On 14 November 1965 at around 12:30 am, a PT boat reached within four cable lengths of Lin Huai and fired two torpedoes within 300 meters (330 yd).

At 1:40 a.m, it reached the Wuqiu anchorage where it managed to repel all further attacks until 4:28 a.m when dawn arrived and the PLAN forces retreated.

Mai and Chen who were responsible for carrying out the mission returned to Zuoying District where Chiang Ching-kuo ordered that they be detained and handed over to the Military Justice Bureau of the Ministry of National Defense to stand trial.
