The scythed chariot was a war chariot with scythe-like blades mounted on each side, employed in ancient times.
The scythed chariot was a modified war chariot. The blades extended horizontally for about 1 meter (3 ft) to each side of the wheels. The Greek general Xenophon (430−354 BC), an eyewitness at the battle of Cunaxa, tells of them: “These had thin scythes extending at an angle from the axles and also under the driver’s seat, turned toward the ground”.
Dismissing completely 17th to 19th century ideas of a Canaanite, Assyrian, Indian or Macedonian origin, Nefiodkin also challenges Xenophon’s attribution of scythed chariots to the first Persian king Cyrus, pointing to their notable absence in the invasion of Greece (480−479 BC) by one of his successors, Xerxes I. Instead, he argues that the Persians introduced scythed chariots sometime later during the Greco-Persian Wars, between 467 BC and 458 BC, as a response to their experience fighting against Greek heavy infantry.
The scythed chariot was pulled by a team of four horses and manned by a crew of up to three men, one driver and two warriors. Theoretically the scythed chariot would plow through infantry lines, cutting combatants in half or at least opening gaps in the line which could be exploited. It was difficult to get horses to charge into the tight phalanx formation of the Greek/Macedonian hoplites (infantry). The scythed chariot avoided this inherent problem for cavalry, by the scythe cutting into the formation, even when the horses avoided the men. A disciplined army could diverge as the chariot approached, and then re-form quickly behind it, allowing the chariot to pass without causing many casualties. War chariots had limited military capabilities. They were strictly an offensive weapon and were best suited against infantry in open flat country where the charioteers had room to maneuver. At a time when cavalry were without stirrups, and probably had neither spurs nor an effective saddle, though they certainly had saddle blankets, scythed chariots added weight to a cavalry attack on infantry. Historical sources come from the infantry side of such engagements i.e. the Greek and Roman side. Here is one recorded encounter where scythed chariots were on the winning side:
The soldiers had got into the habit of collecting their supplies carelessly and without taking precautions. There was one occasion when Pharnabazus[disambiguation needed ], with 2 scythed chariots and about 400 cavalry, came on them when they were scattered all over the plain. When the Greeks saw him bearing down on them, they ran to join up with each other, about 700 altogether; but Pharnabazus[disambiguation needed ] did not waste time. Putting the chariots in front, and following behind them himself with the cavalry, he ordered a charge. The chariots dashing into the Greek ranks, broke up their close formation, and the cavalry soon cut down about a hundred men. The rest fled and took refuge with Agesilaus, who happened to be close at hand with the hoplites.
The only other example of their successful use seems to be when units of Mithradates VI of Pontus defeated a Bithynian force on the River Amnias in 89BC. (Appian)
One of the most notable defeats to the Persian scythed chariot was in combat against the Macedonian phalanx led by Alexander the Great. Realizing that the chariots were already a cumbersome element of the Persian army (as shock units are prone to be) led by Darius III, the phalangites were instructed to increase this disadvantage. At the last seconds before the chariots would close with infantry, the phalangites would quickly fold into an enveloping formation in the shape of an E, where the middle tab would be the chariot. By doing this, the chariots would be trapped by the bodies of soldiers it killed, and the long Greek sarissa. This particular tactic was most successful at the Battle of Gaugamela, where Darius fled.
The statue of Boudica or Boudicea near Westminster Pier has her in a scythed chariot as commissioned by Prince Albert and executed by Thomas Thornycroft (completed in 1905).
Despite these shortcomings, scythed chariots were used with some success by the Persians, the kingdoms of the Hellenistic Era. They are last known to have been used at the Battle of Zela in 47 BC. The Romans are reported to have defeated this weapon system, not necessarily at this battle, with caltrops. On other occasions the Romans fixed vertical posts in the ground behind which their infantry were safe (Frontinus Stratagems 2,3,17-18) There is a statement in the Scriptores Historiae Augustae Severus Alexander LV that he captured 1,800 scythed chariots. This is universally regarded as false.
Late in the Imperial period, the Romans might have experimented with an unusual variant of the idea that called for cataphract-style lancers to sit on a pair or a single horse drawing a “chariot” reduced to a bare axle with wheels, where the blades were only lowered into the fighting position at the last moment. This would have facilitated manoeuvring before battle. This at least is a reasonable interpretation of the rather enigmatic de Rebus Bellicis section 12-14. (Most probably the 2-horse version was a practical weapon which inspired the 1-horse version as an underpowered paper innovation by the armchair author of this text.)
