The attack continues until 1554 when USS PANAY sinks. Three men are killed and 43 sailors and five passengers are wounded. Two of the three oil barges are also bombed and destroyed.
Tokyo. American Ambassador Joseph C. Grew immediately lodges a formal protest. The Japanese government accepts responsibility, but claims the attack was unintentional.
Washington, DC. The militarily unprepared United States government is anxious to avoid war. The Roosevelt Administration accepts the "mistake" theory, together with an indemnity of $2.2 million paid in April 1938, and the incident is officially settled.
KAMOI launches a flight of E8N2 floatplanes to attack Canton (Guangzhou). One E8N2 shoots down a Chinese scout plane over the city. The next day, four E8N2s encounter a lone, but powerful, Gloster Gladiator of the Chinese Air Force being flown by a British pilot. In a 10-minute dog fight, the Englishman holds off his attackers.

Christie (USNA '35) aboard for a "familiarization" war patrol, spots KAMOI and an escort. Griffith tracks KAMOI all day, but is forced to dive five times by her seaplane air cover.
At about 2100, running on the surface, Griffith fires six bow torpedoes at KAMOI in a radar attack, but she zigs and they all miss. The escort's crew does not see USS BOWFIN, but starts dropping depth charges. Griffith moves off to reload.
At 2200, USS BOWFIN makes another surface attack with six torpedoes. Two torpedoes hit KAMOI below the bridge. Griffith closes the range on the surface, but suddenly KAMOI opens fire at USS BOWFIN with her two 4-inch deck guns and machine-guns. Griffith zigzags away at high speed, but remains on the surface.
