Dewis made his City debut in a home game against West Brom in December 1933. Born in Burbage, he started his career at Stoke Golding before featuring for Nuneaton Town and joining City in 1933 - where he stayed until 1950.

The forward had a good goals-to-games ratio at the club, firing in 45 in 116 league appearances for the club. He also netted six in 13 FA Cup ties.

Dewis had strength, determination and good aerial ability but he was reaching his peak when war was declared. His wartime goal record was excellent, however, with a 62-goal return coming from the 81 games City managed to fit in during the wartime period. He also made guest outings for Leeds United, Sheffield United, Chesterfield and Yeovil at this time.

At one stage during 1940-41 he scored in ten successive City games, scoring 15 goals in total during that spell. It was unfortunate, therefore, that arguably his best footballing days were behind him when the war was over and football resumed. He was top-scorer in the 1946-7 campaign with 19 goals before moving on to become third-team coach in 1950.

Although his playing days were over Dewis couldn't keep away from Filbert Street and he remained on as kit man until 1983.
