Great pics, I am not surprised to assume most photos were staged. Just like many yards of US "WW1 footage" actually being filmed by the signal corp after the armistice. That is not to say brave people on all sides have not filmed/photographed during the chaos of battle but what is real/staged and what actually gets saved from the destruction of war is a craps-shoot.
“… corporations have been enthroned, and an era of corruption in high places will follow, … until all wealth is aggregated in a few hands and the Republic is destroyed.”
