The first aerial bombing of the American continent during World War II took place on 3 and 4 June 1942, when two Japanese raids were made on the Dutch Harbor in the city of Unalaska, Alaska. While the first did little damage, the second destroyed the base's oil storage tanks, part of the hospital, and damaged a beached barracks ship. Although American pilots had finally located the Japanese carriers, attempts to destroy them proved fruitless. As bad weather again set in, all contact with the enemy fleet was lost.
