cossack reappeared as a five-year-old in the two and a quarter mile tradesman's plate at chester on 2 may. the handicap attracted a field of twenty-nine runners and cossack was assigned 125 pounds, meaning that he had to concede weight to all but one of his opponents. the race was run at a slow pace and frank butler, riding cossack, found himself trapped behind a "ruck" of horses on the final turn. butler was forced to pull the horse to the wide outside and cossack produced a strong finishing run, but failed by a "half neck" to catch malton, a four-year-old to whom he was conceding thirty-one pounds.
