The report contains multiple eye-witness accounts, and also includes a detailed description of international law and practice on the treatment of diplomatic staff, comparing the Japanese behaviour to other examples in both World Wars, including Britain's treatment of German consular staff in Glasgow on the outbreak of war in 1939.
