This was the general situation previously described at the unsuspected “turning point” on 4 March (D+13) when, despite sustaining frightful losses, the Marines had chewed through a substantial chunk of Kuribayashi’s main defenses, forcing the enemy commander to shift his command post to a northern cave. This was the afternoon the first crippled B-29 landed. In terms of American morale, it could not have come at a better time. General Schmidt ordered a general standdown on 5 March to enable the exhausted assault forces a brief respite and the opportunity to absorb some replacements.

General Schmidt, now faced with losses approaching the equivalent of one entire division, again urged General Smith to release the 3d Marines. While each division had been assigned a replacement draft of several thousand Marines, Schmidt wanted the cohesion and combat experience of Colonel James M. Stuart’s regimental combat team. Holland Smith believed that the replacement drafts would suffice, presuming that each man in these hybrid units had received sufficient infantry training to enable his immediate assignment to front-line outfits. The problem lay in distributing the replacements in small, arbitrary numbers--not as teamed units--to fill the gaping holes in the assault battalions. The new men, expected to replace invaluable veterans of the Pacific War, were not only new to combat, but they also were new to each other, an assortment of strangers lacking the life-saving bonds of unit integrity. “They get killed the day they go into battle,” said one division personnel officer in frustration. Replacement losses within the first 48 hours of combat were, in fact, appalling. Those who survived, who learned the ropes and established a bond with the veterans, contributed significantly to the winning of the battle. The division commanders, however, decried the wastefulness of this policy and urged unit replacements by the veteran battalions of the 3d Marines. As General Erskine recalled: I asked the question of Kelly Turner and Holland Smith and the usual answer was, “You got enough Marines on the island now; there are too damn many here.” I said, “The solution is very easy. Some of these people are very tired and worn out, so take them out and bring in the 3d Marines.” And they practically said, “You keep quiet--we’ve made the decision.” And that was that.
