During the Victorian era, the regiment took part in the Crimean War, participating in the fighting at the Alma river, Inkerman, and Sevastopol. For their involvement in the Crimean War, four members of the 3rd Battalion received the Victoria Cross. Later the regiment fought at Battle of Tel el-Kebir during the Anglo-Egyptian War in 1882, and then the Mahdist War in Sudan, both during the 1885 Suakin Expedition and in 1898, at the Battle of Omdurman. During the Second Boer War, the 2nd and 3rd Battalions were deployed to South Africa, where they took part in a number of battles including the Battle of Modder River and the Battle of Belmont, as well as a number of smaller actions. In 1900, seventy-five men from the regiment were used to raise a fourth Guards regiment, known as the Irish Guards in honour of the role that Irish regiments had played in the fighting in South Africa.
