His hopes of Yorkist aid were over with the failure of Clarence; and, covered as he was with Lancastrian blood, he turned to the House of Lancaster.

Margaret was summoned to the French court; the mediation of Lewis bent her proud spirit to a reconciliation on Warwick's promise to restore her husband to the throne, and after a fortnight's struggle she consented at the close of July to betroth her son to the earl's second daughter, Anne Neville.

Such an alliance shielded Warwick, as he trusted, from Lancastrian vengeance, but it at once detached Clarence from his cause.

Edward had already made secret overtures to his brother, and though Warwick strove to reconcile the Duke to his new policy by a provision that in default of heirs to the son of Margaret Clarence should inherit the throne, the Duke's resentment drew him back to his brother's side.

But whether by Edward's counsel or no his resentment was concealed; Clarence swore fealty to the house of Lancaster, and joined in the preparations which Warwick was making for a landing in England.
[Sidenote: Edward driven out] What the Earl really counted on was not so much Lancastrian aid as Yorkist treason.
