Sir William Assheton had an unusual career, played out not only in his native Lancashire but in France and, for a brief but important period in its latter part, in East Anglia. His family may have been a junior branch of the Asshetons of Ashton-under-Lyme, one of the leading gentry families of Lancashire, although the heraldic evidence is against such an identification.
At the time of his father’s death William must have been a minor. Since the manor of Croston was held of the wealthy Lancastrian knight, Sir Robert Neville† of Hornby (Lancashire), he may have come into that knight’s wardship, yet the survival of his mother, the heiress to these lands, probably meant either that he did not or else did not do so immediately. She was alive in 1409 but, if she did die soon afterwards, it is possible that Sir Robert was responsible for his first marriage to an unknown bride. However this may be, our MP seems to have been of age by 8 May 1412 when he made a lease of property at Mawdesley to a wheelwright named Thomas Rotour.
No record survives of Assheton’s service on the 1417 campaign, but in February 1420 he enlisted again for war service.
Assheton returned with Henry V to England in February 1421 and, in the first evidence of his involvement in domestic affairs, he then took a prominent part in the Lancashire election of 2 Apr. to the Parliament summoned to meet on 2 May. Not only did he head the attestors but the election was convened, not, as was generally the case, at Lancaster, but at Croston. The return of his son’s father-in-law Urswyk additionally implies that he had a particular interest in the identity of the elected, with the election’s other dynamic involving the sheriff Sir Richard Radcliffe, whose son, Sir Thomas*, was the other man elected.
There is no further record of Assheton’s service in France for the remainder of the 1420s, but his lack of much recorded activity in Lancashire implies that he remained intermittently involved in the French war throughout that decade as he was certainly to be in the 1430s. He did, however, find time in about 1425 to contract in the Yorkshire church of Giggleswick what proved to be an ill-advised second marriage.
In the early 1430s Assheton’s career briefly prospered. On 7 Apr. 1432 he was elected to Parliament by a high-ranking group of attestors, headed by five of the county’s knights (including, in Sir William Haryngton and Pilkington, two of those who had earlier offered surety for Shirburne). He made good use of his time at Westminster. On 5 June, in the midst of the parliamentary session, he secured a grant from the duchy of Lancaster feoffees of the stewardship and master-forestership of Bowland in north-east Lancashire.
Domestic difficulties provided Assheton with another cause for discontent. On 6 Sept. 1434 his second wife secured an ecclesiastical commission, seeking a divorce on the grounds that her husband had been pre-contracted to one Joan Brackley. Their divorce was eventually proclaimed in the church of Warrington on 16 July 1438.
The story of the pre-contract provides further evidence of Assheton’s connexion with the Mowbrays. He is said to have contracted the promise of marriage with Joan in the summer of 1422 at a hospitium called ‘le Brokyn Wharff’, a Mowbray property in London.
While his divorce proceedings were pending, Assheton embarked on another military adventure. Early in 1436 he was one of six knights who undertook to serve in an army of 2,000 to be led by Edmund Beaufort, count of Mortain, on a campaign in Anjou and Maine. The Burgundian threat to Calais, however, led to the expedition’s diversion to the defence of that town, where it arrived soon after Easter. According to a celebratory contemporary account of the siege’s failure, the expedition’s leaders, of whom our MP was named as one, distinguished themselves in a series of raids into Burgundian territory that impeded the laying of the siege. A contemporary poem, ‘On the Siege of Calais’, praises Assheton and another of Mortain’s captains, Sir Geoffrey Warburton, as responsible for guarding the Milkgate and setting the watch during the siege itself.
In the 1440s Assheton, now apparently permanently returned to England, became involved in two disputes. The one involved the sort of contradictory grant that was not uncommon under the majority government of Henry VI. On 13 July 1444 the Crown, disregarding the earlier grant to our MP, farmed the manor of Littlewood to another soldier, Sir Bertrand Entwhistle, from the following Michaelmas on the same terms as it was held by Assheton. Understandably he resisted his removal. His farm of Littlewood, even leaving aside any financial advantage it may have had, was an important one for him as he had established a residence there.
