Seabiscuit (May 23, 1933 - May 17, 1947) was a champion Thoroughbred racehorse in the United States. A small horse, Seabiscuit had an inauspicious start to his racing career, but became an unlikely champion and a symbol of hope to many Americans during the Great Depression. Seabiscuit has been the subject of numerous books and films including Seabiscuit: the Lost Documentary (1939); a Shirley Temple film, The Story of Seabiscuit (1949); a book, Seabiscuit: An American Legend (2001) by Laura Hillenbrand; and a film adaptation of Hillenbrand's book, Seabiscuit (2003) that was nominated for the Academy Award for Best Picture.
Injury and return
Seabiscuit was injured during a race. Woolf, who was riding him, said that he felt the horse stumble. The injury was not life-threatening, although many predicted Seabiscuit would never race again. The diagnosis was a ruptured suspensory ligament in the front left leg. With Seabiscuit out of action, Smith and Howard concentrated on their horse Kayak II, an Argentine stallion.  Seabiscuit and a still-convalescing Pollard recovered together at Howard's ranch, with the help of Pollard's new wife Agnes, who had nursed him through his initial recovery. Slowly, both horse and rider learned to walk again (Pollard joked that they "had four good legs between" them). Poverty and his injury had brought Pollard to the edge of alcoholism. A local doctor broke and reset Pollard's leg to aid his recovery, and slowly Pollard regained the confidence to sit on a horse. Wearing a brace to stiffen his atrophied leg, he began to ride Seabiscuit again, first at a walk and later at a trot and canter. Howard was delighted at their improvement, as he longed for Seabiscuit to race again, but was extremely worried about Pollard, as his leg was still fragile.  Over the fall and winter of 1939, Seabiscuit's fitness seemed to improve by the day. By the end of the year, Smith was ready to return the horse to race training, with a collection of stable jockeys in the saddle. By the time of his comeback race, Pollard had cajoled Howard into allowing him the ride. After the horse was scratched due to soft going, the pair finally lined up at the start of the La Jolla Handicap at Santa Anita, on February 9, 1940. Seabiscuit was third, beaten by two lengths. By their third comeback race, Seabiscuit was back to his winning ways, running away from the field in the San Antonio Handicap to beat his erstwhile training partner, Kayak II, by two and a half lengths. Under 124 pounds (56 kg), Seabiscuit equalled the track record for a mile and 1/16.  One race was left in the season. A week after the San Antonio, Seabiscuit and Kayak II both took the gate for the Santa Anita Handicap and its $121,000 prize. 78,000 paying spectators crammed the racetrack, most backing Seabiscuit. Pollard found his horse blocked almost from the start. Picking his way through the field, Seabiscuit briefly led. As they thundered down the back straight, Seabiscuit became trapped in third place, behind leader Whichcee and Wedding Call on the outside.  Trusting in his horse's acceleration, Pollard steered between the leaders and burst into the lead, taking the firm ground just off the rail. As Seabiscuit showed his old surge, Wedding Call and Whichcee faltered, and Pollard drove his horse on, taking "The Hundred Grander" by a length and a half from the fast-closing Kayak II. Pandemonium engulfed the course. Neither horse and rider, nor trainer and owner, could get through the sea of well-wishers to the winner's enclosure for some time.
