北洋水師
In the years leading up to the First Sino-Japanese War in 1894, Liu repeatedly pressed Li Hongzhang to develop the Beiyang Fleet. He pointed out that Japan was enthusiastically expanding its navy, and to keep up the Beiyang Fleet must adopt an annual program to add new ships. However, Li Hongzhang was unable to expand the Beiyang Fleet due to the realities of court politics. The First Sino-Japanese War began in 1894, and on 17 September of that year, the Beiyang Fleet encountered the Japanese Combined Fleet on the Yellow Sea, sparking the Battle of the Yalu River.
