What happened
West Asia (11)
Alexander asked to make a sacrifice to Heracles and entered Tyre, but Tyre resolved to admit neither Macedonians nor Persians. Enraged, Alexander sent the envoys away. (Arrian, Anabasis of Alexander 2.16.1–2.16.8)
He persuaded his officers with a speech, and in a dream Heracles took him by the hand and led him on. He began building a causeway from the mainland toward the island city. As the water deepened, the Tyrians' triremes and wall-fire harassed the work, so he erected two towers. (Arrian, Anabasis of Alexander 2.18.1–2.18.3)
The Tyrians filled a horse-transport ship with dry wood and pitch and rammed it into the causeway, burning the towers and machines. Alexander ordered a wider causeway built and sailed to Sidon to assemble the fleet. (Arrian, Anabasis of Alexander 2.19.1–2.19.6)
At midday the Tyrians ambushed the Cypriot fleet and sank three ships. But Alexander returned quickly, counterattacked at the harbor mouth, drove the Tyrian fleet into a corner, and tested the walls. A section of wall collapsed. (Arrian, Anabasis of Alexander 2.22.1–2.22.2)
Using ships that had been lashed together as bridges, Alexander climbed onto the walls and took the city. About 8,000 Tyrian fighters died, 400 Macedonians fell, and about 30,000 were sold into slavery. Those who fled to the temple of Heracles were pardoned. Hekatombaion, archon Anikētos. (Arrian, Anabasis of Alexander 2.24.1–2.24.2)
Envoys from Darius offered 10,000 talents, the land west of the Euphrates, and a marriage with his daughter, but Alexander refused. Batis, the eunuch of Gaza, refused to let him in. (Arrian, Anabasis of Alexander 2.25.1–2.25.4)
The engineers said it was impossible because of the high mound by Gaza's walls, but Alejandro raised a mound and set up the machines. During a sacrifice a bird dropped a stone on his head; Aristander interpreted that he would take the city but must take care of his body. (Arrian, Anabasis of Alexander 2.26.1–2.26.4)
Alexander was wounded in the shoulder by a catapult bolt. Using machines brought from Tyre, they built mounds on all sides and broke through the wall on the fourth assault to take the city. All Gazans fought and died, and their wives and children were enslaved. He settled the city with neighboring residents and used it as a fortress. (Arrian, Anabasis of Alexander 2.27.1–2.27.7)
On the seventh day from Gaza he reached Pelusium, where the fleet met him. The governor Mazakes welcomed him in a friendly way; he left a garrison there and marched toward Memphis. (Arrian, Anabasis of Alexander 3.1.1–3.1.5)
Passing through Heliopolis and crossing the Nile, at Memphis he made sacrifices to Apis and the gods, and held games of Greek artists. (Arrian, Anabasis of Alexander 3.1.1–3.1.3)
When Alexander of Epirus lands near Paestum, the Samnites and Lucanians unite but are beaten in a pitched battle (Livy, History of Rome (Ab Urbe Condita) 8.17)
