Skirmisher

Last updated February 25, 2024

Skirmishers are light infantry or light cavalry soldiers deployed as a vanguard, flank guard or rearguard to screen a tactical position or a larger body of friendly troops from enemy advances. They are usually deployed in a skirmish line, an irregular open formation that is much more spread out in depth and in breadth than a traditional line formation. Their purpose is to harass the enemy by engaging them in only light or sporadic combat to delay their movement, disrupt their attack, or weaken their morale. Such tactics are collectively called skirmishing.

Skirmishers can be either regular army units that are temporarily detached to perform skirmishing or specialty units that are specifically armed and trained for such low-level irregular warfare tactics. Light infantry, light cavalry, and irregular units often specialize in skirmishing. Skirmishers' open formations and smaller numbers can give them superior mobility over the regular forces, allowing them to engage only on favorable terms, taking advantage of better position or terrain, and quickly withdrawing from any threat of superior enemy forces.

Though often critical in protecting the main army from sudden enemy advances, skirmishers are poor at taking or defending ground from heavy infantry or heavy cavalry. In modern times, following the obsolescence of such heavy troops, all infantry has become indistinguishable from skirmishers, and the term has effectively lost its original military meaning as a distinct class of soldier, although skirmishing as a combat role is commonplace.

Ancient history

In ancient warfare, skirmishers typically carried bows, javelins, slings and sometimes light shields. Acting as light infantry with their light arms and minimal armour, they could run ahead of the main battle line; release a volley of arrows, sling stones, or javelins; and retreat behind their main battle line before the clash of the opposing main forces. The aims of skirmishing were to disrupt enemy formations by causing casualties before the main battle and to tempt the opposing infantry into attacking prematurely, thus throwing their organization into disarray. Skirmishers could also be effectively used to surround opposing soldiers in the absence of friendly cavalry.

Once preliminary skirmishing was over, skirmishers participated in the main battle by shooting into the enemy formation, or they joined in melée combat with daggers or short swords. Their mobility made skirmishers also valuable for reconnaissance, especially in wooded or urban areas.

In Classical Greece, skirmishers originally had a low status. For example, Herodotus, in his account of the Battle of Plataea of 479 BC, mentioned that the Spartan Army fielded 35,000 lightly armed helots to 5,000 hoplites, but there is no mention of them in his account of the fighting.^[1] Often, Greek historians ignored them altogether,^[1] but Xenophon distinguished them explicitly from the statary troops.^[2] It was far cheaper to equip oneself as lightly armed than a fully-armed hoplite. Indeed, it was common for the lightly armed to go into battle equipped with stones.^[3] The low status of skirmishers reflected the low status of the poorer sections of society that made up skirmishers.^[4] Additionally, hit-and-run tactics went against the Greek ideal of heroism. Plato gives the skirmisher a voice to advocate "flight without shame" but only to denounce it as an inversion of decent values.^[5]

Nevertheless, skirmishers then chalked up significant victories, such as the Athenian defeat at the hands of the Aetolian javelin men in 426 BC and, during the same war, the Athenian victory at the Battle of Sphacteria.^[4]

Skirmisher infantry gained more respect in subsequent years, as their usefulness was more widely recognised and as the ancient bias against them waned. Peltasts, light javelin infantry, played a vital role in the Peloponnesian War, and well-equipped skirmisher troops such as thureophoroi and thorakites would be developed to provide a strong mobile force for the Greek and the Macedonian armies.

The Celts did not, in general, favour ranged weapons. The exceptions tended not to include the use of skirmishers. The Britons used the sling and javelin extensively but for siege warfare, not skirmishing.^[6] Among the Gauls, likewise, the bow was employed to defend a fixed position.^[7] The Celts' lack of skirmishers cost them dearly during the Gallic Invasion of Greece of 279 BC when they found themselves helpless in the face of Aetolian skirmishing tactics.^[8] Thracians were famous for their skirmish war tactics and offered their services as mercenaries more than once in the Greek civil wars in ancient times.^[9]

In the Punic Wars, despite the Roman and Carthaginian armies' different organisations, both had the role for skirmishers as screening the main armies.^[10] The Roman legions had a specialised infantry class, Velites, which acted as skirmish troops who engaged the enemy before the Roman heavy infantry made contact, and the Carthaginians recruited their skirmishers from the native peoples across the Carthaginian Empire.

