 The confined space of the anchorage severely limited the maneuverability of the nationalist warships for fearing collision in the darkness, and the communist gunboat was able to utilizing the blind spots of the larger nationalist naval guns by fighting at extremely close quarter when engaging the larger nationalist ships after sinking a nationalist gunboat.In the meantime, two other communist gunboats, "Vanguard" and "Struggle", managed to sink two nationalist gunboats east of Ox Head (Niutou, 牛头) Island, while two battalions of the communist landing force took Green Islet (Qing Zhou,青洲) and Triangle (Sanjiao, 三角) Island.After the sunrise, the nationalist fleet discovered that there was only a single small communist gunboat fighting them, and as the enraged nationalist sailors attempted to avenge the deaths of their comrades-in-arms, every nationalist naval vessel available joined the chase of the communist 25-ton gunboat "Liberation".
