The FANK launched an unsuccessful counter-attack on 27 October, and the Cambodian corridor along Route 6 was crushed by PAVN/VC troops after weeks of heavy fighting. Elements of the PAVN 9th Division then launched a final attack which ripped apart several FANK and Khmer Krom battalions, causing the disorganized Cambodian troops to abandon several key positions on 1 December. The operation was terminated two days later.
