~ 18th Engineer Brigade History ~

The history of the 18th Engineer Brigade begins on 29 July 1921, when its predecessor, the 347th Engineers (General Service), was constituted as an organized reserve unit. The unit was ordered into active military service on 6 May 1942 at Camp Claiborne, Louisiana.

On 1 August 1942, the unit was reorganized and redesignated as the 347th Engineer General Services Regiment. The Regiment deployed to England in February 1944. It entered combat in France on 29 June 1944 and participated in the Normandy, Northern France, Rheinland and Central Europe campaigns of World War II , earning its first Meritorious Unit Commendation. After V-E Day, the Regiment remained on occupation duty in Germany until it was inactivated on 1 June 1946.

On 15 June 1947, the Regiment was reactivated in the organized reserves headquartered in Salt Lake, Utah, and remained there until it was again inactivated on 16 March 1949.

On 25 October 1954, the 347th Engineer General Services Regiment was redesignated the 18th Engineer Brigade and activated as a Regular Army unit at Fort Leonard Wood, Missouri, where it remained until inactivation on 26 March 1963.

The 18th Engineer Brigade was reactivated on 16 July 1965 at Fort Bragg, North Carolina and prepared for deployment to Vietnam. From September 1965 until December 1966, the Brigade oversaw all U. S. Army Theater engineer activities in Vietnam. In December, 1966, the U. S. Army Engineer Command, Vietnam (Prov) was created and the 18th Engineer Brigade became responsible for engineer support in the I and II Corps Tactical Zones. The Brigade Headquarters was located at Dang Ba Thin. Many of the Brigade's projects stand out as exceptional engineering feats. Among them was the contruction of the critical Hai Van Pass, a job attempted by many but accomplished by the 18th Brigade, and a storage area in Cam Ranh Bay, two years in construction and enclosing 191,700 square feet. The brigade has also been actively engaged in road building and land clearing, as well as numerous civic action projects. The accomplishments of the 18th Engineer Brigade have not only contributed significantly to the success of combat forces in Military Regions 1 and 2 but have provided valuable assets to the future development and growth of South Vietnam. On 20 September 1971, the Brigade was inactivated. Over the six years the Brigade served in Vietnam, it participated in 14 of 17 campaigns, earning four more Meritorious Unit Citations.

On 21 October 1977, The 18th Engineer Brigade was reactivated at Karlsruhe, Germany. For the next 15 years, the Brigade served as the principal construction brigade for the United States Army, Europe and 7th Army. During this period, the Brigade performed numerous construction, rehabilitation and renovation missions in military communities and training areas throughout USAREUR. Most noteworthy were the massive range upgrade of the Grafenwohr Major Training Area in the early 80's and the construction of the Range 23 complex at the Wildflecken Major Training Area in 1989 and 1990. Additionally, the Brigade was responsible for providing topographic support to the European Theater.

In 1990 and 1991, during Operations Desert Shield and Desert Storm, the 18th Engineer Brigade provided rail and sea deployment support to the VII Corps and, in addition, deployed a Combat Heavy Battalion and Topographic Company to support VII Corps operations in Southwest Asia. In April 1991, the Brigade Headquarters, along with a subordinate Combat Heavy Battalion, deployed to Zakho, Iraq in support of Operation Provide Comfort. While there, the Brigade coordinated all engineer efforts of a Joint and Combined engineer force providing construction and relief support to the Kurdish refugees. The 18th Engineer Brigade was awarded the Joint Meritorious Unit Award for its action during Operation Provide Comfort. As part of the reduction of forces in Europe, the Brigade was inactivated on 15 October 1992.

On 18 Oct 2002, the Vice Chief of Staff of the Army approved the USAREUR and 7th Army Concept Plan to activate the Theater Army Engineer Brigade (TAEB), culminating a process began in 2000. Today, the 18th EN BDE (TA) marks the return to service of the only active duty TAEB.

The U.S. Army is the only branch of the service with UNBROKEN lineage to the Revolutionary War. When the Revolution ended, all services were disbanded EXCEPT for a unit of Artillery left to guard U.S. and captured British weapons stored at Ft. West Point. These artillerists were still active Army. Later, after the War of 1812, this unit was used as the core of instructors who founded the U.S. Military Academy at the same fort - West Point. This artillery unit, however, has always been a working unit of the Army, participating in every war. They have been moved from command to command and the name has been changed several times, but their lineage is UNBROKEN. In the Civil War, for example, they were Battery A, 4th U.S. Artillery.

