Guadalcanal Campaign
Battle of Guadalcanal
****************************
The island of Guadalcanal was the first land offensive (Pacific theater) of World War II. If we had lost the first battle, we could have lost the war. We had great Marine heroes like Don Jardine - Guadal123@aol.com and Herman Shirley - h_shirley@sbcglobal.net on the attack, armed with the old bolt action O3 World War 1 rifles, as members of (B-1-1) B Company, 1st Battalion, 1st Marine Regiment, 1st Marine Division. Don now lives in San Francisco, and Herman lives in Huntsville, Texas. Don, Herman, and many other veterans of Guadalcanal continued fighting the Japanese on June 15, 1944 at Cape Gloucester, and again on Sept. 15, 1944 on the island of Peleliu. You might want to send them an email with a "thank you" message. Without very brave men like them, we could have been speaking Japanese today.
*** The Guadalcanal Campaign, also known as the Battle of Guadalcanal, was fought between August 7, 1942 and February 9, 1943 on and around the island of Guadalcanal in the Pacific theater of World War II. Fiercely contested on the ground, at sea, and in the air, the campaign was the first major offensive launched by Allied forces against the Empire of Japan.
***
On August 7, 1942, Allied forces, predominantly American, initiated landings on the islands of Guadalcanal, Tulagi, and Florida (Nggela Sule) in the southern Solomon Islands with the objective of denying their use by the Japanese as bases to threaten supply routes between the U.S., Australia, and New Zealand. The Allies also intended to use Guadalcanal and Tulagi as bases to support a campaign to eventually capture or neutralize the major Japanese base at Rabaul on New Britain. The Allies overwhelmed the outnumbered Japanese defenders, who had occupied the islands since May 1942, and captured Tulagi and Florida, as well as an airfield (later named Henderson Field) that was under construction on Guadalcanal.
***
Surprised by the Allied offensive, the Japanese made several attempts between August and November 1942 to retake Henderson Field. Three major land battles, five large naval battles, and continual, almost daily, aerial battles, culminated in the decisive Naval Battle of Guadalcanal in early November 1942, in which the last Japanese attempt to land enough troops to capture Henderson Field was defeated. In December 1942, the Japanese abandoned further efforts to retake Guadalcanal and evacuated their remaining forces by February 7, 1943.
***
The Guadalcanal campaign marked the first significant strategic combined arms victory by Allied forces over the Japanese in the Pacific theater. For this reason, the Guadalcanal campaign is often referred to as a "turning point" in the war. The campaign marked the beginning of the transition by the Allies from defensive operations to the strategic offensive, while Japan was thereafter forced to cease strategic offensive operations and instead concentrate on strategic defense.

Background
On December 7, 1941, Japanese forces attacked the United States Pacific Fleet at Pearl Harbor, Hawaii. The attack crippled much of the U.S. battleship fleet and precipitated an open and formal state of war between the two nations. The initial goals of Japanese leaders were to neutralize the U.S. Navy, seize possessions rich in natural resources, and establish strategic military bases to defend Japan's empire in the Pacific and Asia. To further those goals, Japanese forces captured the Philippines, Thailand, Malaya, Singapore, the Dutch East Indies, Wake Island, Gilbert Islands, New Britain, and Guam. Joining the U.S. in the war against Japan were the rest of the Allied powers, several of whom, including Great Britain, Australia, and the Netherlands, had also been attacked by Japan.
***
Two attempts by the Japanese to maintain the strategic initiative and extend their defensive perimeter in the south and central Pacific had been thwarted at the naval battles of Coral Sea and Midway respectively. Midway was not only the Allies' first decisive victory against the previously undefeated Japanese, it significantly reduced the offensive capability of Japan's carrier forces. Up to this point, the Allies had been on the defensive in the Pacific, but these strategic victories provided them an opportunity to take the initiative and launch two offensives in the Pacific.
***
The Allies chose the Solomon Islands (a protectorate of Great Britain), specifically the southern Solomon Islands of Guadalcanal, Tulagi, and Florida as the first target. The Japanese Navy (IJN) had occupied Tulagi in May 1942 and had constructed a seaplane base near there. Allied concern grew when, in early July 1942, the IJN began constructing a large airfield at Lunga Point on nearby Guadalcanal. By August 1942, the Japanese had about 900 naval troops on Tulagi and nearby islands, and 2,800 personnel (2,200 being Korean and Japanese construction specialists) on Guadalcanal. These bases, when completed, would protect Japan's major base at Rabaul, threaten Allied supply and communication lines, and establish a staging area for a planned offensive against Fiji, New Caledonia, and Samoa (Operation FS). The Japanese planned to deploy 45 fighters and 60 bombers to Guadalcanal once the airfield was complete. These aircraft could provide air cover for Japanese naval forces advancing further into the South Pacific.
