The 32-14 victory saw the Black and Golds win the Division One South in this season’s County Championships.
Cornwall are reigning county cup champions after their 18-13 win against Lancashire last year. They are hoping this experience will see them carry off the trophy for a fourth time when they face Cheshire, who defeated Lancashire to become Division One North champions, in a repeat of the 1988 final.
Graham Dawe’s Cornwall side were helped to victory by Billy Searle’s hat-trick and although they always looked the stronger, it wasn’t until midway into the second half that Sam Matavesi broke through the Surrey defence and offloaded to Searle who went through for his third try which Shepherd converted to make it 27-14.
A try from Lewis Webb completed the scoring and sent the huge Trelawney Army support home happy – and planning another trip to London.
