The Vietnamese during Lý dynasty had one major war with Song China, and a few invasive campaigns against neighboring Champa in the south.^[138] The most notable conflict took place on Chinese territory Guangxi in late 1075. Upon learning that a Song invasion was imminent, the Vietnamese army under the command of Lý Thường Kiệt, and Tông Đản used amphibious operations to preemptively destroy three Song military installations at Yongzhou, Qinzhou, and Lianzhou in present-day Guangdong and Guangxi. The Song dynasty took revenge and invaded Đại Việt in 1076, but the Song troops were held back at the Battle of Như Nguyệt River commonly known as the Cầu river, now in Bắc Ninh province about 40 km from the current capital, Hanoi. Neither side was able to force a victory, so the Vietnamese court proposed a truce, which the Song emperor accepted.^[139]
