Hill 119: Defending a Reconnaissance Marines’ OP, Vietnam, 1969–70
"You cannot read Fallon’s book without gaining tremendous respect for those Marines who fought with courage and skill and served honorably where their country asked them to. I strongly recommend Hill 119 for those who wish to gain additional insight into the Vietnam war and how it was fought." — W.E. Boomer, General, U.S. Marine Corps (Ret.)
The Marines and Corpsmen of Delta Company, 1st Reconnaissance Battalion, 1st Marine Division were surrounded by the North Vietnamese Army (NVA) for six hundred days in 1969 and 1970 during the Vietnam War. Hill 119 is a rise on a finger of land. Located twenty-eight kilometers south of Da Nang that overlooks the Thu Bon River Basin and Go Noi Island. The hill provided Marines with an excellent 360-degree view of the region that was known as “Indian Country," and so it was occupied as an Observation Post. Its original mission was to support Operation Taylor Common, Task Force Yankee's push west into Gen Binh's Base Area 112.
The Observation Post produced immediate results with supporting arms inflicting casualties on the NVA. Based on its immediate and enduring success as a tactical obstacle for the NVA, the OP became a key piece in the defense of the Da Nang Vital Area. The Marines called supporting arms every day and every night. They rained fire down on the North Vietnamese Army (NVA), and killed over a thousand enemy fighters. They posed such a threat that Gen Binh assigned his elite T89 Sapper Battalion to eliminate the Recon Marines on Hill 119. Throughout this period, as part of a six-man team, each Recon Marine would run multiple adrenaline-filled patrols deep into enemy territory in small teams for six weeks and then serve for two weeks on the OP. Despite its danger, the Marines considered OP duty as a relaxing break.
This first full account of Hill 119, written by historian Michael Fallon, who served as reconnaissance patrol leader on Hill 119, is based upon firsthand accounts from the Recon Marines, carefully cross-referenced with patrol reports and command chronologies. It covers the Marines’ experiences in the bush, on the hill, and in the rear. The role of new battalion commanders, with their changing tactics is the six officers impacted the battalion with their personalities as well as their planning and execution of the changing missions with the always changing enemy situation, from classic Keyhole snoop and poop patrols to aggressive Stingray patrols, designed to inflict casualties.

This book was a revelation. It gives a unique glimpse into life with the much touted 1st Recon Battalion in Vietnam 1969-1970. I knew many of the young officers mentioned here some ten to fifteen years later when they were field grade officers.
I was surprised at finding out that Recon Marines did not have any familiarity with mortars and machine guns in terms of school training or being staffed with Marines with those MOS's. The officers and SNCO's OJT'd the junior enlisted in these weapons.
Amazed at the fire control boundary issues. So many enemy got away. NVA astutely exploited unit boundary seams. OP 119 was an island in the sky surrounded by NVA. Pretty amazing the NVA took so long to finally attack the position.
So the author wrote this after a career in the Marines as a colonel but he really captures the feel of company grade officers. This was war fought and planned by the company grade. Surprised the S-3A is interacting with the lieutenants more than the S-3, a major.
Just an intense optempo. Hill 119 was a nice rest in some sense. Once Vietnamization commenced 1st Recon Bn really went to work with the Stingray Concept. An economy of force operation to cover the withdrawal of large infantry units.
The GCM of 1stLt Lee was a surprise too. Had not heard of this incident. A total disgrace IMHO. Thrown to the wolves for the perception of political expediency. But he prevailed. However, denying his civilian counsel government transport to theater was a low blow.
Also amazed that the author does not mention the death of LtCol Leftwich in the book. There's only an endnote mentioning it.
A long read that gives you the strategy and tactics of the big picture as well as the daily routine at the platoon level. Well worth it. I might just buy it.

