Odo Vivian, the 3rd Lord Swansea (1875-1934) served as a Lieutenant-Colonel in the Glamorgan Yeomanry. He wrote several hundred letters to his wife between February 1917, when he went to the front, and January 1919. For reasons of security and a probable desire not to cause alarm, they do not to reveal much about military action, but give a strong indication of the brave face and good humour that soldiers must have felt obliged to show to their loved ones.
There is a large collection of letters from Lord Swansea which are all now in the archive. In due course all will be transcribed to share his unique view of World War One but for now we have 4 letters transcribed and the remainder of Lord Swansea's diary from February to May 1917 as scanned copies which you can read by clicking and enlarging each small page below.
