I wonder if anyone can understand the reason the firm I bought a copy of my father's medal card would write "5a (Asia) = Hejaz" on the back? The Hejaz or Hijaz is a long way from Mesopotamia, where I believed he served. He was with 'S' Battery Royal Horse Artillery attached to 6 Indian Cavalry Brigade. He did mention that his unit was involved with T E Lawrence, but I later assumed that this was because Lawrence had visited Mesopotamia. His medal card notes his date of entry into the theatre of war as 23-2-15, is it possible that some of the British forces arrived in the Hejaz? Thanks, John Guy
