 If the move to Lo Go came up empty, Weyand was to end Attleboro and wait for new intelligence before reinitiating operations in War Zone C.

While the two commanders discussed the last phase of Attleboro, the 2nd Brigade of the 25th was searching for the 271st Regiment east of Route 4 and north of the French fort.When the change of orders from II Field Force arrived on the 14th, O'Connor instructed the brigade's commander, Colonel Thomas M. Tarpley, to terminate that operation and move north to find COSVN.The following day, 15 November, Tarpley's brigade began its advance, spearheaded by two mechanized battalions.
