Are those Confederate soldiers in the U.S. civil war?
I bet the first one is in Gettysburg, PA.
I don’t know about the second one but the third one is Richmond, VA (2nd Confederate capital) burned out.
It's Hiroshima. AFTER.
The second one is probably of Japanese on some Pacific island. I'd guess Tarawa, but it could be anything from Guadalcanal to Iwo Jima. The pathname has something about USMC in it.
I can't access the first one, something about it being gross and indecent. :)
