Summer heat bakes the eastern Syrian plains. Mercenaries from Egypt trudge northward alongside the Euphrates River. They grip heavy iron spears and bronze shields. The air smells of sweat and livestock. Men wait for orders near the shallow water crossings.
The defining military clash occurs in 605 b.c. King Nebuchadnezzar II leads the Babylonian infantry against Pharaoh Necho II. The Babylonian chronicle records this exact encounter. Egyptian forces attempt to secure the northern trade routes. Nebuchadnezzar drives his vanguard straight into the Egyptian defensive lines. The violent collision shatters Egypt entirely.
The river acts as a brutal natural trap. Babylonians push the retreating soldiers into the fast currents. Water levels run four feet deep across the fording points. Wounded men struggle against the flow while heavy armor pulls them under. Bodies wash downstream toward the southern deserts.
Swift water drowns the strongest swimmers who wear too much armor.
Survivors flee backward down the coast. They abandon their weapons in the dirt. Babylon seizes total control of the regional highways. The political map fractures permanently. Egyptian kings never march north of their borders again.
