Suspicions and diversions

This course of events disturbed Lieutenant General Frederick Weyand, commander of U.S. forces in III Corps, which included the sensitive Capital Military District. Weyand, a former intelligence officer, was suspicious of the pattern of communist activities in his area of responsibility and notified Westmoreland of his concerns on 10 January. Westmoreland agreed with his estimate and ordered 15 U.S. battalions to redeploy from positions near the Cambodian border back to the outskirts of Saigon.: 8 When the offensive did begin, a total of 27 allied maneuver battalions defended the city and the surrounding area. This redeployment may have been one of the most critical tactical decisions of the war.
