William Forbes was a Scottish professional footballer who played in the English Football League for Plymouth Argyle in the 1920s.[1] He played as a right back.[2]
Forbes was born in Denny, which was then in Stirlingshire, and played for the local club, Denny Hibernian,[1] before coming to England in 1911 to play for Plymouth Argyle, then a Southern League club. He made 250 appearances for the club in all competitions either side of the First World War.[2] Forbes played in Argyle's first game in the Football League, as the Southern League Division One clubs were absorbed to form the Football League Third Division for the 1920–21 season,[3] and went on to play 134 Football League games. Best remembered for his full-back partnership with Moses Russell – they played more than 180 games together – Forbes made his last appearance for Argyle in 1924[2] and then went to America to play for Fall River F.C.[1]
