The Siege of Hirson was a minor siege that took place in July 1636 (exact date unknown). A Spanish contingent under Cardinal-Infante Ferdinand would capture the city whilst two more important sieges were ongoing, namely the Siege of La Capelle and the Siege of Le Catelet (1636). This siege battle, along with the two other more important ones would lead to an important precursor to the oncoming Crossing of the Somme campaign led by the Cardinal-Infante.[1]
