Battle of Iwo Jima Archive to include 1) 4 Oblique Photograph sheets numbered 1-4 showing different sections of the Island with sheet 1 showing Green I and Red I sections. Sheets 2 showing Red 1, Red 2 and Yellow 1. Sheet 3 showing Yellow 1 and Yellow 2 sections and sheet 4 showing Blue 1 and Blue 2 All four measures 17 X 20 inches and in excellent condition 2) Sheets 1 - 3 showing the Island of Iwo Jima, all marked SECRET measuring 20 X 22 1/2. Due to the SECRET marking on this D-Day Iwo Jima invasion chart only a very limited number were produced before the invasion with only a small handful still believed to exist today with most being in high-end private museum collections. This Iwo Jima invasion beach chart is as rare and sought after as the TOP SECRET D-Day invasion of Normandy BIGOT maps and the SECRET Iwo Jima Beach Diagram maps. Green Beach (Green 1)Location: The Green Beach zone was located on the extreme left (southwestern end) of the landing area, right at the base of Mount Suribachi.Assigned Units: The 28th Marine Regiment, 5th Marine Division, was assigned to land on Green Beach.Objective: The primary objective for the Marines landing on Green Beach was to isolate Mount Suribachi from the rest of the island by cutting off the narrow neck of land connecting it to the central part of Iwo Jima. This was crucial to preventing Japanese forces on the mountain from reinforcing other parts of the island.Challenges: Green Beach was heavily defended by Japanese artillery and machine-gun positions on Mount Suribachi. The black volcanic sand made movement difficult, and the steep incline toward the mountain posed additional challenges.Red Beach (Red 1 and Red 2)Location: Red Beach was divided into two zones, Red 1 and Red 2, and covered the central portion of the landing area, just north of Green Beach. These zones were located in front of the heavily fortified area known as the “Meat Grinder.”Assigned Units: The 27th Marine Regiment, 5th Marine Division, was assigned to land on Red 1 and Red 2.Objective: The objective for the units landing on Red Beach was to advance inland to capture the Japanese airfield number 1 and push toward the island's central plateau. Securing this area would provide a staging ground for further advances toward the northern part of the island.Challenges: The beaches in this zone were subjected to intense Japanese artillery and machine-gun fire from multiple directions, including Mount Suribachi to the south and fortified positions in the "Meat Grinder" to the north. The Marines also faced heavy resistance from Japanese defenders entrenched in bunkers and pillboxes.This extremely rare and museum-grade "SECRET" marked WWII Battle of Iwo Jima D-Day amphibious beach diagram vividly illustrates the intensive planning and operational accuracy that went behind Operation Detachment. Titled "Oblique Photographs - South Eastern Beaches Iwo Jima" this original SECRET Iwo Jima D-Day beach diagram was 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.This SECRET Iwo Jima D-Day amphibious beach diagram was the original intelligence document used to make the infamous SECRET Iwo Jima invasion map. These were the Iwo Jima invasion intelligence documents used to make that exact map.It shows little in the way of manmade impediments to amphibious invasion, belying the extensive Japanese fortifications and the dogged resistance that the Marines would face from the roughly 20,000 defenders. Eschewing Japanese doctrine, which called for him to contest every inch of the landing beaches, the commanding Lieutenant General Tadamichi Kuribayashi instead instructed his soldiers to allow the American forces to land en masse, before springing traps to kill as many newly-landed troops as possible.American planners also misunderstood the nature of the volcanic sand and terrain of the beaches, most of which was thought to be perfectly suitable for disembarking and traversing. In these diagrams, little mention is made of the softness of this sand, and few obstacles are listed. In reality, the ash was very difficult to traverse, and equally difficult to dig into, greatly complicating the unloading of equipment and vehicles and the excavation of foxholes and trenches.These errors were symptomatic of a general lack of accurate pre-invasion intelligence, which ultimately cost hundreds, even thousands of American lives.The Role of Oblique Photograph Secret Invasion Beach Diagram Maps:In preparation for
