Jack Hollyhead, my grandfather, sent various postcards home to Annie ("Nance") while he was serving in France, first in the Coldstream Guards, and then in the Royal Flying Corps. He and Annie got married at Malvern Priory on September 13th 1915, shortly after which he returned to the front. He was certainly back by September 26th because there is a card addressed to Dearest Wife bearing that date. The messages on the cards were subject to military censorship, so they contain very little information about his activities.
