Two aspects of the battle remain controversial: the inadequate preliminary bombardment and the decision to use piecemeal replacements instead of organized units to strengthen the assault forces. Both decisions, rendered in the context of several competing factors, were made by experienced commanders in good faith. Unavoidably, Iwo Jima’s biggest cost to the V Amphibious Corps was the loss of so many combat veterans in taking the island. While the battle served to create a new generation of veterans among the survivors, many proud regiments suffered devastating losses. With these same units already designated as key components of the landing force against the Japanese home islands, such losses had serious potential implications. These factors may well have influenced General Holland Smith’s unpopular decision to withhold the 3d Marines from the battle. From the perspective of an exhausted company commander on Iwo Jima, Smith’s decision seemed inexcusable, then and now; from the wider perspective of the commanding general, Fleet Marine Forces, Pacific, the decision makes more sense.
Whatever his shortcomings, Holland Smith probably knew amphibious warfare better than anyone. Of the hundreds of after-action reports filed immediately following the battle, his official analysis best captured the essence of the struggle:
There was no hope of surprise, either strategic or tactical. There was little possibility for tactical initiative; the entire operation was fought on what were virtually the enemy’s own terms.... The strength, disposition, and conduct of the enemy’s defense required a major penetration of the heart of his prepared positions in the center of the Motoyama Plateau and a subsequent reduction of the positions in the difficult terrain sloping to the shore on the flanks. The size and terrain of the island precluded any Force Beachhead Line. It was an operation of one phase and one tactic. From the time the engagement was joined until the mission was completed it was a matter of frontal assault maintained with relentless pressure by a superior mass of troops and supporting arms against a position fortified to the maximum practical extent.
We Americans of a subsequent generation in the profession of arms find it difficult to imagine a sustained amphibious assault under such conditions. In some respects the fighting on Iwo Jima took on the features of Marines fighting in France in 1918, described by one as “a war girt with horrors.” We sense the drama repeated every morning at Iwo, after the prep fires lifted, when the riflemen, engineers, corpsmen, flame tank crews, and armored bulldozer operators somehow found the fortitude to move out yet again into “Death Valley” or “The Meatgrinder.” Few of us today can study the defenses, analyze the action reports, or walk the broken ground without experiencing a sense of reverence for the men who won that epic battle.
Fleet Admiral Nimitz said these words while the fighting still raged: “Among the Americans who served on Iwo Jima, uncommon valor was a common virtue,” a sentiment now chiseled in granite at the base of Felix de Weldon’s gigantic bronze sculpture of the Suribachi flag-raising.
Twenty-two Marines, four Navy corpsmen, and one LCI skipper were awarded the Medal of Honor for utmost bravery during the battle of Iwo Jima. Half were posthumous awards.
General Erskine placed these sacrifices in perspective in remarks made during the dedication of the 3d Marine Division cemetery on the embattled island:
Victory was never in doubt. Its cost was. What was in doubt, in all our minds, was whether there would be any of us left to dedicate our cemetery at the end, or whether the last Marine would die knocking out the last Japanese gunner.
