 When a major damage occurred, tugs were needed to tow the damaged vessel, and in the event of war when tugs could not be available, the damaged vessels had to be abandoned.In contrast, the communists had comprehensive facilities and infrastructures on the mainland and since the archipelago at the communist's doorstep, they could simply recover the abandoned nationalist vessels and repair them after taking them back to the mainland, and put them back into service to fight against the former owners of these vessels, as the case of the eleven naval vessels abandoned by the nationalists after the battle.As for the blockade of the mouth of the Pearl River, it certainly caused difficulties for the communists.
