The bayonet was used to finish off actions brought to near completion by the musketry and also in skirmishes, as reported by contemporary observers: "opposing regiments when formed in line and charging with fixed bayonets, 'never' meet a struggle hand to hand and foot to foot; and this for the best possible reason, that one side turns and runs away as soon as the other comes close enough to do mischief". Here, fear of the bayonet, it seems, rather than the bayonet itself tended to be seen as the deciding factor in the outcome of a battle. On occasion, however, the bayonet could be used extensively as was the case during the Battle of Fuentes de Onoro.
