Editor's Prelude
The Campaign That Became a World
Prepared by the NEXUS Editors
Anabasis of Alexander is an ancient campaign history: a march narrative, a war record, and a test of what happens when one man’s ambition keeps outrunning the known map. Arrian wrote more than four centuries after Alexander’s death, but he was not writing from loose legend. He was a Greek-speaking Roman soldier and statesman, and he leaned especially on Ptolemy and Aristobulus, men who had known the expedition from inside its world.
That matters because Alexander is easy to flatten into a symbol: genius, conqueror, monster, youth, myth. Arrian gives him back to movement. Rivers have to be crossed. Cities have to be taken or spared. Armies mutiny, wounds deepen, advisers vanish, and victory keeps creating new borders that demand still more victory. The book’s power is in that pressure: the sense that every triumph widens the field and makes the next decision more dangerous.
Discipline runs beneath the grandeur. Arrian admires Alexander, but he also judges him; he wants the record to survive the intoxication of fame. What follows is not a clean hero tale. It is a long campaign through courage, calculation, endurance, cruelty, loyalty, exhaustion, and the strange loneliness of command when the world has begun to open and there is no obvious place to stop.
The opening pages
Book I, Chapters V-VII: Illyria and Thebes
CHAPTER V.
Revolt of Clitus and Glaucias.
He then advanced into the land of the Agrianians and Paeonians, where messengers reached him, who reported that Clitus, son of Bardylis, had revolted, and that Glaucias, king of the Taulantians, had gone over to him. They also reported that the Autariatians intended to attack him on his way. He accordingly resolved to commence his march without delay. But Langarus, king of the Agrianians, who, in the lifetime of Philip, had been an open and avowed friend of Alexander, and had gone on an embassy to him in his private capacity, at that time also came to him with the finest and best armed of the shield-bearing troops, which he kept as a body-guard. When this man heard that Alexander was inquiring who the Autariatians were, and what was the number of their men, he said that he need take no account of them, since they were the least warlike of the tribes of that district; and that he would himself make an inroad into their land, so that they might have too much occupation about their own affairs to attack others. Accordingly, at Alexander’s order, he made an attack upon them; and not only did he attack them, but he swept their land clean of captives and booty. Thus the Autariatians were indeed occupied with their own affairs. Langarus was rewarded by Alexander with the greatest honours, and received from him the gifts which were considered most valuable in the eyes of the king of the Macedonians. Alexander also promised to give him his sister Cyna in marriage when he arrived at Pella. But Langarus fell ill and died on his return home.
After this, Alexander marched along the river Erigon, and proceeded to the city of Pelium; for Clitus had seized this city, as it was the strongest in the country. When Alexander arrived at this place, and had encamped near the river Eordaicus, he resolved to make an assault upon the wall the next day. But Clitus held the mountains which encircled the city, and commanded it from their height; moreover, they were covered with dense thickets. His intention was to fall upon the Macedonians from all sides, if they assaulted the city. But Glaucias, king of the Taulantians, had not yet joined him. Alexander, however, led his forces towards the city; and the enemy, after sacrificing three boys, an equal number of girls, and three black rams, sallied forth for the purpose of receiving the Macedonians in a hand-to-hand conflict. But as soon as they came to close quarters, they left the positions which they had occupied, strong as they were, in such haste that even their sacrificial victims were captured still lying on the ground.

Preface and Book I, Chapters I-IV: Northern Frontiers
Arrian Sets His Standard
Arrian starts by explaining his witnesses, then shows Alexander securing power before Asia.
Reading checkpoint
Arrian prefers the eyewitness accounts of Ptolemy and Aristobulus and explains how he handles their disagreements. The narrative then turns to Alexander's first task: securing Macedonia's northern frontier before the Persian expedition.
Why it matters
Alexander's speed is already the point. Rivers, mountains, and distant tribes become tests of command before he ever meets the Persians.
The ending
The Celtic envoys say that they fear the sky falling, rather than Alexander. He makes them friends and allies, but calls them braggarts: their answer denies him the personal awe he had expected.
Book I, Chapters V-VII
Revolt Tests The Young King
Alexander has to prevent frontier rebellion and Greek revolt from joining into one crisis.
What just happened
The Illyrian rulers Clitus and Glaucias, followed by the revolt at Thebes, test whether Alexander's new power is stable. Arrian makes the danger cumulative: enemies are watching to see whether youth means weakness.
Why it matters
Before Asia, Alexander must prove that Macedonia cannot be pulled apart behind him. Thebes becomes the most serious Greek test of that authority.
The ending
The movement ends with Alexander still holding back from an assault on Thebes. He waits near the Cadmea in hope of a settlement, while the exiles most committed to revolt resist reconciliation.
