A successful run in the Scottish Cup brought Dumbarton to their eighth semi final and their first ever meeting with Celtic.

An invitation to compete in the Greenock Charity Cup was accepted, but Dumbarton lost out to the hosts Morton in the final.

During the season, 28 'friendly' matches were played, including home and away fixtures against Vale of Leven, Dumbarton Athletic and Queen's Park.

Dumbarton continued to attract some of the best players in Scotland, and joining up this season were Dickie Boyle and Geordie Dewar.
