Thus once more Lancashire was brought into the general course of events. It was feared that Charles would try to break through to join the Earl of Montrose in Scotland; instead of advancing Leven retreated, notwithstanding remonstrances from Sir Thomas Fairfax. The Fairfaxes themselves were at York, and thus Lancashire was left completely undefended. The leaders were in great consternation. Already in the middle of March, 1645, it was feared that the King would march on Shropshire and Cheshire, and the Committee of Both Kingdoms wrote to Sir George Booth to be careful to guard Warrington.[166] Two months later the danger was acute; if the King could enter Lancashire he might indefinitely increase his forces. Charles penetrated into Cheshire in May, and obliged Sir William Brereton to raise the siege of Chester and draw his men into garrisons. Fairfax promised to send 1,500 men in order to hinder the King's advance, and the Lancashire leaders were urged to keep careful watch over all the passes into that county, and to have 200 horse and 1,000 foot ready to send to any rendezvous which Fairfax and Leven might appoint. Colonel Assheton's regiment was recalled in haste from Cheshire. The ford at Hale was guarded by 1,100 foot and 4 troops of horse, and the general rendezvous was appointed at Barlow Moor, near Manchester, on Thursday, May 19th. The Lancashire troops, however, attended in small numbers. They were greatly disorganised and the county much wasted by three years of war; and they complained of the place chosen for the rendezvous as being too near to plague-stricken Manchester. Lathom was still a thorn in the side of the Parliamentarians of the county, and they were obliged to leave some troops at Ormskirk to continue the siege; there remained only one company of foot to defend both Liverpool and Warrington, and one of Egerton's regiments flatly refused his order to march. On May 22nd the Lancashire Committee wrote to London that they had obeyed the orders regarding the disposition of troops, "but it is more difficult to defend the country near Manchester, the river being shallow, and the Scots and Cromwell both marching further off than was expected." Next day Sir William Brereton wrote from Manchester, giving a very gloomy picture of affairs. "The forces assigned for the passes are inconsiderable, the passes many and indefensible." All the men he could spare were on the borders of Cheshire but they were quite inadequate to oppose the King if he should try to enter Lancashire. A few days before the Earl of Callander had sent a letter to the Scotch Commissioners in London to the same effect. "If we should abandon Yorkshire to go into Lancashire, this county would lie open to the King, and York will probably be lost; if we stay here the King is at liberty to enter Lancashire and increase his army, because of the many disaffected persons in that county. It is impossible to defend both places which is a line of 80 miles, at once,
