AornosW
Aornos

Aornos was the Ancient Greek name for the site of Alexander the Great's last siege, which took place on April 326 BC, at a mountain site located in modern Pakistan. Aornos offered the last threat to Alexander's supply line, which stretched, dangerously vulnerable, over the Hindu Kush back to Balkh, though Arrian credits Alexander's desire to outdo his kinsman Heracles, who allegedly had proved unable to take a fort that the Macedonians called Ἄορνος Aornos : meaning "birdless" in Greek. According to one theory, the name is a corruption of an Indo-Iranian word, such as *awarana "fortified place". According to Arrian, the rock had a flat summit well-supplied with natural springs and wide enough to grow crops: it could not be starved into submission. Neighboring tribesmen who surrendered to Alexander offered to lead him to the best point of access.

Alexander's Balkan campaignW

Cophen campaignW
Cophen campaign

The Cophen campaign was conducted by Alexander the Great in the Kabul Valley between May 327 BC and March 326 BC. It was conducted against the Aspasioi, the Guraeans, and the Assakenoi tribes in the Kunar valley of Afghanistan, and Panjkora (Dir) and Swat valleys in what is now Khyber Pakhtunkhwa, Pakistan. Alexander's goal was to secure his line of communications so that he could conduct a campaign in India proper. To achieve this, he needed to capture a number of fortresses controlled by the local tribes.

Siege of CyropolisW
Siege of Cyropolis

Cyropolis was the largest of seven towns in the region that Alexander the Great targeted for conquest in 329 BC. His goal was the conquest of Sogdiana. Alexander first sent Craterus to Cyropolis, the largest of the Sogdianan towns holding out against Alexander's forces. Craterus' instructions were to "take up a position close to the town, surround it with a ditch and stockade, and then assemble such siege engines as might suit his purpose....". The idea was to keep the inhabitants focused on their own defences and to prevent them from sending assistance out to the other towns.

The Battle of the Granicus River in May 334 BC was the first of three major battles fought between Alexander the Great and the Persian Empire.

Siege of HalicarnassusW
Siege of Halicarnassus

The siege of Halicarnassus was fought between Alexander the Great and the Achaemenid Persian Empire in 334 BC. Alexander, who had no navy, was constantly being threatened by the Persian navy. It continuously attempted to provoke an engagement with Alexander, who would not oblige them. Eventually, the Persian fleet sailed to Halicarnassus, in order to establish a new defense. Ada of Caria, the former queen of Halicarnassus, had been driven from her throne by her younger brother Pixodarus of Caria. When Pixodarus died, Persian King Darius had appointed Orontobates satrap of Caria, which included Halicarnassus in its jurisdiction. On the arrival of Alexander in 334 BC, Ada, who was in possession of the fortress of Alinda, surrendered the fortress to him.

Battle of the HydaspesW

The Battle of the Hydaspes was fought between Alexander the Great and King Porus in 326 BCE. It took place on the banks of the Jhelum River in the Punjab region of the Indian subcontinent. The battle resulted in a Greek victory and the surrender of Porus. Large areas of Punjab were absorbed into the Alexandrian Empire, and the defeated, dethroned Porus became reinstated by Alexander as a subordinate ruler.

Indian campaign of Alexander the GreatW
Indian campaign of Alexander the Great

The Indian campaign of Alexander the Great began in 327 BC.

The Battle of Jaxartes was a battle fought in 329 BC by Alexander the Great and his Hellenic (Greek) army against the Saka at the River Jaxartes, now known as the Syr Darya River. The site of the battle straddles the modern borders of Uzbekistan, Tajikistan, Kyrgyzstan and Kazakhstan, just south-west of the ancient city of Tashkent and north-east of Khujand.

Mallian campaignW
Mallian campaign

The Mallian campaign was conducted by Alexander the Great from November 326 to February 325 BC, against the Malli of the Punjab. Alexander was defining the eastern limit of his power by marching down-river along the Hydaspes to the Acesines, but the Malli and the Oxydraci combined to refuse passage through their territory. Alexander sought to prevent their forces meeting, and made a swift campaign against them which successfully pacified the region between the two rivers. Alexander was seriously injured during the course of the campaign, almost losing his life.

Siege of MiletusW
Siege of Miletus

The siege of Miletus was Alexander the Great's first siege and naval encounter with the Achaemenid Empire. This siege was directed against Miletus, a city in southern Ionia, which is now located in the Aydın province of modern-day Turkey. During the battle, Parmenion's son Philotas would be key in preventing the Persian Navy from finding safe anchorage. It was captured by Parmenion's son, Nicanor in 334 BC.

Siege of PeliumW
Siege of Pelium

The siege of Pelium was undertaken by Alexander the Great against the Illyrian tribes of what is modern-day Albania. It was critical for Alexander to take this pass as it provided easy access to Illyria and Macedonia, which was urgently needed in order to quell the unrest in Greece at this time in Athens and Thebes. This was an important point of demarcation in Alexander's early reign, as it established him among the Danubian tribes to the north as a serious monarch to be reckoned with, just as he would later establish this precedent for the Greek city states under his hegemony. Taking this place allowed Alexander to march his army to southern Greece quickly, which would eventually result in the total destruction of Thebes.

Battle of the Persian GateW
Battle of the Persian Gate

The Battle of the Persian Gate was a military conflict between a Persian force, commanded by the satrap of Persis, Ariobarzanes, and the invading Hellenic League, commanded by Alexander the Great. In the winter of 330 BC, Ariobarzanes led a last stand of the outnumbered Persian forces at the Persian Gates near Persepolis, holding back the Macedonian army for a month. Alexander eventually found a path to the rear of the Persians from the captured prisoners of war or a local shepherd, defeating the Persians and capturing Persepolis.

Sogdian RockW
Sogdian Rock

The Sogdian Rock or Rock of Ariamazes, a fortress located north of Bactria in Sogdiana, ruled by Arimazes, was captured by the forces of Alexander the Great in the early spring of 327 BC as part of his conquest of the Achaemenid Empire.

Siege of Tyre (332 BC)W
Siege of Tyre (332 BC)

The siege of Tyre was orchestrated by Alexander the Great in 332 BC during his campaigns against the Persians. The Macedonian army was unable to capture the city, which was a strategic coastal base on the Mediterranean Sea, through conventional means because it was on an island and had walls right up to the sea. Alexander responded to this problem by first blockading and besieging Tyre for seven months, and then by building a causeway that allowed him to breach the fortifications.

Battle of the Uxian DefileW
Battle of the Uxian Defile

The Battle of Uxian Defile was fought by Alexander the Great against the Uxian tribe of the Persian Empire. The battle raged on the mountain range between the key Persian cities of Susa and Persepolis. Persepolis was the ancient capital of the Persian Empire and held a symbolic value among the native Persian population. They believed that if this city were to fall into enemy hands, then, in effect, the whole Persian Empire would fall into the hands of the enemy.
