 Turning to the 25th Division, Westmoreland suggested that it make a rapid thrust north with its 2nd Brigade a long Route 4 toward the Cambodian border in an attempt to spark an enemy reaction.As an objective, Westmoreland had in mind COSVN headquarters, reported to be situated near Katum.If COSVN remained elusive, the 2nd Brigade could turn west and drive toward Lo Go, a border village 35km northwest of Tây Ninh City that seemed to be a major supply base for War Zone C. In so doing the brigade would pass through a region where electronic intelligence reports had located various sections of COSVN headquarters.
