At the end of 317 B.C., Eumenes and his henchmen, mercenaries, and silver shields, a total of about 20,000 soldiers, set out from Phoenicia eastward, passing through Damascus and entering Mesopotamia. The governor www.biquge.info of Mesopotamia was Amphimachus, a cousin of Philip III, who joined Eumenes' camp and allowed him to recuperate here while preparing for the East.

The East, which was relatively stable at the time of the First Diadochi War, is now complicated and chaotic. It was Pesson, the Median governor who put down the Greek rebellion in Central Asia for Paddicka, and later participated in the assassination of Padica.

If there was anyone who was the most depressed after the First War of the Diadochi, many would think it was Eumenes. However, the depression in the heart of Pesson, the governor of the Medes, was no less than that of Eumenes. At the very least, Eumenes was on the wrong side and threw himself on Padica's side, and it was understandable that Paddicka was liquidated after his death. And Pesson of the Medes, since Alexander's death, has stood in the right position every time politically, and every battle he personally commanded has been victorious, but after three years of tossing and turning, he has not accumulated as much strength as when Alexander just died, this result is really full of irony for him.

At the time of Alexander's death, the entire Median region was his satrapy. In the Babylonian partition agreement, the governors agreed that the land was too large for Pesson to have alone, so they gave part of the northern part of the Median governorate to Atrobatus, the former Median governor of the Persian Empire and one of Padica's fathers-in-law. Although he suffered the setback of this reduction of the territory without any fault, Pei Song did not show much dissatisfaction, and perhaps he did not dare to express it. As a result, he temporarily won the trust of Padika and was appointed commander-in-chief to quell the Greek rebellion in Central Asia. Originally, he wanted to use this opportunity to expand his strength, but in fact, Padica had already guarded against him, and the result of the rebellion was that Peisong's soldiers slaughtered the Greek mercenaries who defected to him and divided the property, and he could be said to have gained nothing.

What followed was even more ironic: he had gone to great lengths to rendezvous with Padika from Central Asia to Syria, and as a result, Padika's invasion of Egypt was thwarted by the Nile. Feared by Padica's berserk state, High Rank Officers such as Person, Antignes, and Seleucus assassinated Paddicca. Ptolemy resigned as regent and elected Person and Aridaus as co-regents. For Pesson, his power was finally expanded, but what happened next was once again shocking, the puppet Philip III's wife Eurydic II suddenly attacked on the way back to the army, Peisson and Aridaus were unable to cope, and finally relied on the help of Antipater to reluctantly resolve the crisis. For Peisong, the former regent, the pinnacle of power in the Macedonian kingdom, passed by.

Pei Song was very dissatisfied and unwilling, so that after returning to the jurisdiction, he began to recruit troops almost immediately, and soon had a strong army of more than 20,000 people. He claimed that he had been entrusted by the Macedonian crown with jurisdiction over all the governorates of the Iranian plateau and east of the Iranian plateau when he put down the rebellion of the Greeks in Central Asia, and that this mandate should remain in force and that all the Macedonian governors of the Iranian plateau and east of it should obey him. However, Pei Song is not just a matter of asserting his own jurisdiction, he has never been a fuel-efficient lamp, he is the one who even the regent dares to kill. After he heard that Antipater had died of illness and that his former co-regent and friend Aridaus had begun attacking the Greek cities under his jurisdiction, Pesson set about his own campaign. The first unlucky was Philip, the governor of Parthia, who was defeated by surprise by Pesson, and then made his younger brother Eudemus the new governor of Parthia. …,

The news of the annexation of Parthia by Pesson, the governor of the Medes, spread throughout the East, causing panic among all the governors of the East, as the areas that Pezon claimed to have jurisdiction over included their jurisdictions. Therefore, they decided to unite against this arrogant and dangerous enemy. The members of the anti-Peisson coalition included almost every governor from the Iranian plateau to India. These eastern governors needed a leader, and at that time, Polybecon had not yet been defeated at the Battle of Hellespont and the attack of Eurydic, and their future superior, Eumenes, had not yet been inaugurated as the "Great General of Asia", and was still recruiting troops in Cilicia and Phoenicia to expand their fleets against Antigonus, so they could not have Eumenes, who was far away on the eastern shore of the Mediterranean, to command the anti-Pessonian coalition thousands of kilometers away. At this time, there was no doubt that there was only one man left in the East who could lead this combined army - Peusestas, the governor of Persia.

