Bury in Lancashire. The "Northern Horse" already had a reputation for hard fighting but poor discipline. There were too many weak regiments of horse and commanders to list separately; also, it is not certain whether any given regiment was present at Marston Moor, or was elsewhere (with a force under Colonel Clavering, or in various garrisons). At Marston Moor, Newcastle's cavalry were organised as: Sir Charles Lucas's Brigade (700) Sir Richard Dacre's Brigade (800) (Dacre was mortally wounded during the battle) Sir William Blakiston's Brigade (600) Sir Edward Widdrington's Brigade (400) Colonel Samuel Tuke's Regiment (200) (formerly the Duke of York's regiment) Colonel Francis Carnaby's Regiment (200) Commissary-General George Porter's Troop (50) Derbyshire contingent When Goring marched to join Rupert in Lancashire, he picked up a contingent from Derbyshire en route. John Frescheville's Regiment of Horse (240) Rowland Eyre's Regiment of Horse (160) Detachments from Frescheville's, Eyre's and John Millward's Regiments of Foot (220) (noted as the "Derbyshire Foot" on De Gomme's plan) Garrison of York (part) (number of horse unknown, 3,000 Foot) General Marquess of Newcastle Lieutenant General Lord Eythin Sir Thomas Metham's "Troop of Gentleman Volunteers" Sergeant-Major General Sir Francis Mackworth As with Goring's horse, Newcastle's infantry were from too many weak regiments to list separately. On the battlefield they were formed into seven "divisions". Newcastle's army was mostly raised in Northumberland and Durham and had already endured a siege of ten weeks, with some hard fighting. Three other regiments (of Sir Thomas Glemham, Sir John Belasyse and Sir Henry Slingsby), totalling 1000 men, were left to hold York. References Notes Printed Sources Orders of battle
