It is particularly interesting to record that, in the course of this summer and autumn, a Regiment of Yorkshire Yeomanry met their friends of the 49th Division in and about the defences of Thiepval. We shall come, in Chapter XIV below, to the experiences of the Mounted Troops who left the West Riding for France during 1915. There we shall see how they served as Divisional Cavalry for several months, and how, in May, 1916, they were re-organized as Corps Cavalry, and were set to do various duties, not always appropriate to their Arm, which they discharged with a thoroughness and an efficiency worthy of the best traditions of the Service. The Yorkshire Dragoons were posted to the IInd Corps, which, on July 25th, 1916, took over that sector of the Fifth Army front which lay between Ovillers-la-Boisselle and Thiepval. The hopes of a Cavalry situation, unfortunately, never materialized, but the Dragoons did excellent work during the Battle of the Somme by maintaining Observation Posts in forward areas, thus short-circuiting the means of communication between Corps Headquarters and Battalion Commanders. ‘During operations,’ we are told, ‘information received in this way and from other sources was embodied each day in maps and reports, which were sent up by despatch rider during the night, and reached front line units in time for the usual attack at dawn.... The observers were sometimes asked to undertake special work of great importance. Before several attacks they were required to reconnoitre and map the enemy’s wire. The slightest mistake might have lost hundreds of lives, but it was never made.’ Among the names which we may mention _honoris causa_ in connection with this service are those of Captain, later Major, R. Brooke; Major, later Lieut.-Col., R. Thompson; Sergts. Storer and Tinker (Military Medals), and Corpl., later Sergt., Cranswick (Bar to M.M.). Let us consult the map once more.
