racing, and won Champion 3-Year-Old honors. In the Horse of the Year poll, conducted by Turf and Sport Digest magazine, Assault received 110 voted to win the title from Armed, who received 37. Retirement Assault was originally intended to be retired after his four-year-old season and stand stud alongside his sire at King Ranch. However, none of the mares he was mated with became pregnant; it was apparent that he was sterile. He was returned to racing until the age of seven, where he won a few more races, including one more running of the Brooklyn Handicap. He was then permanently retired to King Ranch. There were some rumors that he was allowed to pasture breed with some of King Ranch's Quarter Horse mares, but there are no records that any of those foals made it to the track. He did sire two Quarter Horse foals, and they were registered with American Quarter Horse Association. Assault was euthanized after falling and breaking his left front leg at the shoulder, dying on September 1, 1971, at age 28. The grave site is on the King Ranch (in Kingsville, Texas). Honors Assault was inducted into the National Museum of Racing and Hall of Fame in 1964. In The Blood-Horse ranking of the top 100 U.S. Thoroughbred champions of the 20th Century, Assault was ranked #33.
