Land the Fire Brigade
On 2 July 1950, the Chief of Naval Operations ordered a reinforced regiment with supporting air assets be assembled for immediate transportation to Korea. On 7 July 1950, the First Provisional Marine Brigade — stripped out from an already under-strength First Marine Division — was activated and placed under the command of Brigadier General Edward A. Craig. The major elements of the brigade included the 5th Marine Regiment, Marine Aircraft Group 33, and supporting arms. The brigade’s strength was 6,534, and within ten days after receiving the warning order, on 12 July 1950, the first elements set sail for the Far East. On 14 July, all the remaining units of the brigade departed from the West Coast, and within twenty days, two Marine air squadrons had commenced combat operations from escort carriers
The 8th Army became operational in Korea by 13 July 1950. As the North Koreans continued to push its way down the peninsula against the outnumbered American and scattered Republic of Korea defenders, the 24th Infantry Division struggled tenaciously to slow the invaders but by 21 July, Taejon was surrendered to the North Koreans after street-by-street, house-by-house combat. The division's forces were spread as far south as Taegu and its commander, Major General William F. Dean, became missing in action during the battle for Taejon. Although defeated, the 8th Army gained time to stiffen its resistance with the 25th Infantry and 1st Cavalry Divisions, which arrived to man critical sectors of an ever- shrinking front.
Eventually, the 8th Army, along with remaining ROK forces assigned to it, was moved into the southeast corner of Korea which became known as the Pusan Perimeter. General Walker declared that Pusan would be no Dunkirk: "The Eighth Army would stay in Korea until the invader was expelled from the territory of the Republic of Korea." Fighting off continued attacks all across the perimeter, the Eighth Army was eventually able to hold its positions and grow in strength, both in terms of personnel, equipment, and experienced small unit leaders.
With the 8th United States Army being pressed back into what became known as the Pusan Perimeter, entirely the result of personnel and equipment cuts that took all military forces to a “bare bones” level, General MacArthur had important plans for the 1st Marine Provisional Brigade. His original plan was to have the Brigade (both ground and air) disembark at Kobe, Japan and engage in several weeks of training and rehearsal before being employed in combat. But the situation in Korea became critical when the 8th Army was unable to hold the line at the Kum River and the city of Chinju was lost to the North Korean forces. Now, the left flank of UN forces was turned and Pusan itself was threatened. By 1 August 1950, five of the 8th Army’s seven infantry divisions were nearing exhaustion and panic was setting in among the tightly packed Pusan region. One set of rumors were contradicted by new, equally false reports — but all were alarming to civilians and defenders alike.
The Pusan perimeter consisted of 125 miles of mountains, plains, and rivers. Attacking forces always retain the initiative over defenders, so in many instances the question wasn’t whether UN forces could hold the line, but rather where the next breakthrough would occur. Upon arrival in Korea ahead of the Brigade, Brigadier General Craig familiarized himself with the military situation around the Pusan Perimeter, and it wasn’t a pleasant picture. North Korean forces dominated all areas north of the Naktong River, held the city of Yongdak on the east coast, and they were threatening the city of Masan, which was only 35 miles from Pusan. He knew that unless the North Koreans were stopped, no matter what General Walker had said, the Americans would experience their own “Dunkirk.”
Of the 8 infantry divisions serving under the 8th Army, four were American and four South Korean. The American divisions had been hastily formed from occupation forces serving in Japan, and even more hastily committed to combat; they were lacking essential equipment and training, and they were staffed at only 40% of normal war time strength. In General Craig’s opinion, these divisions were psychologically and physically unprepared for battle. The combination of defeat, retreat, lack of experience, and poor discipline were contributing factors in this most critical situation. In addition, the number of soldiers who were missing in action produced low morale and a feeling of hopelessness. ROK forces, who were primarily trained for constabulary duties, were utterly outclassed by the North Koreans.
