The Battle of Thebes was a battle that took place between Alexander the Great and the Greek city-state of Thebes in 335 BC immediately outside of and in the city proper in Boeotia. After being made hegemon of the League of Corinth, Alexander had marched to the north to deal with revolts in Illyria and Thrace, which forced him to draw heavily from the troops in Macedonia that were maintaining pressure on the Greek city-states of the south to keep them in subjection. Although Alexander did not desire to destroy Thebes, after sending several embassies requesting their submission on what he considered merciful terms, he eventually decided to destroy the city as an example to others.
Background
Thebes had been under Macedonian occupation since the Battle of Chaeronea, which had resulted in the defeat and deposition of Thebes as the pre-eminent city-state of Southern Greece. The Thebans had reluctantly accepted this, as well as their compulsory membership in the League of Corinth, which had been previously imposed by Philip II of Macedon, Alexander's father. The expedition against Persia had been long in the works, and Alexander did not make it a secret that he planned to avenge the attacks on Greece by Persia a century and a half before, despite the fact that at the time his kingdom had been a Persianvassal state. It was as a result of this planned expedition that King Darius III started to distribute money to the Greek city-states with the hope that they would rise against their new hegemon. In addition to this, he had sent his most able general Memnon of Rhodes against the Macedonian troops that were already stationed in Ionia at this time. News of Alexander had not reached the southern Greek city-states for some time. He had been busy with the siege of Pelium and a rumour had reached them that he had died during the course of this siege. Demosthenes - a prominent Athenian politician - produced a man who claimed to have been present at the siege and claimed that Alexander was dead. Alexander had, indeed, been injured during this siege, so it was not a totally implausible claim to make. Upon learning of the alleged death of Alexander, Theban exiles in Athens raced off to their native city in Boeotia and sought to incite a revolt from Macedonian rule there. The Thebans received Persian monetary aid as did Demosthenes who used it to purchase weapons and other equipment and donated it to the Thebans. The Athenian Ecclesia signed a defensive alliance with the Thebans clearly aimed against the Macedonians. The Cadmaea, the citadel that was situated upon a hill in Thebes, was occupied by a Macedonian garrison, and it was this place that the Thebans sought to attack. To this effect, they killed two Macedonian officers who had been roaming the city, and declared their independence from Macedonia.
Alexander's march
When Alexander learned of the revolt of Thebes, he was immediately concerned about the situation. He had only secured the allegiance of the city-states at the beginning of his reign because he had an army present with which to bring the city-states to terms. This time, there was no such army present in southern Greece. As a result, many cities were throwing off the Macedonian yoke. He therefore raced south, hitting Thessaly by the seventh day and Boeotia by end of the next week. Having marched over three hundred miles in two weeks, the Thebans were shocked to see him in such close proximity to them, and did not believe that it was, in fact, Alexander at all, contesting that it was Antipater. He had passed through the pass of Thermopylae without any of the city-states knowing.
Alexander's arrival and siege
As Alexander arrived in Boeotia, many cities immediately deserted the cause of Greek independence and left Thebes to stand alone. Athens, led by Demosthenes, an inveterate opponent of Phillip, again denounced Macedonian hegemony and voted to support Thebes, supplying weapons, but Athens held back its forces, deciding to await events. The Spartans sent troops as far as the Isthmus of Corinth, but they also shrank from confronting Alexander. Though abandoned, the Theban assembly met and enthusiastically decided on war, defying Alexander's throng of experienced troops at their gates. Hesitant to destroy the city, he approached slowly and initially encamped far from the walls, hoping to dissuade the resisters. He offered relatively lenient terms: the surrender of Phoenix and Prothytes, leaders of the insurrection, with all others spared. The Thebans flung back at him the demand that he surrender Antipater and Philotas to them. The Cadmae citadel in Thebes, housing Alexander's garrison commanded by Philotas, had fortified itself against the Thebans in the outer city. The Thebans, in turn, had put a series of works surrounding the citadel, in addition to pallisades around the city. After three days preparation, Alexander divided his force in three parts. The first attacked the palisades and the second formed a line against the Theban infantry, with the third in reserve to reinforce gaps and press opportune advantages. For their defense, the Thebans emancipated their slaves and faced them towards the Macedonian attack on the wall. The Theban cavalry was placed within the palisades. The Thebans made everything ready to fight to the last man, and put their women and children in the city temples. In the assault, the Thebans fought desperately, fearing for their homes, wives, and children. The battle went on doubtfully for some time, but Alexander's reserves turned the tide. Alexander noticed that the Theban guard had abandoned one of their gates, and he seized the opportunity, sending Perdiccas' troops to take it and penetrate into the city itself. At this point, realizing that the walls were lost, the Thebans retreated into the city, but Philotas's garrison broke out of the citadel, surrounding the Thebans and ending the contest.
Destruction of Thebes
Alexander punished the Thebans severely for their rebellion. As an example to the other Greek states, he ordered the execution of all male inhabitants and the enslavement of the women and children. The city was burnt to the ground, sparing only of the house of Pindar, out of gratitude for Pindar's verses praising Alexander's ancestor, Alexander I of Macedon.
