Smith was a temporary
colonel when the United States entered
World War II in December 1941. In 1942, promoted to brigadier general, he served as an assistant division commander of the
76th Infantry Division, later becoming a
major general and taking command of the
27th Infantry Division, the unit charged with the defense of the
outer Hawaiian Islands. In November 1943, the 27th Infantry Division was incorporated with the
2nd Marine Division to form the
V Amphibious Corps for the purpose of invading and securing the
Gilbert Islands in the
Central Pacific. While the Marines took the major objective,
Tarawa Atoll (
Operation Galvanic), the Army was tasked with capturing
Makin Atoll (
Operation Kourbash) approx. 120 statute miles to the north. The corps commander,
Marine Corps Lieutenant General Holland M. "Howlin' Mad" Smith, expected the Army's 6,500 men to be able to overwhelm the 800 Japanese defenders in a day. Furious upon being informed of a lack of progress, Holland Smith went to Makin to assess the situation: "When he arrived at Ralph Smith's HQ he was told that there was heavy fighting in progress in the north of the island. Commandeering a jeep, he drove to the scene of the 'battle' and found it, in his words, 'As quiet as Wall Street on a Sunday.'" When Army leaders looked into Holland Smith's claim, they found he was not at the front line, but miles behind it. The "infantry soldiers" that Holland Smith thought he was berating for their complacency were actually supply soldiers offloading cargo. The Marine general then lectured junior Army officers on Makin about the superiority of the Marine Corps over the Army. This incident was the catalyst for a serious breakdown in relations between the Marines and the Army that continued until well after the war." Ralph Smith reported that enemy resistance had been defeated and the island was ready to be turned over to the garrison force four days after the fighting started. In July 1944, the V Amphibious Corps, now including an additional Marine division, was assigned to the invasion of the
Mariana Islands. In this action (
Operation Forager), Ralph Smith's division fought alongside the Marines in the hard struggle for the mountainous island of
Saipan. During the fight for
Mt. Tapotchau in the center of the island, a vast difference in training and tactics between the Marines and the Army led to the
106th Infantry Regiment failing to reduce the area known as "Hell's Pocket," thus falling far behind the advance line of Marines. The corps commander, already ill-disposed toward the 27th Infantry Division because of its perceived lack of aggressiveness on Makin, relieved Ralph Smith of command and ordered him off the island. He contended that Ralph Smith's men had "failed to attack on time," unnecessarily costing Marine lives in the conquest of the island. Five times in the
Pacific Theater of Operations were Army generals relieved of command, but it was unprecedented for the order to be given by a Marine Corps general, and the incident caused a considerable rift between the two branches. The Buckner Board, an all-Army panel that investigated the incident, concluded that, while Holland Smith had the authority to fire Ralph Smith, he had not acquainted himself with the particular difficulties faced by the Army troops in the fight for Mt. Tapotchau and that the firing was "not justified by the facts." Ralph Smith was given command of the
98th Infantry Division charged with the defense of the
Hawaiian Islands, but the negative publicity associated with his firing on Saipan made it impractical for him to remain in the Pacific Theater. He was thus transferred to
Camp Joseph T. Robinson,
Arkansas, where he supervised the
Infantry Replacement Training Center. Smith went on to serve as the
military attaché at the United States Embassy in
Paris and
CARE's chief of mission for France. While he worked for CARE he also oversaw operations in other
western European countries. Smith was decorated with the
Legion of Merit for his service in World War II. Ralph C. Smith retired from the Army in 1948. ==After retirement==