The Roman army of the late republican and early imperial periods frequently recruited foreign auxiliary troops to act as skirmishers to supplement the citizen legions.

Middle Ages

Medieval skirmishers were generally commoners armed with crossbows or longbows. In the 14th century, although long held in disdain by the aristocratic Castilian heavy cavalry, the crossbowmen contributed greatly to the Portuguese victory at the Battle of Aljubarrota. Similarly, English archers played a key role in the English victory over French heavy cavalry at the Battle of Crécy. In the next century, they largely repeated that feat at the Battle of Agincourt. Such disasters have been seen as marking the beginning of the end of the dominance of medieval cavalry in general and of the heavy cavalry in particular.

Early modern period

Americas

The Seven Years' War and American Revolutionary War were two early conflicts in which the modern rifle began to make a significant contribution to warfare. Despite its lower rate of fire, its accuracy at long range offered advantages over the smoothbore musket, then commonly used by regular armies. In both wars, many American frontiersmen served in the militia. The Continental Army during the American Revolutionary War was assisted by such irregular troops, such as the Minutemen, who engaged in skirmishing tactics by firing from cover, rather than in the open-field engagements that were customary at the time. Their tactics were influenced by experiences in fighting Native Americans. Militia in a skirmish role was particularly effective in the Battle of Cowpens. The character of Natty Bumppo in James Fenimore Cooper's novel The Last of the Mohicans was notably called La Longue Carabine by the French because of his skill with the long rifle, which was common among the Colonials.

Napoleonic Wars

During the Napoleonic Wars, skirmishers played a key role in battles; they attempted to disrupt the main enemy force by firing into their close-packed ranks and to prevent enemy skirmishers from doing the same to friendly troops. Because skirmishers generally fought in open order, they could take cover behind trees, houses, towers and similar items, thereby presenting unrewarding targets for small arms and artillery fire. Such tactics often made them vulnerable to cavalry. Some skirmishers had a minor sapper role by placing cheval de frise to deter cavalry.

A skirmish force screening the main body of infantry became so important to any army in the field that eventually, all major European powers developed specialised skirmishing infantry. Examples included the German Jäger , the French voltigeurs and the British riflemen.

Muskets were the predominant infantry weapon of the late 18th century, but the British Army learned firsthand of the importance of rifles during the American Revolutionary War and began experimenting with them shortly thereafter, resulting in the Baker rifle. Although slower to reload and more costly to produce than a musket, it was much more accurate and proved its worth during the Peninsular War. Throughout the conflict, British riflemen could selectively target and eliminate the officers and NCOs of French forces from outside musket range.^[11]

During the War of 1812, American riflemen again contributed to British casualties but also had to contend with the revised British light infantry tactics.

A consequence of those wars' experiences was a trend to training line troops to adopt tactics that had been used only by skirmishers.^[12]

American Civil War

The treatise New American Tactics, by General John Watts de Peyster, advocated making the skirmish line the new line of battle, which was then a revolutionary idea.^[13] During the American Civil War, cavalrymen often dismounted and formed a skirmish line to delay enemy troops who were advancing toward an objective. An example was the action of the Union cavalrymen led by Brigadier General John Buford on the first day of the Battle of Gettysburg. Skirmish lines were also used to harass enemy probing missions, hampering the other force from gaining an effective intelligence picture by engaging their scouts, and likewise forcing them to deploy.^[14]

Late modern period

By the late 19th century, the concept of fighting in formation was on the wane. Heavy infantry had disappeared, and all infantry effectively became skirmishers. The term has become obsolete, but as late as World War I, it continued to be associated with battlefield reconnaissance screens, which are essentially modern skirmish lines. As in the American Civil War, the primary role of the infantry skirmish line was to screen the advance of a parent force and to disrupt the enemy's own reconnaissance efforts.^[15] With the mechanization of modern warfare, the role of infantry skirmishers was more or less combined with those of light cavalry, as mounted scouts in specialized reconnaissance vehicles took over the responsibility of screening large formations during maneuvers, in addition to conducting their own probing actions.^[16]

Cold War and beyond

Some modern military units still use light and heavily armed units in conjunction. For example, the Soviet Army routinely deployed more lightly armed motorized rifle regiments as skirmishers on the flanks or secondary sectors of a motorized rifle division on the offensive, and the heaviest units, backed by the heaviest armour, would fight in the division's main effort. The modern US military has light rapid-deployment Stryker brigade combat teams working with heavy-mechanized and armored units, with tracked M2 Bradley infantry fighting vehicles and M1 Abrams tanks forming the primary combat force.

