Caroline Mary Luard (died 24 August 1908) was the victim of an unsolved murder, known as the Seal Chart Murder, after she was mysteriously shot and killed at an isolated summerhouse in a heavily wooded area near Ightham, Kent. Her husband, Major-General Luard, later committed suicide. It has since been suggested that John Dickman, who was hanged for killing a passenger on a train in 1910, may have been involved in her death.
Caroline Luard was born Caroline Mary Hartley in the last quarter of 1850, in Egremont, Cumberland, youngest daughter of Thomas Hartley of Gillfoot. In the summer of 1875 she married Charles Edward Luard and had two sons by him – Charles Elmhirst Luard, born in August 1876, and Eric Dalbiac Luard, born April 1878. Elmhirst was the surname of Charles Luard’s mother, while Dalbiac referred back to Charles’s ancestor, Louisa Dalbiac, who had married Captain Peter John Luard in about 1783.
Charles Edward Luard, born in Edinburgh in 1839, was eleven years older than his wife. At the time of his birth his father, Robert Luard, was a Captain in the Royal Artillery. Like many in his family, Luard was a professional soldier and had retired with the rank of Major-General in the Royal Engineers. He had done so despite an incident during his career that might have ruined his chances of promotion. This related to the defeat of British forces by the Zulu at the Battle of Isandhlwana in 1879, a reversal that was largely blamed on Colonel Anthony Durnford. However, it was rumoured that Durnford’s orders had been stolen from his body after the battle, in order to absolve Lieutenant-General Frederic Thesiger, 2nd Baron Chelmsford and other senior officers of incompetence.
The fight to re-establish Durnford's reputation was led by his brother, Edward Durnford; Durnford's fiancée, Miss Frances Ellen Colenso, daughter of John William Colenso; the Bishop of Natal; and Charles Edward Luard. Luard made himself party to a letter writing campaign, accusing fellow officers of a conspiracy to blacken Durnford’s name. He was subsequently court martialled and censured for his actions.
Luard had entered the army in 1857 and, in 1867, was executive officer in London during the Fenian disturbances. In the same year he wrote to the Commissioner of the City Police with a report on the defensive state of Newgate Gaol, following a visit there in the company of the Commissioner and the City Architect. The letter included a sketch plan for rebuilding part of the prison wall. He was involved in building the Household Cavalry barracks in Windsor and the United Services Recreation Ground in Portsmouth; it is also said that he devised the scheme for the rearmament of Gibraltar.
