The Duke of Burgundy made the reception of these ships in French harbours the pretext for a new strife with Lewis; he seized the goods of French merchants at Bruges and demanded redress.

Lewis was in no humour for risking for so small a matter the peace he had won, and refused to see or speak with Warwick till the prizes were restored.

But he was soon driven from this neutral position.

The violent language of Duke Charles showed his desire to renew the war with France in the faith that Warwick's presence at the French court would ensure Edward's support; and Lewis resolved to prevent such a war by giving Edward work to do at home.
He supplied Warwick with money and men, and pressed him to hasten his departure for England.

"You know," he wrote to an agent, "the desire I have for Warwick's return to England, as well because I wish to see him get the better of his enemies as that at least through him the realm of England may be again thrown into confusion, so as to avoid the questions which have arisen out of his residence here." But Warwick was too cautious a statesman to hope to win England with French troops only.
