Mortimer Hogan was my father. He worked with shoeing horses in the army. His regiment was S. Irish Horse. He was underage when he joined up - he siad he was a year older than he was. He had been working on the railway but left to join the army and "see the world" or "see the next world". He was gassed and invalided in 1917. He did not speak much about it but said the he was in the trenches in "rivers of blood". He worked with horses also.
