At the outbreak of the French Revolution the Swiss troops were, as at least nominal foreigners, still considered more reliable than their French counterparts in a time of civil unrest. Accordingly, Swiss regiments made up a significant proportion of the royal troops summoned to Paris by Louis XVI in early July 1789. A detachment of Swiss grenadiers from the Salis-Samade Regiment was sent to reinforce the garrison of the Bastille prison shortly before it was besieged by the mob. The Swiss and other royal troops were subsequently withdrawn to their frontier garrisons. Over the next years The Ernest Regiment in particular faced a series of clashes with local citizens, culminating in a two-day battle with Marseilles' militia in 1791. This indication of growing popular resentment against the Swiss caused the Canton of Berne to recall the disarmed regiment. Another Swiss regiment, the Chateauvieux, played a major part in the Nancy affair (mutiny) of 1790 and 23 of its soldiers were executed, after trial by their own Swiss officers. The Swiss Guard however remained loyal and was massacred on 10 August 1792, when the mob attacked the Tuileries Palace, although Louis XVI had already left the building. The eleven Swiss regiments of line infantry were disbanded under a decree passed by the French Assembly on 20 August 1792. Over three thousand Swiss soldiers transferred individually to French units and continued in service. However, many of the rank and file returned to Switzerland, where measures had to be taken to provide them with relief and reintegration into the rural society from which most had been drawn.
