In the deplorable Wars of the Roses, between the Lancastrians and the Yorkists, which extended over thirty years from 1455 to 1485, Derbyshire men took no small part, now on one side, now on the other, whilst occasionally they were found in the ranks of both parties. A commission issued in December, 1461, to Sir William Chaworth, Richard Willoughby, and the Sheriff of Derbyshire, illustrates the disturbed condition of the county in the beginning of the reign of Edward IV. These commissioners were ordered to arrest John Cokayne, of Ashbourne, who is represented as wandering about in various parts of the county with others, killing and spoiling the King’s subjects, and to bring him before the King in council. A manuscript list of the “names of the captayns and pety captayns wyth the bagges, in the standerds of the army and vantgard of the king’s lefftenant enterying into Fraunce the xvj day of June,” 1513, begins with George, Earl of Shrewsbury, the King’s lieutenant of the vanguard, who bore on his standard “goulles and sabull a talbot sylver passant and shaffrons gold”; the Derbyshire banneret, Sir Henry Sacheverell, with John Bradburne for his petty captain, bearing “goulles a gett buk sylver.” Other Derbyshire gentlemen who were captains in this array, each having his petty captain and his “bagges” (badges) or arms as borne on his standard, were:—Robert Barley with John Parker, Nicholas Fitzherbert with John Ireton, Sir John Leek with Thomas Leek his brother, Sir Thomas Cokayne with Robert Cokayne, Sir William Gresley with John Gresley, Sir Gylbert Talbot the younger with Humphrey Butler, Robert Lynaker with George Palmer, Thomas Twyford with Roger Rolleston, Sir John Zouch (of Codnor) with Dave Zouch (his brother), Arthur Eyre with Thomas Eyre (his brother), Ralph Leach and John Curzon (of Croxall) with Edward Cumberford. In addition to all these Derbyshire gentlemen, William Vernon bore the banner of St. George, John Leach the banner of the lieutenant’s arms, and Thomas Rolleston the standard of the talbot and chevrons. Derbyshire considerably preponderated in this army of the vanguard, there being twelve companies from that county. Shropshire had nine companies, Staffordshire eight, Nottinghamshire six, and Leicestershire and Cheshire two each; five other counties only furnished a single company.
