Q&A: Where might records omit very large ancient armies?

Could India be a candidate for major battles missing from the record?

Indian records are judged comparatively good. Southeast Asia is suggested as a more plausible area of uncertainty because neighboring Chinese armies gave regional states reasons to mobilize large forces.

Surviving Indian records are judged comparatively good. Southeast Asia is proposed as a more plausible place to consider large forces that receive less attention. States living beside powerful Chinese armies had reasons to maintain substantial armies themselves. This regional comparison does not identify a particular lost battle.
