The siege of La Capelle took place from the 2nd to the 8th of July in 1636 during the Franco-Spanish War (1635–1659) in which a Spanish army under Cardinal-Infante Ferdinand managed to seize the fortress of La Capelle from the French army retreating from a previous defeat taking place at Leuven.
The main goal of the campaign was to threaten Paris, hence the capture of La Capelle was deemed vital.
[3] The ensuing 1636 campaign led by the Cardinal-Infante would face quite the success with one of the first targets within France to fall being La Capelle.
The Spanish would set up the first artillery batteries south of the fortress in front of the main entrance redoubts.
With the much depleted French supplies and lack of artillery, the only attempt to repel the Spanish was made in a sortie at the main frontal battery of the fortress.
