Following their wedding, Lieutenant and Mrs. Tolkien took up lodgings near the training camp. On 2 June 1916, Tolkien received a telegram summoning him to Folkestone for posting to France. The Tolkiens spent the night before his departure in a room at the Plough & Harrow Hotel in Edgbaston, Birmingham.
