Let us go forward to certain victory in the traditional night attack of the Imperial Navy.
May each one of us calmly do his utmost.

This sketch of the events of the Guadalcanal Campaign is based on several sources, many listed in the bibliography. The original basis of the chronological table, however, was the Simulations Publications, Inc. (SPI) wargame "Bloody Ridge, Turning Point on Guadalcanal, September 1942" (in "Island War, Four Pacific Battles," Simulations Publications, Inc., 1975). The 70's were the golden age of board wargaming, and Simulations Publications was the leader. Unfortunately, although computers promised to pick up in innovation and realism where the board games left off, I'm not sure that it all has turned out to be quite the same thing. A real computer military game would require small individual terminals, for input, but then a large, flat, maplike display to show (or sometimes conceal) the information available to all players. The technology now approaches this possibility. Meanwhile, Simulations Publications is long gone. Its flagship magazine, however, Strategy & Tactics, does continue, published by Decision Games.
"Bloody Ridge" covered the Battles of Bloody Ridge in September and for Henderson Field in October, 1942. It skipped over the Battle of the Tenaru River in August and did not provide a scenario for the November offensive that the Japanese would have mounted if so many of their forces and supplies had not been sunk at sea after the Naval Battle of Guadalcanal (12-14 November 1942). Indeed, the first elements of the 38th Division, intended for that offensive, are already arriving at the end of the game's alotted moves.
"Guadalcanal" in Japanese would ordinarily be written Gadarukanaru in the katakana syllabary. At the time, however, the bitter jest among the Japanese, most of whose soldiers on Guadalcanal ended up rendered ineffective by starvation, was that the first syllable should be written with , which means "hungry" or "starve." This is also the character we find in , which means "hungry ghosts," those who in Buddhism are reborn in the "realm" where they wander the earth eating waste. The fear of many Japanese, indeed, is that Japanese soldiers who died missing in action in many places in World War II, and whose bones may lie without proper burial or rites, did end up as hungry ghosts in such places.
A Marine correspondent recently pointed out that Marine units were not listed here. They were not, since I was not providing an order of battle. Now, however, I regard this as a deficiency and have begun to make up for it. Above left is the organizational chart for the First Marine Division, whose 1st, 5th, and 11th Marines were the first to land on Guadalcanal. The 7th Marines arrived in September. This is based on W. Victor Madej, U.S. Army and Marine Corps Order of Battle, Pacific Theater of Operations, 1941-1945, Volume I [Game Publishing Company, Allentown, Pennsylvania, 1984, pp.137-138]. The detail of supporting units is as Madej gives them. An attempt has been made to match special units with the symbols used in "Bloody Ridge." Note that Marine regiments are simply identified as "Marines," not as "Infantry" or "Artillery" as in the U.S. Army. Below right is the organizational chart for the Americal Division, whose 164th Infantry Regiment arrived on Guadalcanal in October. This is based on W. Victor Madej, U.S. Army Order of Battle, Pacific Theater of Operations, 1941-1945 [Game Publishing Company, Allentown, Pennsylvania, 1984, p.22]. Details of the symbols are explained at "Military Rank". In the organizational diagrams, U.S. Marines are red, U.S. Army green, and Japanese Army orange. Orange was pre-War code color for Japan in U.S. planning. Thus, "Case Orange" was the naval plan for war with Japan, an obsolete and useless plan, as it happened, since it assumed the tactical supremacy of battleships in naval warfare.
The great historical interest of the Guadalcanal campaign (and, to a lesser extent, that of the subsequent actions on the rest of the Solomons) is due to two factors: (1) the combination of air, land, and sea operations, (2) the relative equality of the forces, and (3) the unusally large number (for World War I or II) of surface-to-surface naval battles. Thus, although many think of Guadalcanal in terms of the land battles, there were more naval battles fought off the island in six months than the British Royal Navy fought in all of World War I. There is nothing else quite like them in even the rest of World War II. The name given to the strait between Guadalcanal and Savo Island, "Iron Bottom Sound," was no less than descriptive of the carpetting of ships (now observed by modern divers and submersibles) that the bottom received. A serious student of naval history cannot avoid the naval battles in the Solomons.
The intensity of the battles at sea and on land was due in great part to the rough equality of the forces involved. The industrial strength of the United States had not yet flooded the Pacific with new construction. Because of previous losses, sometimes the U.S. Navy only had one operational carrier (the Enterprise) in the area. The Japanese Navy had been similarly reduced by losses, but there also would never in the future be much in the way of new construction to replace the losses. The few new ships and planes upon which the Japanese later placed all their hopes were mostly destroyed in the Battle of the Philippine Sea (19-20 June 1944). The Japanese Navy was then destroyed as an organized force at the Battle (actually battles, five of them) for Leyte Gulf (23-26 October 1944).
