Here are eight facts you didn’t know about War Admiral, the most famous son of Man o’ War.
War Admiral Was Relatively Small Compared to Other Racehorses
War Admiral was only 15.2 hands tall and weighed about 960 pounds. This is relatively small compared to the average Thoroughbred that stands around 16 hands and typically weighs 1,000+ pounds.
Though he was small in stature, War Admiral had excellent conformation. The stallion had a neat, compact build that was similar to his maternal grandsire, Sweep. He inherited his height from his dam, who was under 15 hands tall, unlike his sire that was 16.2 hands. War Admiral was given the nickname “The Mighty Atom” as he was small yet dominant on the racetrack.
War Admiral Was Said to Have a Sweet Personality
War Admiral was known by the public to have a fiery temperament, just like his sire. At the starting gate, he was notorious for putting up a fight, which once even led him to get injured.
However, away from the loud crowds, flashing cameras and exciting racetracks, he was said to have a sweet personality. At home, he was much more relaxed and would enjoy taking long naps. His trainer, Conway, said he had a personality similar to his dam.
Samuel Riddle Was Unimpressed By Him as a Foal
When War Admiral was a young colt, his owner Riddle was not impressed by his small size. He tried to give the foal away to his nephew by marriage, Walter Jeffords.
However, though Jeffords liked the colt, he turned down the offer. He didn’t want any quarreling happening within the family if War Admiral turned out well. Lucky for Riddle, he ended up keeping the Thoroughbred and the move paid off, as he was immensely successful.

War Admiral’s Famous Race Against Seabiscuit Almost Didn’t Happen
One of War Admiral’s most memorable moments is his one-on-one matchup with Seabiscuit. However, the famous meet-up almost didn’t happen.
At first, Riddle did not consider it dignified to have War Admiral run against a horse like Seabiscuit. After lots of pressure, he finally agreed to the meet-up for a purse of $15,000. Riddle had one major condition though. The horses would not race out of a start gate, as War Admiral did not like them.
The two Thoroughbreds finally met on November 1, 1938, in the Pimlico Special for what was deemed the “The Match Race of the Century.” The media had made War Admiral seem like the villain and Seabiscuit the hero. To them, he had it all, leading a luxurious life, whereas Seabiscuit had to fight to get where he was.
People from all over came together to watch this unique matchup. In the exciting race, Seabiscuit came through as the underdog, beating the reigning Triple Crown champion by four lengths.
War Admiral Sired 40 Stake Winners
There was no doubt about it that War Admiral had a successful racing career, but his accomplishments didn’t stop there. After retiring in 1939, he went on to stand at stud.
The stallion stood at Faraway Farm until 1958, one year before his death. He sired a total of 373 named foals. Out of all of those foals, there were 251 winners and 40 stake winners.
War Admiral Has Famous Descendants
War Admiral was well known for being a leading sire of racing champions and a leading broodmare sire. He was the leading sire in North America in 1945 and the leading broodmare sire in North America in 1962 and 1964.
Many of his descendants have found the same success he did. Cigar, Seattle Slew, and Affirmed all share War Admiral in their pedigrees. Modern-day champions such as a Zenyatta and 2015 Triple Crown champion American Pharoh are descendants of the legendary racehorse. In fact, War Admiral shows up eight times in American Pharoh’s pedigree.
