Although Japanese officials maintained that their pilots never saw any American flags on "Panay", a US Navy court of inquiry determined that several US flags were clearly visible on the vessel during the attacks. At the meeting held at the American embassy in Tokyo on December 23, Japanese officials maintained that one navy airplane had attacked a boat by machine gun for a short period of time and that Japanese army motor boats or launches attack the Chinese steamers escaping upstream on the opposite bank. However, the Japanese navy insisted that the attack had been unintentional. The Japanese government paid an indemnity of $2,214,007.36 to the US on April 22, 1938, officially settling the "Panay" incident.
