On February 23, 1942, not long after the outbreak of war in the Pacific, the Japanese submarine I-17 surfaced offshore and lobbed 16 shells at the Ellwood Oil Field, about 10 miles west of Santa Barbara, in the first shelling attack by an enemy power on the continental U.S. since the bombardment of Orleans in World War I. Although the shelling was inaccurate and only caused about $500 damage to a catwalk, panic was immediate.
