Sarissa
The sarissa or sarisa was a 4 to 7 meter long spear used in the ancient Greek and Hellenistic warfare. It was introduced by Philip II of Macedon and was used in the traditional Greek phalanx formation as a replacement for the earlier dory, which was considerably shorter. The phalanxes of Philip...

The Middle Ages

In the early Middle Ages, infantry used the shieldwall, a formation where shields were held edge-to-edge or overlapped. Close order was routinely used by infantry in the later Middle Ages, the intention being to avoid the enemy penetrating and disrupting their formation. A common literary image was that an apple should not be able to pass between their lances.

The sixteenth century

The period 1490-1520 saw the emergence of a consensus in military thinking that armies should be increasingly ordered on the battlefield and that neat, rectalinear formations were the key to this. The uniform bodies of pikes would be ordered based on an area occupied by a soldier of three paces frontage and seven paces depth, the soldier being positioned at the centre of this rectangle. Pikes did not stand alone on the battlefield, however, and new formations of horns or sleeves of shot were developed to support these pikeblocks with firearms. At the end of the 16th. century, a system called countermarching was developed, which enabled an exchange of ranks of shooters. This led to the development of thinner formations and set tactitians on the road to developing the linear fire tactics of the 18th. century.

On horseback, the old knightly tactics slowly gave way to new tactics involving firearms and these led to the development of pistol-armed cavalry known as reiters. Reiters specialised in manoeuvering in deep, close formations and practiced a tactic known as the caracole

17th and 18th centuries

In the 17th century European armies expanded their use of firearms, which were at first matchlock
Matchlock
The matchlock was the first mechanism, or "lock" invented to facilitate the firing of a hand-held firearm. This design removed the need to lower by hand a lit match into the weapon's flash pan and made it possible to have both hands free to keep a firm grip on the weapon at the moment of firing,...

 attacks as rifling technology, which significantly increased the range and accuracy of firearms (at the expense of a substantially reduced rate of fire), began to see increased use in the late 18th century. Fortifications were designed to break up formations (reducing the effectiveness of volley fire), or to expose them to enfilading
Enfilade and defilade
Enfilade and defilade are concepts in military tactics used to describe a military formation's exposure to enemy fire. A formation or position is "in enfilade" if weapons fire can be directed along its longest axis. A unit or position is "in defilade" if it uses natural or artificial obstacles to...

 in the center, along with reserve forces. This formation enabled the defenders to fire on cavalry on all sides of the formation, although there was some risk that fire from one square might reach other squares formed nearby. The effectiveness of a square depended on the ability of the infantry to hold their ground against cavalry charges.

The eclipse of close-order formations

During the 19th century, advances in firearms technology rendered the use of close formations obsolete. Widespread use of rifled guns (including cannons), and the advent of reliable breech-loading weapon

, altered the tactical landscape. These weapons fired at greater range with accuracy, and technological improvements in aiming them also simplified the targeting of large bodies of enemy forces.