The legal difficulties occasioned for Assheton by another dispute – a violent clash with his neighbour Sir Richard Radcliffe of Smithills – provide another reason for the view that he was deprived of his farm of Littlewood in the late 1440s. On 5 Nov. 1446 his eldest son, Thomas, and a group of Assheton servants, including our MP’s old tenant, Thomas Rotour, besieged Radcliffe’s mansum at Eccleston and assaulted him; on the following day, presumably in connexion with the same dispute, Sir William himself allegedly collected 100 malefactors at his house at Ulnes Walton; and a day later he and his men assaulted one of Radcliffe’s servants, John Draper, at Eccleston.
Yet for Assheton this was not the end of his troubles. At the Lent assizes of 1448, that is, about a month before his appearance before the duchy council, he pleaded not guilty and was committed for a trial.
The next significant reference to Assheton is a striking and unexpected one. According to indictments laid before royal justices at Ipswich on 17 Feb. 1453, he and Hugh Assheton were among those, including the duke of York’s chamberlain, Sir William Oldhall*, guilty of various acts of treason in the spring and early summer of 1450. Our MP was said to have conspired with other traitors at Bury St. Edmunds on 6 Mar. 1450 to depose the King in favour of the duke of York and to have disseminated treasonable ballads to foment rebellion in Sussex and Surrey; on 12 Apr. he was one of those who had proclaimed the rebel Jack Cade their leader and then gone to Blackheath with other rebels; on 26 May he and others sent letters from Bury urging the men of Kent to rebel; and, finally, on 10 June he was among those who made insurrection at East Bergholt and other places in Suffolk. These charges were, very probably, fabrications, but Assheton’s inclusion among the indicted throws an interesting light upon his career. In the indictments he is described as resident at Earl Soham, a Suffolk manor of the duke of Norfolk, and Hugh Assheton as living at the Mowbray castle of Framlingham. Clearly they were indicted, just like others of those charged, as Mowbray servants. The indicting jury, headed by (Sir) Miles Stapleton*, Gilbert Debenham I*, Edward Grimston and John Ulveston*, was hostile to duke and anxious to discredit him and his followers. Little value can thus be placed on the detail of the indictments.
Assheton’s service to Mowbray was to have another manifestation at the Suffolk election of 1453. According to the complaint of the sheriff of Norfolk and Suffolk, Thomas Sharneburne*, our MP and other of the duke’s leading men had violently subverted the election, intimidating his under sheriff and his clerk, bringing 600 men (among whom were at least three of Assheton’s own intimates, that is, Nicholas and Laurence Millington, kinsmen of his third wife, and Hugh Assheton) to the county court on election day (12 Feb.) and forcing the unlawful election of Thomas Daniell* and John Wingfield†. Since this election was held only five days before the more serious charges were laid against our MP by a jury that Sharneburne himself had empanelled, it is not improbable that the two events were linked, with the treason indictments intended to deter the violence of Assheton and other of the duke’s men. However this may be, neither the indictments nor Sharneburne’s accusations about the election occasioned Assheton any long-term difficulty. In Hilary term 1455 he personally appeared in King’s bench to have the latter dismissed on a technicality.
Whether Assheton then went on to fight a month later at the first battle of St. Albans (where Entwhistle met his death ex parte Regis) must be doubtful. His place in Norfolk’s retinue was the only reason for his presence, and the duke, according to the best source, did not arrive at the site of the battle until the day after it was fought.
Little is known of the last years of Assheton’s long career. His support for the Yorkist cause appears to have continued through the agency of his eldest son. On 20 Dec. 1459 Thomas had a pardon for treasons enrolled on the patent roll, and it is a fair inference that he had been in the Yorkist ranks at the battle of Blore Heath and perhaps also at the rout at Ludford Bridge. Sir William’s own requirement for a pardon was much less pressing. On 12 Oct. 1460, when the Yorkists were in control of government, he sued out a routine one for a minor outlawry for debt.
