summed up Henderson as follows: “Conceited, vain, self-opinionated, rigidly adhering to his preconceived ideas, he poured out telegrams, dispatches and letters in unbelievable numbers and of formidable length, repeating a hundred times the same ill-founded views and ideas. Obtuse enough to be a menace and not stupid enough to be innocuous, he proved un homme néfaste.”
