Service History

  • September: First Battle of Newbury


  • June: Battle of Tipton Green
  • June: Battle of Cropredy Bridge
  • July: Skirmish at Colyton

  • October: Second battle of Newbury
  • November: Relief of Donnington


  • June: Battle of Ilminster
  • June: Battle of Langport


  • February: Battle of Torrington
  • March: Surrender at Truro


Lord Percy was relieved of command at Lostwithiel due to his close association with Lord Wilmot, who was accused of Treason. He later appears to have raised another regiment in the West, Lord Percy’s (Western) Regiment of Horse.


Symonds noted the regiment carried seven red cornets in April 1644.

In June 1643 the regiment was supplied pistol and carbine shot as well as gunpowder. Captain John Messenger was commissioned by Prince Rupert as a captain of cuirassiers in Holtby's regiment. Whether this troop was raised, was equipped with cuirassier armour and joined Percy's regiment is a matter for speculation.

Notable Officers

Lord Percy

Henry Percy, Lord Percy of Alnwick (d. 1659) was younger brother of Algernon, Earl of Northumberland.

Sir Arthur Slingsby

Marmaduke Holtby

Marmaduke Holtby appears to have been Lt Col of the regiment in November 1643 (Rawl. Mss. D 395 f.193/4 24.11.1643) 1). In December 1643 a Captain John Messenger was commissioned by Prince Rupert as a captain of cuirassiers in Holtby's regiment (see below). I know of no further mention of Holtby's regiment so perhaps he failed to raise it. A 'Col. Holtby' was said by a Parliamentary report to have fled by boat from a skirmish at Lancaut in the Forest of Dean in February 1645, uncertain whether the same Holtby.
