Pike & Shot Warfare – the 17th Century Military Revolution

The Early Modern period was one of great change, not least in military theory and practice. The battle of Edgehill was to witness a clash of the two latest military doctrines in 1642. Many English, Scottish, Irish and Welsh fought in the endless Wars of Religion, Eighty Years War and Thirty Years War in Europe. They brought both doctrines back to England.

The 17th Century saw a military revolution that dominated warfare for the next two and half centuries. Until their defeat at the Battle of Rocroi in 1643, the Spanish imperial tercios were feared as the finest infantry in Europe. However, smaller linear formations of pike and musket – Pike and Shot – progressively replaced these great squares of pike, shot, sword and buckler.

Spanish Tercios – piqueroscoseletes, arquebusier & musketeers

The Spanish word ‘tercio’ translates as ‘one third’. Initially, these huge formations were made up of one third of the foot soldiers within a Spanish army. By the 17th Century, their number had grown so that many tercios might be deployed within an army.

In theory, each tercio had a strength of 3,000. In practice, years of hard campaigning reduced their numbers to 1-2,000. The tercio consisted of ten companies each of 150 pikemen, 100 arquebusier and 40 ‘coseletes’ armed with sword and buckler. These were deployed in a single great square block, ‘bastioned’ with smaller blocks at each corner.

The central square ‘cuadro’ consisted of pikemen, 22 ranks deep. Ideally, this block had a frontage of 56 files. Arquebusier and men with sword and buckler lined the square. More arquebusier formed the bastions, or ‘mangas’ (sleeves) at its corners. Each manga consisted of 240 men. Finally, each tercio could deploy two skirmish lines, each of 90 musketeers.

Although slow and difficult to manoeuvre, the tercios great depth brought all-round defence. They were impossible to outflank. They also delivered an almost unstoppable momentum in an attack. However, their weakness lay in the limited firepower they could bring to bear to their fronts. This was to be increasingly exploited by their enemies.

17th Century Military Formations & Tactics

Inspired by classical Roman tactics, the Dutch reforms of Prince Maurice of Nassau brought greater firepower to bear and strength in defence. This saw a return to linear formations.

King Gustavus II Adolphus of Sweden adapted these tactics further to deliver both firepower and offensive mobility. These two military doctrines were to clash on the field of Edgehill.

Pike & Shot Companies – files & divisions

Both the Dutch and Swedish models of Pike and Shot warfare were based around groupings of file, division (section), company, battalion and regiment; organisational structures that persist today in the British Army. At its most basic level, men formed files; one man standing behind another.

A Dutch file consisted of eight men, one behind another in 8 ranks. This depth was designed to withstand a charge of pikes and allow continuous volley fire as each rank of musketeers fired and reloaded. The Swedish model of six ranks only was to be adopted by all as the British Civil Wars progressed. This reflected both a lack of manpower and growing professionalism.

Files were grouped under a corporal to form a division (a section today) of either pikemen or musketeers. In practice, the number of files depended on manning. However, 4 files per division was the ideal. The corporal led his right-hand file, with his lansprizado (lance-corporal) leading the left-hand file.

A standard foot company consisted of one pike and two musketeer divisions. It was a mixed grouping capable of independent operations. In theory, a captain’s company comprised 100 rank and file; 32 pikemen and 64 musketeers (including corporals), 2 drummers, a clerk and an armourer. In practice, most parliamentary companies at Edgehill were closer to 70-80.

Early Modern Regiments – battalions, pike blocks & plotoons

As today, each foot regiment consisted of a number of companies (generally ten in 1642). The regimental colonel, lieutenant-colonel and major each nominally commanded their own (slightly larger) companies. Captains commanded the remaining companies. Company officers consisted of a lieutenant, an ensign (who carried the company colour with the pikes) and two sergeants (responsible for musket drill).

