Henry Bolingbroke, Earl of Derby, son of the most powerful magnate in England, was a golden child blessed with every advantage. While Richard tried to get his royal feet under the throne, Bolingbroke left the wife to bring up the children and headed out to fulfil the image of the perfect medieval knight.
The Tournament at St Inglevert
In a fever of excitement, Henry and many famous companions - Thomas Mowbray among them - travelled to Calais and thence to St Inglevert.
