Grant's obscurity before the war made him underestimated, not unqualified

Before the Civil War, Grant had washed out of a modest peacetime military career and struggled through a string of failed civilian ventures, at one point reportedly reduced to selling firewood on the streets of St. Louis to support his family — a personal low point that later critics would seize on as evidence of fundamental unfitness.

Chernow argues this reading gets the causality backwards: Grant's failures were largely failures of peacetime commerce and bureaucratic politics, environments that rewarded connections and salesmanship he didn't have, not failures of the specific competencies — logistics, discipline, decisive judgment under pressure — that war would actually require. The chaos of civilian business was simply the wrong test for his particular strengths.

When war came, those dormant qualities surfaced almost immediately: rapid promotion followed early successes in the western theater, as Grant demonstrated a willingness to act decisively where more cautious, socially connected officers hesitated. Chernow uses this arc to challenge a common bias — mistaking someone's failure in one context for proof they lack ability altogether. Takeaway: the wrong environment can hide real competence for years before the right one reveals it.
