GUADALCANAL

Despite suffering a resounding defeat at Midway in June 1942, the Japanese remained a fearsome adversary. Not only did they outnumbered US forces in every corner of the Pacific, efforts on the American home front to scale up for war were still in their infancy, and large volumes of new troops, ships, and planes had not yet arrived in the Pacific Theater.

The war would not wait, as an important discovery in the South Pacific prompted the first major US offensive. A reconnaissance flight had spotted the construction of a Japanese airfield on Guadalcanal, a sprawling island in the Solomon Islands, from where long-range bombers could disrupt shipping traffic between the United States and Australia, a key US ally. In August 1942, 11,000 men of the 1st Marine Division landed on Guadalcanal, seizing the lightly defended and unfinished airfield after a short march inland.

The Japanese had few forces on Guadalcanal but a substantial air base at Rabaul, just 550 miles away. They launched air strikes against the American support ships operating offshore, and though naval fighter planes warded off most of the attackers, the US aircraft carriers were forced to withdraw after heavy losses among their fighter groups. Hours later, Japanese ships sank four American and Australian cruisers in nighttime action, killing 1,200 Allied sailors. The remaining US ships fled for safer waters, leaving the Marines on Guadalcanal entirely isolated with no support and little food and ammunition.

As the Marines dug into their perimeter defenses—the reinforced Japanese were determined to re-take the position—naval construction troops, known as Seabees, hurried to finish construction of the airstrip so air support could arrive. The moment it was operational, Marine fighter planes and dive-bombers touched down, providing a substantial boost to the ground defenses. The pilots flew their battered planes from sunup to sundown, dueling daily with the Japanese in the skies above and pouncing on enemy barges and ships ferrying additional troops and supplies to the island.

For six months, the battle raged on the ground, at sea, and in the air. The Japanese troops on the island were unable to dislodge the Americans and as their own numbers and supplies dwindled, they resorted to desperate banzai charges. The frenzied, midnight raids, led by sword-waving officers, unnerved the Marines but they stood their ground each time, pouring machine-gun fire into the oncoming attackers. The number of Japanese dead rose rapidly, and by February 1943, Tokyo recognized the futility of further action and ordered all remaining troops evacuated from the island.

Both sides paid a steep price for that single airstrip, with the Japanese losing more than 24,000 men on the island. American ground casualties were far fewer, but each side lost thousands more in the ongoing sea and air battles. The battle ended decisively in favor of the United States, but the ferocity among the Japanese foreshadowed the grim work ahead in pushing the enemy back across the Pacific.

In each US military service, a pilot was deemed an “ace” after downing five enemy aircraft. During the battle for Guadalcanal, Marine Captain Joseph J. Foss shot down twenty-six Japanese planes in just six weeks. Foss was twenty-seven years old.

Bushido

Throughout the Pacific campaign, Japanese officers facing imminent defeat would often order entire companies and regiments to storm fortified American positions with just swords and bayonet-tipped rifles. The irrationality of these banzai charges baffled their American foes, but such sacrifice was the product of a value system foreign to Westerners and deeply rooted in Japanese culture and tradition. For centuries, an ethos known as bushido guided the samurai, Japan’s elite warrior class, emphasizing honor and loyalty above all else, including life. As the Imperial Army rose to prominence in the pre-war years, officers embraced this heritage, pledging themselves to the emperor, a deity they considered a living god.

When the Japanese vowed to fight to the end on the emperor’s behalf, it was not death they feared in serving him, but dishonor. When defeat loomed, the Japanese devoted themselves to either falling in battle, viewed as an honorable death, or committing seppuku (ritualistic suicide) to atone for battlefield failures. With few willing to surrender—an act considered disgraceful, and under bushido, punishable by death—officers turned to banzai charges instead, convinced bushido and their willingness to sacrifice themselves gave them an edge against Americans consumed with fears of death. Such devotion, however, could not overcome American firepower, and on island after island, failed banzai charges only hastened the collapse of Japanese resistance.

Competing naval forces battled for months around Guadalcanal, with the two sides losing a combined fifty ships. So many sunken wrecks filled the adjoining waters, the area became known as Iron Bottom Sound. Among the victims were two US aircraft carriers – the USS Wasp, recently transferred from the Atlantic Fleet, and the USS Hornet, which carried the famed Doolittle Raiders to Japanese waters just months earlier.
