Members of the congregation played an active part in the Battle of Sheriffmuir in 1715, fighting for the Old Pretender, whilst the rest of Glasgow supported the Hanoverian side. Some of the Jacobites fled; some had their estates confiscated. John Walkinshaw escaped from Stirling Castle by changing clothes with his wife, and made for the Old Pretender in Avignon; later he acted as the Prince's envoy in discussions for his marriage to Princess Clementina Sobieska. The congregation survived, depleted and impoverished, and subject to increasingly restrictive laws. In 1728 a meeting house was opened in Broad Close opposite the University, with Duncan (a college bishop since 1724) assisted by a Mr Wingate. This was soon closed by the magistrates and Wingate sent packing. Duncan, now an old man, held services in his own home until his death in 1733.