Apartheid South Africa's military doctrine stressed the use of highly-mobile, light-mechanized forces that could cover ground swiftly while they kept heavier enemy armoured and infantry formations off balance and did not engage until the conditions were favourable.^[17] The lightly armed South African units used tactics such as rapid movement, flank harassment and confusing the enemy with continuous maneuvering to compensate for their inferiority in firepower when they were faced with Angolan and Cuban forces during the South African Border War.^[17] The innovative use of South African reconnaissance units to throw Angolan tank formations into disarray before it lured them into ambushes, effectively deploying the units as skirmishers, was another consistent feature of that conflict.^[18]

Historically, cavalry are soldiers or warriors who fight mounted on horseback. Cavalry were the most mobile of the combat arms, operating as light cavalry in the roles of reconnaissance, screening, and skirmishing in many armies, or as heavy cavalry for decisive shock attacks in other armies. An individual soldier in the cavalry is known by a number of designations depending on era and tactics, such as a cavalryman, horseman, trooper, cataphract, knight, drabant, hussar, uhlan, mamluk, cuirassier, lancer, dragoon, or horse archer. The designation of cavalry was not usually given to any military forces that used other animals for mounts, such as camels or elephants. Infantry who moved on horseback, but dismounted to fight on foot, were known in the early 17th to the early 18th century as dragoons, a class of mounted infantry which in most armies later evolved into standard cavalry while retaining their historic designation.

Infantry is a specialization of military personnel who engage in ground combat on foot. Infantry generally consists of light infantry, irregular infantry, heavy infantry, mountain infantry, motorized infantry, mechanized infantry, airborne infantry, air assault infantry, and naval infantry. Other types of infantry, such as line infantry and mounted infantry, were once commonplace but fell out of favor in the 1800s with the invention of more accurate and powerful weapons.

Military tactics encompasses the art of organizing and employing fighting forces on or near the battlefield. They involve the application of four battlefield functions which are closely related – kinetic or firepower, mobility, protection or security, and shock action. Tactics are a separate function from command and control and logistics. In contemporary military science, tactics are the lowest of three levels of warfighting, the higher levels being the strategic and operational levels. Throughout history, there has been a shifting balance between the four tactical functions, generally based on the application of military technology, which has led to one or more of the tactical functions being dominant for a period of time, usually accompanied by the dominance of an associated fighting arm deployed on the battlefield, such as infantry, artillery, cavalry or tanks.

Combined arms is an approach to warfare that seeks to integrate different combat arms of a military to achieve mutually complementary effects—for example, using infantry and armour in an urban environment in which each supports the other.

Light infantry refers to certain types of lightly-equipped infantry throughout history. They have a more mobile or fluid function than other types of infantry, such as heavy infantry or line infantry. Historically, light infantry often fought as scouts, raiders, and skirmishers. These are loose formations that fight ahead of the main army to harass, delay, disrupt supply lines, engage the enemy's own skirmishing forces, and generally "soften up" an enemy before the main battle. Light infantrymen were also often responsible for screening the main body of a military formation.

<i>Peltast</i> Type of ancient Greek light infantry

A peltast was a type of light infantry originating in Thrace and Paeonia and named after the kind of shield he carried. Thucydides mentions the Thracian peltasts, while Xenophon in the Anabasis distinguishes the Thracian and Greek peltast troops.

Shock troops or assault troops are formations created to lead an attack. They are often better trained and equipped than other infantry and expected to take heavy casualties even in successful operations.

Light cavalry comprised lightly armed and armored cavalry troops mounted on fast horses, as opposed to heavy cavalry, where the mounted riders were heavily armored. The purpose of light cavalry was primarily raiding, reconnaissance, screening, skirmishing, patrolling, and tactical communications. Prior to the 17th century they were usually armed with swords, spears, javelins, or bows, and later on with sabres, pistols, shotguns, or carbines.

