The H-W book, controversies aside, was well written, the English was near-perfect and the prose lively (unlike many turgid histories I could mention).

If only Hofschroer had done the research, H-W the writing and Barbero the editing, with an eagle eye open for bias, then something approaching a definitive history might have been forthcoming. If wishes were horses...
