Figures 17 and 18: Postcard of a group of King Edward's Horse at Garston, Watford on 14 December 1914. The sender of the card is John Callum Newlans Eastick and he wrote on the back of the card that he wasn't actually in the postcard as these were Troopers of 'C' Squadron who had among their ranks many former members of the original Cambridge and Oxford university troops of the King Edward's Horse. He also notes that all leave had been cancelled and he thinks it unlikely he will be home for Christmas.
‘C’ Squadron (Australasian) together with Regimental HQ landed at Havre on 22nd April 1915 and joined 47th (London) Division and then joined IV Corps Cavalry Regiment on 1st June 1916
