What Japanese Commanders Wrote When the American Line Never Broke

The Imperial Japanese Army went into Guadalcanal holding a conviction they had written into their own war plans: the American soldier was soft, comfortable, and would collapse the moment steel came at him. They did not guess at this — they had built their entire Pacific strategy on it. What came back from the jungle, from the ridges, and from the diaries of their own dead, was something their doctrine had no category for. In the summer and fall of 1942, three successive Japanese commands — Colonel Kiyonao Ichiki's 28th Infantry Regiment veterans of China and Singapore, Major General Kiyotake Kawaguchi's 35th Infantry Brigade of some 6,000 men, and Lieutenant General Masao Maruyama's full Sendai Division of over 20,000 — were fed one by one into the Marine perimeter around Henderson Field on Guadalcanal, Solomon Islands. At the Battle of the Tenaru on August 21, at Edson's Ridge (Bloody Ridge) on September 12–14, and at the Battle for Henderson Field on October 24–25, the 1st Marine Division under Major General Alexander Vandegrift held the line against night assaults that had broken larger armies in Malaya and the Philippines. The 5th Battalion, 11th Marines artillery — later reinforced by 155mm howitzers — fired barrages so sustained that crews stripped bare and poured water on the tubes to keep them in action. Sergeant John Basilone fed his Browning M1917 heavy machine guns through the dark at the Tenaru and again on the ridge south of the airfield, earning the Medal of Honor. Sergeant Major Jacob Vouza, a Solomon Islander scout, delivered intelligence that stripped Ichiki's approach of surprise. Merritt Edson walked his line under fire and bent the ridge into a fortress. Operation Ke — Japan's brilliantly disguised evacuation in February 1943 — rescued nearly 11,000 skeletal survivors, but it could not rescue the idea that had sent them there. The captured diaries, translated by Nisei interpreters, recorded the whole descent: from the certainty of quick conquest to the soldiers' own name for the island — Starvation Island — written in the hands of men who did not expect to leave.
