Founded in 1897 by local school master W Powell, the club's first ground was on the banks of the River Severn in the region of the present West Wharf 2 of the Royal Edward Dock, there it remained for six seasons.

Nelmes joined Cardiff in 1973-74 and packed down with Alan Phillips and Mike Knill in an outstanding front-row that was the platform for another famous club triumph over the 1975 Wallabies.

On Friday 2 January 1953 he received a telegram informing him that he was to make his first team debut the following day against Harlequins at the Memorial Ground as a late replacement for Bert Macdonald.
At the end of this landmark campaign Bristol's Annual Report paid tribute to his work for the club both on the field and at numerous social functions.
Derek made his final first team appearance against Weston-super-Mare in November 1972, but even after that he turned out in the odd United game when required over the next couple of seasons.
