On the 25th, Lilburne received intelligence that the Earl of Derby was marching towards Wigan and assuming his force was retreating gave chase. However, it was Derby's intention to fall on Cromwell's regiment of infantry before Lilburne's cavalry could join it. When Lilburne reached Wigan he found the enemy in considerable force, both infantry and cavalry, marching out of the town towards Manchester. Having arrived ahead of his own infantry and the terrain surrounding the town consisting of fields and hedges with narrow country lanes unfavourable for cavalry, Lilburne determined to avoid a fight. He instead intended to await infantry reinforcements before flanking the Royalists in Wigan, sending his cavalry around the town to the south while his infantry advanced into the town from the north encircling and preventing Derbys retreat from the town.
