Following the conclusion of Operation Tulsa, BG William E. DePuy kept Col. Sidney Berry's 1st Brigade in the field hoping to repeat the success of the Battle of Minh Thanh Road by establishing firebases in the area and then sending convoys along Highway 13 and the Minh Thanh Road to invite attack by the Viet Cong (VC).
From 18 October 1st Brigade sent units from its base at Quần Lợi Base Camp along Highway 13 to Lộc Ninh, this did not provoke any response from the VC. From 24 October patrols were sent southwest onto the Minh Thanh Road but the VC also ignored these. From 25 to 26 October the Brigade searched the Minh Thanh Plantation without success.:334
On 28 October patrols encountered a VC force and Col. Berry ordered the 1st Battalion, 26th Infantry Regiment (1/26th Infantry) and the 1st Battalion, 28th Infantry Regiment (1/28th Infantry) to search the area. A platoon from the 1/26th Infantry ambushed a VC unit and Col. Berry decided to surround it by airlifting the 2/28th Infantry to the west of the scene while the 2nd Battalion, 18th Infantry Regiment was landed to the south, while the 1/26th Infantry covered the north and 1/28th Infantry covered the west. With this cordon established, at 17:45 the target area was hit by over 2000 rounds of artillery fire and 70 air sorties. During the night most of the VC were able to escape to the southwest through gaps in the American lines.:335–6
On 29 October BG DePuy assumed direct command of the operation and deployed his units to the southwest to search the probable escape routes, but they were unable to locate the VC. A search of the battlefield found 60 VC dead.:336
Operation Shenandoah officially concluded on 2 November. BG DePuy considered it a limited success as the VC 9th Division generally avoided battle. Total US casualties were 5 killed, while VC losses were claimed to be 74 killed.:336

The 9th Infantry Division is a division of the People's Army of Vietnam (PAVN), first formed from Viet Cong units in 1964/5 in the Mekong Delta region.Battle of Ong Thanh
The Battle of Ong Thanh was fought at the stream of that name (Ông Thành) on the morning of 17 October 1967, in Chơn Thành District, at the time part of Bình Dương Province, South Vietnam, today in Bình Phước Province.
During the first few months of 1967, the Viet Cong (VC) absorbed heavy losses as a result of large-scale search and destroy missions conducted by the United States Army, and it prompted North Vietnamese leaders to review their war strategy in South Vietnam. In light of the setbacks which People's Army of Vietnam (PAVN) and VC forces had experienced early in 1967, PAVN General Trần Văn Trà suggested that PAVN and VC forces could still be victorious if they inflicted as many casualties as possible on U.S. military units, hoping that the Americans would conclude that the war was too costly and withdraw from Vietnam. Thus, towards mid-1967, the VC 7th and 9th Divisions returned to the battlefield again, with the objective of inflicting casualties on U.S. military formations in III Corps. On June 12, the U.S. 1st Infantry Division launched Operation Billings to destroy elements of the VC 9th Division, which had built-up strength around northern Phước Vĩnh. When the operation concluded on June 26, the 1st Infantry Division had lost 57 killed while the VC had lost 347 killed. Then in September, following a string of attacks on allied military installations by VC and PAVN troops, Major General John H. Hay decided to temporarily stop conducting large-scale operations until the true intentions of PAVN/VC forces were known. Towards October, the VC 271st Regiment marched into the Long Nguyen Secret Zone, to rest and refit for their next major operation. To disrupt the VC's resting period, General Hay launched Operation Shenandoah II to clear a section of Highway 13 which stretched from Chơn Thành to Lộc Ninh.
Starting from 28 September, elements of the 1st Infantry Division were air-lifted into positions around Long Nguyen, but again only few contacts were made with the VC. However, on 16 October, the 2nd Battalion, 28th Infantry Regiment found a major VC bunker system located south of their night defensive position near the Ong Thanh Stream, and a short fire fight broke out. To avoid fighting a long battle, the commander of the 2nd Battalion decided to pull back, and made preparations for a frontal assault on the next day. On the morning of 17 October, two rifle companies of the 2nd Battalion returned to the bunker system they had found the previous day, but they were defeated by the VC 271st Regiment which had set up an ambush in anticipation of the American attack.First Battle of Loc Ninh
