Plumpton Correspondance by Edward Plumpton, p.67
On the 29th of the same month, being Palm Sunday, Sir William Plumpton was present at the decisive battle of Towton, otherwise Saxton Field; where William, his son and heir apparent, it seems was slain, and he himself either made prisoner by the enemy on that day, or driven by the adverse fortune of his party shortly afterwards to throw himself on the mercy of Edward. On the 13th of May he cane before Robert Danby, Chief Justice, in the city of York, and gave bond for the payment of L2000 before the feast of Pentecost next ensuing, whereupon the following writ was issued on his behalf.
íEdward, by the grace of God, King of England and France and Lord of Ireland, we will and straitly charge all our true liegemen and subgitts, that none of them upon paine of death, under any colour or occasion whatsoever it be, robbe nor spoile William Plonpton of Plompton, in our county of York, knight, nor one of his servants (...).
The term for redeeming of this bond having elapsed, on the 12th of July 1461, Sir William Plumpton surrendered himself a prisoner at the Tower of London; (...). He obtained general pardon, 5 Feb. 1 Edw. IV. 1461-2 and was subsequently, 10 Sept. 2 Edw.IV. 1462, released from all claim by reason of his bond. But notwithstanding Sir William Plumpton had afresh letters of pardon dated 30 Aug. 3 Edw. IV. 1463, he was, it seems, restricted from returning home into the North; and was at one time in jopardy of his life, by reason of the denunciation of one David Routh, of Westminster (...).
Upon these charges Sir William Plumpton was tried before the earl of Worcester (...). Having been acquitted, he obtained a warrant from the Constable to be rid of all further molestation on that behalf, dated 20 Jan. 3 Edw. IV. 1463-4, as also the following brief from the King.