On this map, locations relevant to the Solomons campaign are in red, the Papua-New Guinea campaign in green, and naval battles, including other battles in the area, in blue. New Guinea was the scene of an ambitious contemporary Japanese offensive and then Allied counteroffensive. The five battles in the waters off Guadalcanal, which include the two nights of the Naval Battle of Guadalcanal, are listed in sequence to the left of the island. The two carrier battles were fought off the map to the right. Island names are all upper case. Base names are in upper and lower case. The naval battles extend beyond the Guadalcanal Campaign through the rest of the campaign in the Solomons. Thus, the last naval battle on the map, in fact the last battle altogether, was Cape St. George on 25 November 1943. That ended Japanese efforts to resupply or evacuate the Japanese forces that had become trapped on Bougainville. Meanwhile, the main Japanese base for the whole area, at Rabaul, had itself become trapped and isolated. A notable incident in the later campaign was the ramming and sinking of torpedo boat PT-109 by the destroyer Amagiri, on 2 August 1943 off New Georgia. Since PT-109 was commanded by John F. Kennedy, who was credited with heroism, this became part of the story of his Presidency.
In November 1942, when the Japanese Army gave up hope of retaking Guadalcanal, and the Japanese Navy ceased trying to send reinforcements, the bloodied First Marine Division was withdrawn. Meanwhile, the 164th Infantry and the 2nd Marines had arrived. These were elements of the Americal Division of the U.S. Army and the Second Marine Division. Subsequently, other units of these divisions and of the 25th Infantry Division were rotated onto the island. Organizational charts for the Second marine Divison and the 25th Infantry Divison are given left and right, based on the same sources as the charts above. In December 1942, the Army command at Guadalcanal was designated the XIVth Corps, and General Patch of the Americal Division was promoted to Corps Commander. General Sebree then became the commanding officer of the Division. The Second Marine Division chart seems deficient in support units, but this is how W. Victor Madej gives it. The fighting recounted in the books and movies detailed below mainly involves these later arriving forces.
When the Guadalcanal campaign began, it was the first land offensive by the United States against any Axis power. It continued to be the only land offensive by the United States until the major Allied invasion of North Africa in November 1942. Under the "Europe first" doctrine of the Allied leadership, the material for Guadalcanal was assigned grudgingly. This made it "Operation Shoestring" to those involved. The future of the operaton was also immediately put in doubt by the disaster of the Battle of Savo Island. Nevertheless, the American public was far more incensed about Japan than about Germany and was eager for news of American attacks, after many months of American forces being defeated and captured in the Philippines, and on Wake and Guam. Thus, an account of the earliest days on Guadalcanal, Guadalcanal Diary, by combat reporter Richard Tregaskis, was a sensation, and a reasonably faithful movie version was turned out within a year (even if obviously shot in California). The land fighting on Guadalcanal was also immortalized in James Jones' The Thin Red Line, made as a movie in 1964 and recently remade by Terrence Malick in 1998.
The fighting in The Thin Red Line, however, comes from fairly late in the campaign, after the Battles of the Tenaru River, Bloody Ridge, and Henderson Field. All the early fighting was right on the perimeter of Henderson Field, with the Japanese trying to break in during night attacks. The Japanese had trouble appreciating the seriousness of the American threat. The first Japanese attack, led by Colonel Kiyono Ichiki, was the result of serious material and moral miscalculation. The Japanese believed that about a regiment of Americans had landed, not the better part of a division. Ichiki's regiment was thus sent to retake the island. Since Ichiki also believed that one good surprise night attack would cause the Americans to run, he did not even wait for his whole unit but advanced with no more than a battalion. He didn't even have the advantage of surprise and so died with nearly all his men. The next Japanese commander, Major General Kiyotake Kawaguchi was more prudent, using his own regiment and the remnants of Ichiki's with more care. He still gravely underestimated the American forces, however. The Battle of Bloody Ridge, although harrowing for the Marines, nevertheless gained the Japanese nothing of their objective.
