This photo apparently only surfaced in 2008. And technically this is apparently on Ie Shima, a small island near Okinawa.
Once the castle had been taken, Dusenberg took off his helmet and removed a flag he had been carrying for just such a special occasion. He raised the flag at the highest point of the castle and let loose with a rebel yell. The flag waving overhead was not the Stars and Stripes, but the Confederate Stars and Bars. Most of the Marines joined in the yell, but a disapproving New Englander supposedly remarked, “What does he want now? Should we sing ‘Dixie?'”
MG Andrew Bruce, the commanding general of the 77th Division, protested to the 10th Army that the Marines had stolen his prize. But LTG Buckner only mildly chided MajGen del Valle saying, “How can I be sore at him? My father fought under that flag!”
LTG Buckner’s father was the Confederate BG Buckner who had surrendered Fort Donelson to then-BG Ulysses S. Grant in 1862.
*Well, if I ever go to war I’ll bring the flag of the US Fish and Wildlife Service. I’ll die waving that flag!
