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.

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.
