Helensburgh's best run in the Cup came in 1878–79. The club was awarded its tie with Heart of Midlothian F.C. after the Hearts refused to play a replay in accordance with the Scottish Football Association's instructions,[4] and beat Hibernian F.C. at the Powderhall ground,[5] on its way to the semi-finals, which, that season, had three clubs; unfortunately for the club, Helensburgh missed out on the bye to the final, and lost 3–0 at home[6] to a Vale of Leven side heavily backed by a local factory and de facto a professional side.
The following season, the club again lost to the Vale, and lost to Vale for the third year in succession - the regional nature of the draws making such repeat ties more likely - in 1880–81, two goals just before half-time contributing to a 4–1 defeat.[7]
The club's last entry to the competition came in 1881–82, losing in the fourth round to Arthurlie F.C. in a match spoilt by heavy wind.[8] The club folded during the season, thanks to crowds dwindling to the single figures, with competition from the successful Dunbartonshire sides in the vicinity,[9] and the club was struck off the register in August 1882.[10] The name was later used by at least three other clubs, including one founded in 1896 which became a member of the Scottish League.
