France

• Warwick favoured France as it was a bigger power and market for English goods
• Louis XI's accession to the French throne stopped Channel issues
• in October 1463 Louis signed a truce with Edward
• Louis couldn't afford to support Lancastrians as he needed peace with Burgundy
• Edward invaded the Channel in July 1461
• he failed to marry Isabella ( Henry of Castile's sister) in 1464
• memories of the hundred years war were still fresh making it difficult to make alliances work
