Pearl Harbor, a deep-water military port nearby Honolulu, Hawaii, was subject to a surprise attack on the morning of December 7, 1941; McClellan AFB was active by 2 pm that day, and hundreds of B-26 Marauders and Curtiss P-40s were being readied for battle, destined for assignment in Alaska. Meanwhile, the city government formulated emergency plans; mayor Thomas Monk increased security around public buildings and kept careful watch over the levees on the Sacramento-San Joaquin Delta. The city's first mandated blackout day was on December 8, although the blackouts over Sacramento were not organized or coordinated well until an ordinance issued by Sacramento County established a system to inform its residents accurately when blackouts would start and end. Rationing and conservation of resources impacted the Sacramentan economy significantly; the federal government confiscated 85% of retail profits for war.
