 The frontier with the Saracen, not very attractive for people who wished for a life of quiet work, was a refuge for adventurers, of people who enjoyed living with risks and who lived by the fist and by looting enemy territory.During the wars they joined the army, most of the time without a salary, but in exchange for rights on the loot, and being fed.Their mission consisted of exploring the land where the army was advancing, standing at forefront and flanks, harassing the enemy, attacking their garrisons by surprise and intercepting their convoys.
