Nice to hear from you so soon. I do have names on the back the postcard, although not full names, and two are difficult to read. I will add the images for you now in my photos.
Hi Josephine, I have a postcard photo including Herbert Bolt, my great grandfather Francis Johnston and four other soldiers. Frank was with Herb when he died and was the one who recounted his last moments. You may already have the photo but if you like I will add it to the site.
