Extent of Martial Law, 1941

From Ghosts of Honolulu: A Japanese Spy, A Japanese American Spy Hunter, and the Untold Story of Pearl Harbor, by Mark Harmon and Leon Carroll, Jr. (Harper Select, 2023), Kindle pp. 126-129:

Lt. Col. Thomas Green, now the Hawaiian Department’s judge advocate, moves into Iolani Palace the day after Pearl Harbor. The man who wrote the rules governing the military administration is on hand to direct martial law operations.

At 12:30 P.M., Green switches on the radio to hear President Roosevelt address a joint session of Congress....

Green switches the radio off. The reality of his position washes over him like a wave—with the war official, the martial law over Hawaii is good as permanent. Now the Army must run everything. All civilians need to be registered and fingerprinted. Manpower is needed to censor the press, long-distance telephone calls and all civilian mail. The Army must police the ban on liquor sales. The list seems endless.

Emergency medical facilities fall under direct Army control. That includes the Japanese Charity Hospital—the military took control of over half of the hospital’s facilities in the aftermath of the attack. The day before, eight hundred volunteers from the United Japanese Society in Honolulu, freshly trained to respond to medical emergencies, went straight from their graduation ceremony to tend to the wounded.

Of all the challenges Green faces, creating a functioning justice system is the thorniest. It’s not easy to replace the civil system with military courts overnight. Easing his job is the lack of impediments: the writ of habeas corpus remains suspended, search warrants are unneeded and even written charges are optional. Being tried before a military court will be a shadow of the former process—presided over by a sole officer, who’ll be encouraged to sentence offenders the same day of their arrest.

Japanese Hawaiians are subject to special restrictions. For them, meeting in groups of more than ten is forbidden. Being outside during the nightly blackouts is cause for detention. The entire community is ordered to turn in all firearms, flashlights, portable radios and cameras.

At his home on Kalama Beach, Otto Kuehn hears the rap on his front door, blood frozen. The military police hustle him, Friedel, Hans Joachim and Susie into a truck. All are held in cells at the US Immigration Service’s detention center in Honolulu, held for the crime of being German in Hawaii.
