Amidst the complexities of dynastic opposition and civil war during the later Jacobite era, the loyalties and material commitment of individuals were often in flux and have not always been so simple for historians to cleanly define. Allegations of significant Jacobite desertions have long been suspected (and more recently have been examined), but little scholarly enquiry has been made into cases of defection by soldiers within the government forces who were charged with quelling the Jacobite threat in Britain during the ’45.1 Resistance to martial service permeated both sides of the conflict, but deserting ranks to avoid combat is one thing, while joining up with the enemy is another entirely. Archival evidence shows us that soldiers in British service – including loyalist Highlanders on campaign in Scotland – deserted their units in smaller numbers than their Jacobite rivals, but incidents of soldiers breaking ranks was still a problematic issue for British army officers and Hanoverian officials.2 Digging deeper into the sources further reveals that some of these deserters found both cause and motivation to fight amidst the ranks of Jacobite rebels.
