The Carthaginians under Hamilcar take advantage of their victory at Thermae in Sicily by counterattacking the Romans and seizing Enna. Hamilcar continues south to Camarina, in Syracusan territory, to try to convince the Syracusans to rejoin the Carthaginian side.
The Romans are able to regain the initiative in Sicily against Carthage by retaking Enna and Camarina. In central Sicily, they take the town of Mytistraton, which they have attacked twice previously. The Romans also move in the north by marching across the northern coast toward Panormus, but are not able to take the city due to the city's heavily fortified walls.
Gaius Duilius Nepos, the Roman commander who has won a major naval victory over the Carthaginians is made censor with Lucius Cornelius Scipio. The election of a novus homo (i.e. the first in his family to serve in the Roman Senate or be elected as consul) to the censorship is a very rare honor.
The forces of the Macedonian King Antigonus II and the Seleucid King Antiochus II win a naval victory at Cos against their common enemy, Ptolemy II. This victory secures Antigonus control over the Aegean Sea and the League of the Islanders. It also diminishes Ptolemaic naval power.
The State of Qin besieges Handan, the capital of the State of Zhou, but the Qin army under Wang Ling sustains heavy casualties. Wang Ling is then replaced by Wang He.[2]
The merchant Lu Buwei rescues the Qin prince Ying Yiren, a hostage at the Zhao court, from Handan. Ying Yiren will eventually become King Zhuangxiang of Qin.[3]
The Battle of Tyndaris is fought between the Roman fleet (with Gaius Atilius Regulus in command) and the Carthaginian fleet off Tyndaris (modern Tindari) in Sicily. Hiero II, tyrant of Syracuse, has allowed Tyndaris to be a base for the Carthaginians. However, after this battle, the town falls to Roman forces.
The State of Chu and the State of Wei send armies to assist Zhao against the Qin, and they defeat the Qin army of Wang He outside Handan. This forces Wang He to lift the siege.
The Qin general Bai Qi is executed for his refusal to take command of the siege.[4]
Rome aims for a quick end to hostilities in the First Punic War and decides to invade the Carthaginian colonies in Northern Africa to force the enemy to accept terms. A major fleet is built, including transports for the army and its equipment, and warships for their protection. Carthage under Hamilcar tries to intervene but a force under the Roman general and consulMarcus Atilius Regulus and his colleague Lucius Manlius Vulso Longus defeat the Carthaginian fleet in the Battle of Cape Ecnomus off the southern coast of Sicily.[5]
Following the Battle of Cape Ecnomus, the Romans land an army near Carthage (Tunesia, North Africa) and begin ravaging the Carthaginian countryside. The Roman army soon forces the capitulation of Clupea, a town 40 miles (64 kilometres) east of Carthage. After setting up Roman defenses for the city, the two consuls receive instructions from Rome that Vulso is to set sail for Rome, taking most of the fleet with him. Regulus, on the other hand, is to stay with the infantry and cavalry to finish the war.[6]
The Du Jiang Yan Irrigation System is constructed, ending flooding and irrigating thousands of square miles of land through an ingeniously designed system.[9]
The Battle of Adis (or Adys) is fought near the city of that name, 40 miles (64 kilometres) southeast of Carthage, between Carthaginian forces and a Roman army led by Marcus Atilius Regulus. The Romans inflict a crushing defeat upon the Carthaginians, and the latter then sue for peace. The ensuing negotiations between the parties lead to Regulus demanding Carthage agree to an unconditional surrender, cede Sicily, Corsica and Sardinia to Rome, renounce the use of their navy, pay an indemnity, and sign a vassal-like treaty. These terms are so harsh that the people of Carthage resolve to keep fighting.[10]
The Carthaginians, angered by Regulus' demands, hire Xanthippus, a Spartan mercenary, to reorganize the army. The revitalised Carthaginian army, led by Xanthippus, decisively defeat the Romans in the Battle of Tunis and capture their commander Marcus Atilius Regulus. A Roman fleet, sent to rescue Regulus and his troops, is wrecked in a storm off Sicily.[11]
The war is concluded with the marriage of Antiochus to Ptolemy II's daughter, Berenice Syra. Antiochus divorces his previous wife, Laodice, and transfers the succession to Berenice's children.[18]
In recapturing the city of Miletus, Antiochus II overthrows the tyrant of the city. In response, the citizens worship him as a god in thanksgiving leading to the addition of Theos to Antiochus II's name.[19]
Alexander, Antigonus II's nephew and regent, leads a revolt in Corinth with Ptolemy II's help and declares himself an independent monarch. As a result, Antigonus loses Corinth and Chalcis, the two bases from which he has dominated southern Greece. As the Aetolians occupy Thermopylae, Antigonus II is cut off from Athens and the Peloponnese.
Macedonia's involvement in the second Syrian War ceases when Antigonus becomes preoccupied with the rebellion of Corinth and Chalcis, as well as an increase in enemy activity along Macedon's northern frontier.
Paseas, the tyrant of the Greek city-stateofSicyon, is assassinated by Nicocles, with the acquiescence of the Macedonian king Antigonus II. Nicocles reigns as tyrant of Sicyon for only four months, during which period he drives into exile eighty of the city's citizens. Then the citadel of Sicyon is surprised in the night by a party of Sicyonian exiles, headed by a young nobleman, Aratus. The palace of the tyrant is set on fire, but Nicocles escapes from the city through a subterranean passage.
Aratus recalls back to Sicyon those exiled by Nicocles. This leads to confusion and division within the city. Fearing that Antigonus II will exploit these divisions to attack the city, Aratus applies for the city to join the Achaean League, a league of a few small Achaean towns in the Peloponnese. Aratus then gains the financial support of the Egyptian king Ptolemy II to enable the Achaean League to defend itself against Macedonia.
With Panormus captured, much of western inland Sicily falls with it. The cities of Ieta, Solous, Petra and Tyndaris agree to peace with the Romans in the same year. This defeat marks the end of significant Carthaginian land-based campaigning in Sicily.
The Zhao general Lian Po wins a decisive victory in battle over the State of Yan at Hao. He is promoted to Prime Minister following the death of Lord Pingyuan.[24]
Following the death of the King of Cyrene, Magas, Queen Apama II, Magas' widow, and Antigonus II arrange the marriage of Antigonus' half-brother Demetrius the FairtoBerenice of Cyrene, daughter of Magas and Apama. However, when Demetrius the Fair arrives, Apama becomes his lover. In response, Berenice leads an uprising in which Demetrius is killed in Apama's bedroom.
According to tradition (Horace, Odes, iii. 5), after the defeat of the Carthaginians at the Battle of Panormus, the Carthaginians release Marcus Atilius Regulus from prison and he is sent to Rome on parole to negotiate a peace or an exchange of prisoners. However, on his arrival, he strongly urges the Roman Senate to refuse both proposals and continue fighting. After this he then honours his parole by returning to Carthage where he is executed by being placed in a spiked barrel, which is then let roll down a hill.
