The 7th Marine Regiment was formed during World War I on 14 August 1917 at Philadelphia, PA and immediately deployed to participate in the occupation of Cuba from August 1917 to August 1919. They returned to Philadelphia in August 1919 and were deactivated on 6 September in the demobilization that followed the war. When the Marine Corps was called upon to provide peacekeepers in the Caribbean, elements of the Regiment were reactivated on 6 September 1933 at Quantico, VA and deployed on Naval ships off the Cuban coast. At the end of the crisis, 7th Marines was again deactivated on 17 January 1934.
With the cloud of World War II on the horizon, the nation expanded the size of the Corps and on 1 January 1941 the 7th Marine Regiment was reactivated in Guantanamo Bay, Cuba and assigned to the 1st Marine Brigade. The Regiment moved to Parris Island, SC before settling in New River, NC. On 2 April 1942, the Magnificent 7th embarked for the Pacific to reinforce units already there to stem the Japanese march towards Australia. On 18 September 1942, after training in jungle warfare in the Samoa Islands, the Regiment landed in the Solomon Islands on Guadalcanal. For four long months the Regiment relentlessly attacked the Japanese defenders and repulsed their Banzai charges and suicidal attacks. Over the course of a hundred fights, the Regiment earned a reputation for courage and daring. On Guadalcanal the heroism of Medal of Honor winners Manila John Basilone and Mitchell Paige, and Navy Cross winner "Chesty" Puller, represented the actions of the Marines of the 7th Marine Regiment.
Arriving in Australia in January 1943, the vast majority of the Regiment suffered from malaria, wounds, or just plain fatigue; but they had accomplished their mission. Though the Regiment went to Australia to train and refit for the coming battles and not for liberty, a grateful population gave them a tumultuous welcome. Again and again the Regiment was called upon to storm the Japanese-held islands in the Pacific. The 7th Marine Regiment fought in such places as Eastern New Guinea, New Britain, Peleliu, and the island fortress of Okinawa. From Guadalcanal to Okinawa, the Regiment had written a history of courage and ferocity in combat.
In the years after the war, 7th Marines continued to serve on far off shores, occupying North China from 1945-1947 and disarming the Japanese troops still stationed in that country and keeping the peace in a China torn by civil war. Upon returning to Camp Pendleton, CA from China in January 1947, the Regiment was deactivated yet again on 6 March only to be reactivated on 1 October. The reactivation was short lived, however, and 7th Marines was deactivated on 1 October 1949.
On 17 August 1950 the Regiment was reactivated, and on 21 September 1950 the Regiment landed as part of the 1st Marine Division in General MacArthur's brilliant stroke to stem the North Korean tide at Inchon, South Korea. The Marines of the Regiment fought in Korea with the same tenacity and bravery that their predecessors had shown on the battlefields of World War II. From Inchon to the Yalu River, at the "Frozen Chosin" Reservoir, and in the long defense of South Korea until the armistice in 1955, Marines of the Regiment wrote further glorious chapters in their unit's history. The Korean War, however, was only the prelude to the long Cold War period that would hold the world on the brink of nuclear confrontation for the next 40 years.
In November 1962, substantial parts of the Regiment embarked for the Caribbean and possible action in Cuba, aimed at forcing the removal of Soviet nuclear missiles pointed at the heart of America. As the crisis subsided, 7th Marines returned to Camp Pendleton, CA. The confrontation with Communism, however, was not finished with the removal of Soviet missiles from Cuba.
In July 1965, the Regiment went into action against the foes of freedom. This time the battleground was Vietnam. On thousands of squad sized patrols, in scores of Battalion and Regimental sized operations, and in fierce Division sized battles such as the TET Offensive, the Marines of the Magnificent 7th proved that they were worthy successors to those who had gone before them. Whether in armed action against the enemy in places like Chu Lai, Da Nang, and Duc Pho, or in civic action with the local populace, the Marines of the Regiment performed magnificently. Through the long course of the war in Vietnam, until they left as part of the American withdrawal, the Marines and Sailors of 7th Marines never wavered from their duty. As the Regiment sailed for the United States in September of 1970, the members of the Regiment were proud of their role fighting against Communist aggression.
