On this occasion, Bill Scott attempted to lead from the start and set a strong pace, but Attila began to weaken before the horses entered the straight and was soon beaten. He finished eighth of the seventeen starters behind Blue Bonnet, a filly described in the "American Turf Register and Sporting Magazine" as "a very inferior animal". Two days later Attila ran again in the Doncaster Cup against older horses over two and a half miles. He finished last of the four runners behind Beeswing, Charles XII and The Shadow. Later that afternoon he was allowed to walk over for the Gascoigne Stakes over the St Leger course and distance. Attila reappeared as a four-year-old in the Port Stakes, a race for four-year-olds at the Newmarket Craven meeting in April. He took the prize without having to run, as the other entrants were withdrawn and he was allowed to walk over. He did not appear on a racecourse again in 1843. After an absence of fourteen months, Attila returned for the Royal Ascot meeting in June 1844 where he ran twice. In the Royal Hunt Cup, a one-mile handicap race, he finished second to The Bishop of Romford's Cob, with the two finishing well clear of the other runners. The following day he ran in the Gold Cup but was never in contention at any stage and finished unplaced behind The Emperor (at that time running as an unnamed "colt by Defence"). He never ran again and was retired to stud. After a single season of retirement in England Attila was leased to Auguste Lupin and spent the 1846 season covering mares in France. The ship returning him to England encountered rough seas and Attila panicked, kicking his stall to pieces and sustaining serious injuries. He was taken ashore at London, but died shortly afterwards at Tattersalls, Hyde Park Corner. His only crop of French foals included the colts Saint Germain and Babiega, who finished first and second in the 1850 Prix du Jockey Club and the filly Fleur de Marie who won the Prix de Diane in the same year.