Although part of a regiment, individual captains held commissions to recruit, equip and maintain their companies. They had to bear the financial risk when pay from king or parliament was inevitably in arrears. In some cases, they were still referred to as private companies. This is key to understanding the apparent ill-discipline of the time, when troops were unpaid and hungry.

On the battlefield, companies grouped together to form a battaile or battalion. The pike divisions massed to form a single stand or block of pikes. The two musketeer divisions of a company formed a plotoon. These deployed to form two wings of shot that normally flanked the pike block.

Pike and Shot warfare theory allowed a fully manned foot regiment to field two battalions. In practice, regiments rarely had the strength to form more than one. Increasingly, as the war progressed, regiments had to be combined to form a single battalion. The minimum strength of a battalion seems to have been about 400, the ideal 600.

Sergeant-Majors, Sergeants & Camp Followers

Each company and regiment needed a cadre of experienced soldiers that could mould others into a fighting force. As today, they relied upon their sergeants to do this. Within each company, two sergeants were employed to train, drill and direct the musketeer divisions.

At the regimental level, a professional soldier was employed as the sergeant-major. This officer was responsible for much of the day-to-day training, operating and security of the regiment. He did this through his company sergeants. Above the sergeant-major, a sergeant-major-general oversaw these functions across the foot regiments of an army. As the 17th Century progressed, the titles of these officers became shortened to major and major-general. These ranks remain today in the British Army.

Invariably, a significant number of non-combatant followers accompanied every company. These were generally women and boys, often wives and sons, as well as prostitutes and orphans. Nehemiah Wharton writes of ‘our knapsack boys’. It is not clear how many boys followed each company during the British Civil Wars. However, the Spanish expected one boy per file.

The Battle of Edgehill – Dutch Tertias & Swedish Brigades

At Edgehill, the parliamentary foot battalions deployed in three Dutch style tertias (thirds). Each tertia consisted of four battalions; one forward, two in second line and a fourth in reserve. The three tertias of a Dutch army deployed in line, vanguard (right), main (middle) and rear-guard (left). Like the Roman quincunx, these formed a checkerboard of battalions in three offset lines.

Prince Rupert had studied Gustavus’ tactics. Under his influence, the King’s foot deployed in 5 (smaller) Swedish style brigades. These also consisted of four battalions in diamond formation. However, these battalions were considerably smaller than those of Essex’s army. De Gomme’s map of the royalist deployment shows the King’s foot clearly, in tighter offensive (attack) formation. The fourth pike blocks have closed up and the musketeer wings have dropped back, in reserve.

English Civil War Horse Troops, Squadrons & Regiments

As was normal for the period, at Edgehill, brigades of horse deployed on the flanks of each army. De Gomme shows the King’s horse drawn up in two lines of squadrons, each of two to three troops. The parliamentary horse seem to have operated as individual troops. On their left flank plotoons of musketeers deployed between troops of horse.

In theory, a troop of horse consisted of 72 rank and file (69 troopers and 3 corporals). These made up three divisions, under a captain, a lieutenant and a cornet. However, numbers were often in the mid-forties. The files of an English horse troop were, in theory, six deep. However, civil war troops generally drew up in half files of three deep for battle. The order of precedence between the ranks was: 1, 3, 2.

Divided Kingdom – English Civil War historical fiction

These historical notes accompany the text of the English Civil War historical fiction series Divided Kingdom. The novel God’s Vindictive Wrath opens at the Battle of Edgehill and ends with the Battle of Turnham Green in 1642. Desecration is a short story during the Storming of Winchester and the desecration of Europe’s greatest medieval cathedral. The Keys of Hell and Death covers the war in the west, from the Battle of Lansdown Hill to the Storming of Bristol in 1643.

The Divided Kingdom books take a fresh approach. They are not based on a single hero. They do not take sides. Their voices – ordinary men and women – face each other in the chaos of Britain in civil war. They are both relatable and sharply relevant today. They are also as historically accurate as is possible.
