Meanwhile Warwick retired to Calais, where he called together the officers of the garrison, and the Mayor and aldermen, set forth to them the attempt upon his life, and begged them to be true to him and guard him against the machination of his enemies.
The next attack of the Queen on the followers of York was long in coming; nine months elapsed between the affray at Westminster and the final outbreak of Civil War.
Meanwhile [says the chronicler] the realm of England was out of all good governance, as it had been many days before; for the King was simple, and led by covetous counsel, and owed more than he was worth. His debts encreased daily, but payment was there none; for all the manors and lordships that pertained to the Crown the King had given away, so that he had almost nought to live on. And such impositions as were put on the people, as taxes, tallages, and 'fifteenths,' all were spent in vain, for the King held no household and maintained no wars. So for these misgovernances the hearts of the people were turned from them that had the land in governance, and their blessing was turned to cursing. The Queen and her affinity ruled the realm as they liked, gathering riches innumerable. The officers of the realm, and specially the Earl of Wiltshire, the Treasurer, for to enrich themselves pilled the poor people, and disherited rightful heirs, and did many wrongs. The Queen was sore defamed, and many said that he that was called the Prince was not the King's son, but gotten in adultery.
The name of Wiltshire, "the best-favoured knight in the land, and the most feared of losing his beauty," was united with that of Margaret by many tongues, and the Queen's behaviour was certainly curious; for instead of staying with her husband, she was continually absent from his side, busied in all manner of political intrigues, and only visiting King Henry when some grant or signature had to be wrung out of him. All the summer of 1459 she was in Lancashire and Cheshire "allying to her the knights and squires in those parts for to have their benevolence, and held open household among them, and made her son give a livery blazoned with a swan to all the gentlemen of the country, trusting through their strength to make her son King; for she was making privy means to some lords of England for to stir the King to resign the crown to his son; but she could not bring her purpose about."
The exact details of the outbreak of the war are hard to arrange chronologically. Writs were being sent about by the Queen in the King's name ordering every one to be ready to assemble "with as many men as they might, defensibly arrayed," as early as May. But no such muster seems to have taken place, and it was not till September that a blow was struck. In the middle of that month an army was raised in the Midlands with which the King took the field. A summons was then sent to Salisbury, who lay at Sherif Hoton in his northern lands, bidding him come to London. Remembering what had happened to his son on his last visit to the King, Salisbury went not, but took the summons, combined with the mustering of the King's forces, as an alarm of war. Collecting some three thousand of his Yorkshire tenants, he marched off to seek his brother-in-law York, who was lying at Ludlow. At the same time he sent messengers to his son at Calais, bidding him cross over at once to join him.
Warwick, seeing that the crisis was come, took two hundred men-at-arms and four hundred archers of the garrison of Calais, under Sir Andrew Trollope a veteran of the French War, and crossed to Sandwich. He left Calais, where lay his wife and his two daughters, in charge of his uncle, William Neville Lord Fauconbridge, "a little man in stature but a knight of great reverence." Warwick marched quietly through London, and crossed the Midlands as far as Coleshill in Warwickshire without meeting an enemy. There he just avoided a battle, for Somerset, with a great force from his Wessex lands, was marching through the town from south-west to north-east the same day that Warwick traversed it from south-east to north-west; but as it happened they neither of them caught any sight or heard any rumour of the other.
While Warwick was taking his way through the Midlands, decisive events had been occurring. When the Queen, who lay at Eccleshall in Staffordshire, heard that Salisbury was on his way to York's castle of Ludlow, she called out all her new-made friends of the north-west Midlands, and bade them intercept the Earl. Lord Audley their leader was given a commission to arrest Salisbury and send him to the Tower of London. All the knighthood of Cheshire and Shropshire came together and joined Audley, who was soon at the head of nearly ten thousand men. With this force he threw himself across Salisbury's path at Blore Heath near Market Drayton on September 23rd. The old Earl refused to listen to Audley's summons to surrender, entrenched himself on the edge of a wood and waited to be attacked. Audley first led two cavalry charges against the Yorkist line, and when these were beaten back by the arrows of the northern archers, launched a great column of billmen and dismounted knights against the enemy. After hard fighting it was repulsed, Audley himself was slain, and the Lancastrians drew back, "leaving dead on the field most of those notable knights and squires of Chesshire that had taken the badge of the Swan."
In the night Salisbury drew off his men and marched round the defeated enemy, who still lay in front of his position. A curious story is told of his retreat by the chronicler Gregory. "Next day," he says, "the Earl of Salisbury, if he had stayed, would have been taken, so great were the forces that would have been brought up by the Queen, who lay at Eccleshall only six miles from the field." But the enemy knew nothing of Salisbury's departure, "because an Austin friar shot guns all night in the park at the rear of the field, so that they knew not the Earl was departed. Next morrow they found neither man nor child in that park save the friar, and he said that it was for fear that he abode in that park, firing the guns to keep up his heart."
Salisbury was now able to join York at Ludlow without further molestation, and Warwick came in a few days later without having seen an enemy. The Duke and the younger Earl called out their vassals of the Welsh March, and their united forces soon amounted to twenty thousand men. They made no hostile movement however, though the Lancastrian force defeated at Blore Heath was now being joined by new reinforcements and lay opposite them in great strength. But the Duke and the two Earls went forward to Worcester, and there in the cathedral took a solemn oath that they meant nothing against the King's estate or the common weal of the realm. They charged the Prior of Worcester and Dr. William Lynwood to lay before the King a declaration "that they would forbear and avoid all things that might serve to the effusion of Christian blood," and would not strike a blow except in self-defence, being only in arms to save their own lives.
The refusal of the Yorkist lords to assume the offensive, if creditable to their honesty, was fatal to their cause. For the next three weeks the levies of Northern and Central England came pouring into the Queen's camp, and the King himself, waking up for once, assumed the command in person. A curious record in the preamble of an Act of Parliament of this year tells us how he buckled on his armour, "and spared not for any impediment or difficulty of way, nor intemperance of weather, but jeopardied his royal person, and continued his labour for thirty days, and sometimes lodged in the bare field for two nights together, with all his host, in the cold season of the year, not resting in the same place more than one night save only on the Sundays." About October 12th, the King, whose army now amounted to as many as fifty thousand men, pushed slowly forward on to Ludlow, putting out as he went strongly-worded proclamations which stigmatised the Duke and the Earls as traitors, and summoned their followers to disperse, promising free pardon to all save Salisbury and the others who had fought at Blore Heath.
