THOMAS MOWBRAY: My name is Thomas Mowbray, Duke of Norfolk; Who hither come engaged by my oath-- Which God defend a knight should violate!-- Both to defend my loyalty and truth To God, my king and my succeeding issue, Against the Duke of Hereford that appeals me And, by the grace of God and this mine arm, To prove him, in defending of myself, A traitor to my God, my king, and me: And as I truly fight, defend me heaven!