Facing American and ROK forces were eleven infantry divisions of the North Korean People's Army (NKPA). They were well trained, well equipped, and led by experienced officers and NCOs; many were seasoned veterans who gained experience while fighting with the Chinese Communists against Chinese Nationalists. There was no doubt in the minds of North Korean senior officers that they would be in Pusan before the 15th of August.
On 2 August 1950, elements of the brigade came ashore at Pusan, and General Craig met with his senior officers. He told them:
“The situation is serious, gentlemen. With forces available, it is obvious that the perimeter cannot be held in strength. Eighth Army has adopted a plan of holding thinly and ounter-attacking enemy penetrations to keep them off balance to prevent them from launching a coordinated effort.”
“At the moment, General Walker is undecided in what area we’re going to be used. We may go north of Taegu and operate on the left flank of the 1st Cavalry Division, or we may go west to check an enemy advance along the Masan Road. It all depends upon where the greatest threat develops.”
“We’re going into battle against a vicious, well-trained enemy in what will be an extended land campaign. Unfortunately, we will have to forget the plan of an amphibious landing. We will miss the vehicles we had to leave behind in San Diego. Much of our moving will be done on foot. We will leave all nonessential supplies and equipment in storage on the docks right here. We’ll carry with us two days of rations, and two units of fire.” (See note, below)
“The Pusan Perimeter is like a weakened dike and we’ll be used to plug the holes in it as they open. We’re a brigade — a fire brigade. It will be costly fighting against a numerically superior enemy. Marines have never yet lost a battle; this Brigade will not be the first to establish such a precedent. Unloading will begin at once.”
At dawn the next day, the 5th Marine Regiment moved west to an assembly area at Changwon. Initially, the Marines were ordered to the west of Pusan to protect the Army’s southern flank. The Marines promptly closed with the enemy and defeated them, but around the same time, elements of the NKPA were pressing towards Masan and the brigade was assigned Sachon as its objective as part of the U.S. Army 25th Division's counterattack.
On 7 August 1950, a month after its activation and the anniversary of the Marine landing on Guadalcanal, the Brigade launched an attack toward Chinju, but as the 5th Marines were about to enter Sachon on 13 August, they received new orders to disengage the enemy and move towards the so-called "Naktong Bulge" — a salient created by the 4th NKPA Division crossing the river near Obong-ni, some 75 miles north of Sachon. Within the Perimeter, the Marine Brigade was to move over 350 miles within a 30 day period to meet and defeat the North Koreans at critical points. General Craig was correct: the Marines became the “fire brigade.”
Before 7 August, Marines from MAG-33 were already engaged in sorties in support of the 8th Army. Operating off the USS Badoeng Strait and USS Sicily, air squadrons consisted of VMF 323, VMF 214, and VMF(N) 513, flew close air support to infantry units, while VMO 6 was attached to the Brigade as observation aircraft. The honor of drawing the first enemy blood went to the aviation Marines on 5 August when corsairs from the Sicily provided the enemy with on-the-job training about what to expect from the World War II vintage gull-winged aircraft. While looking for targets of opportunity, a flight of corsairs led by Major Ken Reusser spotted trucks around a building and launched an attack, but the amount of anti-aircraft weapons used against the attacking Marines gave them cause to wonder what was inside the building. Another pass revealed a tank assembly plant, and so after destroying most of the trucks and around 30 enemy soldiers, Reusser returned his flight to the ship for refueling, rearmed the aircraft with napalm and rockets and planned a second mission. When the Marines had completed the second sortie of the day, there was no building, no tanks, and no evidence of surviving enemy soldiers.
In spite of President Truman's call for UN assistance, most UN member nations were facing the same kinds of post-World War II problems as the United States; only Great Britain’s commonwealth nations were able to field combat forces to assist with the Korean intervention — other nations would join the conflict later on. These circumstances largely made the beginning of the Korean War an American/South Korean show; from the beginning, the “issue was in doubt.”
