Profile

The story

Bred by August Belmont II, Man o' War was sold with Belmont's yearling crop while the breeder was involved in the First World War effort. Samuel Riddle bought the large chestnut for $5,000 on trainer Louis Feustel's advice. Johnny Loftus rode him through a dominant juvenile season in which he won nine of ten starts. His only defeat came at Saratoga after barrier disruptions, a poor start, and traffic; Upset prevailed by half a length.

With Clarence Kummer becoming his principal rider at three, Man o' War went undefeated in eleven races. Riddle intentionally bypassed the Kentucky Derby, sending him instead to victories in the Preakness, Withers, and Belmont. Later performances expanded his reputation across distances and under significant weight. He ended his career by defeating the older Triple Crown winner Sir Barton in Canada. At stud, Man o' War produced 64 stakes winners from 386 registered foals, including Triple Crown winner War Admiral, and his influence reached both racing and sport-horse pedigrees.

Editorial analysis

Why this horse matters

Man o' War established an American model for the racehorse as both elite athlete and mass cultural attraction. His record combines near-perfect consistency with performances from sprint distances through extended routes, often under weights that materially shaped the conditions. His story also requires era awareness: webbing barriers, timing, surfaces, and campaign patterns differed from modern racing. The strongest comparison is therefore dominance relative to contemporaries, weights carried, margins, and documented records rather than a fabricated modern speed number.

Reading the record

Research context

Technical and historical notes, presented as context rather than instruction.

  1. Starts used a webbing barrier rather than a modern starting gate, an important context for his lone defeat.

  2. Samuel Riddle deliberately skipped the Kentucky Derby; Man o' War did not fail to qualify for it.

  3. Early twentieth-century times, weights, and surfaces are not directly comparable to modern speed figures.

    List each sire, dam, and damsire recorded for Man o' War; open the linked source before carrying a relationship into another generation.

    Based on: Recorded pedigree fields
  2. Era comparison

    Start with Man o' War's recorded foaling year (1917). Date every comparison and keep later commentary separate from contemporaneous results.

    Based on: Recorded foaling year
  3. Connection map

    Trace the recorded breeder, owner, trainer, rider entries one source at a time. Preserve the role and date attached to each source rather than assuming a permanent relationship.

    Based on: Named connections, events, or honors
  4. Identity language

    Copy breed, studbook, sex, and place terms exactly as the source presents them; note conflicts instead of silently standardizing them.

01Bloodstock research

Profile-linked brief

Stud fee is a price tag, not a breeding verdict

The advertised fee opens a stallion dossier. Book size, opportunity, mare quality, crop age, contract terms, and the goals for the mating determine what the price can and cannot mean.

Why read this next: The editorial index explicitly connects this brief to Man o' War. Use its bloodstock research framework and 4 direct references as a method companion; the link does not add a new fact to the horse profile.
