The steady volleys of Kempts light infantry were fatal to the French, who fell back in disorder under a bayonet charge of the victors, with the loss of some 2700 men.
Volunteers discharged a Ita volleys which were returned by the regulars.
Technically, the details of the action show that, while not markedly better in a mï¿½e than the war-seasoned French, the British infantry had in its volleys a power which no other troops then existing possessed, and it was these volleys that decided the day even more than the individual stubbornness of the men.
Junot, believing the allied August21, left to be weakly held, attacked it without reconnoitring, but Wellesley's regiments, marched thither behind the heights, sprang up in line; and under their volleys and bayonet charge, supported by artillery fire, Junot's deep columns were driven off the direct road to Lisbon.
The Prussians, having seen the cavalry whilst yet at a distance, ceased firing, formed their skirmishers into groups, and the closed supports standing in deployed lines, two deep, shattered the cavalry with volleys and file-firing, as with blown and exhausted horses they endeavoured to close with their adversaries.