Peusestas was the eighth close guard officer of Alexander the Great, and was the same as the seven guards of Alexander before his death (the close guard officer Hephaestion died before the Great), and his status and influence were no less than that of Pesson. Among Alexander's major generals, he was the only one who was proficient in the Persian language and wore Persian clothing, thus making him a real blend of the Persians, so he had a high prestige among both Macedonians and Persians. As the governor of the former hinterland of the Persian Empire, including the capital Persepolis, he had at his disposal 3,000 Macedonian infantry, 10,000 locally recruited Persian light infantry (mainly archers and slingers), and 400 cavalry of Persian nobles. After Peisson's annexation of Parthia, Peusestas is likely to be Peussson's next target. The other governors of the anti-Pesson coalition had personally brought reinforcements, not as large as Peusestas himself, but they had brought the elite of their districts and provided a large number of cavalry. With these reinforcements, Peusestas' strength now reached about 20,000 infantry, 5,000 cavalry, and about 120 war elephants.

The main satraps who participated in the anti-Pezon coalition were: Alexander the Great's father-in-law, Oxyartes, the father of Roxanne, who was now the governor of Palopamisada (an area near present-day Pakistan); Strasanor, the governor of the combined Bactria and Sogdiana, was a leader in the Bactrian region during Alexander's time; Sibyrtius, governor of Alachosia and Gedrosia (Alachosia was relatively prosperous, while Getrosia was the "fish-eater region" of the Arabian Sea to the north and the deserts and mountains to the north, as described in Alexander's Expedition, and was extremely barren by the Indian governor Pesson; The Macedonian officer Eudemus (also known as Eudamus), who had recently murdered Porus (who took advantage of Porus' unsuspecting time to kill him by sneak attack and annex his army), brought with him a considerable force of 3,000 infantry, 500 cavalry, and 120 war elephants in Porus' possession.

After the departure of Pesong and Odmus in India, the greatest beneficiary was Chandragupta, the young king of the newly founded Mauryan Empire. He had been waiting for an opportunity to march north, and as Oldmus and Person had left with their best troops, the opportunity had finally arrived. Taking advantage of the westward march of the main forces of the Macedonian army to participate in the Diadochi War, he led his troops north, and with almost no effort, he occupied the two Macedonian governorates, and his territory reached the Hindu Kush. This is a natural border, so Chandragupta did not continue to use troops in the northwest direction, but of course, this is another story.

The anti-Pesson coalition was now in great force, marching on Parthia under the command of Peusestas, and Pezon led his army to meet it. After the fierce battle, Pei Song, who was numerically inferior, especially in terms of cavalry and war elephants, suffered a crushing defeat and lost a considerable number of troops. In desperation, he abandoned the Parthian province and returned to his Median province to continue to gather strength. …,

After recovering Parthia, the anti-Personic coalition did not pursue further into the Medes. They returned to the viceroyalty of Peusestas, and soon after, assembled in Susa to the west, where the viceroy Antijanis had by this time taken his troops to distant Cilicia on the orders of the regent Padica, to meet the common superior of the anti-Pessonian coalition and Pesson, Eumenes. This build-up of the anti-Pesson coalition was in preparation for the subsequent invasion of the Medes to punish Pesson.

Soon after, Pesson also traveled to the western neighbor province of Babylon to meet his old friend Seleucus in the city of Babylon. Although Pesson's claimed jurisdiction was large, his ambitions did not include Babylon of Seleucus, who had been his old partner in the murder of the regent Padica, and had a good relationship. He tried to convince Seleucus to join him in the fight against the satraps in the east.

While Pesson was trying to persuade Seleucus to join his side, Eumenes' envoys arrived in Babylon. What role did this play for Seleucus?

Concentrate:

Odysmos: The Greek name of Peson's younger brother is the same as that of the Indian governor Odysmos, so in order to avoid confusion, the Chinese translation was changed.

Peusestas: that is, Parksestas, many materials use Parks, but in order to better find it on Baidu, this Chinese translation name is used.
