In the olden time, when a Knight had distinguished himself by conspicuous gallantry, it was the custom to mark his meritorious conduct by prompt advancement on the very field of battle. In such a case, the point or points of the good Knight’s Pennon were rent off, and thus the small Flag was reduced to the _square_ form of the Banner, by which thenceforth he was to be distinguished. FROISSART, in his own graphic manner, has described the ceremonial which attended the first display of the Banner of a newly-created Banneret on the field of battle. Sir JOHN CHANDOS, one of the Knights Founders of the Garter, appeared with his maiden Banner on the field, on the morning of the battle of Naveret, in Castile, April 3rd, 1367:--“He brought his banner in his hands,” says the chronicler, “rolled up” (rolled round the staff), “and said to the PRINCE OF WALES”--it was the BLACK PRINCE,--“’My Lord, behold, here is my Banner: I deliver it to you in this way,”--still rolled round the staff, that is--“’that it may please you to display it, and that this day I may raise it; for, thank God, I have land and heritage sufficient to support the rank as it ought to be!’ Then the Prince and the King”--Don PETRO, King of Castile--“took the Banner, which was of silver with a sharp pile gules, between their hands by the staff, and displayed it, and returned it to him, the Prince saying--’Sir John, behold your Banner; may God grant you may do your duty!’ Then Sir JOHN CHANDOS bore his Banner (displayed) to his own Company, and said--’Gentlemen, see here my Banner and yours; preserve it as your own!’” We see that, like another hero of a later period, the BLACK PRINCE held the maxim--“England expects every man to do his duty.” [Illustration: No. 414.--Seal of Earl John Holland, Admiral of England, &c., A.D. 1436.] Quarterings, Marks of Cadency, and Differences (but not impalements) are blazoned on Banners under the very same conditions that they appear on Shields of Arms. For example, the Banners, as well as the Shield, on the seal of Sir Robert de Hungerford, No. 392, are Differenced with a label for Cadency, and thus are distinguished from the corresponding Banners and Shield on the Seal of Sir Robert’s father, No. 391. Crests, Badges, Supporters, and other external accessories and ornaments of Armorial Shields have no place on Banners, a Banner representing a Shield, and being charged as a Shield. In the seventeenth century, however, English Banners sometimes were charged with Achievements of Arms, including all the accessories and ornaments of Shields.
