Francis II
Montmorency's attempt to relieve St Quentin on 10 August 1557 led to his defeat and capture by Spanish Habsburg forces. He was not released until October 1558 at the Peace of Cateau-Cambrésis.

However, his son was appointed marshal by way of indemnity. He himself retired to his estates.
