Thank you very much for the photos. I just want to add a couple of comments.
Among the photos you provided
@NebrHogger there are two that are clearly modern reconstructions and not historical photographs from the Spanish Civil War (1936-1939).
These are:
In both cases, the comments in the captions are incorrect, as both photos come from a set of photographs of a modern re-enactment of the Battle of the Ebro taken by photographer Xavi Calzada.
I am not entirely sure of the date, but I suspect that they probably come from the famous reconstruction that has been carried out annually since the mid-2000s by the Fayón Town Council (Aragon) and the Fayón Volunteer Group. And specifically, given the time of creation and publication of some of the images in the photographic work, I would say that they are most likely from the 2007 or 2008 re-enactments.
Xavi Calzada published an extensive online photo work that includes the second image (Page 15) and a close-up of the first one (Page 31) several years ago. Here is the link:
