On May 28, 1950, the nationalist naval force at the region was reinforced by 3 frigates, 2 landing ships, 4 minesweepers, and several gunboats newly arrived from Taiwan. The nationalist naval force cruised in waters north of Little Green Islet (Xiaoqingzhou, 小青洲) and Ox Head (Niutou, 牛头) island, attempted to bombard the communist positions on lands and the transport fleet. As the communist gunboats came out to meet them, the nationalist force still weary of previous naval engagement three days ago withdrew to open ocean, where the conditions favored the larger nationalist fleet because there was more space to maneuver. However, the communist gunboats did not pursue because the communists were fully aware their meek naval strength and once the mission of preventing the nationalist naval fleet from bombarding the communist assets was completed, the communists gunboats withdrew.
