No survivors

Joshua 10:40-42 - So Joshua subdued the whole region, including the hill country, the Negev, the western foothills and the mountain slopes, together with all their kings. He left no survivors. He totally destroyed all who breathed, just as the LORD, the God of Israel, had commanded. Joshua subdued them from Kadesh Barnea to Gaza and from the whole region of Goshen to Gibeon. All these kings and their lands Joshua conquered in one campaign, because the LORD, the God of Israel, fought for Israel.

I wonder if Joshua's army ever got tired. They were always fighting fresh enemies. Maybe only certain divisions were deployed for a given battle (as was first tried at Ai).

I wonder how long this campaign took. How long did they rest between battles? How long did it take to get from one city or battlefield to the next?

In this campaign, Joshua and Israel accomplished the following:

• Defeated Jericho
• Defeated Ai (on the second attempt)
• Made peace with Gibeon
• Defeated the armies of Jerusalem, Hebron, Jarmuth, Lachish, and Eglon who had attacked Gibeon
• Defeated Makkedah
• Defeated Libnah
• Defeated what was left of Lachish, Eglon, and Hebron
• Defeated Debir

In virtually every battle, they left no survivors. I wonder if Joshua left a detachment of soldiers behind in each of these cities to police it and mark it as belonging to Israel.
