This is not an official USMC combat operations page, but our personal attempt to recover as much info as we can about the operations participated in by M Co. 3rd Battalion, 5th Marines in Vietnam. We will be posting recollections and pictures (when available) sent in by Marines and FMF Corpsmen who participated in Operation UNION and UNION II.  Comments are from informal emails, phone calls, and other correspondence. All related pictures and information is greatly appreciated.

Operation UNION and UNION II
Que Son area, Republic of Vietnam, 25 April to 5 June 1967

Throughout this period, the 5th Marines (Reinforced) was assigned the mission of destroying the enemy forces, their supplies and equipment. With the initiation of a heavy engagement by a Marine rifle company in the vicinity of La Nga (2), the 5th Marines deployed to exploit the contact. Unable to disengage while being subjected to relentless pressure, the 21st North Vietnamese Regiment finally made its stand at the hamlet of Phouc Duc (4). 

For four days commencing 12 May, 5th Marines attacked the fortified enemy positions.  Valiantly withstanding heavy enemy mortar barrages and repelling fierce enemy counterattacks, the Marines shattered the entrenched enemy. Operation UNION II was launched on 26 May with a helicopter-borne assault to destroy the withdrawing remnants of the 21st North Vietnamese Regiment.  

UNION and UNION II inflicted over three thousand enemy casualties and eliminated the 2nd North Vietnamese Army Division as a combat force to be reckoned with for many months. The entire 5th Regiment received the Presidential Unit Citation awarded by President Johnson.

The first photos of the first med evac's at the start of Operation UNION (that was when the M-16's didn't work!). The fighting was so heavy and intense that it was 4 days before any wounded could be brought out. Gen. Westmoreland took one look, and gave up his helicopter to be used for evac's.~"Doc" Vic Perez

"Denny"
M/3/5, Dec 66-Jun 67
(A memoir of Denny Dinota submitted by J.R. McElroy, Jr.)

Denny Dinota joined the Marine Corps at age seventeen. Here he was, in combat for the first time as a twenty-five year old Staff Sergeant. He had missed going to combat as a rifleman. There just hadn't been a war and he couldn't do anything about it. He was with Mike Company, 3rd Battalion, 5th Marines for six months. Here are some of my memories of Denny.

In his first large operation, Operation DESOTO, Staff Sergeant Dinota distinguished himself as a platoon commander by ensuring the destruction of a series of six mutually supporting enemy bunkers connected by a number of trenches. While sprinting over open terrain to direct fires of machine guns and rocket launchers, he marked enemy positions for air and artillery. His skills were obvious. He knew how to look out for his men and he could lead; and, his knowledge of infantry weapons, support arms, offensive and defensive tactics, and map reading was superior.

Denny received a meritorious promotion to Gunnery Sergeant just prior to to Operations UNION and UNION II and became Company Gunnery Sergeant. Additionally, he served as Company Executive Officer in the field. During Operation UNION, Denny was continually picking fragments from his red, largely swollen left arm. It was obviously infected. He wouldn't turn himself in and wasn't about to leave in spite of the Battalion Commander's expressed concern to me. It seemed combat to him was both a mental and physical challenge. He fought aggressively, but with control. Denny constantly checked lines at night for security. He was keenly aware of ammo, water and supply requirements and kept up with them at all times. On the move, his major effort was to detect ambushes or surprises.

In mid May after an all day encounter with NVA forces, the company set up nighttime defensive positions. At dusk and into darkness, Gunny Dinota had the right flank of the company lines moved back and new positions dug in. At midnight when the company again came under intense NVA mortars, the bugles sounded and a ground attack followed. The main thrust of the NVA ground attack was where Denny had moved the lines and the enemy advanced right into our machine guns, rifles and M-79s firing down their flank. The NVA assault met with disaster. Several days later, Gunny Dinota became aware of two Marines (found to be mortally wounded) in front of the company perimeter in danger of being captured by the NVA. Amid mortars and small arms fire, he quickly organized and led a squad along a trench through an exposed rice paddy. From there the Marines and their weapons were evacuated back to the company perimeter without a casualty.

Throughout these operations Denny possessed a unique ability to quickly and accurately diagnose the strength, disposition and size of an enemy force. He was a superb leader who looked out for his men. These are a few of my memories of Denny. After Denny was transferred from Mike Company, he received a Battlefield Commission in August.~J. R. McElroy, Jr.

