During the 17th and 18th centuries twelve regiments of Swiss mercenaries were employed in the French Royal Army, notably the Swiss Guards. During the 10 August riot of 1792, supporters of the French Revolution, including members of the radical-leaning National Guard marched on the Tuileries Palace. King Louis XVI escaped with his family, but, after fighting broke out in the palace courtyard, the Swiss Guards were massacred by the mob. Some Guards, including the commander, were captured, jailed, and later guillotined.
