We have seen that holding a fief usually implies military service, and that if the estate falls to a woman the suzerain can administer the property until the maid is of marriageable age, and then give her to some competent liegeman. It is about the same if the heir is a boy. The overlord can exercise guardianship over the fief until the lad is old enough to lead out his war band and otherwise to prove a desirable vassal. Even when the vassals are of satisfactory sex and age, the suzerain is entitled to a _relief_, a money payment, whenever an old knight dies and his battle-worthy son takes over the barony.[39] This is always a fairly heavy lump sum; and is still heavier if the fief goes not to the son, but to a collateral heir. Also, when the vassal wants to sell his fief to some stranger, not merely must the suzerain approve the change, but he is entitled to an extra large fee, often as much as three years' revenue from the entire holding. Nevertheless, when all is said, many fief holders act as if they were anything but humble vassals. Happy is many a suzerain when he is so exempt from squabbles with his feudal equals and his own overlord that he can compel his loyal lieges to execute all their promises, and when he can indulge in the luxury of dictating to them the manner whereby they must rule their lands. Some of the mottoes of the great baronial houses testify how little the feudal hierarchy counts with the lord of a few strong castles. Boast the mighty Rohans: "Dukes we disdain: Kings we can't be: _Rohans_ are we!" And still more arrogant is that of a seigneur whose magnificent fortress-château is in the process of erection; "No king am I, no prince, no duke: I'm just the Sire of Coucy." And to be "Sire of Coucy" means to dispose of such power that when the canons of Rheims complain to King Philip against his deeds of violence, the king can merely reply, "I can do no more for you than _pray_ the Sire of Coucy to leave you unmolested." Sometimes, in addition to money payments or personal or military service, a vassal is required to make symbolic gifts in token of loyal intentions. Thus annually Conon sends to the Duke of Quelqueparte three black horses; while for his holdings of the local abbey, every June he presents the abbot with a basket of roses and a bunch of lilies, and many other estates are burdened with some such peculiar duties.[40] [Sidenote: Barons Largely Independent]
