Cromwell meanwhile, had reached the River Tyne in seven days, and thence, marching a day in extreme heat with the country people carrying their arms and equipment the regulars entered Ferrybridge on 19 August, at which date Lambert, Harrison and the north-western militia were about Congleton. It seemed probable that a great battle would take place between Lichfield and Coventry on or just after 25 August, and that Cromwell, Harrison, Lambert and Fleetwood would all take part in it. But shortly after leaving Warrington Charles resolved to abandon the direct march on London and to make for the Severn valley, where his father had found numerous adherents, and which had been the centre of gravity of the English Royalist movement of 1648. However, Charles's army was perceived as a Scottish invasion, and popular sentiment was against it. Charles arrived at Worcester on 22 August, and spent five days resting the troops, and gathering and arming the few recruits who came in.
