[1] His father was Major George Warburton, Inspector General of the Royal Irish Constabulary for Aughrim, County Galway.
This became his first book, The Crescent and the Cross, an account of his travels in 1843 in Greece, Turkey, Syria, Palestine and Egypt, and which fairly divided public attention with Kinglake's Eothen, which appeared in the same year, 1844.
Interest in England was centred in the East at the time, and Warburton had popular sympathy with Kinglake in his advocacy of the annexation of Egypt.
But, apart from this consideration, the spirited narrative of Warburton's adventures and the picturesque sketches of Eastern life and character were more than sufficient to justify the success of the book.
His most substantial work was a Memoir of Prince Rupert and the Cavaliers (1849), enriched with original documents, and written with eloquent partiality for the subject.
