These extremely rare and museum-grade "SECRET" marked WWII Battle of Iwo Jima D-Day amphibious beach diagrams vividly illustrates the intensive planning and operational accuracy that went behind Operation Detachment. Titled "Oblique Photographs - South Eastern Beaches Iwo Jima" these original SECRET Iwo Jima D-Day beach diagrams were prepared by the Intelligence Section Amphibious Forces Pacific only a few months before the D-Day invasion of Iwo Jima in February 1945. These Iwo Jima invasion beach diagrams were studied and used by Captains of Landing Craft Infantry (LCI) and the initial waves of U.S. Marines set to land on their designated black sand beachheads. These invasion maps were vital to the initial landing success as they not only showed the visual views for the designated beachheads, but they also noted all of the updated Japanese defenses on Iwo Jima near that designated landed sector.
