The Japanese carrier fleet tasked with the Pearl Harbor attack turned south after refueling on the previous day, approaching the Hawaii Islands with increased speed. At Pearl Harbor, the American intelligence report on the location of Japanese Navy warships had "no information on submarines or carriers". Elsewhere in Hawaii, Consul-General Nagao Kita received orders to burn code ciphers and important papers; this was noticed by the Americans, who also received intelligence that several Japanese embassies around the world were doing the same.
