On the 10th of October the king’s army was in full march, his Majesty, generalissimo, the Earl of Lindsey, general of the foot, Prince Rupert, general of the horse; and the first action in the field was by Prince Rupert and Sir John Byron. Sir John had brought his body of 500 horse, as I noted already, from Oxford to Worcester; the Lord Say, with a strong party, being in the neighbourhood of Oxford, and expected in the town, Colonel Sandys, a hot man, and who had more courage than judgment, advances with about 1500 horse and dragoons, with design to beat Sir John Byron out of Worcester, and take post there for the Parliament.
The king had notice that the Earl of Essex designed for Worcester, and Prince Rupert was ordered to advance with a body of horse and dragoons to face the enemy, and bring off Sir John Byron. This his Majesty did to amuse the Earl of Essex, that he might expect him that way; whereas the king’s design was to get between the Earl of Essex’s army and the city of London; and his Majesty’s end was doubly answered, for he not only drew Essex on to Worcester, where he spent more time than he needed, but he beat the party into the bargain.
I went volunteer in this party, and rode in my father’s regiment; for though we really expected not to see the enemy, yet I was tired with lying still. We came to Worcester just as notice was brought to Sir John Byron, that a party of the enemy was on their march for Worcester, upon which the prince immediately consulting what was to be done, resolves to march the next morning and fight them.
