When a king of inferior power or one who is provided with the aid of forts and friends has to make a short march in order to capture an enemy without waging war or to receive some expected profit, he may request a third king of superior power involved under various troubles and misfortunes the help of the latter's army in return for the payment of a share in the profit less than the strength of the army supplied deserves. If the king to whom this proposal is made is powerful enough to retaliate, he may declare war; but otherwise he may accept the proposal.
