When English stallions were imported to add to the American Thoroughbred ancestry, stronger animals resulted. Gallant Fox, the 1930 Triple Crown winner, was a direct progeny of English influence. His size, 1,200 pounds, and height, 16.1 hands, headed American breeding in a new direction.
American Thoroughbreds thrived on the new mix of English and American lineage. Triple Crown winners began to sprinkle the landscape. There were three in the 1930s as the English lines of Sir Gallahad and Blenheim pulled their weight.
