Introduction:
Combined arms fighting during the 17TH century, known as “Pike and Shot”, was a bloody and confusing affair. Quickly advancing technology was mixed together with tried-and-true medieval, haphazardly at first, but this quickly formed into competing “systems” on the field of battle. The English authorities recognized the value of standardized drill and in 1623 the Privy Council and Council of War authorized the publication of Instructions for Musters and Arms which became the foundation for the training of the county militias and inevitably found its way into the trained bands in the years leading up to the Civil War. It wasn’t the only publication on warfare to be published in England, not by far. Between 1602 and 1655 no more than 95 military handbooks, drill books, and manuals flew off the London printers, some with entertaining names such as Edward Cooke’s The Perspective Glass of Warre, shewing you a glimpse of Warres Mysteries (1628). Perhaps the most widely used and recognized were the drill books from the Spanish Netherlands, where the leader of the Dutch Revolt, Prince Maurice of Orange, resurrected old Roman tactics and instituted regular training of his soldiers, a practice that had fallen out of fashion during the days of the local militia or trained bands. Jacob de Gheyn’s The Exercise of Arms for Cavaliers, Muskets, and Pikes (1607) was one of the most widely read, and provided the basis for the most common fighting system of the period.
These drill books and manuals reflected the shifting military tactics in Europe at the time. In the first part of this article, we will be studying these new tactics, new armies and new forms of waging war with our lens landing on everything from Sweden to England. It is important to understand these systems, however unknown they may be or irrelevant they may seem, because they feed into the second part of this article – how the Armies of England and Scotland shaped and formed themselves on the eve of the Civil Wars.
The Military Systems of Europe:
The Spanish Tercio
The earliest method of pike and shot warfare, in which soldiers would organize themselves into massive square or rectangle formation, blocks of pikemen in the center with arquebusiers (musketeers) at each corner and entire block. The arquebusiers would fire, and then quickly move into the blocks of pikemen for protection.

The Dutch System
Based upon the Roman “cohort”, Dutch regiments contained the classical number of 550 men each, made up of 250 pikemen and 300 musketeers. Staggered in a “chequerboard” formation, the central pike block were 5 to 10 men deep. The musketeers would form up on the flanks in groups 8 to 12 and perform the “countermarch”. This allowed the front rank to fire, then turn around and allow the next to form up and fire, and so on, providing a constant volley in an era where reloading took some time. The countermarch proved incredibly effective given the proper number of musketeers, trained by the book (literally) to load their weapons quickly. The role of cavalry, in theory, was to provide cover on the flanks. They also performed a maneuver known as the caracole, in which cavalry, like the musketeers, would perform their own version of a countermarch: charging towards the enemy, firing their pistols, and wheeling away to allow the next line of horse to fire, typically in 3 files.

The Swedish System

Formulated by Protestant warrior king Gustavus Adolphus, this system improved on the Dutch System based on Adolphus’ wars against Poland (1626-9) and his time as one of the leading players of the Thirty Years War. Using the same basic infantry tactics as the Dutch, Adolphus instead chose to spread his men thinner, six ranks deep. The fewer ranks allowed for more concentrated firepower. This led to the deadly “Swedish Salvo”, where the rearmost ranks would step up and fill the gaps. One rank would bend down on one knee, the second would crouch, and the third would stand. Firing simultaneously, this massive blast of shot would hopefully hamper the enemy enough to break their formation and allow the infantry and cavalry to charge. Adolphus also abandoned the caracole, adopting a much more aggressive horse tactic, in which the lines would not simply fire off a shot and wheel away, but rather charge into the enemy. The front two ranks would fire their pistols and draw their swords to close in for a melee, while the third rank would charge into the enemy with only swords. The Swedish System also included the use of light field guns able to be maneuvered by small teams during battle. In short, Adolphus took what the Dutch had done and upped the firepower and ruthlessness of the cavalry.

