Order organized into three ranks
Jerusalem, IsraelRaymond du Puy, who succeeded Gerard as master of the hospital in 1118, organized a militia from the order's members, dividing the order into three ranks: knights, men at arms, and chaplains. Raymond offered the service of his armed troops to Baldwin II of Jerusalem, and the order from this time participated in the crusades as a military order, in particular distinguishing itself in the Siege of Ascalon of 1153.
