Due to bad weather, the helicopter deployment from Landing Zone Snapper was delayed and 2/3 Marines marched into the salient establishing Firebase Saigon (16°31′26″N106°42′11″E / 16.524°N 106.703°E / 16.524; 106.703)[2]: 454 overlooking Route 616.

In early April the PAVN began firing rockets and artillery on the salient from positions in Laos causing limited damage as the Marines had already begun to leave the area. On 6 April control of Task Force Remagen passed from the Marines back to the Army which began operations on the Khe Sanh plateau and later the 3rd Battalion, 2nd ARVN Regiment which had been based at Landing Zone Torch (16°31′26″N106°47′13″E / 16.524°N 106.787°E / 16.524; 106.787)[2]: 517 east of Landing Zone Saigon was lifted back to Đông Hà Combat Base.
