Sodom's army, and those of her four smaller allies, lay destroyed in the Valley of Siddim. The settlements of the giants East (from North to South) of the Jordan valley were in ruins never to recover (Joshua encountered only the last of them, Og the King of Bashan, more than five hundred years later). The Amalekites southwest in the Negev would eventually recover to harass Israel, but for now they were decimated.
Salem had been spared.
Abraham, with an army of 318 trained men (no word on casualties) and local Amorite allies had just eliminated the (likely) much larger raiding force from the lands around later Babylon and Persia, which had taken at least a year to raise. No word on how many had fled (if any), including the four kings themselves, but it had been an unqualified victory.
Abraham recovered everyone that he and Sodom and the other cities had lost. Abraham had the blessing of the remaining city of size in the area (Salem). Sodom, the ruined large city of the region was in his debt.
Abraham was now the dominant military power in the region, such that he spoke for his Amorite friends in dividing the spoils recovered from Sodom, and the king of Sodom was trying to entice Abraham away from a presumed tenancy covenant with the king of Salem.
Abraham is afraid.
