Who can talk about Alexander the Great's Crusade and Macedonian phalanx in a popular way?

In order to cater to the intention of Greek and Macedonian slave owners to "bring war to Asia and bring wealth back to Greece" and to build an empire from Greece to India, King Alexander III of Macedonia launched a war of aggression against countries such as East Persia from 334 BC to 324 BC. Ten years later, after the battles of Isus, Goga, Milla and Jeddah, Alexander conquered Persia, Egypt, Asia Minor and the two river basins, and finally established the Alexander Empire across Europe, Asia and Africa.

Macedonian phalanx is a tactic of early infantry fighting. Since the Battle of Issa in 333 BC and the Battle of Goga Milla in 332 BC, the reputation of Macedonian phalanx has spread all over the ancient Mediterranean region.

The phalanges of each joint are composed of four primary phalanges. The primary phalanx is equivalent to a modern division, consisting of platoon-company-battalion-regiment-division. It is a self-contained multi-arms combat force, including heavy infantry (with Macedonian spears and round shields), light shield soldiers (with short spears and big round shields), auxiliary soldiers (with javelin, bow and arrow and slings as the main weapons) and cavalry (riding horses, holding spears and knives).

When fighting, it is arranged in a long horizontal line, and the depth is 16 people. There is a big gap between soldiers. Macedonian spears are usually held 3 to 6 feet from the handle end. On the head of the phalanx, the spearheads of the 4 to 6 rows of soldiers are aimed at the front, and the soldiers in the back row hold spears in different postures.

The whole phalanx often runs forward in a solid and dense formation, just like a siege hammer violently impacting the enemy's team. In order to protect the flank and rear, before the battle began, light lancers were arranged in a horizontal line with a depth of about 8 people behind the phalanx, and auxiliary soldiers (mostly heavy infantry orderlies and grain collectors) were arranged in a scattered line in front of the phalanx. The two wings are equipped with cavalry and a certain number of light cavalry. At the same time, the phalanx and the cavalry work closely together, requiring coordination of walking and riding.
