The Battle of Gaza of 312 BC, was fought between the invading army of Ptolemy I Soter and his ally Seleucus I Nicator and the defending army of Demetrius I of Macedon, son of Antigonus I Monophthalmus. The battle was part of the Third War of the Diadochi and was fought near the city of Gaza.

In late 312 BC, Ptolemy launched an invasion into the Levant from Egypt, he marched with 18,000 infantry and 4,000 cavalry along the northern edge of the Sinai Peninsula. Receiving timely intelligence, Demetrius recalled his troops from their winter quarters and concentrated them at Gaza. Demetrius' advisors had apparently told him to avoid a military confrontation with Ptolemy and Seleucus, who had more military experience, but he ignored their advice; the conflict ended in a decisive defeat for Demetrius, subsequently enabling the absorption of his controlled territory by Ptolemy and Seleucus.

Armies and deployment

Troop strength

Demetrius deployed 2,900 elite cavalry, 1,500 light infantry, and 30 Indian war elephants under his command on the left. The Antigonid phalanx of some 11,000 was deployed in the center, with 13 war elephants in front and light infantry protecting the main line. On the Antigonid right, there were 1,500 cavalry.

Ptolemy and Seleucus originally put most of their cavalry on the left, but when they learned of Demetrius' disposition, they massed their 3,000 heavy cavalry to the right, under their personal command. An anti-elephant corps of 3,000 light infantry (peltast, archers and slingers) equipped with anti-elephant devices (spikes connected by chains) were positioned in front of the cavalry,– with orders to throw the devices in the path of the elephants and then target the mahouts. Their phalanx was stationed in the center, with the remaining 1,000 cavalry deployed on the right.

Alfred Duggan's novel on the life of Demetrius, Elephants and Castles, covers the battle.

The third novel in Christian Cameron's Tyrant series, Funeral Games features the Battle of Gaza.
