Hall's Chronicle 1492. After that, all this army was arrayed and even ready to set forward whereof were chieftains and leaders, Jasper Duke of Bedford (age 61), and John, Earl of Oxford (age 50) beside other the King (age 35) sent Christopher Urswick (age 44) almoner, and syr John Wriothesley knight to Maximilia (age 33), to certify him that the King (age 35) was all in a readiness, and would shortly arrive in the continent land, as soon as he were advertised that Maximilian (age 33) and his men, were ready and prepared to join with him. The Ambassadors sailed into Flanders, and after their message done, they sent two letters in all hast to King Henry (age 35), the which not only sore unquieted and vexed him, but also caused him to take more thought, care and study on him then he did before: for they declared that no prince could be more unprovided or more destitute of men and armure, no more lacking all things, appertaining to war than was Maximilian (age 33), and that he lay lurking in a corner, sore sick of the flux of the purse, so that he had neither men, horses, munitions, armour nor money, nevertheless his mind and will was good, if his power and ability had been correspondent and therefore there was no trust to be put in his aide or puissance. Their letters both appalled and made sorrowful the King of England (age 35), which like a prudent prince did well consider and ponder, that it were both jeopardous and costly, for him alone to enterprise so great a war. And on the other part, if he should desist and leave of his pretended purpose, all me might call him coward and recreant prince. Beside this, he thought that his own nation would not take his tarrying at home in good nor favourable part, considering that syth they had given so large money for the preparation of all things necessary and convenient for the same, they might conceive in their heads and imagine, that under colour and pretence of a dissimulated war he had exacted of the notable sums of money, and now the treasure was once paid, then the war was done, and his coffers well enriched, and the commons impoverished. So that at this time he doubted and cast perils on every side and part, and beside this he was not a little sorry that Maximilia (age 33) author of this war did absent himself and defraud him of his society and assistance. And while he studied and mused what counsel he should best take in such a doubtful and sudden case, he like a grave prince, remembering the saying of the wise man, work by counsel and thou shall not repent the, assembled together all his lords and other of his private counsel, by whose minds it was concluded and determined, that he should manfully and courageously persevere and precede in this broached and begun enterprise, recording well with themselves, and affirming plainly that all chivalry and martial prowess, the more difficult and heard that it is to attain to, the more renowned is the glory, and the fame more immortal of the vanquisher and obtainer. Therefore by this counsel of his friends and senate, he made Proclamation that every man should set forward into France, and yet not opening how Judasly Maximilian had deceived him, least that they knowing the whole fact, should not be so courageous to go toward that battle and precede forward on their journey. And therefore, to provide and force all perils and dangers that might accidentally ensue, he so strengthened, multiplied and augmented his army in such number before he took ship, that he with his own power might discourage and overcome the whole puissance of his adversaries.
