In the 1954-55 Season, Cookstown won the Intermediate League Section B title under the captaincy of Gordon Henderson. Their success continued in the Sixties, with Captain Gordon Donaghy leading the Club into Senior League II, having won the Intermediate League Section A title the previous year Given such consistency and determination, it seemed inevitable that Cookstown would reach Senior League I, and this they did in 1975.
Since then, the Club has won every Senior honour at least once. During the Eighties, its most successful period, Cookstown won Senior League I, the Anderson Cup, the Kirk Cup and the Irish Senior Cup. In 1983 Raymond Acheson, the Club's most successful Captain during these golden years, led Cookstown to a Senior League I and Anderson Cup double. Then, in an epic 1987 Irish Senior Cup Final, Cookstown again led by Raymond Acheson beat the much-fancied Banbridge side 4-0 at Blaris, in what proved to be the last such Final played there on a grass pitch.
There were also disappointments for Cookstown in these years, and in 1980 they lost to Belfast YMCA in the Irish Senior Cup Final. However the clouds of defeat had a silver lining, and when YM were unable to represent Ireland in a European competition, Cookstown accepted the invitation with alacrity.
Fund-raising by the Club and the local community began in earnest, but Cookstown were taken aback learn that they would have to participate ii Qualifying Tournament in Zagreb, and if successful they could then proceed to the European competil in Rome.
In the event, Cookstown won the qualify tournament and went on to Rome where they won the Final after a series of nerve-wracking penalty-flicks ( Martin Sloan scored the first, goalie David Larmour saved a flick and with the score at 3-1 in Cookstown's favour; Bobby Hamilton coolly stepped forward to make it 4-1 for Cookstown, who thus became the first Club in Ireland to win a major European competition. In 1988 Cookstown were again in a European competition and finished 7th in Holland - the highest position that an Irish team had thus far achieved in premier division of European Hockey.
A bed-rock of the Club's success has been its close connection with the local High School which has supplied many gifted hockey players. In 1994 the School opened its sand-based astroturf pitch,and was the first Ulster school to do so. This facility will be an advantage for Cookstown pupils, and the School's victory in the 1996 Burney Cup may well be a portent of things to come.
Like many another Club, Cookstown has its personalities and distinguished players including Martin Sloan, who has played for Ireland 149 times and Captain in more than 100 games; Internationals David McManus, M. Burns, Geoff Hamilton, and accomplished goal-keeper David Larmour; stalwarts Dickie Harkness and Davy Black.
Sadly, the Club has suffered as well, and in October 1994, Nigel Cheevers died. An Annual Tournament for Clubs from North and South has been instituted in his memory, and it is fitting that the first winners of the Nigel Cheevers Memorial Tournament were his home Club.
The Club has a proud record since its foundation in 1951 and over the past 45 years it has made an important contribution to the game in Ulster and much further afield.
