Parliamentarian regiment of foot raised for the Earl of Essex’s army
The regiment seems to have missed the battle of Edgehill although a number of its officers were certainly present. Peterborough himself as General of the Ordnance, his Lt-Col commanding a troop of Horse (and defecting to the Royalists) and Capt John Botteler/Butler who claimed to have had his original commission destroyed at the battle. The regiment surrendered at Banbury a few days later, surrendering its arms but being allowed to march away. The regiment was re-founded in November with most of the same company commanders, but with a new levy of 600 men. This was made up to 800 at the beginning of December. Peterborough died in June and the regiment was disbanded shortly afterwards.
Peterborough's regiment were issued with coats of an unknown colour in September. Following the reformation of the regiment they were reissued with red coats with blue lining in November 1642 1). The reformed regiment were armed with firelocks.
