However, the gendarme cavalry, when properly employed, could still be a decisive arm, as they could deliver a potent shock attack and remained fairly maneuverable despite the extremely heavy armour they now wore to defend themselves from increasingly powerful firearms. At some battles, such as at Seminara, Fornovo and Ravenna, they clashed with their heavily armoured opposite numbers, and prevailed, dominating the battle. In others, such as at Marignano, they were part of a "de facto" combined arms team, operating in conjunction with infantry and artillery to achieve battlefield victory against an all-infantry foe. They could also function, by plan or by chance, as a decisive reserve which could enter into a confused battle and crush disordered enemy infantry. The prime example of this would be at Ravenna, where the gendarmes, having just driven the Spanish cavalry off the field, then reversed the results of the infantry clash in which the Spanish had prevailed, riding down the disordered Spanish foot.
