Why Were Li Hongzhang's Telegrams Deciphered by Japan? Re-examining the Sino-Japanese War of 1894-1895 from a Geopolitical Perspective

原文:李鸿章电报为何被日本破译?从地缘政治角度再看甲午战争

Summary of Key Points

This report uses the "Haiyan" ship as a historical thread to connect the pinnacle moment of Li Hongzhang's final inspection of the Beiyang Fleet in 1894, the outbreak of the Sino-Japanese War of 1894-1895, and the collapse of the Beiyang Fleet, as well as scholar Sha Qingqing's interpretation of the deeper underlying causes of the war. These include Japan's long-term intelligence infiltration, the power struggles among international forces, and the fatal flaws in the Qing Dynasty's system. Ultimately, it reveals how the Sino-Japanese War altered the geopolitical landscape of East Asia and continues to have repercussions today. The "Haiyan" ship, which went from being a majestic inspection vessel to a humiliating bargaining vessel, and then to a tragic self-sinking act to block the river channel, has become a vivid metaphor in modern Chinese history.

Analysis in Detail

1. The Fate of the "Haiyan" Ship: A Microcosm of Modern History

The "Haiyan" was no ordinary ship. In May 1894, it carried Li Hongzhang to inspect the Beiyang Fleet, which was then the strongest naval force in Asia, marking a glorious moment for the Qing Navy. Ten months later, it was renamed "Gongyi" (to avoid being seized by the Japanese and flew the German flag) and used to transport Li Hongzhang to Shimonoseki, Japan, to sign an unequal treaty. After the war, it was purchased by the China Merchants Steam Navigation Company and used as a passenger and cargo ship. In 1937, it sank during the Battle of Shanghai, using its own hull to block the Yangtze River channel and prevent the Japanese from advancing upstream.

Sha Qingqing describes it as a "metaphor for modern history," as it witnessed the efforts of the Self-Strengthening Movement (the rise of the Beiyang Fleet), the devastating defeat in the war, and the nation's struggle (its self-sacrifice through sinking). It reflects the rise and fall of the Qing Dynasty like a mirror.

2. Japan's Intelligence Warfare: Why Were Li Hongzhang's Telegrams Deciphered So Easily?

During the Sino-Japanese War, all of Li Hongzhang's encrypted telegrams were decrypted by Japan. Why was this possible?

  • Weak Qing Cryptography: The "Mi Hong" system used a numerical codebook, which was vulnerable to theft by spies, essentially like losing the keys to one's home.
  • Japan's Preparatory Actions: Since the 1870s, Japan had identified the Qing Dynasty as a potential enemy and sent spies to gather information in China—about the locations of fortifications, port depths, city layouts, and even the personal relationships of officials.
  • Poor Qing Security: The codebooks were updated infrequently, and key management was chaotic, allowing spies to penetrate various levels of government (even Zhang Zhidong, the Governor-General of Huguang, was unable to stop them). As a result, Li Hongzhang was completely unaware of the Japanese troop landings in Korea and could only rely on foreign newspapers for news. The front lines often reported only good news, leaving him without real insight into the battle situation.

3. International Power Struggles: Why Did Britain, America, and Russia Stand By While China Was Attacked?

Why did Li Hongzhang's requests for mediation from Britain, America, and Russia go unheeded?

  • Britain's Self-Interests: At that time, Russia was building the Trans-Siberian Railway, and Britain feared that Russia would claim territory in the Far East. Japan offered to help contain Russia, so Britain acquiesced to Japan's war efforts (even maintaining neutrality during the Anglo-Japanese Treaty negotiations).
  • Russia's Priorities: Russia was preoccupied with its railway construction and had no interest in intervening in East Asia for the time being.
  • China's Outdated Diplomacy: The Qing diplomats in Britain did not speak English, and decisions relied on interpreters. Li Hongzhang's strategy of using foreigners to counter foreigners was merely an illusion; he failed to understand the core interests of the great powers (for example, Britain's main concern was its own territories, not the fate of the Qing Dynasty).

Sha Qingqing points out that without the competition among these powers, the war might not have occurred in 1894. Japan exploited a gap in the international situation.

4. The Fatal Flaws in the System: Was the Sino-Japanese War Really "Li Hongzhang's Alone Battle?"

There is a notion that the Sino-Japanese War was entirely Li Hongzhang's responsibility. Why?

  • Internal Divisions within the Court: Emperor Guangxu wanted to use the war to establish his authority, but officials like Weng Tonghe lacked military expertise. Empress Dowager Cixi held ultimate power but was unwilling to fully support him, fearing it would disrupt her birthday celebrations.
  • Mismatch of Powers: Although Li Hongzhang held the title of "Prime Minister," he lacked the authority to coordinate national resources and supplies—logistics had to be managed on his own (for instance, Zuo Zongtang had to rely on Hu Xueyan for funding during his campaign in Xinjiang). There was no unified national coordination system.
  • Inherent Problems with the Army: The Qing military had a habit of reporting only good news; for example, they claimed victory despite losing the Battle of the Yellow Sea. Li Hongzhang was even unaware of the Japanese landings in Korea.

Li Hongzhang compared himself to a "paperhanger," unable to fix the fundamental flaws in the Qing system—such as the feudal bureaucratic structure and outdated military command.

5. The Long-Term Consequences of the War: Reparations That Enriched Japan and Altered East Asia

After the war, the Qing Dynasty was forced to pay Japan 200 million taels of silver (with interest totaling over 300 million), a sum equivalent to more than three years of Japan's fiscal revenue.

  • Japan's Rapid Rise: 84.7% of the reparations were used to purchase warships and build a strong navy, which led to its rise to world-class status within ten years and its transformation into a militarist power (a path it pursued until World War II).
  • Shift in East Asian Power Dynamics: Japan replaced the Qing Dynasty as the dominant force in East Asia, and Taiwan was ceded (a issue that still affects the region today). Korea also broke free from Qing rule, contributing to the complexities of the Korean Peninsula.

Sha Qingqing notes that the consequences of the Sino-Japanese War are still felt today, with many current issues in East Asia having their roots in that conflict.

This report, through the story of the "Haiyan" ship and Sha Qingqing's research, illustrates that the war was not just a military defeat but a reflection of comprehensive weaknesses in systems, intelligence, and diplomacy. It not only changed the geopolitical landscape of East Asia at the time but also provides valuable lessons for the present day.
