The rebels had first mustered under Booth at
Warrington on 1 August. Booth's rising was part of a larger national conspiracy, led by
John Mordaunt, 1st Viscount Mordaunt, to return the exiled
Charles II by taking advantage of ongoing political instability in the
Commonwealth of England. While the national rising was quickly suppressed, Booth had local success, seizing the city of
Chester and attracting 3-4,000 followers.
Liverpool and parts of north-east Wales also declared for the rebels. ; Lambert attempted to intercept Booth's rebels here the day before confronting them at Winnington Bridge Booth initially began marching towards
Manchester, but quickly realised that he was isolated, and turned back after receiving reports that government forces under General
John Lambert were en route to confront him. While Booth had been a Parliamentarian colonel in the
First English Civil War, he was unsure how to respond; he opened negotiations with Lambert, while simultaneously attempting to withdraw to the relative safety of Chester. Lambert had left London on 6 August, following two infantry regiments that had set out the previous day. By 10th he had reached
Coventry; on 14th the infantry rendezvoused with cavalry forces at
Market Drayton in Shropshire. By 15th Lambert and the main army were at
Nantwich; a force under
Robert Lilburne was marching on Cheshire from the north, while Parliament had ordered a 1,500-strong brigade under
Sankey to sail from
Dublin to
Beaumaris and secure the rebel districts' western flank. Lambert was making directly for Chester, but on receiving information that Booth and a force estimated at 4-5,000 were near
Northwich, advanced to cut off the rebels in the area of
Delamere Forest. Lambert's rapid advance took the rebels by surprise and only a retreat ordered by
Roger Whitley saved them from being overrun. On the evening of 18 August Lambert's scouts made contact with Booth's rearguard in Delamere Forest, but as darkness fell the two armies went into quarters, Lambert in
Weaverham and Booth a few miles to the east in Northwich. ==The battle==
