Shortly after sunset on February 23, 1942, the Japanese submarine I-17 surfaced and positioned itself near Ellwood, California. The submarine was armed with a single deck gun, which was loaded and aimed. The target was an aviation fuel tank on the shore. However, due to rough seas and a dark night, the Japanese captain had little hope that his explosive shells would cause enough damage to ignite the fuel tank. He was right. Most of the shells fell harmlessly and caused minor damage. But I-17’s goal was not destruction but terror, and in that, it was highly successful.

Panic quickly spread through the Los Angeles region. Civilians were terrified that the shelling was the precursor to an invasion of the West Coast by Japanese forces. Soon, jumpy people began to spot Japanese cruisers off the coast in the gloom, and everyone began watching the skies with trepidation. There was no imminent Japanese invasion. The Japanese forces were thousands of miles away in Southeast Asia and the Central Pacific, but that didn’t help assuage the fears of the population, who were convinced that they were about to be targeted, similar to Pearl Harbor barely two months earlier.

This cloud of fear is what caused the Battle of Los Angeles the following day.
