The Isenmouthe lay between where the Ephel Dúath and the Ash Mountains mountain ranges met and was a narrow passage. The pass was heavily guarded with Fortresses and watchtowers overlooking it. There was also a wall of earth built across the passage and a large ditch dug across the entrance spanned only by a single bridge.