The English Civil War Association Armies
While one side of the conflict had a centralized figure (Charles I) to rally behind and their organization and command structure was very centralized, Parliament had to overcome the exact opposite issue. Essentially, they did have an overall commander of forces, the Earl of Essex, whose leadership and military capabilities were often called into question. Despite this, rather than a single standing army, Parliament formed theirs into “Associations”, the Eastern, Northern, Western, and Southern. Commanders were, of course, noblemen from the House of Lords, including Manchester, Essex, and Waller.
Communication and support between the various Associations was lacking, and since they were all territory based, many troops did not feel comfortable going far from home. Adding to the uncomfortableness of marching so far from their families, the personal ambitions of their social-superior commanders often led to more defeats or missed opportunities.
Such leadership led the more aggressive party (led by Henry Vane and Oliver Cromwell), or the “War Party”, to do away with any more peace talks. They were frustrated with Manchester, spiteful of Essex, and harsh on Waller. They sought a new, professional army, rather than a mix of militia, trained bands, and pressed soldiers serving in separate armies under very different commanders.
The Self-Denying Ordinance:
The War Party’s first step was to introduce a bill to Parliament known as the Self-Denying Ordinance, which forced any member of either House of Parliament to give up their military commissions. The language is as follows:
“Be it Ordained by the Lords and Commons assembled in Parliament, That all and every of the Members of either House of Parliament shall be, and by Authority of this Ordinance are discharged at the end of forty days after the passing of this Ordinance, of and from all and every Office or Command Military or Civil, granted or conferred by both or either of the said Houses of this present Parliament, or by any Authority derived from both or either of them, since the Twentieth day of November, 1640.”
Essentially, this was Parliament “cleaning house”, removing the dead-weight nobles who they accused of purposely dragging out the war, fearful of bringing it to a decisive military conclusion. It also made a clear delineation between who was a politician and who was a soldier. Ironically, one very important MP avoided this Ordinance: Oliver Cromwell. His skills as a cavalry commander in the Eastern Association esteemed him to Parliament, who were more than happy to make an exception and allow him to continue leading his “Ironsides”, the most effective horse Parliament had.
The wording of the Ordinance also helped, as it stated that any MP who was affected by said Ordinance could resume their military position after 40 days, a loophole which both Cromwell and William Brereton exploited to continue their commands, while shaming the prideful Essex & Manchester from asking for their commissions back.
Once the old guard was gone, Parliament got to work on a “New Modelling” of its army. It needed to be professional. It needed to be centralized. It needed officers of experience and skill, not titles. It needed to be properly outfitted and equipped. Most of all, it needed to be ready to bring the war to an end. This was the birth of the New Model Army.
The New Model Army
The “New Model” was placed under the overall command of Sir Thomas Fairfax, who had proved his worth on the field and played no part in politics, making him an ideal choice. He was appointed Commander-in Chief of the army in January 1645. His fellow officers were Philip Skippon (Major-General of Foot), Oliver Cromwell (Lieutenant General of Horse, later second-in-command, eventual Commander-in-Chief), and Thomas Hammond (Lieutenant General of Ordinance).

The New Model was intended to comprise 22,000 men, broken into 12 regiments of foot of 1,200 each, the ratio being 2:1 musketeer to pikemen. 11 regiments of horse comprising 600 men each was also raised, along with 1,00 dragoons, although these in time became regular cavalry. The size of the New Model waxed and waned during the Wars of the Three Kingdoms. At one time the 24 regiments had swelled to nearly 100, at one time boasting a total of nearly 68,000 soldiers.

The army was strictly disciplined, but in turn received something that was rare among the Association armies: regular pay. Pay records show the infantry were paid eight pence per day, while the cavalry received 2 shillings per day. They were also issued matching uniforms, making it easy to recognize friend from foe, a common problem at the time. It was also a meritocracy, in which common soldiers were able to rise through the ranks regardless of class or birth.
Members of the New Model were sometimes pressed into service, though many were religious radicals who truly saw the King as evil. Soldiers were issued Bibles and chaplains were added to every regiment, where the men attended regular prayer meetings. Officers were also put in charge of specific departments, including military justice administration, acquisition of provisions, and Parliament’s great advantage: an effective intelligence network.
The New Model Army was put to its first real test at the Battle of Naseby, where the bulk of King Charles’ army was crushed. This was followed by a string of brilliant victories in Langport and Bristol, and finally Stow-on-the-Wold, effectively bringing an end to the First English Civil War.
Until the Restoration of the Monarchy in 1660, the New Model Army remained a permanent fixture, so much so that it became a political body in and of itself, an instrument with which Cromwell used to further the aims of the Independents (and his own control) over Parliament. Oftentimes, the threat of unleashing the New Model was the only thing keeping the very fragile peace of Cromwell’s “Protectorate” government alive.
Thomas Fairfax gave up his command when Cromwell decided to attack Scotland, who just a few years prior had been Parliament’s greatest ally. The New Model smashed the Scots at Dunbar, then at Worcester in an attempt by the Scots to place Charles’ son on the throne. It saw much service in Ireland, where known atrocities were committed against the Irish Catholic garrison at Drogheda and the bloody sacking of Wexford. It also provided soldiers for expeditions to the West Indies, which included the capture of Jamaica.
Upon the Restoration, King Charles II officially disbanded all units of the New Model Army but one: General George Monck’s regiment, which had marched from Scotland to London in order to bring back the purged Parliament and reestablish the Monarchy. It would be named the Coldstream Guards. This has remained the oldest regiment in continuous service in the British army.
Through proper command structure, drilling & discipline, the New Model Army under Sir Thomas Fairfax paved the way for the order and success of the professional British Army.
And those red coats? You can thank the New Model for that. Venetian red.
