Ruthless was a filly out of Eclipse and Barbarity. She was the first of 5 fillies from that combination. Her sisters included Relentless, Remorseless, Regardless, and Merciless. They were collectively called The Barbarous Battalion!. Ruthless was the first horse to win the Belmont Stakes in 1867, and one of only 2 fillies who have ever won the Belmont in over 100 years of the race's history. She was inducted into the Racing Hall of Fame in 1975, and has a race named after her at Aqueduct called "The Ruthless." Hailee and Violet are related to this macho girl through the following horses (and others): Orlando, Whalebone, Touchstone, Bay Middleton, Selim, Camel, and, of course, Eclipse!
