Immediate Pre-Invasion, SECRET Map Set Showing the Landing Beaches and Defenses on Okinawa.
Fantastic set of three color-printed maps (the complete set) "prepared at the request of 10th ARMY" showing the west coast of Okinawa and the extent of the U.S. landing beaches on the island. The map was produced by the U.S. Navy Photographic Interpretation Squadron Two (Interpron Two) with revisions to March 14-19, 1945. The base map is AMS-2 Revised to January 1945, the defenses shown were updated through March 1, 1945.
The map shows roughly 30 miles of coastline on the western side of Okinawa, from the major city of Naha and the Naha airfield in the south, through Katena (Kadena) Airfield, to the northeast of the Yontan Airfield in the north. The map illustrates the landing zones and beaches; they are labeled Beach Black 1-6, Beach Green 1-2, Beach Red 1-3, Beach Blue 1-2, Beach Yellow 1-3, Beach Purple 1-2, Beach Orange 1-2, Beach White 1-3, and Beach Brown 1-4. At Beach Orange 1 and 2 there is a pencil manuscript note: "2 Phototeams and lab | AP 203 3 Apr. | LST 890 5 Apr."
The map is classified SECRET, with the typical declaration that it would become RESTRICTED in the combat zone.

The United States Army and Marine Corps landed on Okinawa on April 1, 1945, as the specially-created 10th Army; the landing was the largest amphibious assault in the Pacific Theater during World War II. The Battle of Okinawa, codenamed Operation Iceberg, lasted for 82 days after the landing, to June 1945. The Battle claimed the lives of 14,009 to 20,195 American personnel and between 77,166 and 110,000 Japanese. After a long campaign of island hopping, the Allies were planning to use Kadena Air Base on the large island of Okinawa as a base for Operation Downfall, the planned invasion of the Japanese home islands, 340 miles away.
