: one for being a priest and a jesuit, and the other for disparaging Protestantism; on these he was found guilty of high treason, and ordered to die according to the law. To the gaoler of the prison, the sheriff brought express commands from the judge to load him with the heaviest irons in the Castle, and to lodge him in a small cell where he could not lie down. This occurred on the 26th of August, 1628, and he suffered death on the 28th of the same month. He was dragged on a hurdle from the Castle to the place of execution, having received absolution from a fellow prisoner, Mr. Southworth, in the Castle yard. He was bound on the hurdle, and for greater ignominy with his head to the horse’s tail. The gallows and boiling caldron were set up about a quarter of a mile distant from the Castle. The devotion and piety of this holy and zealous man were as remarkable as his constancy and fortitude,--graces which edified those who witnessed his sad end. He offered himself up as a sacrifice thrice: once upon his knees at the foot of the ladder, again on the ladder, which he kissed, and a third time just before the halter was fastened round his neck; and then prayed fervently, “O Sweet Jesus, I freely offer Thee my death, in satisfaction for my sins.” Then he was cast off, suffered to hang until he was dead--an act of mercy, by no means ordinary or common--cut down, disembowelled, and quartered; his head being placed on a pole amongst the pinnacles of the Castle. It is recorded that the judge being vexed and annoyed with the clever and luminous answers which Arrowsmith made when under examination, in the hearing of so many, appeared to take a special pleasure in viewing the execution from his lodgings, through a perspective glass; that he had the curiosity to examine the four quarters of his body, which, by his command, being brought to his apartment, he made an unnatural and shocking comparison between them and a haunch or two of venison with which he had that day been presented; and that he deliberately kicked the right hand of the body in contempt. On leaving the town he ordered the martyr’s head to be placed on a pole six yards higher than the pinnacles of the Castle.