This at last awakened the Japanese Command to the magnitude of their task. Division sized forces would be needed. Lieutenant General Harukichi Hyakutake, Commander of the 17th Army in Rabaul, decided to move himself and his headquarters to Guadalcanal. The whole 2nd Division would be brought in for an October offensive. This was the high water mark of the Japanese effort, and it came within shouting distance of success. When the battleships Kongo and Haruna bombarded Henderson Field the night of 13/14 October, their 14 inch shells all but destroyed the place, and most of its aircraft. However, between their supply problems and the jungle and terrain, the Japanese had trouble coordinating effective attacks. They failed again. The offensive for November, with the arrival of the 38th Division, never happened. Admiral Halsey committed the new battleships Washington and South Dakota to the defense of the island; and after three nights of epic fireworks in the Sound, American aircraft caught the fleet of Japanese troop transports at sea in daylight. Few Japanese reinforcements or supplies made it to the island. Although now, for the first time, the Japanese actually outnumbered the Americans, most Japanese soldiers were unfit for use, starving, diseased, and without combat supplies. No November offensive could be mounted, and that meant there would never be another.
Starting on 17 December 1942, then, American forces moved out in their own offensive to drive the Japanese off the island. The charge up grass covered slopes to capture hilltop Japanese positions, as on Mt. Austen (which fell December 24th), is the kind of action shown in Terrence Malick's movie. The Japanese retreated before such losses and soon determined to evacuate the island, which they did in the first days of February 1943. During that whole late period, the Japanese were so weakened by disease, starvation, and lack of ammunition, that they were incapable of offensive action. Some of Malick's aggressive Japanese thus look rather too well fed and equipped for authenticity; and we are given no clue about what the Japanese have already been through. A similiar problem may occur with the many prisoners Malick shows being taken. This may be true, but my understanding is that the Japanese usually fought to the death and that at this point in the war few prisoners were actually taken. On Guadalcanal, there was even an open line for Japanese retreat, a feature missing from many later Pacific island battles where few, if any, Japanese were captured alive.
In popular culture, the naval war off Guadalcanal gets less attention than the land war, even though the intensity of naval fighting was extraordinary and the fate of the land campaign depended absolutely on its outcome. This was in part due to the press coverage that the land fighting got, and to the actual secrecy that was imposed on the naval battles. Thus, the very existence of the Battle of Savo Island was kept secret for two months until the (relative) victory of Cape Esperance could be announced at the same time. Also, the naval battles were brief, confusing affairs in the dark. What was going on was not even obvious to the participants, much less to land based observers, who would only see flashes and explosions in the distance, without a clue of what was happening. Even worse, it would be difficult, even today, to portray such battles on film. There was little authentic film made at the time (most of what one keeps seeing is from later in the War), and Hollywood has never been very good at reproducing the lurching of warships, spitting fire or exploding, in the dark, cataclysmic encounters.
The organizational diagrams for Japanese forces are based on W. Victor Madej, Japanese Armed Forces Order of Battle, 1937-1945, Volume I [Game Marketing Company, Allentown, Pennsylvania, 1981], where units must be found listed under their divisions. Other information on Japanese forces is from John Toland, The Rising Sun [Bantam Books, 1971] and other books in the bibliography. Again, details of the symbols are explained at "Military Rank". Note that non-standrd symbols are used for company and platoon. Many small units included for the Japanese simply reflect pieces in the "Bloody Ridge" boardgame, which presumably have been designed to reflect what was available to Japanese forces. Madej does not give details of unit organization for Japanese forces on Guadalcanal, and, indeed, such details may not even be known, considering the attrition suffered in their delivery and the chaotic conditions that prevailed in the command on site. Also, board games rarely provide markers for non-combat support units. Thus, the diagram has been provided at right to show the standard structure of a Japanese triangular division, as detailed by Madej [pp.9-10]. It was not uncommon for mountain artillery to occur as substitutes for field artillery, as we find on Guadalcanal. While anti-tank and mortar units are common in the standard division, we do not see the anti-aircraft units that occurred on Guadalcanal. The standard division employed a great many horses. Although becoming obsolete, these were far from gone in the Japanese Army. I have not, however, heard of any horses ever being landed, used, or observed on Guadalcanal, where their use would have been pointless and their maintenance impossible. Madej's tables do not list quartermaster units. These must have existed, but perhaps were counted as part of the transport regiment.
Despite the resonance of the name of Guadalcanal, real documentary film treatments of the campaign are rare to non-existent. The first chance for anything of the sort came with the celebrated television documentary, Victory at Sea [now issued in a DVD set, from The History Channel and NBC News]. An entire (half hour) episode was devoted to Guadalcanal (broadcast December 14, 1952), but it contained absolutely no details of any of the actual fighting, on either land or sea (with unidentified footage and little better than a propaganda style narrative). The naval battles are listed, with no indication of who even won them, let alone tactical descriptions. That the events of a movie like The Thin Red Line actually occur after the most interesting and desperate period of the campaign, and after the Japanese were in no state to launch offensive action, may not even have been understood by viewers. But if Hollywood has never been good with things like the night naval battles, nothing stands in the way of genuine documentary treatment, with computer animation and informed narrative, being produced for some venue like The History Channel. When the Battle of the Little Bighorn, or the Gunfight at the OK Corral, has been gone over virtually minute by minute, there is no good reason why the Battle of Savo Island should not get the same treatment.
