As the time for battle arrives, Gideon moves from careful planning to decisive action. He equips his small, dedicated group of fighters with highly unusual gear, designed to unleash a devastating psychological strike against the enemy camp under the cover of darkness. The men are divided into three distinct groups, a strategic move intended to create the illusion of a massive, overwhelming army surrounding the enemy from all sides. This tactic directly echoes the strategy used by Abraham during his war against the four kings [מלבי״ם, אברבנאל].
The primary approach among commentators is that Gideon orchestrated a sophisticated, multi-stage military deception. Every fighter is given a horn, an empty pitcher, and a burning torch [מצודת ציון, ביאור שטיינזלץ]. The horns are meant to generate a deafening war cry that would shatter the enemy's morale and further amplify the illusion of a vast multitude. Meanwhile, the torches and pitchers serve a brilliant dual purpose of camouflage and surprise. Because the operation takes place on a pitch-black night, the torches are necessary to light the way. However, they are concealed inside the empty pitchers—which were likely gathered from the thousands of soldiers who had been sent home earlier—ensuring that the enemy would not detect their quiet approach [רש״י, אברבנאל, ביאור שטיינזלץ].
The climax of this ambush is meticulously timed. By suddenly shattering the pitchers all at once, the men would produce a terrifying, thunderous crash. Immediately following this noise, the abrupt exposure of the flaming torches in the dead of night would create a shocking spectacle of fire and smoke, instantly sowing absolute panic and confusion throughout the Midianite camp [מלבי״ם, אברבנאל].
Beyond the brilliant military logic, many commentators recognize a profound spiritual and symbolic layer in Gideon's chosen tactics. The specific equipment and methods are designed to awaken past merits and invoke God's mercy during this moment of extreme danger. A prominent view suggests that the terrifying combination of horn blasts, flaming torches, and the thunderous noise of shattering clay is meant to evoke the merit of the revelation at Mount Sinai, where the Israelites similarly experienced overwhelming sounds, torches, and the blast of a horn [רש״י, אלשיך, אברבנאל]. Another perspective connects the strategy to the merit of the three Patriarchs. The division of the men into three factions represents Abraham, Isaac, and Jacob; the horns recall the ram offered in place of Isaac; and the sudden, loud crash of the pitchers symbolizes the powerful voice of Jacob [אלשיך, חומת אנך].
Alternatively, the division of the force into three groups is seen as a subtle reminder of Gideon's own personal merits. He had previously risked his life to defend the holiness of God through three distinct acts: cutting down the idolatrous Asherah tree, destroying the idolatrous altar, and slaughtering the bull. Gideon intentionally chooses to channel these merits quietly through his tactical actions rather than declaring them aloud, ensuring he does not invite any spiritual scrutiny or accusation against himself in the heat of war [חומת אנך].
