Later Colonel James Berry’s, Unton Croke’s and Daniel O’Neill’s Regiment of Horse
Commonwealth regiment of horse serving in Scotland, later defeating Penruddock’s Rising in the West Country
A history of the regiment is given in The Regimental History of Cromwell's Army by Sir Charles Firth and Godfrey Davies, Clarendon Press, Oxford, 1940.
The regiment was raised in the North by Hesilrigge, but his colonelcy appears nominal as it was quickly sent to Scotland led by Major Sanderson, who died in February 1651, then by Major John Sydenham who was mortally wounded in a skirmish at Linlithgow. They served initially as garrison of Linlithgow, then in the West of Scotland with Okey, and remained as part of Monck’s force.
In 1655 Captain Unton Croke was instrumental in ending Penruddock’s Rising, defeating Penruddock’s 250 to 400 Royalists at South Molton with a single troop. In 1660 Croke was promoted to Colonel but was soon replaced by Dan O’Neill before the regiment was disbanded at Bath in December.
Sir Arthur Heslirigge raised the regiment but never served with them on campaign.
Daniel O’Neill was an officer of Prince Rupert’s Regiment of Horse in the First Civil War.
