The last I have heard the area has not changed much. There is a Veteran of the battle in my area. I met him during a fund raising event for a Korean War Memorial locally.
He attended the 60th anniversary event sponsored by the US Army there in 2011. He had multiple photos of the area and he said that it “hadn’t changed a bit.” He is a neat man to talk too. From what I can recall of our conversation, he really thought he was going to die there when they were told to dig in. However he said they had the time to prepare and they were ready. As a result of that preparedness, he said casualties in his company were rather light. However they expanded a great deal of ammunition and made it a bad day for a lot of “china men. “
That is about all I really know of the battle.
Scout - You have a heritage to be proud of. I can also tell you that there is a certain feeling you get when you walk a battlefield that your Grandfather fought on. It is rather indescribable. I can recall when I first arrived on Okinawa in 1977, 42 years after my Grandfather had fought there, how amazed I was to see the grounds he help take. There is a personal connection to it. At first, I wanted to explore every bit of the ground and I did. Knowing from our conversations, I knew where his unit was and I used to picture him being “right there.” After a while, it became very emotional. Especially after I met some Okinawans who had survived and listened to their stories about the carnage and bloodshed, it was then that I became very grateful that he was able to share his thoughts and how lucky I was to still have him.
