Little is known about the life of the Scottish king in France, except that Château Gaillard was given to him for a residence, and that he was present at the bloodless meeting of the English and French armies in October 1339 at Vironfosse, now known as Buironfosse, in the Arrondissement of Vervins.
He had at least six knights in his train, and took the field in the campaign which ended bloodlessly at Buironfosse (1339).
He accompanied his father to Paris in 1339 and took part in the campaign against the English near Buironfosse, part of the Hundred Years' War.
