Louis VI
He initially held the lordship of Bray-sur-Seine, in Champagne. In 1105, he attacked his brother's castle of Montlhéry, where his cousin Lucienne de Rochefort, fiancée of Louis VI of France, lived. He invested the castle, but could not succeed in capturing the "donjon". Louis VI soon arrived to relieve the siege, and Milo was obliged to retire.
