Frederic Augustus Thesiger, 2nd Baron Chelmsford, (31 May 18279 April 1905) was a British Army officer who rose to prominence during the Anglo-Zulu War, when an expeditionary force under his command suffered a decisive defeat at the hands of a Zulu force at the Battle of Isandlwana in 1879. Despite this defeat, he was able to score several victories against the Zulus, culminating in the British victory at the Battle of Ulundi, which ended the war and partly restored his reputation in Britain. Early life Frederic Augustus Thesiger was born 31 May 1827, the eldest child of Frederic Thesiger, a lawyer who later became Lord Chancellor and was created Baron Chelmsford. Thesiger was educated at Eton College. Thesiger's great-uncle Sir Frederick Thesiger was aide-de-camp to Lord Nelson at the Battle of Copenhagen in 1801. Military career He wished to pursue a military career. In 1844, after unsuccessfully trying to obtain a place in the Grenadier Guards, he purchased a commission in the Rifle Brigade. He served in 1845 with the Rifles in Halifax, Nova Scotia before purchasing an exchange in November 1845 into the Grenadiers as an ensign and lieutenant. He was promoted to lieutenant and captain in 1850, and became aide-de-camp in 1852 to the Lord Lieutenant of Ireland, Lord Eglinton, and then to the Commander-in-Chief in Ireland, Sir Edward Blakeney, from 1853 to 1854. Crimean War In May 1855, he left for the Crimean War, in which he served firstly with his battalion, then as aide-de-camp from July 1855 to the commander of the 2nd Division, Lieutenant-General Edwin Markham, and finally as deputy assistant quartermaster general from November 1855 on the staff at Headquarters, being promoted to brevet major. He was mentioned in dispatches and received the fifth class of the Turkish Order of the Medjidie and the British, Turkish and Sardinian Crimean medals. Indian Rebellion of 1857 In 1857, he was promoted to captain and lieutenant colonel, and transferred (1858), as a lieutenant colonel, to the 95th (Derbyshire) Regiment of Foot, serving with that regiment at the end of the Indian Rebellion, for which he was again mentioned in dispatches. He served as deputy adjutant general to the forces in Bombay from 1861 to 1862, and was promoted to brevet colonel in 1863. There, he befriended the then governor of Bombay, Sir Henry Bartle Frere, and this relationship would be important later when serving in South Africa.
