Trumpets and torches trigger Midian's flight

Three companies surround the camp with trumpets, jars, and lamps

Gideon divides the three hundred into three companies and puts a trumpet in every man's hand, with empty pitchers and lamps within the pitchers. He says, Look on me, and do likewise. When he comes to the outside of the camp, they are to blow the trumpets and cry, The sword of the LORD, and of Gideon. They stand every man in his place round about the camp.

The cry names God and Gideon together. It is this night's shout, not proof that every force that attaches God's name belongs to God, and not a template for covert political violence.

The LORD sets sword against sword; pursuit kills Oreb and Zeeb

In the beginning of the middle watch they blow the trumpets and break the pitchers. The three companies hold the lamps in their left hands, the trumpets in their right, blow, and cry. The host runs, cries, and flees. The three hundred blow, and the LORD sets every man's sword against his fellow throughout the host. The army flees toward Beth-shittah, Zererath, Abel-meholah, and Tabbath.

Gideon sends messengers through mount Ephraim to take the waters unto Beth-barah and Jordan. Ephraim takes the waters, captures two princes of Midian, Oreb and Zeeb, kills them, and brings their heads to Gideon. Coordinated sound and light expose panic. The victory immediately widens into pursuit, executions, and the honor quarrel of the next unit. Captured princes' deaths are not permission for extrajudicial killing.
