 The Dauphin despairingly sought allies, and found them amongst the Scots and the Castilians.In 1418 Robert Stewart, Duke of Albany appointed his son, John Stewart, 2nd Earl of Buchan, Chamberlain of Scotland to command the Scottish expeditionary force, the largest army that medieval Scotland had ever sent abroad.7000-8000 men arrived at La Rochelle in October 1419 and made their way to Tours to greet the Dauphin.
