Siege of Babylon
The siege of Babylon in 689 BC took place after the victory of Assyrian King Sennacherib over the Elamites at the Battle of River Diyala. Although the Assyrians had suffered heavy casualties at the river, they had beaten the Elamites and so the Babylonians now stood alone. Sennacherib then successfully besieged Babylon for up to fifteen months and destroyed it.