During the 1970s and 1980s, the Leathernecks of 7th Marines trained in every clime and place preparing for the moment when they would once again be called to fight the Nation's battles. In August of 1990, shortly after shifting the home of the Regimental colors from Camp Pendleton, CA to Marine Corps Air Ground Combat Center Twentynine Palms, CA, the Marines and Sailors of the Regiment deployed to Saudi Arabia to halt Iraqi aggression against its neighbors in Operation DESERT STORM and Operation DESERT SHIELD. Manning the "Line in the Sand", the Regiment faced the Iraqi invaders. For the attack into Kuwait, the Regiment fought with skill and aggressiveness, overwhelming the enemy. After their victory, they returned to Twentynine Palms in March 1991 with the knowledge they were warriors shaped in the mold of those who had served their Country and Corps before them as members of this elite Regiment.
In August of 1991, 7th Marine Regiment became Regimental Combat Team Seven (RCT-7) due to unique organizational changes that occurred with the addition of 3rd Light Armored Infantry (LAI) Battalion, 1st Tank Battalion and Delta Company, 3rd Amphibious Assault (AA) Battalion. In December 1992, RCT-7 deployed on Operation RESTORE HOPE to relieve famine and return order to Somalia. Over a five month period the Marines and Sailors paid in blood as they worked tirelessly to alleviate the suffering of the Somalian people and to restore order to their ravaged nation. On 13 August 1993, on the eve of the Regiment's 76th anniversary, the Regiment formally marked the return to its original designation by changing from RCT-7 to 7th Marines (Reinforced).
On 8 October 1994 the action cycle began again for 7th Marines (Reinforced) when a crisis situation in Southwest Asia forced the decision to terminate a combined arms exercise in order to prepare for a Maritime Prepositioning Force (MPF) deployment. This high paced contingency operation was titled Operation VIGILANT WARRIOR. Although the National Command Authority did not give the order to deploy the entire Regiment, its advanced elements moved into the Arabian Gulf in response to Iraqi troop movements toward Kuwait. In Operation VIGILANT SENTINEL, from August to November 1995, this sequence was repeated.
In August of 1996, organizational changes designated 3rd Light Armored Reconnaissance Battalion (formerly LAI Bn) and 1st Tank Battalion as separate battalions in direct support of the 7th Marines' MPF mission along with Delta Company, 3rd AA Battalion, who returned to their parent unit.
In the intervening years of relative calm, the 7th Marine Regiment continued to maintain a high state of readiness by continual and rigorous training evolutions. The calm was shattered on 11 September 2001 by a terrorist attack on the World Trade Center, the Pentagon, and an unknown target that resulted in a plane crash in Pennsylvania. With the Nation suddenly involved in the Global War On Terrorism, 7th Marines prepared for its duty. In January 2003, the Regiment deployed to Kuwait in support of Operation IRAQI FREEDOM (OIF) and was instrumental in the "March to Baghdad" with 1st Marine Division in March 2003. Over the next six years, RCT-7 would deploy to OIF five additional times and fight in towns like Ramadi, Fallujah, Al Qiam and Hit in Al Anbar province. Through each deployment, the Marine of the Regiment could proudly display the earned nickname of the Magnificent 7th.
Concurrently, the United States was fighting battles in Afghanistan as part of Operation ENDURING FREEDOM (OEF). Though subordinate battalions of 7th Marines had a near continual presence in the Helmand River valley, the Regimental Headquarters deployed as RCT-7 three times starting in March 2008. Cities such as Marjeh, Sangin, and Lashkar Gah, where some of the heaviest fighting in the country took place, were all under the command of RCT-7. On 31 July 2013, RCT-7 furled its colors as the final RCT to serve in OEF.
Description
On 1 November Chinese elements were identified south of the Changjin Reservoir, and within ten days twelve divisions of the Chinese Communist Forces were identified. In the northwest, strong enemy attacks against the Eighth Army smashed the ROK divisions. Very hard fighting took place near Ch'osan, Unsan, and Tokch'on. While the 24th Division pulled back to Chongju on the west coast, the 1st Cavalry and 2d Divisions fought along the Ch'ongch'on River. In the air over Korea, U.N. pilots were opposed for the first time by speedy Russian MIG-15 Jet fighters.
By 10 November, as the Chinese attacks were abating, the Eighth Army and the X Corps conducted only small-scale operations, and a comparative lull hung over much of the front. By 21 November elements of the U.S. 7th Division occupied Hyesanjin on the Yalu River in northeastern Korea, the most northerly point to be reached by U.S. forces during the war. The ROK Capital Division meanwhile progressed rapidly up the east coast to the Naman-So-dong area. By 24 November the U.N. positions extended from So-dong in the northeast to Hyesanjin on the Yalu, and thence in a southwesterly direction through the areas around Sang-ni, Handae, Yudam-ni, Yongwen, Ipsok, Patch'on and south of Chongju to the Yellow Sea.
