A subsidy of a tenth and fifteenth was fixed by Edward III.

at twenty-nine thousand pounds, which, in the reign of Henry VI., made only fifty-eight thousand pounds of our present money.

The parliament granted only one subsidy during the course of seven years, from 1437 to 1444.
The duke reminded the council of the dying advice of the late king, that none of these prisoners should on any account be released, till his son should be of sufficient age to hold himself the reins of government.
The cardinal insisted on the greatness of the sum offered, which, in reality, was nearly equal to two thirds of all the extraordinary supplies that the parliament, during the course of seven years, granted for the support of the war.

And he added, that the release of this prince was more likely to be advantageous than prejudicial to the English interests; by filling the court of France with faction, and giving a head to those numerous malecontents whom Charles was at present able with great difficulty to restrain.

The cardinal's party, as usual, prevailed: the duke of Orleans was released, after a melancholy captivity of twenty-five years:[*] and the duke of Burgundy, as a pledge of his entire reconciliation with the family of Orleans, facilitated to that prince the payment of his ransom.
