The 2nd Battalion then joined the Army of Occupation in France where they would remain until 1816 when they returned home to the UK. In 1824, both battalions of the 3rd Foot Guards deployed to Dublin, Ireland, and in 1826, the 2nd Battalion deployed to Portugal until returning home in 1828. Also in 1826, the 1st Battalion deployed to Manchester during troubles there. In 1830, William IV ascended to the throne, and the following year gave the regiment a new name, the Scots Fusilier Guards.
