From the 2nd to the 10th of October, 1918, near Blanc Mont, Lieutenant Colonel Ellis has shown a high sense of duty. Thanks to his intelligence, his courage and high energy, the operations that this Brigade ( Fourth Brigade, Second Division) took part in, have always been successful.


Post-World War I

The war ended on November 11, 1918. On November 17, the 2nd Division marched north to begin occupation duty. For the remainder of the occupation, the 4th Marine Brigade was employed along the Rhine. When the 5th Regiment's commander, Logan Feland was promoted to brigadier general, Colonel Harold Snyder assumed command of the regiment, and Ellis was appointed as regimental

The effect of his llis'sthorough knowledge of intelligence duties and of his hard work in training his subordinates became apparent almost at once. The intelligence reports, which had been a mass of unrelated and generally unimportant scraps of information, became well-compiled and well-digested reports of the condition in Santo Domingo.

, and Palau Islands, which flanked the U.S. lines of communications in the region by more than 2,300 miles. Ellis's Operation Plan 712 predicted that Japan would initiate a war, and that Japan would stay near their own territorial waters until encountered by the U.S. fleet. He also added that great losses would occur in what he termed the "ship-shore belt" because of confusion during amphibious assaults. Ellis advised war planners to minimize confusion and casualties by organizing task forces prior to leaving base ports, and to maintain unit integrity rather than dividing Marines up among several transports.
... a major fleet action would decide the war in the Pacific; the U.S. fleet would be 25 percent superior to that of the enemy; the enemy would hold his main fleet within his defense line; fleet units must be husbanded; preliminary activities of the U.S fleet must be accomplished with a minimum of assets; Marine Corps forces must be self-sustaining; long, drawn-out operations must be avoided to afford the greatest protection to the fleet; sea objectives must include a fleet anchorage.

Ellis believed that US acquiescence to Japan's

, which allowed Japan to occupy islands that had previously been controlled by Germany, would enable Japan to operate behind a defensive screen to expand its territory and influence without being observed. Convinced that this course would eventually lead to war between Japan and the United States, Ellis determined to carry out intelligence gathering activities to obtain details on Japan's activities. On April 9, 1921, Ellis submitted a pro forma request to the commandant to conduct a clandestine reconnaissance mission to the Central Pacific to examine the Marshall and Caroline Islands. His request indicated that he expected to travel as a civilian and to provide an undated resignation that would enable the Marine Corps to deny knowledge of his actions if necessary. (In fact, the Marine Corps did not use the letter of resignation, and retained Ellis on its roll of active officers until he died. At the time of his death, Ellis was listed in payroll and personnel records as being on "extended leave," a status the commandant had directed his staff to use.) Shortly after he submitted his request he suffered another occurrence of

to finish making arrangements. To hide his identity as a military officer gathering intelligence abroad, Ellis turned to John A. Hughes, who was commissioned from the ranks with him in 1902. Hughes had been medically retired in 1920, after which he joined his father's import-export business, the Hughes Trading Company. Hughes provided Ellis with a cover identity as a traveling representative of the company. After a brief visit home to Kansas, Ellis traveled to San Francisco on May 28, 1921. He subsequently traveled to New Zealand and Australia via the

was able to track his whereabouts by his withdrawals from the special bank account they established to fund his covert activities. As Ellis continued his intelligence gathering mission and heavy drinking, he attracted the attention of the Japanese authorities, who began to keep track of his movements and activities. A friend, Kilili Sablan, suggested that Ellis check out of the hotel and live with the Sablan family. Ellis traveled around Saipan for several weeks, and produced detailed maps and charts.

, he met a teenage Palauan woman named Metauie, who became his wife. His friends attempted to keep him from drinking, but by then, he had a coterie of native boys who would obtain his alcohol for him. He continued to drink excessively, and his health continued to deteriorate. On May 12, 1923, he was unable to obtain any alcoholic beverages as the result of his friends attempting to keep him sober, and he unsuccessfully looted the home of his friend William Gibbons in search of drink. Aware of Ellis's condition, the Japanese police had two bottles of whiskey delivered to him; he consumed them both, and died later the same day from the effects of excessive alcohol intake.

found no trace of any of Ellis' effects, nor a report on Ellis' activities by the Japanese governor of the island. It is not clear how competently Ellis performed his map-making and analysis, given his demonstrated instability in the final months of his life and the fact that the Japanese had not yet begun fortifying Palau. Had Ellis survived, he would likely have completed addenda to "Advanced Base Operations in Micronesia" that would have provided military authorities with information on the potential military uses of the islands.


Legacy

Though he had a native wife in Papua, Ellis was not married before traveling in the Pacific islands, and he had no children. Ellis had a Marine Corps-wide reputation for excellence in organizational, administrative, intelligence analysis, and strategic planning, as evidenced by the fact that successive Commandants, including Biddle, Barnett, and Lejeune, relied on Ellis for their most important activities, including covert information gathering, despite being aware that he consumed alcohol so excessively that he often required a doctor's care and extensive hospitalization before he could return to duty. Despite the loss of the maps and notes from his final intelligence gathering effort, Ellis' overall strategic view of the Pacific Ocean islands remained valid, especially in light of events at the start of US involvement in World War II. In ''Operations Plan 712: Advanced Base Operations in Micronesia''
drew particular attention to the strategic value of the Marshall and

to Indonesia.
In addition to predicting the circumstances of World War II in the Pacific, Ellis is regarded as a significant strategic theorist in the history of the Marine Corps because his advocacy of amphibious warfare aided the Marines to identify and organize for an enduring mission, which replaced what had previously been their primary function—small security detachments on ships and at naval bases. Ellis is listed on the Roll of Honor of the Marine Corps Intelligence Association, which lists Marines from the Intelligence field who were killed in the line of duty. Ellis Hall, one of the main educational buildings at the Marine Corps' Quantico base, is named for Ellis.