Unofficial Army histories (like Russell Weigley's and Gen. David Palmer's) both list the birth of the U.S. Army as being 1789 BUT These are not "official" U.S. Army histories. The only official history is published by the U.S. Army's Center for Military History in a series of volumes. Those volumes also contained "Lineages and Honors" which gave complete details of the above. Some samples of these lineages are posted on the CMH's echo web site attached to the main U.S. Army web site.

~ The 18th In Vietnam ~
Jungle Eaters & Rome Plow Companies
Sword


Just 20 miles north of Saigon, the Iron Triangle was a near impenetrable guerrilla stronghold where the jungle protected a labyrinth of enemy staging areas and resupply points. Operation Cedar Falls, the first in a series of U.S. offensives in 1967, was about to violate this sanctuary. After six infantry, armor and cavalry battalions sealed the 40-square-mile area on January 9, 1967, the 11th Armored Cavalry Regiment (11th ACR) attacked west from Ben Cat. Engineers atop unusual-looking bulldozers rode alongside and sometimes preceded the cavalry troops. When the dozers formed into echelons and moved straight into jungle so thick that it could stop a tank without to much difficulty, the cavalrymen's expressions quickly changed to astonishment. The specially modified D7E bulldozers were known as Rome Plows, a name borrowed from the special shearing blades they carried. The process that brought the plows to the Iron Triangle began in September 1965. Having observed the VC tactics for the past year, General William C. Westmoreland, commander of U.S. Military Assistance Command, Vietnam (USMACV), told his staff to develop options for jungle-clearing to expose VC base camps and infiltration routes. Experience had shown that conventional infantry sweeps merely displaced the enemy temporarily. When the soldiers left, the VC returned.

Clearing the jungle would remove the sanctuary. Unfortunately, there was no established doctrine or procedure for doing this. The search ended when the Department of the Army recommended the Rome Plow, already in use in the United States to cut fire breaks. The system used a D7E, or equivalent heavy bulldozer, fitted with a reinforced cage to protect the operator while heavy tubular steel skeleton extended from the cage to the front of the dozer to shield the engine. The heart of the system, however, was a special oversized blade produced by the Rome Plow Company, originally located in Rome, Georgia, which later moved to Cedertown, Georgia where it remains in operation today. Romes K/G blade was wider than the dozer, nearly as tall as a man, and weighed more than 2 tons. Mounted at a 30-degree angle to cast debris aside, the blade rode six inches above ground level to cut trunks but to leave root systems intact to prevent erosion. Besides its extremely sharp slicing edge, the spade curved more than the conventional earth-moving blade and a reinforced steel stinger protruded from its left side. The driver used the stinger to weaken large trees by stabbing them repeatedly and twisting the tractor. A REPRESENTATIVE FROM THE Rome Plow Company arrived in Saigon with the first six blades in late summer 1966. Units of the 45th and 159th engineer groups trained with the equipment and conducted operational test at Long Binh and Pleiku. Although weather, terrain and ground slope affected cutting, the plows cleared about six acres per hour.

As the number of plows in-country increased, they gained an outstanding reputation, and request soon overwhelmed capacity, everyone needed Rome Plow support. Before years end USMACV ordered 50 more plows. Forty-five Rome Plows and nearly 500 conventional bulldozers supported Operation Cedar Falls, the two phase, two-division offensive. For three weeks while the cavalry scoured the area, plows destroyed the base camps, tunnels, supplies and VC training camps. Surprised and overwhelmed, the VC generally chose to run, but lost with 700 killed and more than 200 captured before they could disengage. Cedar Falls provided the opportunity to develop dozer-infantry tactics. The 1st Division and the 79th and 159th Engineer groups established control centers and several clearing teams that operated simultaneously in four separate zones. Each team used two Rome Plows, six bulldozers, and was supported by a platoon of infantry. The joint teams discovered that the dismounted infantry was unable to keep up with the plows and thus could not provide the Engineers with effective fire support. Mounted infantry, it was discovered, could operate close to the plows and rush immediately to the front or flanks during and engagement. The personnel carriers also protected the infantry from falling trees, anti-personnel mines and snipers.