In the following table, beginning September 11, the right hand column indicates the moves, two days each, in the wargame. With the moves, the arrival of Japanese reinforcements is also indicated. The arrival of Japanese forces is estimated for dates prior to September 11, and for reinforcements after the end of the game on November 2. The notation is in battalions and regiments, e.g. "2/28" indicates the second battalion of the Japanese 28th infantry regiment -- the first Japanese force to respond to the arrival of the Americans, and the one involved in Ichiki's suicidal attack on August 21st. Only Japanese forces are shown because the Japanese strategic problem was the main interest when I originally drew up the table.
The Battles of the Eastern Solomons and of the Santa Cruz Islands are the two great carrier battles of the period. These are not as famous as the Coral Sea or Midway but are two out of the five great carrier battles (with the very one-sided Battle of the Philippine Sea in 1944) of World War II. Santa Cruz was the very last carrier battle of the War between roughly equal sides, and it is where the carrier Hornet, which helped launch the Doolittle Raid against Tokyo (18 April 1942), was sunk. Since the Battle of the Coral Sea had also been fought in the area of the Solomons (the first naval battle in history in which opposing ships didn't even see each other), a study of carrier tactics necessarily means a study of the War in this area.
On the chronological chart below, the major land battles of the Guadalcanal campaign are in bold red; the major sea battles in bold blue. Entries on lines between dates are for night actions. Events in the fighting elsewhere in the Solomons (e.g. Munda) and on New Guinea (e.g. Port Moresby, Milne Bay, Buna, & Lae) are also indicated, with the New Guinea items all in green. Japanese land units on Guadalcanal are given in orange. "Scens" in the chronology are the scenarios, marked in purple, of the board game. Scenario 1 is the Battle of Bloody Ridge; scenario 2 is the Battle for Hendrson Field; and scenario 3 is the "campaign" game covering both. As noted, another Scenario for a November offensive would have been nice. If the American offensive beginning in December had been covered also, a larger map, west to Cape Esperance, would have been necessary.

While to anyone particularly taken with the Guadalcanal and Solomons campaigns the events on New Guinea may seem like a sideshow, this was hardly the case. The whole campaign in the area began over New Guinea. The Battle of the Coral Sea occurred when a Japanese force on the way to Port Moresby was intercepted. Although the battle cost both sides an aircraft carrier, the American loss, of the Lexington, was more severe than the Japanese, the small support carrier Shoho. Nevertheless, the Allied purpose of the battle was achieved, since the Japanese landing force was withdrawn. With the simultaneous Japanese occupation of the Bismarks and Solomons, Port Moresby was the last Australian base in the area. Its loss would have been disastrous, and the Japanese knew it. So in the course of the Guadalcanal campaign, we see the Japanese renewing their efforts in New Guinea -- but then being thrown back by the Australians and Americans. On 25 August 1942, the Japanese landed at Milne Bay, on the eastern tip of Papua -- the long peninsula at the end of New Guinea. The attack was repulsed and the Japanese evacuated by 6 September. Their next effort was an ambitious overland attack across the Owen Stanley Range, from Gona directly to Port Moresby, with the mountains, jungle, mud, and disease posing barriers far beyond what any enemy could arrange. By 17 September, Japanese forces had reached Ioribaiwa, 32 miles from Port Moresby. On 26 September, however, they were defeated and began a long retreat back the way they came. The Allies went over to the offensive, and as the Americans stopped the Japanese on Guadalcanal and began to sweep them from the island, Australians and Americans began to sweep the Japanese from Papua. By 22 January 1943, Japanese resistance had collapsed. While the Solomons campaign was under the direction of Admiral Nimitz in Honolulu, New Guinea was the domain of General MacArthur in Australia. MacArthur continued to move to the north shore of New Guinea. Just before the American landing at Emperss Augusta Bay in Bougainville, Salamana and Lae had fallen. MacArthur continued west on New Guinea, heading ultimately, of course, for the Philippines.
The first American units in Australia and New Guinea were the 32nd and 41st Divisions, organized under the I Corps. Not all participated in New Guinea all at once, but parts of the divisions were committed as needed. The organizational diagram for the Corps at right is based on W. Victor Madej, U.S. Army Order of Battle, Pacific Theater of Operations, 1941-1945 [Game Publishing Company, Allentown, Pennsylvania, 1984, p.22]. I do not have organizational information for the Australian units in the campaign.
