The infantry, heavily laden, found its own “foot-mobility” severely restricted. In the words of Corporal Edward Hartman, a rifleman with the 4th Marine Division: “the sand was so soft it was like trying to run in loose coffee grounds.” From the 28th Marines came this early, laconic report: “Resistance moderate, terrain awful.”
The rolling barrage and carefully executed landing produced the desired effect, suppressing direct enemy fire, providing enough shock and distraction to enable the first assault waves to clear the beach and begin advancing inward. Within minutes 6,000 Marines were ashore. Many became thwarted by increasing fire over the terraces or down from the highlands, but hundreds leapt forward to maintain assault momentum. The 28th Marines on the left flank had rehearsed on similar volcanic terrain on the island of Hawaii. Now, despite increasing casualties among their company commanders and the usual disorganization of landing, elements of the regiment used their initiative to strike across the narrow neck of the peninsula. The going became progressively costly as more and more Japanese strongpoints along the base of Suribachi seemed to spring to life. Within 90 minutes of the landing, however, elements of the 1st Battalion, 28th Marines, had reached the western shore, 700 yards across from Green Beach. Iwo Jima had been severed—“like cutting off a snake’s head,” in the words of one Marine. It would represent the deepest penetration of what was becoming a very long and costly day.
The other three regiments experienced difficulty leaving the black sand terraces and wheeling across towards the first airfield. The terrain was an open bowl, a shooting gallery in full view from Suribachi on the left and the rising tableland to the right. Any thoughts of a “cakewalk” quickly vanished as well-directed machine-gun fire whistled across the open ground and mortar rounds began dropping along the terraces. Despite these difficulties, the 27th Marines made good initial gains, reaching the southern and western edges of the first airfield before noon. The 23d Marines landed over Yellow Beach and sustained the brunt of the first round of Japanese combined arms fire. These troops crossed the second terrace only to be confronted by two huge concrete pillboxes, still lethal despite all the pounding. Overcoming these positions proved costly in casualties and time. More fortified positions appeared in the broken ground beyond. Colonel Walter W. Wensinger’s call for tank support could not be immediately honored because of trafficability and congestion problems on the beach. The regiment clawed its way several hundred yards towards the eastern edge of the airstrip.
No assault units found it easy going to move inland, but the 25th Marines almost immediately ran into a buzz-saw trying to move across Blue Beach. General Cates had been right in his appraisal. “That right flank was a bitch if there ever was one,” he would later say. Lieutenant Colonel Hollis W. Mustain’s 1st Battalion, 25th Marines, managed to scratch forward 300 yards under heavy fire in the first half hour, but Lieutenant Colonel Chambers’ 3d Battalion, 25th Marines, took the heaviest beating of the day on the extreme right trying to scale the cliffs leading to the Rock Quarry. Chambers landed 15 minutes after H-hour. “Crossing that second terrace,” he recalled, “the fire from automatic weapons was coming from all over. You could’ve held up a cigarette and lit it on the stuff going by. I knew immediately we were in for one hell of a time.”

Tracked landing vehicles (LVTs), jam-packed with 4th Marine Division troops, approach the Line of Departure at H-hour on D-day. In the center rear can be seen the control vessels which attempted to maintain order in the landing.
This was simply the beginning. While the assault forces tried to overcome the infantry weapons of the local defenders, they were naturally blind to an almost imperceptible stirring taking place among the rocks and crevices of the interior highlands. With grim anticipation, General Kuribayashi’s gunners began unmasking the big guns—the heavy artillery, giant mortars, rockets, and anti-tank weapons held under tightest discipline for this precise moment. Kuribayashi had patiently waited until the beaches were clogged with troops and material. Gun crews knew the range and deflection to each landing beach by heart; all weapons had been preregistered on these targets long ago. At Kuribayashi’s signal, these hundreds of weapons began to open fire. It was shortly after 1000.
