A group of disaffected knights decided to revenge themselves on the Earl of Lancaster by attacking his chief retainer and their rival, Sir Robert de Holland.
The cause of their grievance was that the powerful earl, the dominant force in the north-west of England, appeared to be favouring the Holland family to their disadvantage.
That day the group raided the farm of the bailiff of the Rector of Wigan, another Holland supporter, stealing crops and other goods.
[2][3] Eventually Edmund de Neville, the Deputy Sheriff of Lancashire, organised a force loyal to the earl and confronted the rebels at Deepdale in Preston.
After Edward was overthrown in 1326, Sir Robert de Holland was released, only to be killed in 1328 by the new Earl of Lancaster's men for his treachery at Boroughbridge.
