Invasion of Hawaii
It had long been assumed that, if Pearl Harbor was attacked, it would be as part of an attempted invasion of the islands, and that there would be a danger of insurrection by Nisei, Japanese-Americans. Lieutenant-General Walter C. Short (Short, Walter C.) contacted Governor Joseph Poindexter (Poindexter, Joseph) shortly after 1200 to tell him of his fears of invasion and rebellion, and to ask for a declaration of martial law. After the governor had conferred with President Roosevelt the request was granted. Rumour of invasion was rife. The Honolulu Advertiser of 8 December reported in a story headlined "Saboteurs Land Here" that enemy paratroops were on Oahu, red circles on the shoulders indicating their allegiance.