***
The Allied plan to invade the southern Solomons was conceived by U.S. Admiral Ernest King, Commander in Chief, United States Fleet. He proposed the offensive to deny the use of the islands by the Japanese as bases to threaten the supply routes between the United States and Australia, and to use them as starting points. With Roosevelt's tacit consent, King also advocated the invasion of Guadalcanal. When U.S. Army General George C. Marshall resisted this line of action as well as who would command the operation, King stated that the Navy and Marines would carry out the operation by themselves, and instructed Admiral Chester Nimitz to proceed with the preliminary planning. King eventually won the argument, and the invasion went ahead with the backing of the Joint Chiefs.
***
Guadalcanal would be carried out in conjunction with an Allied offensive in New Guinea under Douglas MacArthur, to capture the Admiralty Islands and the Bismarck Archipelago, including the major Japanese base at Rabaul. The eventual goal was the American reconquest of the Philippines. The U.S. Joint Chiefs of Staff created the South Pacific theater, with Vice Admiral Robert L. Ghormley taking command on June 19, 1942, to direct the offensive in the Solomons. Admiral Chester Nimitz, based at Pearl Harbor, was designated as overall Allied commander in chief for Pacific forces.
***
In preparation for the future offensive in the Pacific in May 1942, U.S. Marine Major General Alexander Vandegrift was ordered to move his 1st Marine Division from the United States to New Zealand. Other Allied land, naval, and air force units were sent to establish bases in Fiji, Samoa, New Hebrides, and New Caledonia. Espiritu Santo, New Hebrides, was selected as the headquarters and main base for the offensive, codenamed Operation Watchtower, with the commencement date set for August 7, 1942. At first, the Allied offensive was planned just for Tulagi and the Santa Cruz Islands, omitting Guadalcanal. However, after Allied reconnaissance discovered the Japanese airfield construction efforts on Guadalcanal, its capture was added to the plan, and the Santa Cruz operation was (eventually) dropped. The Japanese were aware, via signals intelligence, of the large-scale movement of Allied assets in the South Pacific area, but concluded that the Allies were reinforcing Australia and perhaps Port Moresby in New Guinea.
***
The Watchtower force, numbering 75 warships and transports (including vessels from both the U.S. and Australia), assembled near Fiji on July 26, 1942, and engaged in one rehearsal landing prior to leaving for Guadalcanal on July 31. The on-scene commander of the Allied expeditionary force was U.S. Vice Admiral Frank Fletcher (flag in aircraft carrier USS Saratoga). Commanding the amphibious forces was U.S. Rear Admiral Richmond K. Turner. Vandegrift led the 16,000 Allied (primarily U.S. Marine) infantry earmarked for the landings.
***
Landings
Bad weather allowed the Allied expeditionary force to arrive in the vicinity of Guadalcanal unseen by the Japanese on the morning of August 7. The landing force split into two groups, with one group assaulting Guadalcanal, and the other Tulagi, Florida, and nearby islands. Allied warships bombarded the invasion beaches while U.S. carrier aircraft bombed Japanese positions on the target islands and destroyed 15 Japanese seaplanes at their base near Tulagi.
***
Tulagi and two nearby small islands, Gavutu and Tanambogo, were assaulted by 3,000 U.S. Marines. The 886 IJN personnel manning the naval and seaplane bases on the three islands fiercely resisted the Marine attacks. With some difficulty, the Marines secured all three islands; Tulagi on August 8, and Gavutu and Tanambogo by August 9. The Japanese defenders were killed almost to the last man, while the Marines suffered 122 killed.
***
In contrast to Tulagi, Gavutu, and Tanambogo, the landings on Guadalcanal encountered much less resistance. At 09:10 on August 7, Vandegrift and 11,000 U.S. Marines came ashore on Guadalcanal between Koli Point and Lunga Point. Advancing towards Lunga Point, they encountered no resistance except for "tangled" rain forest, and they halted for the night about 1,000 yards (910 m) from the Lunga Point airfield. The next day, again against little resistance, the Marines advanced all the way to the Lunga River and secured the airfield by 16:00 on August 8. The Japanese naval construction units and combat troops, under the command of Captain Kanae Monzen, panicked by the warship bombardment and aerial bombing, had abandoned the airfield area and fled about 3 miles (4.8 km) west to the Matanikau River and Point Cruz area, leaving behind food, supplies, intact construction equipment and vehicles, and 13 dead.
***
During the landing operations on August 7 and August 8, Japanese naval aircraft based at Rabaul, under the command of Sadayoshi Yamada, attacked the Allied amphibious forces several times, setting afire the U.S. transport George F. Elliot (which sank two days later) and heavily damaging the destroyer USS Jarvis. In the air attacks over the two days, the Japanese lost 36 aircraft, while the U.S. lost 19, both in combat and to accident, including 14 carrier fighters.
