The interest attached by all antiquaries to the Household Book of Henry Algernon Percy, fifth Earl of Northumberland, edited by the Bishop of Dromore in 1770, will probably offer a sufficient apology for my troubling the Society, through you, with a Document relating to the same Nobleman, whose magnificence, love of the arts, and patronage of literature, entitle him to the admiration and respect of all acquainted with his character. We are informed by Hall,a the contemporary historian, that in the beginning of the fifth year of King Henry the Eighth, the Earl of Northumberland was one of the noblemen selected to take a part in the expedition then preparing against France, and that he was present at the sieges of Terouenne and Tournay, in the rearward division of the army, under the command of Lord Herbert, Lord Chamberlain, afterwards created Earl of Worcester. This statement is illustrated by an article (communicated by the Earl of Egremont), annexed to the reprint of the Northumberland Household Book in the “Antiquarian Repertory,” vol. iv. second edit, intitled “Equipage of the right honourable Henry Earl of Northumberland, at the siege of Turwin, in France, 5 Henry VIII”b It thence appears, that the King's first letter of summons to the Earl, was dated from Greenwich, 22 Feb. anno regni 4, [1512–13] ordering him to raise 500 men, of which 100 were to be demi-lances on horseback, 300 archers, and 100 bill-men on foot. A second letter was sent on the 13th of April following, signifying the King's pleasure, that the Earl and his retinue sh⊙uld repair to the ports of Dover or Sandwich by the 28th of May; which was immediately complied with, since we know from Hall, that the whole of the troops under Lord Herbert landed at Calais on the 31st of that month. In the same MS. is an account of the “parcels of stuffe” prepared for the Earl and his attendants, which is extremely curious, as it shews minutely the war-equipment of a nobleman of the first rank at this period, and forms a very amusing supplement to the information previously afforded of the same nobleman's style of living in domestic life.
