this timeline to be important in determining authorship, as the original timeline would place Malory's birth in the early to mid 1390s. He would therefore have been at least 75 when Le Morte was completed, as he must have been at least in his late teens or early 20s at the time of his commission: his peers of the same rank in Dugdale's record were in their mid- to late-twenties. According to the alternate timeline, his birth would have been around 1415-1418 and his age when Le Morte was completed would have been a much more reasonable 55-58. William Matthews emphasizes the importance of Malory's age thus: "There is considerable evidence that the medieval view was that by sixty a man was bean fodder and forage, ready for nothing but death's pit... it might be best to find out how old the Warwickshire knight really was in 1469." Researching the question, Matthews made an original discovery: Sir William Dugdale’s surviving 15th century notes and papers in the Bodleian Library on the Agincourt campaign contain a lengthy military roster (apparently in Dugdale’s own hand) with the following detail: Because this original French note perfectly matches the English translation in Dugdale’s published work, and because a number of the other knights listed on the same commission roster are known to have died long before 1436, Matthews concludes that these commissions cannot refer to the 1436 campaign; and therefore Thomas Malory of Newbold Revel must have been commissioned into Henry V’s Agincourt campaign around 1414 or 1415, confirming Kittredge's original timeline and making this Malory in his mid-70s to early 80s at the time the book was completed. Matthews asserts, “seventy-five is no age at all to be writing Le Morte Darthur in prison.” Much more detail was added to Thomas Malory of Newbold Revel's biography by Edward Hicks in 1928, revealing that this Thomas Malory had been imprisoned as a thief, bandit, kidnapper, attempted murderer, and rapist; which hardly seemed in keeping with the high chivalric standards of his book. Helen Cooper referred to his life as one that "reads more like an account of exemplary thuggery than chivalry". Shortly before his death, C.S. Lewis stated that this issue was a grave one for readers of Le Morte D'arthur. E.K. Chambers emphasizes the importance of the problem by quoting the author himself: Modern English: Chambers comments, "Surely the Sir Thomas of Monks
