The 1837 Grand Liverpool Steeplechase was the second of three unofficial annual precursors of a Handicap Steeple-chase, later to become known as the Grand National Steeplechase horse race which took place at Aintree Racecourse near Liverpool on 4 March 1837 and attracted a field of four runners.
The Duke came to, and cleared, the same fence at the second attempt, continuing on to secure a long lead.
Zanga unseated his rider at the next fence and wasn't put back into the race once recovered.
Victory for The Duke was certain, barring a fall once the Trial fence was cleared for the second time and he was slowed to a mere trot long before passing the finishing post.
This in turn led to a popular, but incorrect, belief that the race was run over a course at Maghull and not Aintree, and became the official view held by Aintree when a board listing the winners of all previous Nationals was erected underneath the stands in 1894, stating that the races of 1837, and 1838 were run at Maghull.
