It seems likely now that the Henderson Brooks Report on the debacle in the border war with China, completed in 1963, will never be released. Furthermore, even if one day a stable, confident and relaxed government in New Delhi should, miraculously, appear and decide to publish it, the text would be largely incomprehensible, the context, well known to the authors and therefore not spelled out, being now forgotten. The report would need an introduction and gloss - a first draft of which this essay attempts to provide, drawing upon the author's research in India in the 1960s and material published later.
