charles kavanagh had complained that the household cavalry regiment used up "a large number of horses" and are "not getting as good officers as the others." humphrey wyndham, who was with life guards, told churchill that his preference was for household cavalry to become tank and not machine guns. "then the life guards and blues would have led the way in the mechanization of the cavalry, instead of being made to follow it." as it was they mobilized their horses in 1939; four of the officers in the blues at that time were masters of fox hound. wyndham went on: "the horse, after serving as a medium of mobility in war from the earliest times, was in process of supersession by the internal combustion engine across the valley."
