Between 20 April and 21 April, 300,000 men from the PLA crossed from the north to the south banks of the Yangtze River. Both the Second Fleet of the
Republic of China Navy and the Nationalist fortress in
Jiangyin soon switched sides to the Communists, allowing the PLA to penetrate through Nationalist defenses along the Yangtze. As the PLA began landing on the south side of the Yangtze on 22 April and securing the beachheads, the Nationalist defense lines began to rapidly disintegrate. As Nanjing was now directly threatened, Chiang ordered a
scorched earth policy as the Nationalist forces retreated toward
Hangzhou and Shanghai. The PLA stormed across Jiangsu province, capturing
Danyang,
Changzhou and
Wuxi in the process. As the Nationalist forces continued to retreat, the PLA was able to capture Nanjing by 23 April without encountering much resistance.
Amethyst Incident Meanwhile,
HMS Amethyst of the British
Royal Navy drifted into the fray and was set upon by PLA artillery. She was soon supported by HMSs
London,
Consort and
Black Swan. After a series of artillery duels and negotiations,
Amethyst managed to escape.
Further advance On 27 April, the PLA captured
Suzhou, threatening Shanghai. In the meanwhile, the Communist forces in the west began attacking Nationalist positions in
Nanchang and
Wuhan. By the end of May, Nanchang,
Wuchang,
Hanyang were all under the control of the Communists. The PLA continued to advance across Zhejiang province, and launched the
Shanghai Campaign on 12 May. The city center of Shanghai fell to the Communists on 27 May, and the rest of Zhejiang fell on 2 June, marking the end of the Yangtze River Crossing Campaign. == In popular culture ==
