In the spring of 1895, the Revive China Society, which was based in Hong Kong, planned the First Guangzhou Uprising. Lu Haodong was tasked with designing the revolutionaries' Blue Sky with a White Sun flag.
The Chinese fleet subsequently retreated behind the Weihaiwei fortifications. However, they were then surprised by Japanese ground forces, who outflanked the harbour's defenses in coordination with the navy. The Battle of Weihaiwei was a 23-day siege with the major land and naval components taking place between 20 January and 12 February 1895. Historian Jonathan Spence notes that "the Chinese admiral retired his fleet behind a protective curtain of contact mines and took no further part in the fighting." The Japanese commander marched his forces over the Shandong peninsula and reached the landward side of Weihaiwei, were the siege was eventually successful for the Japanese.
After Weihaiwei's fall on 12 February 1895, and an easing of harsh winter conditions, Japanese troops pressed further into southern Manchuria and northern China. By March 1895 the Japanese had fortified posts that commanded the sea approaches to Beijing. Although this would be the last major battle fought; numerous skirmishes would follow. The Battle of Yinkou was fought outside the port town of Yingkou, Manchuria, on 5 March 1895.
In the wars against the Taiping (1851–64), Nian (1851–68), Yunnan (1856–68) and the Northwest (1862–77), the traditional imperial troops proved themselves incompetent and the court came to rely on local armies. In 1895, China suffered another defeat during the First Sino-Japanese War. This demonstrated that traditional Chinese feudal society also needed to be modernized if the technological and commercial advancements were to succeed.
On 26 October 1895, Yeung Ku-wan and Sun Yat-sen led Zheng Shiliang and Lu Haodong to Guangzhou, preparing to capture Guangzhou in one strike. However, the details of their plans were leaked to the Qing government. The government began to arrest revolutionaries, including Lu Haodong, who was later executed. The first Guangzhou uprising was a failure.
