楊諒
In 598, King Yeongyang of Goguryeo attacked Ying Province, and while the governor of Ying Province, Wei Chong (), fought off the Goguryeo attack, Emperor Wen was angered. He sent his son Yang Liang the Prince of Han and Wang Shiji to serve as commanding generals, with Gao Jiong serving as Yang Liang's assistant, and the former Chen general Zhou Luohou () serving as the commander of the navy, to attack Goguryeo. However, the forces ran into food supply problems, and the ships ran into a storm and suffered great losses. Both at sea and on the ground, Goguryeo forces inflicted heavy losses on the Sui forces. Nevertheless, King Yeongyang ceased his raids into China and so Emperor Wen called off the campaign against Goguryeo, unable to commit yet another enormous force to punish Goguryeo after the recent losses. As King Wideok of Baekje offered assistance to Sui during the campaign, this precipitated a conflict between Goguryeo and Baekje.
