ance available. Meanwhile, a source of supply and support for the Viet Cong had been eliminated.
By 14 January the forces of the 1st Division were starting grad-ually to wind down CEDAR FALLS. However, before they did, the Blue Spaders of the 1st Battalion, 26th Infantry, moving to the northwest of Ben Suc, uncovered one of the more highly developed and strongly built enemy complexes to be found in the area located less than one kilometer from the Saigon River. This is the descrip-tion of it contained in the after action report of the Big Red One's 2d Brigade:
Building #1 was approximately 9 feet wide by 18 feet long and 10 feet below the surface of the ground. The building had cement on all four sides and flooring about 5 inches thick. The only overhead protection was afforded by sheets of tin. On the northwest corner was a bunker with no overhead protection. Beds and tables were on the floor.
Build #2 was approximately 9 feet wide by 12 feet long and 10 feet below the surface. It had concrete identical to Building #1. Overhead cover over one-half of the structure consisted of 5 inch logs and 3 feet of packed dirt. There were no fighting positions located near the building and beds were located on the 1st floor and on top of the overhead protec-tion. Building #3 and #4 were exactly identical to building #2.
Bunker #5 located north of the camp and connected by tunnel to build-ing #3 had overhead protection of 5 inch logs and 3 feet of packed dirt. There were four firing apertures, each 2 inches high and 4-6 inches wide and each could cover an area over 100m wide to the front.
The second level tunnel going north was made so that at every 10-15m it came to a dead end; and a trap door on the floor connected with a tunnel which went down, around and back up to the other side and on the same level with the fake dead end. There were two small holes in the dead end permitting one man to observe and fire through the tunnel.
On 17 January the 2d Brigade ended its participation in CEDAR FALLS. By 18 January the 3d Brigade had withdrawn. Task Force DEANE terminated CEDAR FALLS on 25 January while the 1st Squad-ron, 4th Cavalry, continued road security in the triangle for the departing engineer work parties. At midnight, 26 January 1967, the operation came to a close.
