Morton landed with Warwick at Dartmouth on the 13th of September 1470, but the battle of Tewkesbury finally shattered the Lancastrian hopes, and Morton made his peace with Edward IV., probably through the mediation of Archbishop Bourchier.
Some excuse must be found for getting rid of the queen and her friends, and the doubtful legitimacy of the Lancastrian claim to the crown afforded such an excuse.
In politics, the queen-mother, who had the private guardianship of her boys, the king and the dukes of Albany and Ross, turned from the Lancastrian to the Yorkist side, while Kennedy and his party (Lancastrians) were accused of endangering Scotland to please France.
Morton no doubt impressed Lancastrian traditions upon Henry VII., but he cannot be credited with any great originality as a statesman, and Henry's policy was as much Yorkist as Lancastrian.
When it is added that the Lancastrian party avoided holding a parliament for three years, because they dared not face it, and that the French were allowed to sack Fowey, Sandwich and other places because there was no English fleet in existence, it is not wonderful that many men thought that the cup of the iniquities of the house of Lancaster was full.
But there was bitterness and mistrust between the old Lancastrian faction and the Nevilles, and Queen Margaret Restorarefused to cross to England or to trust her son in the Henry Vi.
In 1470, Archbishop Neville took the oath of allegiance to Edward, but during the short Lancastrian restoration which compelled Edward to cross to Holland, Neville acted as chancellor to Henry VI.; and when the tide once more turned he again trimmed his sails to the favouring breeze, making his peace with Edward, now again triumphant, by surrendering Henry into his hands.
Indeed he was accepted by the English people as the benefactor who had delivered them from anarchy; and if they murmured at his love of hoarding, and cursed his inquisitors Empson and Dudley, they had no wish to change the Tudor rule, and were far from regarding the times of the Lancastrian experiment as a lost golden age.
After Blore Heath Richard was attainted by the Lancastrian parliament, and returned to Dublin, where the colonial parliament acknowledged him and assumed virtual independence.
The rivalry between them was purely personal; both were prepared to go on with the Lancastrian experiment, the attethpt to govern the realm in a constitutional fashion by an alliance between the king and the parliament; both were eager persecutors of the Lollards; both were eager to make profit for England by interfering in the civil wars of the Orleanists and Burgundians which were now devastating France.