Previous to the entry of Chinese forces in North Korea, MacArthur had ordered the Eighth Army and the X Corps on 24 October to attack toward the Manchurian border and restore peace in Korea before the onset of winter. The difficulty of securing adequate logistical support delayed the attack. In the latter part of the month, brief clashes with Chinese troops posed a new threat. The purpose and extent of the Chinese intervention was not yet clear; but in the face of this new opposition, Walker had withdrawn his extended forces back to the lower bank of the Ch'onch'on River, leaving only a small bridgehead above Sinanju.
The fact of Chinese participation in the conflict caused MacArthur to reconsider his plans for an all-out attack to the Yalu River, but not to abandon them. Walker's forces were to move northward through western and central Korea, while Almond's troops were to attack to the northwest to cut the enemy line of communications and give maximum assistance to the Eighth Army. On 24 November the Eighth Army, with the ROK II Corps, launched its planned offensive. For the first twenty-four hours little enemy opposition was encountered, but on the next day enemy troops initiated a violent counterattack against the Eighth Army in the mountainous territory surrounding the central North Korean town of Tokch'on. The X Corps began its attack early on 27 November, and had made slight advances before evening, when a second enemy force, moving down both sides of the Changjin Reservoir, struck at the 1st Marine Division and elements of the U.S. 7th Division.
It was quickly apparent that the bulk of the enemy forces were organized Chinese Communist units. It was now evident to the UN Commend that the Chinese had amassed two large armies in northern Korea, by marching them from Manchuria under cover of darkness and expertly camouflaging them during the day. They were comparatively safe from detection by UN air observers in the rugged mountain terrain, and UN aircraft were prohibited from making reconnaissance flights across the frontier. Thus the strength of the attacking Chinese forces came as a surprise to most of the U.N. Command.
The main enemy effort was directed against the ROK II Corps, which collapsed under the weight of the Chinese assault. As the Communists strove to extend their breakthrough of the U.N. line, Walker rushed his reserve units (the 1st Cavalry Division, the Turkish Brigade, and the British 27th Commonwealth and 29th Independent Infantry Brigades) to the area, but failed to stem the Communist advance. Assaulted by wave after wave of enemy troops, the Eighth Army front withdrew south across the Ch'ongch'on River. These forces, fighting hand to hand with the enemy along the river banks and retreating over reads choked with troops, refugees, trucks, and tanks, suffered heavy losses. The U.S. 2d Division wee assigned to fight a delaying action until other units could retire and regroup in defensive positions near P'yongyang. On 5 December the Eighth Army fell back from P'yongyang to positions about 25 miles south of the city. By the middle of December it had withdrawn below the 38th parallel and formed a defensive perimeter north and east of Seoul.
On 27 November 1950 the Chinese began their offensive against the X Corps, attacking the Marine and 7th Division elements in the Changjin Reservoir area with six divisions. Since the most northerly UN units-the ROK I Corps, the U.S. 17th Infantry Regiment, and other elements at the Yalu-might be cut off by the weight of the Chinese offensive, the X Corps was forced to withdraw these elements. Troops at the reservoir were also ordered to fall back. MacArthur then ordered Almond to concentrate the X Corps in the Hamhung-Hungnam area; and early in December directed the Corps to withdraw to South Korea by a waterborne evacuation.
Most of the Corps reached the port of Hungnam without serious incident. However, some 14,000 men of the 1st Marine and 7th Infantry Divisions were trapped in the Hagaru-Kot'o area and were forced to fight their way to the coast along a narrow escape route. As the main column progressed along the road, a provisional battalion of marines and soldiers, aided by close and efficient air support, cleared the Chinese Communist forces from the high ground which dominated the road. Almond sent Task Force Dog, a reinforced battalion of the 3d Division, forward to Chinhung to relieve the Marine battalion there and to assist the withdrawal by providing support and rear guard action. Air Force, Navy, and Marine cargo planes parachuted daily airdrops of ammunition, food, and medicines to the column, and evacuated battle casualties. Fighter elements bombed and strafed the enemy-held mountainsides and Communist troop concentrations. On 9 December 1950 the two forces met in the mountains a few miles south of Kot'o and both moved toward Hamhung to be evacuated.
The water movement of the X Corps from North Korea required 173 vessels. About 350,000 measurement tons of cargo, including 17,500 vehicles, were salvaged; some 105,000 troops and more than 98,000 civilians were evacuated from Hungnam, Songjin, and Wonsan. Evacuation began on 11 December and was completed on 24 December, despite constant enemy fire and observation.
