“Dinah Might,” the first crippled B-29 to make an emergency landing on Iwo Jima during the fighting, is surrounded by Marines and Seabees on 4 March 1945.
Among the veterans preparing for Iwo Jima were two Medal of Honor recipients from the Guadalcanal campaign, Gunnery Sergeant John “Manila John” Basilone and Lieutenant Colonel Robert E. Galer. Headquarters Marine Corps preferred to keep such distinguished veterans in the states for morale purposes, but both men wrangled their way back overseas—Basilone leading a machine gun platoon, Galer delivering a new radar unit for employment with the Landing Force Air Support Control Unit.
The Guadalcanal veterans would only shake their heads at the abundance of amphibious shipping available for Operation Detachment. Admiral Turner would command 495 ships, of which fully 140 were amphibiously configured, the whole array 10 times the size of Guadalcanal’s task force. Still there were problems. So many of the ships and crews were new that each rehearsal featured embarrassing collisions and other accidents. The new TD-18 bulldozers were found to be an inch too wide for the medium landing craft (LCMs). The newly modified M4A3 Sherman tanks proved so heavy that the LCMs rode with dangerously low freeboards. Likewise, 105mm howitzers overloaded the amphibious trucks (DUKWs) to the point of near-unseaworthiness. These factors would prove costly in Iwo’s unpredictable surf zone.
These problems notwithstanding, the huge force embarked and began the familiar move to westward. Said Colonel Robert E. Hogaboom, Chief of Staff, 3d Marine Division, “we were in good shape, well trained, well equipped and thoroughly supported.”
On Iwo Jima, General Kuribayashi had benefitted from the American postponements of Operation Detachment because of delays in the Philippines campaign. He, too, felt as ready and prepared as possible. When the American armada sailed from the Marianas on 13 February, he was forewarned. He deployed one infantry battalion in the vicinity of the beaches and lower airfield, ordered the bulk of his garrison into its assigned fighting holes, and settled down to await the inevitable storm.
An aerial view of Iwo Jima before the landing clearly shows “pork chop” shape. Mount Suribachi, in the right foreground, is at the southern end of the island.

Two contentious issues divided the Navy-Marine team as D-day at Iwo Jima loomed closer. The first involved Admiral Spruance’s decision to detach Task Force 58, the fast carriers under Admiral Marc Mitscher, to attack strategic targets on Honshu simultaneously with the onset of Admiral Blandy’s preliminary bombardment of Iwo. The Marines suspected Navy-Air Force rivalry at work here—most of Mitscher’s targets were aircraft factories which the B-29s had missed badly a few days earlier. What the Marines really begrudged was Mitscher taking all eight Marine Corps fighter squadrons, assigned to the fast carriers, plus the new fast battleships with their 16-inch guns. Task Force 58 returned to Iwo in time to render sparkling support with these assets on D-day, but two days later it was off again, this time for good.
