Ellis Island
During and immediately following World War II, Ellis Island was used to hold German merchant mariners and "enemy aliens"—Axis nationals detained for fear of spying, sabotage, and other fifth column activity. In December 1941, Ellis Island held 279 Japanese, 248 Germans, and 81 Italians removed from the East Coast. Unlike other wartime immigration detention stations, Ellis Island was designated as a permanent holding facility and was used to hold foreign nationals throughout the war. A total of 7,000 Germans, Italians and Japanese would be ultimately detained at Ellis Island. It was also a processing center for returning sick or wounded U.S. soldiers, and a Coast Guard training base. Ellis Island still managed to process tens of thousands of immigrants per year during this time, but many fewer than the hundreds of thousands per year who arrived before the war. After the war, immigration rapidly returned to earlier levels.
Earl Hancock Ellis
On February 9, 1914, Ellis and the Advance Base Force embarked to New Orleans for a possible deployment to Mexico because of tensions in the area. Barnett was slated to succeed Biddle as commandant, and selected Ellis for special assignment as a member of a Joint Army-Navy Board committee that studied the defenses of Guam and made recommendations for improvements at the outbreak of World War I. Upon arrival on Guam, Ellis was assigned as the committee's secretary and aide-de-camp, and assumed the duties of chief of police, registrar of the civil government, and Intelligence officer. While on Guam, Ellis conducted a simulated attack with a small group of men across the reef at Orote Point, which demonstrated the ability of men in boats to carry out an amphibious attack and capture artillery. Ellis's health began to deteriorate during this assignment, and his medical records attributed his illnesses to alcohol abuse.
