"As for Caister, Daubeney and Berney be dead, and diverse others greatly hurt, and we be sore lacks of victuals, gunpowder, men's hearts, lack of surety of rescue. I have done what I can, I cannot be in every place... We are like to lose it. I dread me sore lest the Bastard of Fauconberg come with too great a power for us to withstand... if God do not send us hasty rescue it must needs be yielded."

John Paston III, letter to his brother Sir John Paston II, written from Caister Castle, Norfolk, September 1469. The castle was under siege by forces of the Duke of Norfolk.
