Following the success of the previous season, it was manager Jim Chapman's goal to consolidate the club's position in the Second Division. However, Dumbarton were to be devastated before a ball was kicked with the death during the close season of the club captain, Gordon Lennon, from a motoring accident. Nevertheless, despite there being few changes to the playing staff, the league campaign started disappointingly with only two draws to show from the first six starts - resulting in the club propping up the rest of the league. It was, however, to be a temporary blip and although there was no consistency in performances, a mid-table sixth place was achieved in the end.
In the domestic cups, however, it was all bad news - no wins and no goals! In the Scottish Cup, local rivals Morton would be victorious in the third round, after a goalless draw.
In the League Cup, Dunfermline Athletic had no difficulty in seeing off Dumbarton in the first round.
Finally, it was no surprise that the League Challenge Cup would witness another first round exit, and it would be Morton again who would do the damage.
Locally, the Stirlingshire Cup was resumed, and after two penalty shoot out wins in the group fixtures, the trophy would return to Dumbarton following a win in the final over Stenhousemuir.
