For a man who was to become one of the leading merchants of the staple of Calais, Prout’s background is surprisingly obscure. Although it is not known whether he was a native of Berkshire, by the early 1440s he was living at Streatley on the Thames below Wallingford, and possessed property there which may have come to him by marriage to the daughter of a local landowner. His wife was buried in the parish church of St. Mary.
Where Prout served his apprenticeship is uncertain, and few details survive about his early trading activities or when he began to ship wool through the port of London.
The overwhelming problems of the financing of Calais and its garrisons were not to be properly addressed until the following year, when, in April 1454 towards the close of the Parliament, the duke of York, as Protector, reached an agreement with the staplers to renew assignments totaling some 12,000 marks in repayment of long outstanding loans, and to reverse bills introduced earlier in the parliamentary session which were prejudicial to the company’s interests, in return for an advance of 10,000 marks from the company for the wages of the garrisons at Calais. In October warrants were sent out to revenue collectors authorizing the repayment of these most recent loans, which included one of £65 made by Prout. What part he had taken in any debates in the Commons on this matter went unrecorded.
Following his service in the Commons for Reading, Prout was shortlisted for appointment as the town’s mayor on 24 Sept. 1456, only to be passed over for selection by its lord the abbot. He never came to occupy the post.
Yet the staplers themselves were not all in accord. In the course of 1460 one of them, Richard Heyron (an associate of the Lancastrian treasurer the earl of Wiltshire), made serious allegations against his fellows, including Prout (in his capacity as lieutenant to the mayor of the staple, John Thirsk*), John Walden* (mayor sometime that year), John Tate† and others, accusing them of unjustly placing an embargo on the sale of his wool, amounting in value to 13,000 marks, by commanding all brokers, weighers, ‘potters’, treasurers and clerks of the staple not to deal with it. It appears from the depositions Heyron subsequently made in the parlement at Paris (in July 1461) that in 1459-60 he was imprisoned at Calais for nine months before escaping to Bruges where he brought an action against three of the staplers for the recovery of his merchandise, and had appealed to the parlement after the council of the duke of Burgundy had rejected his suit. Meanwhile, in late 1460 the case had been brought before the lords of Henry VI’s Council. The matter long remained unresolved, and had to be considered again, notably by the Council of Edward IV in March 1463.
Prout served as mayor of the staple at Calais (and ex officio victualler there),
Prout was styled ‘esquire’ at his election to Parliament for Reading on 2 Oct. 1472,
Little else is known about Prout. Surprisingly, he was recorded as a feoffee of lands at Metton and Antyngham in Norfolk, on behalf of one Simon Fynche, an undertaking which involved him in litigation in Chancery, probably in the 1450s, when Fynche’s grandson and heir alleged that he had unjustly refused to deliver seisin to him.
Whether John left surviving children is uncertain. His putative son Thomas had become a member of Edward IV’s household in the 1460s, rose to be an esquire for the body,
