The lords spiritual and temporal made a similar grant, on the consideration "that the kyng oure soverayn lord is disposed by the grace of God in his owne persone to passe forth of this his seid reame with an armee roiall, for the saufegarde of the same reame, and the subduyng of the auncien ennemyes of hym and of his seid reame."[26] In the next session, on the 8th April 1473, the commons granted to the king a fifteenth and a tenth, because, among other causes, "that ye verraily entend, as we understond, to aredye youre self, by all measnes to you possible, in youre moost noble persone to goo, departe, and passe with an arme roiall to the parties outward, to subdue by the myght of God youre and oure auncien enemyes, to the weele of you and prosperite of this youre reame."[27] Notwithstanding these earnest intentions and costly preparations, the season of 1473 wore away without any embarkation for France; and, at the close of the session on the 1st of February 1473-4, the chancellor, by the king's command, informed the commons that the parliament was prorogued to the 9th of May following,[28] "because in the matter of foreign war the king was not certainly {xix} informed of the disposition of his brother of Burgundy, and on that account he had lately sent his ambassadors to his said brother." The treaty with Burgundy was concluded in July 1474. The principal documents[29] respecting it bear date on the 25th of that month, on which day they were ratified both by king Edward and duke Charles. The former undertook to land in Normandy, or in other parts of France, with more than ten thousand men, before the 1st of July following (_i.e._ 1475); and the latter agreed to support the king's part in person and with his forces, in order to accomplish the recovery of the duchies of Normandy and Aquitaine, and the kingdom and crown of France, from Louis, then unjustly occupying them. The king engaged not to treat with Louis, without the consent of the duke of Burgundy; and the duke in like manner covenanted not to treat with him without the consent of king Edward. Henceforth Louis was to be deemed and proclaimed their common enemy.
