I. The Siege of Hongdu: Prelude to the Battle of Kanglang Mountain

In 1361 (21st year of the Zhizheng era), Zhu Yuanzhang captured Jiujiang, Nankang, and Jianchang, forcing Chen Youliang to flee to Wuchang. However, Chen, the most powerful warlord at the end of the Yuan Dynasty, did not accept defeat. In April 1363 (23rd year of Zhizheng), Chen launched a massive offensive against Hongdu (modern Nanchang) with a combined land and sea force of 600,000 troops and a fleet of 5,000 giant warships. These ships, several stories high and painted in cinnabar, spanned dozens of miles and were chained together like floating fortresses [1-3].

Zhu Wenzheng, Zhu Yuanzhang’s nephew, held Hongdu with generals Deng Yu and Zhao Desheng. Chen’s army besieged the city for 85 days, using siege towers and battering rams in a relentless multi-pronged assault. With the city’s food and ammunition nearly exhausted, Zhu Wenzheng dispatched Zhang Ziming to slip through the water gates at night. Zhang traveled by small boat for 9 days to reach Nanjing and seek reinforcements. In mid-July 1363, Zhu Yuanzhang personally led a naval force of 200,000 sailors to the Hukou region. The two armies finally met under Kanglang Mountain in Yugan County for the battle that would decide the fate of China. Kanglang Mountain, also known as “Wave-Resisting Mountain,” was famous for its ability to withstand the fierce winds and waves of Poyang Lake, leading to the local proverb: “When sailing on Poyang Lake, let Kangshan be your shore”.

II. Fire on the River: Scortched Waves and Blood-Stained Tides

On July 19, 1363 (23rd year of Zhizheng), the fleets of Zhu and Chen deployed their formations at the foot of Kanglang Mountain. Initially, Zhu’s forces were in a dire position. Chen’s vessels were massive, three-tiered fortresses, while Zhu’s smaller boats struggled to attack from below. Zhu Yuanzhang’s own command ship even ran aground and was nearly captured by Chen’s fierce general, Zhang Dingbian. Only a timely arrow shot by Chang Yuchun saved Zhu from certain death.

The tide turned on the afternoon of July 22. A strong northeastern wind suddenly arose. Zhu Yuanzhang adopted the strategy of his general Guo Xing, deploying a fire-ship suicide squad of 7 light boats filled with reeds, wood, and gunpowder. Driven by the wind, these fire ships crashed into the dense thicket of Chen’s giant warships, creating an inferno that “turned the lake water red and set the sky ablaze”. Chen’s brothers, Youren and Yougui, along with other top officials like Chen Puluo, were burned to death. The Han army suffered staggering casualties, with over 100,000 soldiers killed or drowned, leaving the waters of Poyang Lake red with blood for ten miles. By August 27, with supplies exhausted, Chen Youliang was killed by a stray arrow through his left eye and skull while attempting to break out at Jingjiang Mouth. This 35-day naval engagement remains one of the largest inland naval battles in world military history.

III. Sacrificing for the Lord: Han Cheng and the 36 Loyal Souls

During the most critical moment of the Battle of Kanglang Mountain, the self-sacrifice of Han Cheng became the primary reason for the establishment of the Zhongchen Temple (Temple of Loyal Ministers). Historical records state that when Zhu Yuanzhang’s ship was surrounded and in peril, Han Cheng, who bore a striking resemblance to Zhu, volunteered to die in his lord’s place. Han donned Zhu’s royal robes and jumped into the lake, misleading Chen’s soldiers into believing the King of Wu had committed suicide. This gave Zhu Yuanzhang the precious time needed to retreat and reorganize his counterattack.

In addition to Han Cheng, heroic generals such as Ding Pulang, Yu Tonghai, and Zhang Zhixiong also fell in the line of duty. In April 1364 (24th year of Zhizheng), after his victory, Zhu Yuanzhang ordered the imperial construction of the “Zhongchen Temple” in Yuanjia Village at Kanglang Mountain to honor those who had protected him. The temple was built to worship Han Cheng, Ding Pulang, and a total of 36 generals who were martyred for their lord. The temple faces the lake and is a massive structure, 31 meters wide, 46 meters deep, and 6 meters high. It consists of three halls: the Dingjiang Wang Hall at the front, the Guanyin Hall in the middle, and the 36 Loyalists Hall at the rear.

IV. Through the Centuries: The Destruction and Rebirth of Kangshan Temple

The history of the Zhongchen Temple is an epic of continuous destruction and renewal. Various emperors of the Ming Dynasty ordered multiple renovations. During the Qing Dynasty, in 1666 (5th year of Kangxi), the temple was unfortunately destroyed by a fire. Magistrate Jiang Nanling, out of respect for the ancient heroes, oversaw an extensive reconstruction effort later that same year. By this time, the temple was no longer just an official sacrificial site but a sacred hall for the people of Yugan.

The architectural details of the Kangshan Zhongchen Temple are exquisite. Its gate features an eight-character red stone inscription, guarded by a pair of majestic stone lions that remain well-preserved today. Archaeologists have discovered roof tiles (wadang) and drip tiles (dishui) decorated with “Dragon” and “Phoenix” motifs, signifying the temple’s imperial status. In 1859 (9th year of Xianfeng), to further commemorate historical martyrs, the local government added the “Zhaozhong Shrine” and the “Huaizhong Tower” to the complex. For centuries, the temple has stood as a witness to the rise and fall of dynasties, its incense never dying out thanks to the bustling navigation around Kangshan.

V. Inscribed in Stone: The Collision of Zhu Yuanzhang and Shi Dakai

Among the artifacts remaining at the Zhongchen Temple, the most academically significant is the 1859 Monument of merit for Governor Liu Yangsu in Clearing the River Region. Written and inscribed by Yan Yi, the monument contains exactly 991 characters. Although it was erected by the Qing government to celebrate the suppression of the Taiping Rebellion, the text provides detailed side-notes on the activities of the Taiping Wing King, Shi Dakai, in Jiangxi.

In February 1856 (6th year of Xianfeng), Shi Dakai led hundreds of thousands of Taiping troops through Yugan County on his return to Anqing, his forces stretching for hundreds of miles through places like Shegeng, Jiulong, and Wulei. The Qing government established 19 local militia bureaus in the region to resist the Taiping forces. Paradoxically, the “righteous army” of the Taiping collided with the same waters where Zhu Yuanzhang had his “uprising” five centuries earlier. It is recorded that Shi Dakai once prayed for wind at the Zhang Linggong Temple in Wucheng and, much like Zhu Yuanzhang, supposedly received “the assistance of a divine wind” to win his battle. This merit monument at the Zhongchen Temple serves as a unique physical link between the “Founding Loyalists” of the Ming and the “Taiping Heroes” of the Qing, bridged by the blood-soaked geography of Poyang Lake.