The Hungnam evacuation left North Korea once again controlled by Communist forces. Before the enemy renewed his attacks, General Walker was killed in an auto accident north of Seoul (23 December 1950). On 26 December Lt. Gen. Matthew B. Ridgway succeeded him in command of the Eighth Army in Korea.
On 30 December MacArthur warned the U.S. Joint Chiefs of Staff that the Chinese Communist forces could drive the U.N. forces out of Korea if they so desired. The United States, although anxious to avoid a full-scale war in Korea, was also determined to resist the Chinese-North Korean aggressors. Therefore the Joint Chiefs ordered MacArthur to defend his positions; to retire, if forced to, through a series of defensive positions as far back as the former Pusan Perimeter Line; to inflict as much damage as possible on the enemy; and to maintain his units intact. If necessary to avoid severe losses, he was authorized to withdraw to Japan.
Within this framework of operations, MacArthur invested General Ridgway with complete authority to plan and execute operations in Korea, and ceased the close supervision which he had formerly exercised over the Eighth Army and the X Corps. The latter, which had heretofore been a separate command, was assigned to the Eighth Army, thus placing all U.N. ground forces under that army's control. By this time fifteen nations of the U.N. had troops in Korea-the United States, Great Britain, Australia, Canada, New Zealand, India, South Africa, France, Greece, the Netherlands, the Philippines, Thailand, Turkey, Belgium, and Sweden. As 1951 began, U.N. ground forces numbered about 495,000, of which 270,000 were ROK troops. The U.N. Command estimated that the enemy had about 486,000 men, 21 Chinese and 12 North Korean divisions, committed to the Korean front, and more than a million enemy troops stationed in reserve near the Yalu.
In late December, Ridgway, in establishing the defensive line along the 38th parallel, concentrated the bulk of the Eighth Army in the central and western sectors because of the obvious enemy concentration above Seoul. The west flank was held by the I Corps; the central sector by the IX Corps; and the ROK I, II, and III Corps held the eastern mountainous sector. The X Corps was reorganizing near Pusan. The 1st Marine Division, until recently a part of the X Corps, was held in Eighth Army reserve.
At daybreak on 1 January 1951, after a night of mortar and artillery bombardment, the enemy launched an attack all along the U.N. line. The main effort was directed against the U.S. I and IX Corps in the west and central sectors. A force of seven Chinese armies and two North Korean corps pushed deeply into the U.N. line toward Seoul in the west and Wonju in the center.
As the offensive gained momentum, Ridgway ordered the U.N. forces to fall back to a line which ran along the south bank of the frozen Han River to Yangp'yang, through Hongch'on and Chunmunjin to the Sea of Japan. A delaying force remained around Seoul to deny the enemy use of the Han River bridges. When the attacking forces, following up their initial success, crossed the Han to the east and west of Seoul, it became clear that the Seoul bridgehead could not be held any longer. Ridgway, following a policy of rolling with the punch rather then risking destruction by defending in place, decided to withdraw south to a line in the vicinity of the 37th parallel on 3 January. This line ran from P'yongt'aek, east through Ansong, northeast to Wonju, and in an irregular trace to the east coast town of Samch'ok. When Seoul fell on 4 January, the port of Inch'on was also evacuated.
After the fall of Seoul, Chinese attacks tapered off in the west. Many enemy units were shifted eastward so as to be in position to attack southwestward behind the U.S. I and IX Corps, and capture Wonju and the railroad and highway between Hongch'on and Pusan, the main U.N. north-south supply route. Wonju was abandoned by U.N. forces on 7 January. By 10 January large numbers of the enemy had phased through the gap and into the defensive zone of the ROK III Corps. To meet this threat Ridgway ordered the 1st Marine Division to prevent the enemy penetration from north of the Andong-Yongdok road on the east, and to protect the supply routes of the ROK units.
In the western sector, which was comparatively quiet, Ridgway planned Operation WOLFHOUND, a reconnaissance in force in the I Corps sector, to reestablish contact and secure more exact information about the enemy. On 15 January the task force-the 27th Infantry Regiment, reinforced-advanced northward along the Seoul highway toward Osan. On the 16th it reached Suwon with practically no opposition. Satisfied by the reconnaissance, the U.N. Command ordered the task force to withdraw south.
By the third week in January the situation in the central and eastern sectors had eased, and pressure on our troops was gradually decreasing. However, although quiet prevailed on the front, air reconnaissance revealed that the enemy was accumulating reserves of supplies and bringing up thousands of replacements.
