From the escape of Lord Cobham, or perhaps from the extraordinary affair of St. Giles' Field, which must now engage our attention, we perceive a most evident change in the sentiments and conduct of King Henry towards the Lollards, and especially towards Lord Cobham. Up to that time he seems to have considered their only crime to have been heresy, and he anxiously employed his good offices to rescue and save them: after that time he appears to have regarded them as his own personal enemies, subverters of order, traitors to the throne and the kingdom; and their heresy and schism were identified in his mind (p. 377) with the crimes of sedition and treason.[288] How far this view of their principles and designs was just, has been disputed. Both sides of the question have been strongly maintained. The inquiry is by no means devoid of interest in itself; and, as far as Henry's conduct and character are involved in the transactions of that time, is indispensable; and throughout the inquiry it must be remembered that the elucidation of his character, not the acquittal or conviction (p. 378) of Oldcastle and the Lollards, is the object we have in view. [Footnote 288: Soon after the affair of St. Giles' Field much pains seem to have been taken to discover the retreat of Cobham. The Pell Rolls, February 19, 1414, record payments to constables and others for their careful watch and endeavours to take him; and "chiefly for having found and seized certain books of the Lollards in the house of a parchment-maker;" and one hundred shillings as an especial reward "for the great pains and diligence exercised by Thomas Burton, (the King's spy,) for his attentive watchfulness to the operations of the Lollards now _lately rebellious_; also because he fully certified _their intentions_ to the King for his advantage." This document (for ignorance of which no former historian may deserve blame, though its existence should caution every one against drawing hasty conclusions from negative evidence,) proves that at the Exchequer the Lollards were considered as having been lately rebellious, and as having had designs against the King. In a deed too, signed and sealed by the tenants of Lord Powis, who themselves took Lord Cobham, both heresy and treason are specified as the crimes of which he had been convicted "that was miscreant and unbuxom to the law of God, and _traitor convict_ to our most gracious sovereign and his."
