The pezhetairoi (Greek: πεζέταιροι, singular: pezhetairos) were the backbone of the Macedonian army and Diadochi kingdoms. They were literally "foot companions" (in Greek, pezos means "foot warrior" or "infantryman", and hetairos means "companion" or "friend").
The Macedonian phalanxes were made up almost entirely of pezhetairoi. Pezhetairoi were very effective against both enemy cavalry and infantry, as their long pikes could be used to impale enemies charging on horse-back or to keep enemy infantry with shorter weapons at bay.
The pezhetairoi were the battalions of the Macedonian phalanx. They first came to prominence during the reign of Philip II, particularly when they played such an important role in Philip's subjugation of Greece at the Battle of Chaeronea in 338 BCE. The name "foot companions" was used by famed commander Alexander the Great, the successor of Phillip II, as an ancient recruiting method. By labeling his infantry as his personal "companions" and "friends," Alexander was able to engage a wider manpower base for his subsequent military campaigns, as positions in his personal infantry would denote pride and honor. Therefore, as Alexander would campaign across Asia, he was able to use his reputation as a brilliant military strategist, along with the personal connotation given to his infantry, to recruit more native peoples to his cause than conventional recruitment methods of the day. This created a near endless base of manpower for the burgeoning military leader, and allowed him to engage in longer, costlier campaigns in areas like Asia Minor, Egypt, Persia, and India.
They were armed with the sarissa, a long spear with a shaft made from flexible cornel wood, which had a much longer reach than the traditional hoplite spear. Because of its length the phalanx could present the spearpoints of around five files of men; which made the phalanx almost impenetrable, and fearsome to oppose.
Tactically, the pezhetairoi were best used as a strong defensive line, rather than as shock troops. The length of the sarissa, while making them terrifying for an enemy to oppose, severely limited their maneuverability; and if they were taken in flank or rear they had little chance of responding. This was particularly clear at the Battle of Gaugamela in 331 BCE, when the rapid advance of the right wing caused a breach to open between two of the battalions of pezhetairoi—a force of enemy cavalry broke through and, had it not been for a lack of discipline in their own command, and for Alexander's placing of a second line of traditional hoplites in reserve, the phalanx might have been destroyed from the rear.
Apart from in pitched battles, the pezhetairoi and their sarissas were not very practical; it is supposed that they were re-armed, and their tactics adapted, to suit the guerrilla warfare that was prevalent, and necessary, in Bactria and Sogdia.
dubious The Asthetairoi (singular Asthetairos) were the elite of the Macedonian Infantry. They were chosen Foot Companions, equipped with sarissa (21 feet long pike), argive shield, and short sword. They had mail-plate and bronze helmet. The Asthetairoi were the elite bodyguards of the Macedonian kings.
The battalions of pezhetairoi appear to have been organised on a regional basis, at least to begin with. We know of battalions named for the regions of Orestis/Lyncestis (two battalions probably combining men from both regions), Elimaea and Tymphaea—if all pezhetairoi were from Upper Macedonia then we would expect the other battalions to have represented Eordaea and Pelagonia. In 334 BCE Alexander the Great took six battalions of pezhetairoi with him to Asia. By the time the army moved into India in 327 BC, a seventh battalion had been added.
- At the Battle of the Granicus the battalions were those of (from right to left): Perdiccas, Coenus, Amyntas, Philip, Meleager, and Craterus.1
- At the Battle of Issus the battalions were those of (from right to left): Coenus, Perdiccas, Craterus, Meleager, Ptolemy (replacing Philip), Amyntas.2
- At the Battle of Gaugamela the battalions were those of (from right to left): Coenus, Perdiccas, Meleager, Polyperchon (replacing Ptolemy), Simmias (deputising for Amyntas, who was recruiting in Macedonia), Craterus.3
- At the Battle of the Hydaspes River only five battalions took part, and were those of (from right to left): Antigenes, Clitus the White, Meleager, Attalus, Gorgias. The other battalions (those of Polyperchon and Alcetas) remained on the western bank of the Hydaspes, under the command of Craterus, and crossed only when Alexander was victorious, in order to continue with the pursuit of the fleeing Indians. However, there is much supposition and guesswork regarding this battle.4
