Carchemish

Carchemish was a city by the river Euphrates, and Scripture mentions it as a place where great powers collided. When Josiah had finished repairing the temple, “Necho king of Egypt came up to fight against Carchemish,” and Josiah rode out to meet him. Years later Jeremiah names the same city while speaking about Egypt’s army, which Nebuchadrezzar of Babylon “smote” there. Isaiah also asks, “Is not Calno as Carchemish?” as part of a list of cities that fell. The place stands for armies on the move. Jeremiah 46:2 shows what happened there.

From Easton's Bible Dictionary

Matthew George Easton, 1897

Fortress of Chemosh, a city on the west bank of the Euphrates (Jer. 46:2; 2 Chr. 35:20), not, as was once supposed, the Circesium at the confluence of the Chebar and the Euphrates, but a city considerably higher up the river, and commanding the ordinary passage of the Euphrates; probably identical with Hierapolis. It was the capital of the kingdom of the northern Hittites. The Babylonian army, under Nebuchadnezzar, the son of Nabopolassar, here met and conquered the army of Pharaoh-necho, king of Egypt (B.C. 607). It is mentioned in monuments in B.C. 1600 and down to B.C. 717.

From Smith's Bible Dictionary

William Smith, 1884

(fortress of Chemosh) occupied nearly the site of the later Mabug or Hierapolis. It seems to have commanded the ordinary passage of the Euphrates at Bir or Birekjik . Carchemish appears to have been taken by Pharoah Necho shortly after the battle of Megiddo (cir. B.C. 608), and retaken by Nebuchadnezzar after a battle three years later, B.C. 605. (Jeremiah 46:2)
