as chief of staff of the
30th Division, but is best remembered for being the last Chief of U.S. Cavalry. In March 1938
Major General Herr was appointed Chief of Cavalry and became a fierce advocate of traditional horse cavalry troops. He defended cavalry as an independent branch of service and opposed conversion of mounted troops into mechanized or armored units. Herr's affection to horse, "somewhat
quixotic" for the period, temporarily made him "a hero and a standard bearer" to generations of officers indoctrinated in cavalry tactics.

, abolished in 1934. His stance towards mechanization, shared by Craig,[Johnson 2003, p. 138.] was based on two assertions: that he will not give away a single man or trade a single horse to the mechanized units, and that the time for mechanization has not come yet.[Johnson 2003, p. 136.] He enforced a formal policy that any increase in mechanized forces must be preceded by a proportional increase in horse cavalry; as a result the 7th Cavalry Brigade remained the only mechanized unit until 1940.[Johnson 2003, p. 137.] Later, he had to admit the rising power of armor, but was just as unwilling to dismount his troops or "give away" officers.
After the outbreak of World War II Herr followed the European campaigns through attaché

Chaffee brought the case to Frank Andrews and then to Marshall, who approved the proposal.

back to horse cavalry and offered him a divisional command but Patton decided that "promotion will be better in the Tanks. I shall probably stay in the tanks."
During the Louisiana maneuvers of 1941 Herr tried to demonstrate the effectiveness of horse cavalry and had a moderate but short-lived success. He still preached that horse can be used en masse, but already realized that cavalry had irreversibly lost its prestige to armor.
Grow wrote that, had Herr supported complete mechanization of cavalry, there would be no independent Armored Forces but a strong, mechanized U. S. Cavalry.[Hofmann 2006, p. 294.] Herr did exactly the opposite; even in 1942 he still struggled for the horse, requesting Marshall for "an immediate increase in horse cavalry."[Winton, Mets 2000, p. 188.] This time Marshall, not constrained by peacetime regulations, chose to dismiss their stubborn chiefs altogether when the offices of the combat arms chiefs were disbanded in a major re-organization streamlining the Army, and their functions transferred to the Army Ground Forces in March 1942. When the office of Chief of Cavalry shut down, Herr admitted that "he had lost it all" and voluntarily resigned.
Retirement
Herr retired to his home in Washington, D.C., which stood just one mile away from the White House, and remained informed of the military politics through correspondence with fellow officers.[ He regularly published his opinion in the press, with the same vigor and affection to the horse. In 1945 Herr wrote that conversion of cavalry to armor was a mistake, an act of "robbing Peter to pay Paul": expansion of armor was necessary, but not at the expense of horse units. He blamed his fall on the alleged conspiracy of General Staff officers seeking promotions in the newly formed Armored Forces. According to Jarymowycz, Herr indeed believed in "betrayal by plotters" like Chaffee.

In 1953 Herr and historian Edward S.
