On the morning of the 12th, the Japanese air forces received information that fleeing Chinese forces were in the area in ten large steamers and a large number of junks and that they were between upstream from Nanking. While anchored upstream from Nanking, "Panay" and three Standard Oil tankers, "Mei Ping", "Mei An" and "Mei Hsia", came under attack from Japanese naval aircraft. "Panay" was hit by two of the eighteen bombs dropped by three Yokosuka B4Y Type-96 bombers and strafed by nine Nakajima A4N Type-95 fighters.
