The Forgotten Clash between Italy and Japan in China

Amid the complex alliances and betrayals of World War II, few episodes illustrate the disorder of the conflict as vividly as the unexpected encounter between Italian and Japanese forces in China. The story that unfolded in Tianjin in September 1943 is a striking example of how war transformed former allies into adversaries.

With the signing of the armistice between Italy and the Allies in September 1943, the global landscape shifted dramatically. The Italian government’s decision to break away from the Axis and seek peace with their former enemies provoked an immediate reaction from their ex-allies. The Japanese, who controlled vast areas in China, swiftly acted to ensure that Italian assets in regions under their control would not fall into Allied hands. Tianjin, a city under Italian administration since 1901, became the epicenter of one of the conflict’s most peculiar military operations.

The Italian sector of Tianjin was defended by the San Marco Battalion, the elite of Italy’s naval infantry. These soldiers, considered among the best in the Italian armed forces, had maintained the garrison in the city since the 1920s. Until then, relations with the Japanese had been cordial, with both forces coexisting within the complex web of alliances and occupations that characterized the foreign presence in China.

However, the September 1943 armistice changed everything. For the Japanese, Italy had betrayed the Axis cause, meaning that their forces in China needed to be neutralized or captured. When Japanese troops surrounded the Italian sector of Tianjin, the San Marco Marines faced a difficult choice: continue fighting alongside the Germans and Japanese or surrender and possibly face imprisonment or even death.

Some sources suggest that the Italians opted for a third option. Instead of immediately submitting to the Japanese demands, a unit of the San Marco Battalion resisted determinedly for about 24 hours, defending their positions against a former ally. This brief but significant resistance is a testament to the moral and strategic dilemma faced by the Italians in that confusing moment of the war.

After the surrender, the fate of the Italian soldiers in Tianjin was uncertain. Most were likely captured and detained by the Japanese, who now saw their former comrades as enemies. The resistance by the Marines, though short-lived, was an act of defiance in a scenario where loyalties had become fluid and treacherous.

Photographs from this episode, taken by Japanese photographers at the time, offer a rare glimpse of this little-known clash. Many of these photos, documenting the Italian presence in northern China between 1936 and 1945, have only recently come to light, made available by Kyoto University. These photographs, some of which had never been seen publicly, shed light on a forgotten chapter of the war, where alliances were broken, and survival depended on rapid adaptation to new realities.

The Tianjin episode exemplifies the complexities of World War II, where the lines of friendship and enmity were constantly redefined. The Italian Marines, who had served in harmony alongside the Japanese in China for years, suddenly found themselves isolated, forced to make decisions they could never have imagined when they first arrived in Tianjin decades earlier. This event is a reminder that, in times of war, loyalty is often a volatile concept, shaped by ever-changing circumstances.

While most of the World War II narrative focuses on the better-known battles and major powers, stories like that of the San Marco Marines in Tianjin reveal the vast and multifaceted nature of the conflict. They remind us that the war was fought on many fronts, some of which, like the Italian resistance on Chinese soil, remain largely unknown. By rediscovering these stories, we can gain a more complete understanding of the global impact and complexities of the conflict.
