It was hoped that the return to the Third Division would be a short one and that Gerry McCabe would be the manager to help Dumbarton win an immediate promotion. Despite a slow start, by the end of December, Dumbarton were in pole position to claim at least one of the play off places in the league. However, the end of a successful loan spell for the club's top scorer - Stephen Dobbie - coincided with a slump in form and by the end of March a gap had opened up between the top four and the chasing group. Despite a run of 5 consecutive wins in April, 5th place would be the best that could be achieved 8 points adrift of East Fife in 4th.
In the Scottish Cup, an excellent away win over Second Division Raith Rovers was rewarded by a third round tie against Celtic. However it would be the Premier League side that would advance.
In the League Cup, Dumbarton had a decisive win over Second Division Stirling Albion, but it would be another Premier League side, Inverness Caledonian Thistle that would advance after a close fought second round tie.
Finally, it would be 'business as usual' in the League Challenge Cup, with another first hurdle fall, this time to Morton.
Locally, in the Stirlingshire Cup, Dumbarton won one and lost one of their opening group ties, and failed to progress to the final.
