In my rush to finish up last night before bed time I forgot a couple important details in the conclusion.
In Chapter 8 Joshua goes against Ai again. You would think that since it was Achan's fault that the first attack failed on Ai Joshua wouldn't really need to change strategy. It wasn't the strategy that caused the defeat it was Achan stealing the loot, but that's not how Joshua sees things. He knows it was a strategic failure and that he violated God's commandments re leading all of Israel into battle. So this time Joshua does in fact lead all the newly reunited Israel into battle, he doesn't sit back and let just a small contingent do the dirty work.
The second interesting thing is that in 8:2 he immediately rescinds the ban, now it ain't so bad to have privatized loot.
The first attack ended with the human sacrifice of Achan, the second attack ended with subdued animal sacrifice.
