National Army troops at the South Western Front during the Irish Civil War.
We've discovered (mostly through all of your efforts here on Flickr) that some of our W.D. Hogan collection dates are not as secure as we thought, so thanks to sbreathnach
for giving us a location for this one at the Ordnance Barracks, Mulgrave Street, Limerick and a date of Friday 21st or Saturday 22nd July 1922!
Date: Friday 21 or Saturday, 22 July 1922
