Two weeks after the King had raised his standard at Nottingham, Essex led his army north towards Northampton, picking up support along the way (including a detachment of Cambridgeshire cavalry raised and commanded by Oliver Cromwell).
La două săptămâni după ce regele și-a ridicat steagul la Nottingham, Essex și-a condus armata spre nord spre Northampton, primind sprijin de-a lungul drumului (inclusiv un detașament de cavalerie Cambridgeshire adunat și comandat de Oliver Cromwell).
