“The old cavalry units had been converted variously into infantry or artillery or armor or reconnaissance units, plus one vestigial type that lingered briefly; this was a ‘horse-portee’ unit, in which the horses were bodily transported in motor vans for the long road hauls and then unloaded for use in local reconnaissance. This device, totally abandoned in February of 1942 as fantastic, was the last effective struggle made by the American cavalryman in behalf of his horse’s place in the overseas combat forces. For decades the mounted service had been the mainstay of frontier fighting and the school in which some of the Army’s most distinguished and aggressive field commanders both in World War I and World War II had received their tactical training; the horse cavalry now was finished as a major arm.” – Mark Skinner Watson, Chief of Staff: Prewar Plans and Preparations, Vol. 1-1, United States Army in World War II
