Sorry, I was unable to the temptation of to bring the war to England
Wikipedia: <Due to the hostile politics of John of Gaunt, 1st Duke of Lancaster, the new king Henry II of Castile joined the French side during the Hundred Years´War and declared war on England. As a result, Sánchez de Tovar led the Castilian fleet along with the French Jean de Vienne to South England and sacked the Isle of Wight and the English ports of Rye, Rottingdean, Lewes, Folkestone, Plymouth, Portsmouth and Hastings. In 1380 the joint fleet sailed up the Thames and burned Gravesend, a short distance from London>
Could this evolve into a real invasion?
