During the first Bourbon restoration of 1814–15, the grenadier companies of the by now under-strength four Swiss regiments undertook ceremonial guard duties in Paris. Upon Napoleon's return from Elba in 1815 the serving Swiss units were recalled to Switzerland on the grounds that a new contract signed with the government of Louis XVIII had now been rendered void. However, one composite regiment of Napoleon's Swiss veterans fought at Wavre during the Hundred Days. Upon the second restoration of the monarchy in 1815 two regiments of Swiss infantry were recruited as part of the Royal Guard, while a further four served as line troops. All six Swiss units were disbanded in 1830 following the final overthrow of the Bourbon monarchy.
