What does Judges 20:24 mean?

Day two dawns in a battle between eleven of Israel's twelve tribes and the remaining tribe of Benjamin (Judges 20:12–17). The first day had been a complete disaster, with about one in twenty of Israel's soldiers being killed in the initial attack (Judges 20:18–21). The people wept and returned to Bethel to ask the Lord if He really wanted them to attack the tribe of Benjamin, their own Israelite brothers. God has responded that they should continue their efforts (Judges 20:22–23).

With their battle lines already formed, the Israelites now initiate their second attack. Once more, Benjamin's defenses surrounding the city of Gibeah will be too much to overcome (Judges 20:25).
