The Marines fired an unprecedented half million artillery rounds in direct and general support of the assault units. More rounds were lost when the 5th Marine Division dump blew up. The flow never stopped. The Shore Party used DUKWs, LVTs, and larger craft for rapid offloading of ammunition ships dangerously exposed to Iwo Jima’s enemy gunners. Marine Corps ammunition and depot companies hustled the fresh munitions ashore and into the neediest hands.
Lieutenant Colonel James D. Hittle, USMC, served as D-4 of the 3d Marine Division throughout the battle of Iwo Jima. While shaking his head at the “crazy-quilt” logistic adaptations dictated by Iwo’s geography, Hittle saw creative staff management at all levels. The 3d Division, earmarked as the reserve for the landing, found it difficult to undertake combat loading of their ships in the absence of a scheme of maneuver on shore, but the staff made valid assumptions based on their earlier experiences. This paid huge dividends when the corps commander had to commit the 21st Marines as a separate tactical unit well in advance of the division. Thanks to foresightful combat loading, the regiment landed fully equipped and supported, ready for immediate deployment in the fighting.
To augment the supplies coming across the beach, the 3d Division staff air officer “appropriated” a transport plane and made regular runs to the division’s base in Guam, bringing back fresh beef, mail, and cases of beer. The 3d Division G-4 also sent his transport quartermaster (today’s embarkation officer) out to sea with an LVT-full of war souvenirs; these were bartered with ship’s crews for donations of fresh fruit, eggs, bread—“we’d take anything.” General Erskine distributed these treats personally to the men in the lines.
Retired Brigadier General Hittle marveled at the density of troops funnelled into the small island. “At one point we had 60,000 men occupying less than three-and-a-half square miles of broken terrain.” These produced startling neighbors: a 105mm battery firing from the middle of the shore party cantonment; the division command post sited 1,000 yards from Japanese lines; “giant B-29s taking off and landing forward of the CP of an assault regiment.”
In the effort to establish a fresh-water distilling plant, Marine engineers dug a “well” near the beach. Instead of a source of salt water the crew discovered steaming mineral water, heated by Suribachi’s supposedly dormant volcano. Hittle moved the 3d Division distilling site elsewhere; this spot became a hot shower facility, soon one of the most popular places on the island.

Iwo Jima’s Costs, Gains, and Legacies
In its 36 days of combat on Iwo Jima, the V Amphibious Corps killed approximately 22,000 Japanese soldiers and sailors. The cost was staggering. The assault units of the corps—Marines and organic Navy personnel—sustained 24,053 casualties, by far the highest single-action losses in Marine Corps history. Of these, a total of 6,140 died. Roughly one Marine or corpsman became a casualty for every three who landed on Iwo Jima.