***
After these clashes, Fletcher was concerned about the losses to his carrier fighter aircraft strength, anxious about the threat to his carriers from further Japanese air attacks, and worried about his ship's fuel levels. Fletcher withdrew from the Solomon Islands area with his carrier task forces the evening of August 8. As a result of the loss of carrier-based air cover, Turner decided to withdraw his ships from Guadalcanal, even though less than half of the supplies and heavy equipment needed by the troops ashore had been unloaded. Turner planned, however, to unload as many supplies as possible on Guadalcanal and Tulagi throughout the night of August 8 and then depart with his ships early on August 9.
***
That night, as the transports unloaded, two groups of screening Allied warships under the command of British Rear Admiral Victor Crutchley were surprised and defeated by a Japanese force of seven cruisers and one destroyer from the 8th Fleet, based at Rabaul and Kavieng and commanded by Japanese Vice Admiral Gunichi Mikawa. One Australian and three American cruisers were sunk, and one American cruiser and two destroyers were damaged in the Battle of Savo Island. The Japanese suffered moderate damage to one cruiser. Mikawa, who was unaware Fletcher had withdrawn with the U.S. carriers, immediately retired to Rabaul without attempting to attack the now unprotected transports. Mikawa was concerned about daylight U.S. carrier air attacks if he remained in the area. Turner withdrew all remaining Allied naval forces by the evening of August 9, leaving the Marines ashore without much of the heavy equipment, provisions, and troops still aboard the transports. However, Mikawa's decision not to attack the Allied transport ships when he had the opportunity would prove to be a crucial strategic mistake.

Initial operations
The 11,000 Marines on Guadalcanal initially concentrated on forming a loose defensive perimeter around Lunga Point and the airfield, moving the landed supplies within the perimeter, and finishing the airfield. In four days of intense effort, the supplies were moved from the landing beach into dispersed dumps within the perimeter. Work began on the airfield immediately, mainly using captured Japanese equipment. On August 12, the airfield was named Henderson Field after a Marine aviator, Lofton R. Henderson who was killed during the Battle of Midway. By August 18, the airfield was ready for operation. Five days worth of food had been landed from the transports, which, along with captured Japanese provisions, gave the Marines a total of 14 days worth of food. To conserve supplies, the troops were limited to two meals per day. Allied troops encountered a "severe strain" of dysentery soon after the landings, with one in five Marines afflicted by mid-August. Although some of the Korean construction workers surrendered to the Marines, most of the remaining Japanese and Korean personnel gathered just west of the Lunga perimeter on the west bank of the Matanikau River and subsisted mainly on coconuts. A Japanese naval outpost was also located at Taivu Point, about 35 kilometres (22 mi) east of the Lunga perimeter. On August 8, a Japanese destroyer from Rabaul delivered 113 naval reinforcement troops to the Matanikau position.
***
On the evening of August 12, a 25-man U.S. Marine patrol, led by Lieutenant Colonel Frank Goettge and primarily consisting of intelligence personnel, landed by boat west of the Lunga perimeter, between Point Cruz and the Matanikau River, on a reconnaissance mission with a secondary objective of contacting a group of Japanese troops that U.S. forces believed might be willing to surrender. Soon after the patrol landed, a nearby platoon of Japanese naval troops attacked and almost completely wiped out the Marine patrol.
***
In response, on August 19, Vandegrift sent three companies of the U.S. 5th Marine Regiment to attack the Japanese troop concentration west of the Matanikau. One company attacked across the sandbar at the mouth of the Matanikau river while another crossed the river 1,000 metres (1,100 yd) inland and attacked the Japanese forces located in Matanikau village. The third landed by boat further west and attacked Kokumbuna village. After briefly occupying the two villages, the three Marine companies returned to the Lunga perimeter, having killed about 65 Japanese soldiers while losing four. This action, sometimes referred to as the "First Battle of the Matanikau", was the first of several major actions around the Matanikau River during the campaign.
***
On August 20, the escort carrier USS Long Island (CVE-1) delivered two squadrons of Marine aircraft to Henderson Field, one of 19 Grumman F4F Wildcats, the other 12 SBD Dauntlesses. The aircraft at Henderson became known as the "Cactus Air Force" (CAF) after the Allied codename for Guadalcanal. The Marine fighters went into action the next day, attacking one of the almost-daily Japanese bomber air raids. On August 22, five U.S. Army P-400 Airacobras and their pilots arrived at Henderson Field.
***
Approximately 1,769 U.S. Marines perished on Guadalcanal, and about 420 airmen; but close to 5,000 U.S. sailors died fighting from 27 US Navy warships that were sunk, in histories most savage and furious sea battles, surrounding the Guadalcanal islands.
