Joshua 10:36 - Matthew Poole's English Annotations on the Holy Bible

Which though they took and killed all its inhabitants, yet they did not keep it; and therefore when Joshua and his army had forsaken it, and were returned to Gilgal, it seems the giants and other Canaanites being burnt out, or driven away from their former seats, planted and fortified themselves there; which made it necessary for Caleb to take it a second time, as is recorded Joshua 15:14 Judges 1:10. Or this is the same story, and the same conquest of Hebron, which is here generally related, and afterwards repeated, and more particularly described, Joshua 15:13,14.
