[3] Inkerman's dam Crimea was a fast and precocious filly who won the Cheveley Park Stakes in 1963 and was a distant female-line descendant of the influential British broodmare Molly Adare.
Despite his lack of experience Inkerman started favourite but after racing close to the lead in the early stages he dropped away quickly in the straight and finished twenty-first of the twenty-five runners behind Shirley Heights.
He produced a much better performance than he had done at Epsom and finished fourth behind Shirley Heights, Exdirectory and Hawaiian Sound, beaten by less than a length and a half by the winner.
Seton Blake started second favourite ahead of the filly More So while the best of the other runners appeared to be the four-year-old Orchestra (winner of the John Porter Stakes).
Inkerman went to the front soon after the start and never looked to be in the slightest danger of defeat as he turned into the straight with a clear advantage and won by four lengths from Sexton Blake.
For his efforts in 1978, Inkerman was given a rating of 126 by the Independent Timeform organisation, making him even pounds inferior to their top-rated three-year-old Ile de Bourbon.
In the official International Classification he was rated six pounds behind Ile de Bourbon, making him the seventh-best three-year-old colt of the season in Europe.
