Looking at the occupants of a single house can open up much wider events in the past - it's micro personalised history with which we can identify.  During the First World War a resident of a Connaught Square house I am researching travelled continuously on behalf of the Army Remount Service to buy horses as remounts in the USA, Canada, Australia and New Zealand.  These buyers had to have a good deal of equine experience so as not to be conned into buying 'duds'.  3 million horses were engaged in the war by 1915; however it was estimated that the average life of a horse on the firing line in Belgium and France was about ten days.  Artist A.J. Munnings was also involved with the Army Remount Service, at first processing tens of thousands of Canadian horses en route to France.  Later he was assigned to one of the remount depots on the Western Front.
