A
Macedonian phalanx, as portrayed in the
Rome: Total War computer game. Note that holding the
sarissa with one hand as shown here is essentially impossible;
however, the shield may have been strapped on to the wrist to free
up both hands.
A phalanx (plural phalanxes or phalanges) is a
rectangular mass
formation, usually composed entirely of heavy infantry armed with
spears,
pikes, or similar
weapons.
The phalanx is a hallmark of
Hellenistic or
ancient Greek
warfare;
indeed, the word phalanx is derived from the Greek word phalangos,
meaning finger.
Origins
The earliest know depiction of a phalanx-like formation occurs in a
Sumerian stele. In this particular instance the troops seem to have been
equipped with
spears,
helmets, and large
shields
covering the whole body. Egyptian infantry were also known to have
employed similar formations. However, historians have not arrived at a
consensus regarding the relationship between the Greek formation and
these antecessors; the principles of shield wall and spear hedge were
almost universally known among the armies of major civilizations
throughout history, and as such it is impossible to reject the
possibility that the similarities were due to convergent evolution
instead of actual diffusion.
Some
historians and authorities date the formation of the
hoplite
phalanx of ancient
Greece
to the
eighth century BC in
Sparta,
though this is being revised as it is more likely that the formation was
devised in the
seventh century BC after the introduction of the
Hoplon
shield by the city of
Argos,
after the introduction of which the formation would have been made
possible.
Operation
The
hoplite phalanx was a formation in which the hoplites would line up
in lines, no less than four deep, in very close order. In this
formation, the hoplites would lock their
shields
together, while the first few ranks of soldiers would project their
spears out over the first rank of shields, thus allowing for the first
three or so ranks of spearmen to engage their spears against the enemy.
Therefore, one might say that the phalanx was essentially a formation in
which the hoplites created a mass spear and
shield wall. The effectiveness of the phalanx depended upon how well
the hoplites could maintain this formation while in
combat,
especially when engaged against another phalanx.
When in combat, the whole formation would consistently press forward
trying to break the enemy formation; thus when two phalanx formations
engaged, the struggle essentially became a pushing match, in which, as a
rule, the deeper phalanx would almost always win, with very few recorded
exceptions. At the
Battle of Leuctra (371 B.C.) the Thebans under Epaminondas took this
idea to extremes, thinning out their right and center in order to put a
massive 50-rank deep phalanx on their left. This formation, known as the
oblique phalanx, allowed the Thebans to turn the Spartan right flank
even as the Spartans pushed back the right and center of the Theban
line. The Spartans were defeated, shattering the myth of Sparta's
invicibility in land warfare.
The
Macedonian phalanx is an important variant of the basic Greek
formation. Based on the reforms of
Iphicrates and
Epaminondas, the soldiers in this new phalanx (phalangites)
carried long pikes called
sarissa
that were more than twice as long as the hoplites'
xyston;
as these pikes had to be held in two hands, they adopted the smaller
pelte shield instead of the traditional aspis ( better known
in modern times as the hoplon) and strapped it to the forearm,
thereby freeing the left hand to help bear the weight of the pike. Their
longer pikes allowed more ranks to project the heads of their weapons
beyond the front of the formations. At the same time, the weight and
coverage of their armor was lessened in order to reduce the expense of
equipping them.
As a result of these developments both
Philip II of Macedon and his son
Alexander the Great were able to raise an army of competent,
well-drilled infantry at a much lower cost (in terms of both time and
money) than the Greek city-states to the south. Even though the longer
weapons of the Macedonian phalanx also meant that their formation was
less flexible than that of the Greeks, it was not seen as a great
disadvantage since the phalanx was meant to serve only as a part of a
combined-arms force that also included a variety of
skirmishers and
mounted
troops, most notably the
prodromoi scouts and the famous
Companion cavalry. The Macedonian phalanx generally worked to pin
the center of the enemy line while the Companions attacked the flanks
and the light infantry hovered around to cover the phalanx's immediate
flanks and plug any gaps in the line caused by advancing through
difficult terrain.
The natural tendency during battle would be to drift towards the
right side. This is because the individual hoplites carried their
shields on their left arm. Battles were won when the exposed right side
(carrying spears) could overpower the opposing army's left side
(carrying shields).
Demise
While the phalanx formation was formidable, and nearly indestructible
from the front, the formation was very slow when maneuvering, and could
not, of itself, protect its flanks, nor its rear, because it was a
terribly slow moving formation and when once engaged, could not
disengage, or remaneuver itself. Therefore, when the Phalanx was flanked
(attacked from either the left or right side) it was rendered nearly
defenseless. We see this at the
battle of Pydna in which the
Macedonian phalanx, when engaged against the
Roman infantry, was destroyed once it was outflanked by
cavalry,
simply because it could not defend itself from such an attack.
Another weakness the phalanx faced was light missile troops such as
archers
or
slingers. These troops could stay a safe distance from the phalanx
while at the same time subjecting it to missile fire, thus forcing it to
either
surrender, or
retreat. We see this at the
battle of Lechaeum, where an
Athenian army led by
Iphicrates, consisting of light missile troops armed with
javelins and
bows, succeded in routing an entire Spartan mora (a Spartan
unit numbering anywhere from five to nine hundred hoplites).
It is due to the two above enumerated weakness that after the
Peloponnesian War the phalanx did not perform very well unless included
as part of a combined-arms force. When the phalanx was employed without
cavalry
and/or
light infantry support, it was easy prey to the more flexible
Roman legion, and it went out of fashion after the
battle of Pydna in the year
168 BC,
after which
Macedonia
and Hellas
were made
Roman provinces. Some legends (with little to no historical support)
state that a
Spartan
phalanx drove off marauding
Visigoths after the
Battle of Adrianople.
Revival
The phalanx never quite died out; it formed an important part of the
skoutatoi formations in the later phases of the
Eastern Roman Empire, and later on it enjoyed a major revival in the
form of the Scottish
Schiltron and
Swiss
pike square (see also
Landsknecht). The Swiss phalanx was a much narrower formation than
the hoplite phalanx, usually no more than 20 or 30 men wide but
considerably deeper. The Swiss phalanx had great success - particularly
against
French
cavalry
- for almost a half century, but their ascendancy came to an end with
the Swiss defeat in the
battle of Marignano. It was replaced by the
Spanish
tercio,
which combined the solidity of the phalanx with the flexibility and
firepower of attached
musket
formations.