Once dozer-infantry operations were standardized the use of mechanized security forces, casualties among Rome Plow operators from enemy action decreased significantly. The second and larger phase of the offensive, Operation Junction City, began in War Zone C on February 22 and lasted until mid-April. Rome Plow support for Junction City closely mimicked that provided during Operation Cedar Falls. The 65th Engineer Brigade conducted combat land-clearing operations, cleared landing zones and three C-130 capable airfields, and established two Special Forces base camps. Following the successful operation, Lt. Gen. Julian J. Ewell, later commander of II Field Force Vietnam (II FFORCEV), called the Rome Plow the most powerful tool we have in frustrating and defeating the Communists. The arrival of three Rome Plow platoons, or teams, during the summer of 1967 accelerated the rate of landclearing. Each team had one officer and warrant officer, 62 sergeants and enlisted men, and 30 plows. The newly formed 20th Engineer Brigade two of the teams to support the II Field Force.

The remaining team went to the 18th Engineer Brigade supporting the I Field Force. Cutting operations normally followed two-month cycles with 45 days in the field, followed by a 15-day maintenance stand-down. While cutting plows often ran 12 hours a day before retiring to night protective positions shared with security platoons. The base moved every five to seven days. Tactics evolved throughout 1967. After planning between engineers and the support commander, the area to be cleared was usually prepped by artillery, mortars and tanks before cutting began. Plows and conventional dozers then formed in echelon formation and cut a perimeter around the working area. Keeping the lead plow on a correct course in the jungle was a problem until the teams incorporated radio contact between on orbiting helicopter and the lead plow. With a defined perimeter protected by security forces, the helicopter departed and the Rome Plows cut concentric paths toward the center of the area. While they worked other bulldozers pushed the debris, or slash, aside so that the mounted infantry could maintain contact with the plows. Rome Plows used three basic types of cuts: area, road and tactical.

Area cuts were directed at known or suspected enemy locations, with the primary aim to expose guerrillas to observation and interdiction. After plows slashed broad swaths across infiltration routs, electronic sensors and aerial observation harassed the VC. Road cuts eliminated likely ambush sites by clearing 100 to 300 meter tracts of jungle that ran close to highways. While less than exotic than other missions, road cuts were particularly important since they enabled commerce to increase and provide greater mobility to the larger truck-oriented Vietnamese Army. This method saw wide application in Military Region I in the north, where 75 percent of the cleared land became farms. Lastly, Rome Plows used tactical cuts to support combat operations. This mission included clearing landing zones, base camps and security zones around villages and forts, and often involved elements of both area and road cuts. The tactical cut, not surprisingly, was the most hazardous operation for Rome Plow operators. Although Engineers solved many problems during 1967, two significant impediments hindered land-clearing operations, natural obstacles and maintenance. In addition to snipers, mines, collapsed tunnels and hidden bomb craters, drivers faced the daily challenge of the jungle itself. Mahogany trees 200 feet tall fell on top of the tractors, branches penetrated protective cabs, and there was always mud or dust and temperatures that could exceed 130 degrees. Then there were the snakes, insects and, worst of all, bees that often brought cutting to a halt. Many operators became causalities before crews discovered that green smoke helped disperse the swarms. Other varieties of smoke were ineffective. Bees produced one third greater number of casualties among Rome Plow units following mines and night mortar attacks. USMACV reorganized the teams into land-clearing companies late in 1968, each with 163 men and a maintenance platoon. Despite this, operators still performed most in-field maintenance and showed a remarkable ability to keep the machines running.

