That ride into the blue did not encourage the cavalry to the belief that they would be of real value in a warfare of trench lines and barbed wire, but for a long time later they were kept moving backward and forward between the edge of the battlefields and the back areas, to the great incumbrance of the roads, until they were “guyed” by the infantry, and irritable, so their officers told me, to the verge of mutiny. Their irritability was cured by dismounting them for a turn in the trenches, and I came across the Household Cavalry digging by the Coniston Steps, this side of Thièpval, and cursing their spadework.