I served with Mike Company from about Dec. '66 through Operation DESOTO - end of Jan. through Feb. '67, and through Operations UNION and UNION II spring and summer of '67. Transferred out after ADAIR to DaNang area the end of June early July (?).

Operation UNION and UNION II

I was platoon sergeant and platoon commander of 2nd platoon (and another platoon for a short while), and was the company gunny during UNION and UNION II.  During UNION and UNION II 3/5 engaged in three pretty big battles. Mike Company was up front in all of them. 

On May 12-13, we got what you might call Banzai-ed after an all day fight. We were out-numbered by several hundred. The NVA did manage to break through our line, but died for their efforts. During times like that you don't see officers and staff getting up running about the area giving directions and displaying leadership and all that stuff. You couldn't stick your little finger in the air without getting it shot off. The skinny kids in the fighting holes did what they were trained to do, and did it.

My point man was the first to come upon what was left of Fox 2/1. He first came up on a Marine machine gun squad still around their gun. Because they still had their gun means to me that they fought until they died, and the enemy never got the gun. About 10 yards further, we came upon the rest of the company. They were on line, halfway across a rice paddy, dead. Most of them anyway. Very few emergency evacs. Officers still had their radio hand sets to their ears. All very surreal.

During that time earlier in the day as we were losing people we received replacements from the rear. They were cooks, bakers and candle stick makers who probably earlier in the day were fat and happy and getting a sun tan. Boy, were they in for "It." Anyway, when the sun came up in the morning we were all in a daze. I didn't count the dead NVA, but the rumored number was 167  that they left on the field. We don't know how many they managed to take with them.

Combat experience is all relative to each individuals own experience. During January and February we had been in some pretty good scraps. I knew I had experienced combat. I could have left the war and felt satisfied. The company had seen the elephant. On May 12-13 and the rest of Union I realized that I (we) hadn't seen shit. And it never stopped for six weeks.

About a week after Union we were still in the field on yet another operation. I was standing at the bottom of a hill when a company runner came running down and with excitement told me that I was getting transferred. I felt bad about leaving, but at the same time I couldn't believe that I just might get out alive. As I started up the hill to the C.P. Bill Vandegriff stopped me to tell me thanks. I'll never forget that. Coming from a man like Vandegriff it was like getting the Medal of Honor.

There is no way to describe what goes on, and everybody while going through the same experience remembers it differently. Strange life we have here.~Denny Dinota

1 May 1967

About 10-10:30 a.m. on May 1, 1967, I was shot while on an operation. I was carrying a radio for Lt. Johnson of the 3rd Platoon.  Around 11 a.m. I was picked up with some other Marines and medevaced to a field hospital where they removed the bullet and tended to me and others.  

Just after dark, two helicopters came to take us to the hospital ship, the USS Sanctuary. The helicopter I was on was equipped to hold stretchers, and was loaded with all Marines on stretchers. The other helicopter took Marines on stretchers, and also those who could walk. 

A short while after we took off, I saw tracers going up and our window gunners firing down. I also saw the muzzle flashes from the gunner on the other chopper, so I know they also received fire. This lasted only a short time. We continued out over the ocean to the Sanctuary. The helicopter I was on landed on the Sanctuary first. While we were being unloaded, the other helicopter circled. Before the helicopter I was on took off, the other one crashed into the sea. 

A few days later, some of those from that helicopter were recovered from the ocean by sailors from the Sanctuary. I always thought that the details of that tragedy had been passed on to relatives. I did not know it was listed as mechanical failure till I saw it on your memorial page (May 1, 1967 Memorial page). I believe that it was due to enemy fire.~Kevin Kelly

Served as Forward Observer with Mighty Mike from March through September 1967. Then served with 3/5 Hdqtrs. until January 1968. Was proud to serve with Captain McElroy; Gunny Denny Dinota and a bunch of other great Marines during Operation UNION, UNION II; COCHISE; SWIFT; and several smaller operations. Semper Fi,~Byron

Hill 65 was the base camp we established at the end of Operation UNION

I don't remember a whole lot about UNION. I was with H&S then and was keeping track on casualties. I was wounded about 2 weeks or less after it commenced. Col. Esslinger and I were wounded on the same blast. Ran into Col. Esslinger at PI after I returned in '68, I assume he may have been medically retired, he wasn't there long. Helluva guy, always liked him. Semper Fi~
