@dynastianofficial: On February 25, 1942, just weeks after the United States entered World War II, air raid sirens sounded across Los Angeles following radar contacts and reports of unidentified objects off the coast. The incident, later known as the Battle of Los Angeles, triggered a full military response. U.S. coastal defenses fired over 1,400 anti-aircraft shells into the night sky while powerful searchlights scanned the clouds. Residents watched as explosions illuminated the city, fearing an incoming attack just months after Attack on Pearl Harbor.
