If it is pedantic, then why do ALL of the accounts you mentioned go out of their way to make the point that it is God's action, not the people's action that wins the day?

"The Lord will fight for you, you need only be still."

"For the Lord has given you the city!"

"You have too many men... ...In order that Israel may not boast... ...that her own strength has saved her..."

This entire post has been misguided. First confusing trumpets with horns. Then the top response mis-attributing the source of victory.

We are in for a long fight. Sometimes we will be feeling up and powerful but sometimes we will also be feeling down and vulnerable. It is critical for us to understand "Do not put your trust in princes, in mortal men who cannot save."

"Some trust in chariots and some in horses, but we trust in the name of the Lord our God."

Our job is to be obedient and to have faith that God will win the day. This might mean that we do some unusual things a la Moses, Joshua, or Gideon, but these actions are done in obedience and not in our own strength (see Numbers 14.40-45).
