In October 1937 Yuan Bao-Kang served in a provisional group consisting of the remnants of 3rd, 4th and 5th PG.

On 12 October the Air Raid Warning Net phoned in a report of two floatplanes flying from Shanghai, apparently on a reconnaissance mission. Colonel Kao Chi-Hang's flight met the two Type 95 floatplanes from the seaplane carrier Kamoi over Chiang-yin. The Chinese Hawk IIIs dived into the attack. Lieutenant Yuan Bao-Kang in No. 2404 got a little too aggressive and collided with one of the floatplanes. The Type 95 crashed in flames but Yuan managed to force land in Chang Chow minus his lower left wing and part of his right upper wing. Yuan suffered only a black eye on landing. The other Type 95 was badly shot up and tried to land on the Yangtse. The Hawk IIIs strafed it until it sank. Both sets of crews, including Lieutenant Commander Nambu, the Squadron Leader, were killed.

Yuan Bao-Kang ended the war with 1 biplane victory this one being claimed while flying Curtiss Hawk IIIs.
