Chronicle of England by Jean de Waurin Volume 6. [22 May 1455]. Then the two forces, seeing each other and advancing, began to march, and each side fired so accurately that from the arrows and gunpowder the horses kicked up, the air became so thick that the sun lost its brightness. The battle was so terrible that there was no one who spared brother or cousin, so much so that in the end the King lost the day. Some say, as I was informed, that the King was wounded by an arrow in the arm, and the Duke of Somerset (age 49), the Earl of Northumberland (age 62), Lord Clifford (age 41), and many other great lords and gentlemen died in the battle.
And the King was taken by some of his men towards London, but the Duke of York (age 43) did not pursue him; rather, very pleased with his victory, he returned to York with the two earls mentioned above.
