What was the nature of these campaigns?

Judges 1:9 (ESV)

9 And afterward the men of Judah went down to fight against the Canaanites who lived in the hill country, in the Negeb, and in the lowland.

These tribes were not taking over terrain that was completely new to them. This region had already been conquered by Joshua (Joshua 10:40). And the various tribes did go to live in their respective inheritances while Joshua was still alive (as is presupposed in Joshua 22:1–24:33). The present campaign, therefore, had as its single purpose the purging of their allotted territories of the Canaanites who had survived the earlier warfare or had returned later.1
