campaign. During the top-level planning stage he was often, as always, a “voice in the wilderness,” predicting severe casualties unless greater and more effective preliminary naval bombardment was provided. He diverted the press and the visiting dignitaries from Schmidt, always providing realistic counterpoints to some of the rosier staff estimates. “It’s a tough proposition,” Smith would say about Iwo, “That’s why we are here.”

      General Schmidt, whose few public pronouncements left him saddled with the unfortunate prediction of a 10-day conquest of Iwo Jima, came to resent the perceived role Holland Smith played in post-war accounts. As he would forcibly state:

      I was the commander of all troops on Iwo Jima at all times. Holland Smith never had a command post ashore, never issued a single order ashore, never spent a single night ashore. … Isn’t it important from an historical standpoint that I commanded the greatest number of Marines ever to be engaged in a single action in the entire history of the Marine Corps?

      General Smith would not disagree with those points. Smith provided a useful role, but Schmidt and his exceptional staff deserve maximum credit for planning and executing the difficult and bloody battle of Iwo Jima.

      The V Amphibious Corps achievement was made even more memorable by the enormously difficult opposition provided by the island and the enemy. In Lieutenant General Tadamichi Kuribayashi [see sidebar], the Americans faced one of the most formidable opponents of the war. A fifth-generation samurai, hand-picked and personally extolled by the Emperor, Kuribayashi combined combat experience with an innovative mind and an iron will. Although this would be his only combat against American forces, he had learned much about his prospective opponents from earlier service in the United States. More significantly, he could appraise with an unblinking eye the results of previous Japanese attempts to repel American invasions of Japanese-held garrisons. Heroic rhetoric aside, Kuribayashi saw little to commend the “defend-at-the-water’s-edge” tactics and “all-or-nothing” Banzai attacks which had characterized Japan’s failures from Tarawa to Tinian. Kuribayashi, a realist, also knew not to expect much help from Japan’s depleted fleet and air forces. His best chances, he concluded, would be to maximize Iwo’s forbidding terrain with a defense in depth, along the pattern of the recent Biak and Peleliu defensive efforts. He would eschew coast defense, anti-landing, and Banzai tactics and instead conduct a prolonged battle of attrition, a war of nerves, patience, and time. Possibly the Americans would lose heart and abandon the campaign.

      Such a seemingly passive policy, even that late in the war, seemed revolutionary to senior Japanese Army and Navy leaders. It ran counter to the deeply ingrained warrior code, which viewed the defensive as only an unpleasant interim pending resumption of the glorious offensive in which one could destroy the enemy with sword and bayonet. Even Imperial General Headquarters grew nervous. There is some evidence of a top-level request for guidance in defending against American “storm landings” from Nazi Germany, whose sad experience in trying to defend Normandy at the water’s edge had proven disastrous. The Japanese remained unconvinced. Kuribayashi needed every bit of his top connections with the Emperor to keep from being summarily relieved for his radical proposals. His was not a complete organizational victory—the Navy insisted on building gun casemates and blockhouses along the obvious landing beaches on Iwo—but in general he prevailed.

      Kuribayashi demanded the assistance of the finest mining engineers and fortifications specialists in the Empire. Here again, the island favored the defender. Iwo’s volcanic sand mixed readily with cement to produce superior concrete for installations; the soft rock lent itself to rapid digging. Half the garrison lay aside their weapons to labor with pick and spade. When American heavy bombers from the Seventh Air Force commenced a daily pounding of the island in early December 1944, Kuribayashi simply moved everything—weapons, command posts, barracks, aid stations—underground. These engineering achievements were remarkable. Masked gun positions provided interlocking fields of fire, miles of tunnels linked key defensive positions, every cave featured multiple outlets and ventilation tubes. One installation inside Mount Suribachi ran seven stories deep. The Americans would rarely see a live Japanese on Iwo Jima until the bitter end.

      American intelligence experts, aided by documents captured in Saipan and by an almost daily flow of aerial photography (and periscope-level pictures from the submarine Spearfish), puzzled over the “disappearing act” of the Japanese garrison. Trained photo interpreters, using stereoscopic lenses, listed nearly 700 potential targets, but all were hardened, covered, masked. The intelligence staffs knew there was no fresh water available on the island. They could see the rainwater cisterns and they knew what the average monthly rainfall would deliver. They concluded the garrison could not possibly survive under those conditions in numbers greater than 12,000 or 13,000. But Kuribayashi’s force was twice that size. The men existed on half-rations of water for months before the battle began.

      Unlike earlier amphibious assaults at Guadalcanal and Tarawa, the Americans would not enjoy either strategic or tactical surprise at Iwo Jima. Japanese strategists concluded Iwo Jima would be invaded soon after the loss of the Marianas. Six months before the battle, Kuribayashi wrote his wife, “The Americans will surely invade this Iwo Jima … do not look for my return.” He worked his men ruthlessly to complete all defensive and training preparations by 11 February 1945—and met the objective. His was a mixed force of veterans and recruits, soldiers and sailors. His artillerymen and mortar crews were among the best in the Empire. Regardless, he trained and disciplined them all. As the Americans soon discovered, each fighting position contained the commander’s “Courageous Battle Vows” prominently posted above the firing apertures. Troops were admonished to maintain their positions and exact 10 American lives for every Japanese death.

      General Schmidt issued VAC Operation Plan 5–44 on 23 December 1944. The plan offered nothing fancy. Mount Suribachi dominated both potential beaches, but the 3,000 yards of black sand along the southeastern coast appeared more sheltered from the prevailing winds. Here the V Amphibious Corps would land on D-day, the 4th Marine Division on the right, the 5th on the left, the 3d in reserve. The initial objectives included the lower airfield, the west coast, and Suribachi. Then the force would swing into line and attack north, shoulder to shoulder.

      Anticipation of a major Japanese counterattack the first night influenced the landing plan. “We welcome a counterattack,” said Holland Smith, “That’s generally when we break their backs.” Both Schmidt and 4th Marine Division commander Major General Clifton B. Cates knew from recent experience at Tinian how capable the Japanese were at assembling large reserves at potential soft points along a fresh beachhead. The assault divisions would plan to land their artillery regiments before dark on D-day in that contingency.

      IWO JIMA

      (SULPHUR ISLAND)

      The physical separation of the three divisions, from Guam to Hawaii, had no adverse effect on preparatory training. Where it counted most—the proficiency of small units in amphibious landings and combined-arms assaults on fortified positions—each division was well prepared for the forthcoming invasion. The 3d Marine Division had just completed its participation in the successful recapture of Guam; field training often extended to active combat patrols to root out die-hard Japanese survivors. In Maui, the 4th Marine Division prepared for its fourth major assault landing in 13 months with quiet confidence. Recalled Major Frederick J. Karch, operations officer for the 14th Marines, “we had a continuity there of veterans that was just unbeatable.” In neighboring Hawaii, the 5th Marine Division calmly prepared for its first combat experience. The unit’s newness would prove misleading. Well above half of the officers and men were veterans, including a number of former Marine parachutists and a few Raiders who had first fought in the Solomons. Lieutenant Colonel Donn J. Robertson took command of the 3d Battalion, 27th Marines, barely two weeks before embarkation and immediately ordered it into the field for a sustained live-firing exercise. Its competence and confidence impressed him. “These were professionals,” he concluded.