Hill 119 was a barren rise on a finger of terrain, lying south of Danang in South Vietnam, with a 360 degree view of so-called ‘Indian Country’. Delta Company, 1st Recon Battalion, 1st Marine Division manned an Observation Post (OP) on the hill for 600 consecutive days in 1969 and 1970. They also took part in up to week-long recon patrols; while on the hill, they called in artillery and air-strikes on enemy movements. The enemy was the Viet Cong and the North Vietnamese Army, and particular, 2nd NVA Division’s T89 Sapper Battalion.
Michael O. Fallon begins his narrative with a geo-strategic overview for the year of ‘Vietnamization’, 1969. He homes in on Vietnam, relating how the Americans created a base on Hill 119 to cover the area 15 miles south of Da Nang known as Go Noi Island, sandwiched between two rivers, which was a Viet Cong and NVA stronghold and a staging area for attacks on Da Nang. The US also designated the island as a Free Fire Zone and conducted occasional sweeps to clear out the enemy. The small contingent of Marines on the hill was exposed to the elements, the rain and especially heat, so that Fallon, who served on the hill, remembered it as ‘a hot rock in Vietnam’.
With their OP established, the marines conducted morning patrols to check the protective wire and to carry out after-action assessments. They also set ambushes, interdicted enemy movements, recovered downed pilots when necessary, investigated villages and caves, and captured prisoners for interrogation. All that activity sometimes led to direct encounters with enemy troops, but more often they spent their time and energy avoiding enemy booby traps. They also made continuous improvements in the base for defence and living. By November 1969, an observation tower dominated the hill, with mortar pits and other bunkers dotted around to form an overlapping defensive structure. The OP’s primary function was to monitor enemy movements and call down artillery fire or airstrikes on them. Fallon notes that the Measure of Effectiveness (MOE) was the body count of enemy dead. The OP’s mission was aided by the introduction of a Secret Integrated Observation Device, which led to greater enemy casualties.
Of course, the NVA leadership found the OP more than an irritant, but their probes into the security of the hill was met with M79 HE rounds, and mortar, sniper, and machine gun fire. Nevertheless, an enemy assault on the hill seemed inevitable. One such plan was foiled by the Marines in early 1970, but in August, the assault came only to be repulsed with intense fire from the hill and covering artillery fire. Political circumstances, however, would succeed where direct assault could not, with the Nixon administration’s drawdown of US forces, which included the Marines. All the NVA had to do was wait out the Americans, and they would leave, which is exactly what happened. It was not just the enemy in the open that the Marines would have to worry about: Fallon argues that then men on Hill 119 could never quite come to grips with the local civilians and their needs and requests. This was exemplified in their dealings with a seemingly innocuous one-armed woman from a local village who visited often and who, many years later, was confirmed as a local Viet Cong leader. The clumsy interactions with locals led to the killing of another civilian woman, which ended in a court martial for the Marine sniper involved, though he was finally acquitted. In March 1971, the Marines left Hill 119 for good, destroying their defences behind them. The still bald hill slowly returned to nature.
Hill 119 is a nuts-and-bolts look at a small slice of the Vietnam War. Fallon notes that his book was written for today’s Marines and to honour the veterans who he fought alongside. He conducted one-hundred interviews and checked those against documentary sources and tactical maps, some of which he reproduces in the text. He leaves nothing out, including a constant flow of administrative and organisational changes, discussions of tactics, narratives of operations, and a detailed account of a court-martial. That attention to detail, some of which could easily have been transferred to footnotes, created an uneven account, with passages of concentrated action separated by long sections of routine and often humdrum events – much like the War itself by all accounts. The chapter structure is also somewhat mechanical, opening with the wider political context then zooming into Marine activities surrounding Hill 119. The overall effect is not as monotonous as it might sound, but there is so much detail included that the book grinds rather than flows. That said, there is much to admire in Fallon’s rigorous research and writing, and it is fair to say that he achieved his purpose. Readers of the Vietnam War will devour this book, which provides a valuable insight into what the US Marines on Hill 119 did and how they did it.

Hill 119: Defending a Reconnaissance Marines’ OP, Vietnam, 1969–70 is an extremely detailed account of the Marines and Corpsmen of Delta Company, 1st Reconnaissance Battalion, as they manned an observation post near Danang during the Vietnam War. Like a James Michener novel, the account starts with a description of the surrounding infrastructure constructed during the French colonial period: roads, railroad tracks, dams, and canals. All of these features would play a part in the daily operations of the Hill. With two higher hills in close proximity, it was only through aggressive patrolling and regular night ambushes that the men of Hill 119 were able to maintain their presence and enable another group of Marines to conduct vital day-and-night surveillance over a valley that was an NVA infiltration “highway.”
The author, who spent considerable time as the commander on the hill, spares no one by offering an honest appraisal of both the valor and shortcomings of the people who manned the Hill and the supporting 1st Reconnaissance Battalion. Most chapters start with a short paragraph on what was happening in the U.S. at that time and in the conduct of the war, to provide necessary context. Even though Hill 119 was an isolated and occasionally beleaguered outpost, events on the Hill would eventually be felt not only in the larger theater of the Vietnam War but also in the United States.
The author uses an extensive collection of maps and diagrams, many of which he and others used during the war. An extensive glossary is provided, ensuring readers at any level of interest in military history do not get lost in the blizzard of jargon and acronyms from a conflict that happened over 55 years ago. This book will be of interest to military history enthusiasts, Vietnam veterans, or anyone seeking a deeper understanding of the U.S. military's final days in the Vietnam War.
