The Cache Series: Each of the first four "Codename" cache locations are themed after a major battle, or campaign, from World War II. To unlock the fifth, and final, location you will need to decipher the clues (located in each cache lid) at each cache site. There will be a different clue at each site that coincides with the history lesson in each cache description. Once you decipher the clues you will be left with four letters (don't mess up the order) which will unlock the combination lock to the fifth, final, cache. This is the the THIRD cache in the series and the letter you decipher from the history lesson below will be the third letter in the final combination. (Remember: Don't go to the "finale" until you have the combination; could be a pointless trip)
History Lesson: The Battle of Okinawa, codenamed Operation Iceberg, was fought on the islands of Okinawa and was the largest amphibious assault in the Pacific Theater of war. The 82-day long battle lasted from early April until mid-June 1945 between the United States and Japanese forces. After a long campaign of island hopping, the Allies were approaching Japan, and planned to use Okinawa as a base for air operations. The battle has been referred to as the "typhoon of steel" in reference to the ferocity of the fighting, the intensity of kamikaze attacks, and the sheer number of allied ships and armored vehicles that assaulted the island. In the end the Allies lost more than 65,000 casualties of all kinds.
Cache Specific: You won't be able to drive right up to this one. Feel free to park beside of the road and walk down the trail. The trail won't be visible on Google Maps but I promise it is there. The cache is right off the trail through semi-dense woods. Lots of bug spray is advised.
