Hickes is a somewhat remarkable figure in post-office history. Sometime before the Restoration he was again employed in the Post Office in London; and in a petition addressed to the king in 1666, he describes the services rendered by him during the period above mentioned. In that memorial he says that he then "carried personally His Majesty's foreign letters and packets to Oxford, with the hazard of his life"; that "in the year 1643 he was committed to prison by Corbett the traitor, and in great danger of being tried for his life by the unjust laws then practised, for holding correspondence with Mr. Secretary Nicholas in His Majesty's service, and, having with much difficulty escaped to Oxford, he was employed in several expeditions and employments of trust, by both the then Principal Secretaries of State; and settled at Weymouth to manage two packet boats, for conveyance of His Majesty's despatches to and from foreign parts, as will appear by their several commissions, and under his said Majesty's royal hand and signet; during which time he exposed his wife and children to the charity of others, himself to daily dangers, and his small fortune to an utter diminution." "Corbett the traitor" referred to is no doubt one of the regicides afterwards taken in Holland, and who was hanged and quartered at Tyburn on the 19th April 1662. His full name was Miles Corbett. About the year 1644, Thomas Witherings must have been, or considered to be, a man of a respectable estate, for, according to the proceedings of the Committee for the Advance of Money, he was, on the 18th June of that year, assessed for a contribution of £800. Now, as the assessment was based upon one-twentieth of real estate, and one-fifth of personal estate, the sum assessed represents a condition of fair wealth. The full amounts of these assessments were seldom, however, exacted, and Witherings seems to have been let off after making payments amounting to about £550.
