The Battle of Volturnus (1860), at the conclusion of Garibaldi's Expedition of the Thousand, partially took place in and around Capua. Prior to the battle, the Neapolitan army – defeated in earlier engagements – was rebuilt in Capua under marshal Giosuè Ritucci. After fighting elsewhere in which the Neapolitans were ultimately defeated, the last of them – c. 3,000 troops Colonel Perrone – were holed up in Capua. The city was attacked by the Garibaldines and one Piedmontese regular Bersaglieri battalion, and captured.
