Huang Gai was a military general who served the warlord Sun family of Eastern Wu for three generations during the late Han Dynasty and Three Kingdoms period of Chinese history. Chen Shou's Records of Three Kingdoms described him as a decent looking man with a more serious appearance.

Huang Gai was born in Quanling County, Lingling Precinct (present-day Yongzhou, Hunan), and first allied himself with Sun Jian during the Yellow Turban Rebellion in the 180s.

At the Battle of Red Cliffs in 208, Huang Gai suggested to Zhou Yu that a fire attack would be the best strategy to use in order to defeat Cao Cao's gigantic fleet and overwhelming numbers. Zhou Yu approved of this method, and Huang Gai sent word to Cao Cao claiming that he wished to defect. Huang Gai had earlier loaded his boats with wax and straw, and when his ships were within proximity of Cao Cao's fleet, he set them ablaze and steered them on a collision course with Cao Cao's lines. This, coupled with the fact that Cao Cao had chained his ships together to prevent their soldiers from being seasick, caused the fire to spread throughout the fleet, causing massive damage and casualties to Cao Cao's army and forcing him into retreat. This plot resulted in a critical victory for both Sun Quan and Liu Bei, who would now be granted more than enough time to rally their armies and further bolster their positions within their respective territories. During the battle, Huang Gai was hit by an arrow and fell from his boat, but was rescued by Han Dang. He is said to have been highly praised and deeply trusted amongst his colleagues, particularly his third lord, Sun Quan. Huang Gai received various titles throughout the years, including: Auxiliary Corps Commander, Acting Colonel of the Firm Attack, Chief Commandant of Danyang, General of the Gentlemen of the Household, and Governor of Wuling.

Sun Quan (182–252), formally Emperor Da of Wu, was the founder of Eastern Wu during the Three Kingdoms period of Chinese history. He ruled from 222 to 229 as King of Wu and from 229 to 252 as Emperor of Wu.

In his youth, Sun Quan spent time in his home county of Fuchun, and after the death of his father Sun Jian in the early 190s, at various cities on the lower Yangtze River. His older brother Sun Ce carved out a warlord state in the region, based on his own followers and a number of local clan allegiances. When Sun Ce was assassinated by the retainers of Xu Gong in 200, the eighteen-year-old Sun Quan inherited the lands southeast of the Yangtze River from his brother. His administration proved to be relatively stable in those early years. Sun Jian and Sun Ce's most senior officers, such as Zhou Yu, Zhang Zhao, Zhang Hong, and Cheng Pu remained loyal; in fact it was mentioned in Romance of the Three Kingdoms that Sun Ce had at his deathbed reminded Sun Quan that "in internal matters, consult Zhang Zhao, in external matters, consult Zhou Yu." Thus throughout the 200s, Sun Quan, under the tutelage of his able advisors, continued to build up his strength along the Yangtze River. In early 207, his forces finally won complete victory over Huang Zu, a military leader under Liu Biao, who dominated the middle Yangtze.

Liu Biao (142 - August 208), style name Jingsheng (景升), was a warlord and the governor of Jing Province during the late Han Dynasty. He was a member of the extended family of the Han emperors. He was good-looking and his height was said to have been over eight chi (about 1.86 m).^{[citation needed]}

When the Han Dynasty was consumed with war following the Yellow Turban Rebellion, Liu Biao held the title of governor of Jing Province. Liu Biao later started a war against the warlord Yuan Shu and his minor warlord vassal, Sun Jian. During the Battle of Xiangyang Sun Jian was put in command of an army on Yuan Shu's orders to assault Liu Biao in Jing Province. Liu Biao appointed Huang Zu to command the forces against Sun Jian. During the battle, one of Liu Biao's strategists, Kuai Liang, devised a plan to eliminate Sun Jian by crushing him with logs as he rode towards the main camp of Liu Biao's camp^{[citation needed]}, and succeeded. Years after, Sun Jian's two eldest sons, Sun Ce and Sun Quan, caused Liu Biao no end of trouble as they sought to avenge their father's death. However, they did not cause Liu Biao's demise as they targeted Huang Zu, who was a general under Liu Biao, instead of Liu Biao himself. Whilst Cao Cao (in the north) was gaining strength, Liu Biao chose to neither help nor hinder his conquests, in part because he had been dealt a defeat against the forces of Sun Ce at the Battle of Shaxian.
