China Station knowledge of Japanese decisive-battle doctrine

Years of China Station reporting counter the idea that Britain would enter the war blind. From the 1920s onward, successive admirals repeatedly warned London that Japanese planning centred on a decisive fleet battle. Naval and Foreign Office personnel in the region also included Mandarin and Cantonese speakers who understood local politics and communications. That institutional knowledge could help Britain recognize the battle Japan wanted and force it to occur earlier or on less favourable terms. The same language and regional expertise would also support negotiations once blockade and battlefield pressure made a settlement possible.
