The Bolo deception was executed successfully. The North Vietnamese believed they faced an F-105 flight and dispatched their MiGs. The later-arriving F4s prevented the MiGs from returning to their base. The 8th Fighter Wing destroyed seven MiGs in a matter of minutes, while Olds' fighters sustained no losses. The destruction of half their MiGs and uncertainty about whether future flights observed on radar and electronic sensors were unescorted F-105s or F-4s pretending to be F-105s caused North Vietnam to ground its MiGs. The MiGs failed in their mission of preventing U.S. Operation Rolling Thunder bombing runs over North Vietnam.
