The total defeat of the tribe of Benjamin ends with a desperate escape by a handful of survivors. Realizing the battle is completely lost, the remaining fighters turn away from the conflict to run for their lives [ביאור שטיינזלץ]. Exactly six hundred men manage to get away. These men are the absolute last remnants of their tribe, as the Israelites killed all the others during the pursuit [מצודת דוד].
Because this surviving group flees directly from the active battlefield, it consists entirely of soldiers. This creates a deeply tragic situation, as not a single woman from the entire tribe of Benjamin remains alive [רד״ק].
Seeking a safe haven, the survivors escape into the wilderness and hide among the rocky cliffs [ביאור שטיינזלץ]. This location serves as a naturally strong and protected fortress, offering them secure shelter [אברבנאל]. They remain hidden in this refuge for four months. This extended stay is possible because the Israelites eventually lose interest and choose not to hunt them down any further [ביאור שטיינזלץ].