Their effectiveness resulted in the formation of the Army?s first land-clearing Battalion in January 1969, the 62nd Engineer Battalion (Land-Clearing). Based at Long Binh, the battalion absorbed the 27th and 86th land-clearing companies into the 60th and the 501st companies and formed a third dozer company, the 984th. The battalion also had an all-important heavy maintenance company. Assigned the mission to support II FFORCEV, the battalion allocated one company per combat division. In I FFORCEV, the 18th Engineer Brigade organized its Rome Plows differently to deal with more restricted terrain and unreliable road network. Instead of a battalion, the 18th deployed one of its three land-clearing companies to each of its three engineer groups. In mid-April 1970, Rome Plows led American and Vietnamese units into Cambodia. The dozers opened roads, cleared airfields and bases, and uncovered enemy camps and facilities on both sides of the border. When President Nixon ordered their withdrawal on June 30, Rome Plows had already cleared 1,700 acres of jungle, performed numerous mine-clearing operations, and destroyed more than 1,000 VC structures. Meanwhile several land-clearing companies were standing down as the number of U.S. personnel in Vietnam decreased. As each company deactivated, its equipment went to a Vietnamese engineer unit. Vietnamization of the land-clearing war had begun in January 1969 when USMACV commander General Creighton W. Abrams approved the buddy system to place ARVN units under U.S. sponsorship for Rome Plow training.

The 62nd Engineer Battalion incorporated 75 members of the newly formed Vietnamese 318th Land-Clearing Company on December 15, 1969, for intensified, one-on-one training. Despite language and experience problems, the Vietnamese showed exceptional aptitude with the powerful bulldozers. One month later, Vietnamese operators undertook missions north of Tay Ninh with U.S. engineers riding on special buddy seats in the plow cabs. After conducting ARVN-only operations in May and receiving more equipment, the Vietnamese 318th Land-Clearing Company became operational on July 1, 1970, under Captain Nguyen Van Tich, a graduate of the U.S. Army Engineer School at Fort Belvoir, Virginia. The 62nd Engineers also trained the ARVN 218th and 118th land-clearing companies. One company was assigned to support each of Vietnams three military regions. Vietnamese operators gradually relieved the U.S. land-clearing units until December 1971 when the last U.S. Rome Plow Company deactivated.

The men who operated and maintained the plows, as much as the equipments design, gave the Rome Plow it's well-deserved reputation as one of the most innovative and effective weapons in Vietnam. These dedicated soldiers daily faced the dangers of combat and refused to yield to snipers, mines, exhausting temperatures or grueling hours fighting jungle tree by tree. They also suffered extremely high casualties, two of every three men assigned to a Rome Plow Company became casualties. Despite these adversities, or perhaps because of them, Rome Plow crews consistently had the higher rate of voluntary extension in Vietnam of any group of Engineers. These were the men who made the Rome Plow synonymous with Land-Clearing and Jungle-Busting. Written by: Lawrence M. Greenberg and published in the magazine "VIETNAM" February 1991

~ The Lines of Communication Program ~

In the Vietnam War, as in all wars, transportation was a big factor in military operations. The desire of the United States to improve political and economic life in South Vietnam was an added incentive to make every part of the country easily accessible to commerce and government. Strategic, tactical, and logistic mobility were essential ingredients of military success; the ability to move enough units, men, equipment, and material where they were needed and when they were needed was the index of such success. Since most existing land lines of communication in the Republic of Vietnam were either incapable of supporting American military vehicles or were subject to continuous enemy interdiction, it was necessary at first to depend heavily on water and limited air transport to provide logistic support.

The plan to move extensively by water encompassed not only the major ports of Saigon and Cam Ranh Bay and the shallow-draft ports of Qui Nhon and Da Nang, but also entailed the establishment of a series of shallow-draft ports along the coast. Through port improvement it would be possible to capitalize on Vietnam's long coastline for lateral distribution of supplies. As the larger ports developed, supplies could be shipped by water to the smaller ports and then inland by highway or airlift either to the forward support areas being established throughout the country or directly to the combat elements.

When U.S. Army engineers landed in Vietnam in 1965, only two deep-draft ports existed in the entire country-Saigon and Cam Ranh Bay. Shallow-draft port facilities existed at Nha Trang and Qui Nhon, and there were several beaches along the coast over which cargo could be transported from ships lying offshore. Although the Army lacked ships to take advantage of the shallow ports, this lack was offset to some degree by unloading cargo across the beaches. The two deep-draft ports with their severely limited berthing facilities were totally inadequate for handling the volume of American materials being shipped to Vietnam during the troop buildup.

