For a time an open breach between the king and the King-maker was delayed, and Edward's throne seemed firmly set. His position was made surer by the capture of the old King Henry VI., who was caught in Lancashire, where he had been lurking obscurely for some time. When Edward had placed him in the Tower of London, he thought that all his troubles were over. He forgot the unhealthy condition of the realm, the blood-feuds that reigned in every county, and the general disorganization of society that had resulted from six years of civil war and from the wholesale transference of lands and property that had accompanied it. Above all, he overlooked the vast power that had fallen into the hands of the great military peers, and especially of his ambitious cousin Warwick.
In 1467 Edward put his strength to the trial by dismissing all the King-maker's friends from office, and by ignominiously disavowing an embassy to France on which he had sent his cousin. From sheer desire to humiliate the great earl, he concluded an alliance with Charles the Rash, Duke of Burgundy, the deadly enemy of France, because he knew that Warwick was opposed to such a tie. He gave his sister Margaret to be the duke's wife, and made Warwick escort her on her embarkation for Flanders.
Conspiracy of Warwick.
The earl replied by setting treasonable intrigues on foot. He leagued himself with the king's younger brother George, Duke of Clarence, Shakespeare's "false, fleeting, perjured Clarence," a discontented young man of a very unamiable character. Warwick agreed to give his eldest daughter, the heiress of his vast estates, to the duke, and they swore to compel Edward to drive away the Woodvilles, and rule only under their guidance.
Defeat and capture of Edward.
Warwick and Clarence were completely successful in their plot. They secretly suborned a rebellion in Yorkshire, under Sir John Conyers, one of Warwick's relatives, who was aided by the Neville retainers, as well as by the discontented Lancastrians of the North. Conyers called himself "Robin of Redesdale," and gave himself out as the champion of the poor and the redresser of grievances—much as Cade had done fifteen years before. He beat the king's army at Edgecote Field, near Banbury, and then Warwick and Clarence appeared upon the scene and apprehended Edward at Olney. They beheaded Earl Rivers, the father of all the Woodvilles, and Herbert, Earl of Pembroke, the king's chief confidant. After keeping Edward some months in durance, they released him, on his undertaking to govern according to their desires (1469).
Warwick driven from England.
But the spirit of Edward always rose in times of trouble; he cast off his sloth, and plotted against the plotters. Taking advantage of an ill-planned Lancastrian rising in Lincolnshire, he raised a great army, and suddenly turned it against his disloyal brother and cousin. Warwick and Clarence were chased all across England, from Manchester to Dartmouth, and barely escaped with their lives by taking ship to France.
He joins the Lancastrians.
Furious at his failure, the King-maker resolved to sacrifice all his prejudices and predispositions to revenge. He met the exiled Queen Margaret at Angers, and proposed to her to restore Henry VI. to the throne, and make an end of the ungrateful Edward. After long doubting, Margaret resolved to take his offer, though she hated him bitterly, and never trusted him. To bind the alliance, Edward, Prince of Wales, the queen's young son, was married to Anne Neville, the earl's second daughter.