Line infantry was the type of infantry that composed the basis of European land armies from the mid-17th century to the mid-19th century. Maurice of Nassau and Gustavus Adolphus are generally regarded as its pioneers, while Turenne and Montecuccoli are closely associated with the post-1648 development of linear infantry tactics. For both battle and parade drill, it consisted of two to four ranks of foot soldiers drawn up side by side in rigid alignment, and thereby maximizing the effect of their firepower. By extension, the term came to be applied to the regular regiments "of the line" as opposed to light infantry, skirmishers, militia, support personnel, plus some other special categories of infantry not focused on heavy front line combat.

The army of the Kingdom of Macedon was among the greatest military forces of the ancient world. It was created and made formidable by King Philip II of Macedon; previously the army of Macedon had been of little account in the politics of the Greek world, and Macedonia had been regarded as a second-rate power.

Infantry tactics are the combination of military concepts and methods used by infantry to achieve tactical objectives during combat. The role of the infantry on the battlefield is, typically, to close with and engage the enemy, and hold territorial objectives; infantry tactics are the means by which this is achieved. Infantry commonly makes up the largest proportion of an army's fighting strength, and consequently often suffers the heaviest casualties. Throughout history, infantrymen have sought to minimise their losses in both attack and defence through effective tactics.

The Coalition forces of the Napoleonic Wars were composed of Napoleon Bonaparte's enemies: the United Kingdom, the Austrian Empire, Kingdom of Prussia, Kingdom of Spain, Kingdom of Naples, Kingdom of Sicily, Kingdom of Sardinia, Dutch Republic, Russian Empire, the Ottoman Empire, Kingdom of Portugal, Kingdom of Sweden, and various German and Italian states at differing times in the wars. At their height, the Coalition could field formidable combined forces of about 1,740,000 strong. This outnumbered the 1.1 million French soldiers. The breakdown of the more active armies are: Austria, 570,000; Britain, 250,000; Prussia, 300,000; and Russia, 600,000.

For much of history, humans have used some form of cavalry for war and, as a result, cavalry tactics have evolved over time. Tactically, the main advantages of cavalry over infantry were greater mobility, a larger impact, and a higher riding position.

<span class="mw-page-title-main">Javelin</span> Type of light spear designed to be thrown by hand

A javelin is a light spear designed primarily to be thrown, historically as a ranged weapon. Today, the javelin is predominantly used for sporting purposes such as the Javelin throw. The javelin is nearly always thrown by hand, unlike the sling, bow, and crossbow, which launch projectiles with the aid of a hand-held mechanism. However, devices do exist to assist the javelin thrower in achieving greater distances, such as spear-throwers or the amentum.

Heavy infantry consisted of heavily armed and armoured infantrymen who were trained to mount frontal assaults and/or anchor the defensive center of a battle line. This differentiated them from light infantry who are relatively mobile and lightly armoured skirmisher troops intended for screening, scouting, and other tactical roles unsuited to soldiers carrying heavier loads. Heavy infantry typically made use of dense battlefield formations, such as shield wall or phalanx, multiplying their effective weight of arms with force concentration.

The Hellenistic armies is a term which refers to the various armies of the successor kingdoms to the Hellenistic period, emerging soon after the death of Alexander the Great in 323 BCE, when the Macedonian empire was split between his successors, known as the Diadochi.

In Ancient Greek armies, the psiloi were the light infantry who usually acted as skirmishers and missile troops, and who were distinguished from the armored hoplitai by their light weapons and lack of armor.

The types of military forces in the Napoleonic Wars represented the unique tactical use of distinct military units, or their origin within different European regions. By and large the military forces during the period had not changed significantly from those of the 18th century, although their employment would differ significantly.

The Praecepta Militaria is the Latin conventional title given to a Byzantine military treatise, written in ca. 965 by or on behalf of Eastern Roman emperor Nikephoros Phokas. Its Greek title is Στρατηγικὴ ἔκθεσις καὶ σύνταξις Νικηφόρου δεσπότου Strategikè ékthesis kaì syntaxis Nikephórou despótou.

Although the term infantry dates from the 15th century, the foot troops of the previous eras in history who fought with a variety of weapons before the introduction of the firearms are also referred to as infantry. During the Ancient and Middle Ages infantry were often categorized by the types of weapons and armour they used, such as heavy infantry and light infantry. Generally, light infantry acted as skirmishers, scouts, and as a screening force for the more heavily armed and armored heavy infantry, the latter of which often made up the bulk of many historic armies.
