On the sides of the crescent, foot-archers were placed, and this enabled them to destroy the Gothic cavalry through enfilading fire. (This disposition of the archers and their effect upon the battle is strikingly parallel to the later Battle of Agincourt.) Next, Narses placed much of his cavalry on the immediate sides of the dismounted infantry. Normally the cavalry would have been behind the centre, but they were not meant to aid any of the struggling line. Instead they were used to deliver a surprise attack on the Goths when they became fully enveloped. Narses knew that Totila would take the advantage of attacking the "weak" centre, and therefore allowed Narses to completely destroy the Ostrogothic army. Procopius said that Totila had been "out-generalled by his own folly", because Totila had instructed his troops to only engage with spears, as he thought a quick strike would win the battle.
