The 1st Battalion went from Gibraltar to the Iberian Peninsula and was at Roliça and Vimeiro in 1808.
The battalion took part in the Corunna, losing 400 men during the march.
The men were then shipped to UK before taking part in the Walcheren Campaign before returning to the Peninsula in 1812.
The regiment was present at Vitoria in 1813 and heavily engaged at the later action at Roncesvalles.
At the Heights of Echalar, in August 1813, Wellington watched the regiment's attack against 6,000 French in rugged positions in the mountains and described it as "The most gallant and the finest thing he had ever witnessed".
The regiment was held in reserve at the Nive and was again heavily engaged at Orthez in 1814.

In 1832, the 6th became a Royal Regiment and its title was changed to the Royal (1st) Warwickshire Regiment.
The 6th took part in the 7th and 8th Xhosa Wars in South Africa and helped suppress the Indian Rebellion in 1857.

The regiment was not fundamentally affected by the Cardwell Reforms of the 1870s, which gave it a depot at Budbrooke Barracks in Warwickshire from 1873, or by the Childers reforms of 1881; since it already possessed two battalions, there was no need for it to amalgamate with another regiment.
Under the reforms, the regiment became the Royal Warwickshire Regiment on 1 July 1881 and became the county regiment for Warwickshire (at the time including Birmingham) and encompassed its Militia and Volunteer Infantry.
Under these reforms, the regiment now consisted of the following battalions:
Regulars
1st Battalion in 1881 based in London
2nd Battalion in 1881 based in Jubbulpore
Militia
3rd (Militia) Battalion, based in Warwick, formerly the 1st Warwick Militia
4th (Militia) Battalion, based in Warwick, formerly the 2nd Warwick Militia
Volunteer Infantry
[Double-battalion] 1st & 2nd Battalions, 1st (Birmingham) Warwickshire Rifle Volunteer Corps, based in Birmingham, renamed as 1st Volunteer Battalion in 1883
[Double-battalion] 1st & 2nd Battalions, 2nd Warwickshire Rifle Volunteer Corps, based in Coventry, renamed as 2nd Volunteer Battalion in 1883
In 1898, the regiment fought at Atbara and Omdurman during Lord Kitchener's reconquest of the Sudan and saw service at Diamond Hill and Bergendal during the Second Boer War.
