November, 2004, the remains were disinterred from Greenlawn Cemetery in Pratt and reburied with full military honors at Arlington National Cemetery.interred at Arlington National Cemetery, Section 54 Site 3082. Ellis' maps and papers were confiscated by Japanese authorities. An inquiry undertaken at the behest of General Douglas MacArthur after World War II 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 Caroline islands, noting that they "form a ‘cloud’ of islands stretching east and west.” This cloud concept contrasts with later emphasis on the north to south "Second Island Chain," running from Japan through the Nanpo Shoto and Mariana Islands 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
