of Burgundy, Warbeck landed at Deal in Kent, hoping for a show of popular support. They were confronted by locals loyal to Henry VII in the ensuing Battle of Deal. Warbeck's small army was routed and 150 of the pretender's troops were killed without Warbeck even disembarking. He was forced to retreat almost immediately, this time to Ireland. There he found support from Maurice FitzGerald, 9th Earl of Desmond, and laid siege to Waterford, but, meeting resistance, he fled to Scotland. Henry pardoned Warbeck's Irish supporters, remarking drily that "I suppose they will crown an ape next". Warbeck was well received by James IV of Scotland, who realised that his presence gave him international leverage. As Ferdinand and Isabella of Spain were negotiating an alliance with Henry VII, James IV knew that Spain would help him in his struggles with England in order to prevent the situation escalating into war with France. Spanish ambassadors arrived in Edinburgh, and later Pedro de Ayala was established as a resident ambassador during the crisis. Warbeck married Lady Catherine Gordon, a daughter of George Gordon, 2nd Earl of Huntly. The marriage was celebrated in Edinburgh with a tournament. James gave Warbeck clothes for the wedding and armour covered with purple silk. Historian Katie Stevenson suggests the clothing bought for the tournament shows Warbeck fought in a team with the king and four knights. A copy of a love letter in Latin obtained by Pedro de Ayala is thought to be Warbeck's proposal to Lady Catherine. However, James's biographer Norman Macdougall comments that it is clear that nobody, with the possible exception of Margaret of Burgundy, took seriously his claim to be the prince; his marriage to a junior Scots noblewoman was scarcely what might be expected for a potential king of England. In September 1496, James IV prepared to invade England with Warbeck. A red, gold and silver banner was made for Warbeck as the Duke of York; James's armour was gilded and painted, and the royal artillery was prepared. John Ramsay of Balmain (who called himself Lord Bothwell) described the events for Henry VII. He saw Roderic de Lalanne, a Flemish knight, arrive with two little ships and 60 German soldiers and meet James IV and talk to Warbeck. In Edinburgh Castle Ramsay saw two great French guns called 'curtalds,' 10 falconets or little serpentines, and 30 iron breech-loading 'cart guns' with 16
