Letters. 13 Feb 1254. Letter XII. Eleanor of Provence Queen Consort England (age 31) and Richard of Cornwall 1st Earl Cornwall (age 45) to King Henry III of England (age 46).

To their most excellent lord, the lord Henry, by God's grace the illustrious king of England, lord of Ireland, duke of Normandy and Aquitaine, and earl of Anjou, his most devoted consort Eleanora, by the same grace queen of England, and his devoted and faithful Richard earl of Cornwall, send health with all reverence and honour.

Be it known to your revered lordship that the lords the earl marshall (age 45) and John de Bailiol (age 46), being hindered at sea by a contrary wind during twelve days, came to us in England on the Wednesday after the Purification of Blessed Mary last past.

We had been treating with your prelates and the magnates of your kingdom of England before the advent of the said Earl and John, on the quinzaines of St. Hilary last past about your subsidy, and after the arrival of the said Earl and John, with certain of the aforesaid prelates and magnates, the archbishops and bishops answered us that if the King of Castile (age 32) should come against you in Gascony each of them would assist you from his own property, so that you would be under perpetual obli gations to them; but with regard to granting you an aid from their clergy, they could do nothing without the assent of the said clergy; nor do they believe that their clergy can be induced to give you any help, unless the tenth of clerical goods granted to you for the first year of the crusade, which should begin in the present year, might be relaxed at once by your letters patent, and the collection of the said tenth for the said crusade, for the two following years, might be put in respite up to the term of two years before your passage to the Holy Land; and they will give diligence and treat with the clergy submitted to them, to induce them to assist you according to that form with a tenth of their benefices, in case the King of Castile should attack you in Gascony; but at the departure of the bearer of these presents no subsidy had as yet been granted by the aforesaid clergy. Moreover, as we have elsewhere signified to you, if the King of Castile should come against you in Gascony, all the earls and barons of your kingdom, who are able to cross the sea, will come to you in Gascony, with all their power; but from the other laymen who do not sail over to you we do not think that we can obtain any help for your use, unless you write to your lieutenants in England firmly to maintain your great charters of liberties, and to let this be distinctly perceived by your letters to each Sheriff of your kingdom, and publicly proclaimed through each county of the said kingdom; since, by this means, they would be more strongly animated cheerfully to grant you aid; for many persons complain that the aforesaid charters are not kept by your sheriffs and other bailiffs as they ought to be kept. Be it known, therefore, to your lordship, that we shall hold a conference with the aforesaid clergy and laity at Westminster, in the quinzaines of Passover next, about the aforesaid aid, and we supplicate your lordship that you will write us your good pleasure concerning these affairs with the utmost possible haste. For you will find us prepared and devoted, according to our power, to solicit the aforesaid aid for your use, and to do and procure all other things ....* which can contribute to your convenience and the increase of your honour. Given at Windsor [Map], the 13th of February, in the thirty-eighth year of your reign.