The 497th Engineer Company (Port Construction), the Army's only such company in 1965, estimated the requirements and made plans for both long-range and short-range port facilities throughout South Vietnam, except in I Corps, which received its support from the Navy. Over-all plans called for making Saigon and Cam Ranh Bay into major logistical bases, and Qui Nhon, Nha Trang, Phan Rang, and Vung Tau into minor support bases. As the ports were developed a variety of attendant projects were undertaken in addition to the basic pier construction. Barge off-loading facilities, airfields, ramps for landing craft, and logistical storage facilities were incorporated in the plan.

The greatest single aid in the rapid development of port sites in Vietnam was the DeLong pier. Essentially one version of this pier consists of a 90x300-foot barge supported by eighteen tubular steel caissons 6 feet in diameter and 50 feet long. These caissons are placed in, collars attached to the piers and are pressed into the harbor bottom by pneumatic jacks that are a part of the collar apparatus. Therefore the pier is further jacked up on its caisson legs to the desired elevation above the water surface.

Each DeLong pier provided berthing for at least two ships simultaneously, and use of these finger or T-shaped piers made possible the rapid development of deep-draft ports at Qui Nhon and Vung Tau and expansion at Cam Ranh Bay. The first DeLong pier assembled in South Vietnam was at Cam Ranh Bay. Its installation required the efforts of sixteen men for forty-five days; a timber pile pier of comparable dimensions would have required at least six months' work by a platoon of forty men with special equipment. DeLong piers were emplaced as quickly as they became available.

A wide spectrum of engineer activity accompanied the development of port facilities at Cam Ranh Bay. An 800-foot rock causeway and 80-foot bridge span previously discussed were constructed to provide access to the first DeLong pier, a large cargo-handling area was prepared, and a roadnet capable of supporting the inland shipment of cargo was build. The first tactical airfield with a runway of expedient surfacing to support jet fighter aircraft was constructed, and along with it a 400-foot timber jetty to assist in pumping fuel from the piers to the air base. Eventually Cam Ranh Bay was served by four DeLong piers as well as facilities for offloading shallow-draft vessels. In addition to being the largest logistical storage area in the republic, Cam Ranh Bay became one of the largest and most effective ports in Southeast Asia.

Dear Joe:

I am a 35-year-old son of a Vietnam veteran. My Dad, Jerry D. Prigmore, who is my hero, my role model and one of my best friends, enlisted in the Army and served in Vietnam in 1966-67 in the 18th Engineer Brigade, and I believe it was the 299th Engineers, at Dak To and Pleiku.

I’ve always been enormously proud of my Dad and all the other Vietnam vets. Because of my interest in the war, I knew a lot of things that your site re-confirmed – i.e., the U.S. military did not lose the war, Tet was an enormous defeat for the North and V.C., etc. I also learned some things I didn’t know – Dad has told my brother and me quite a few stories, but didn’t mention the Rome Plow, which I imagine may not have seen as much use where he was. I’ll have to ask him about it!

I think part of my pride and gratitude stems from the fact that I myself never served. Although I always loved and respected the military, after giving up a dream of flying in the Air Force, I went to college, started a family and a career, and that was that. I owe it to our vets that I had that option, and although regrets serve no purpose, I have to say that with the Samuel Johnson quote you provided, I have finally found something that perfectly sums up the feeling of my life’s one true regret, that is, not having served. I try to make up for it by honoring those who did, and living up to their ideals, as honestly and honorably as possible.

I am glad that you have exposed some of the most pernicious myths of the war. I know that the vast majority of persons my age are grateful to the Vietnam vets, but I wish they had more facts. The World War II generation is now called “The Greatest Generation,” and they are rightly honored, but I believe the true Greatest Generation is like a stream of honor meandering through our nation’s history and includes all those that believe in something higher than themselves, whether God, Country, or just the guy next to them, and put that belief into action at the risk of their own lives, whether at Brandywine, Gettysburg, Tarawa, Pork Chop Hill, Khe Sahn, or Fallujah. I also believe that no soldiers have been as brave and pure-hearted and received less of the honor due them than you and your fellow Vietnam vets. I will continue to honor you and will share your site with as many people as I can.

Gratefully
Jerry G. Prigmore
