World War II · The Pacific · 7 August 1942 – 9 February 1943
Guadalcanal
An unfinished airstrip on a British island in the Solomons became the place where the United States went over to the offensive in the Pacific. For six months Marines, soldiers, sailors, airmen and Solomon Islanders fought the Japanese Army and Navy for it, on land, at sea, in the air and against the jungle itself.
The collection
Six months for one airfield
On the morning of 7 August 1942 the 1st Marine Division landed almost unopposed on the north coast of Guadalcanal and fought hard for the small islands of Tulagi, Gavutu and Tanambogo across the water. The next day the Marines took the airfield the Japanese had nearly finished at Lunga Point. Within two days a Japanese cruiser force had sunk four Allied heavy cruisers off Savo Island, the transports had left with half their cargo still aboard, and the Marines were on their own.
What followed was a campaign of attrition unlike anything else in the war. By day the aircraft of the “Cactus Air Force” at Henderson Field owned the air over the island; by night Japanese destroyers ran down “the Slot” to land troops and shell the perimeter. Japanese attacks at the Tenaru, on Edson’s Ridge and against the southern line in October broke against the Marines and the Army’s 164th Infantry. Seven major naval battles, two of them fought by battleships at night, filled the strait off Lunga with so many wrecks that sailors called it Iron Bottom Sound. Malaria put more men in hospital than bullets did, and the Japanese Army on the island starved; its soldiers called Guadalcanal Gatō, “the island of starvation.”
In February 1943 Japanese destroyers secretly took off about 10,600 survivors. The cost had been roughly 7,100 American and Allied dead and, by different counts, between about 19,000 and 31,000 Japanese. This collection tells the whole campaign in nine illustrated chapters drawn from the official histories, with ten Special Units pages, a 100-question FAQ and the interactive features below: an atlas on the real coastline, a sonar chart of the wrecks in Iron Bottom Sound, a day-and-night clock of the Slot, the night the battleships shelled Henderson Field, star shells you fire over night photographs, and then-and-now comparisons.
Figures are given with their sources in the chapters; where counts differ, both are shown. Times are local Guadalcanal time (GMT+11).

The atlas
From Rabaul to Lunga Point
Guadalcanal lies at the southern end of the double chain of the Solomon Islands, about 565 nautical miles from the Japanese base at Rabaul. The channel between the two chains, the New Georgia Sound, was “the Slot” to the Americans. Tap any point on the maps for what happened there, or step through the phases of the campaign.

Each chapter is a long, illustrated account with maps, charts, a minute-by-minute scrubber, a decision you can make yourself, profiles of the people involved and a full list of sources.










Iron Bottom Sound
The wrecks beneath the Sound
Between August 1942 and February 1943 dozens of warships and transports went down in the strait between Guadalcanal, Savo and the Florida Islands. Robert Ballard’s expedition surveyed many of the wrecks in 1992, and later surveys, including the research vessel Petrel in 2019 and Nautilus in 2025, found and identified more. The sonar below plots every loss our sources place in or near the Sound. Positions are approximate unless a card says otherwise, and the ships are war graves.

Casualty figures are as given by the Naval History and Heritage Command H-Grams where available, otherwise by Wikipedia battle articles (used as pointers to Frank, Morison and others); where sources differ, the range is shown. Japanese naval casualty figures are less complete than American ones.
Day and night
The day belonged to Cactus. The night belonged to the Tokyo Express.
From August to November neither side could hold the waters around Guadalcanal around the clock. American dive bombers from Henderson Field could strike ships within range in daylight, so Japanese destroyers waited out of range by day, ran down the Slot at high speed after dark, landed men and supplies near Tassafaronga and Cape Esperance around midnight, and tried to be far up the Slot again by dawn. Drag the clock to see how the pattern worked.
At night the Japanese also lit their targets. At Savo Island cruiser floatplanes dropped parachute flares behind the Allied ships, silhouetting them for the Japanese gunners and torpedomen. Fire your own star shells over the photograph taken from the cruiser Chōkai that night.
“The Night”
When the battleships came
At 0133 on 14 October 1942 a Japanese floatplane dropped flares over Henderson Field, and minutes later the battleships Kongō and Haruna opened fire from Iron Bottom Sound. In about eighty minutes they fired some 918 fourteen-inch shells into the airfield, by the count most often used (others give 973 or “almost 1,000”). Forty-one Americans were killed, most of the aviation fuel burned, and only a fraction of the field’s aircraft could fly the next morning. Read the full story in Chapter 6.

Special Units
The units and people of Guadalcanal
Ten pages follow units and people through the campaign, from Edson’s and Carlson’s Raiders to the coastwatchers, Sir Jacob Vouza, Douglas Munro, the Army’s 164th Infantry, USS Juneau and the five Sullivan brothers, and the Battleship North Carolina, now a memorial at Wilmington. A record page explains the Japanese destroyer runs of the Tokyo Express. The badges are original illustrations, not official emblems. More units from every campaign are on the Special Units hub.

Questions
Guadalcanal in brief
Why was Guadalcanal important?
The Japanese were building an airfield at Lunga Point that would have let land-based bombers threaten the sea route between the United States and Australia. Taking it gave the Allies an airbase of their own and drew Japan into a six-month battle of attrition it could not afford. See Chapter 1.
Why is it called Iron Bottom Sound?
American sailors gave the name to the strait between Guadalcanal, Savo and the Florida Islands because so many ships of both sides were sunk there in 1942–43. Explore the wrecks in the sonar chart above.
What was the Cactus Air Force?
“Cactus” was the Allied code name for Guadalcanal. The Marine, Navy and Army aircraft flying from Henderson Field were called the Cactus Air Force. Read the unit page and Chapter 3.
How many people died on Guadalcanal?
The National WWII Museum gives about 7,100 Allied and about 31,000 Japanese dead; other counts of Japanese deaths run from about 19,200 upward. Many more Japanese died of disease and starvation than in combat. See Chapter 9.
Can you visit Guadalcanal today?
Yes. Honiara, the capital of Solomon Islands, grew up around the wartime base, and Henderson Field is now Honiara International Airport. Visitors see the Guadalcanal American Memorial on Skyline Ridge, Bloody Ridge, the Vilu War Museum and the wrecks at Bonegi; unexploded ordnance is still a danger away from cleared sites.
From Lake Norman to the Solomons
The battleship USS North Carolina (BB-55) defended the carrier Enterprise at the Battle of the Eastern Solomons on 24 August 1942 and was torpedoed by the Japanese submarine I-19 on 15 September, in the same attack that sank the carrier Wasp. Saved by a statewide campaign of North Carolinians, she has been a memorial at Wilmington since 1961. The 2nd Marine Division, which fought on Guadalcanal from November 1942, is based today at Camp Lejeune. Read USS North Carolina at Guadalcanal and visit the Battleship North Carolina.
