John Thomas Jones

Sir John Thomas Jones, 1st Baronet KCB (25 March 1783 – 26 February 1843) was a British major-general in the Royal Engineers who played a leading engineering role in a number of European campaigns of the early nineteenth century. Jones was regarded by Wellington and asked to advise on fortifications including the modernisation of the defences in Gibraltar. He was also notable as an English amateur cricketer who made six first-class appearances.

Sir John Thomas Jones was eldest of five sons of John Jones, esq., general superintendent at Landguard Fort, Felixstowe, Suffolk, and of Cranmer Hall, Fakenham, Norfolk, by his wife Mary, daughter of John Roberts of the 29th foot. He was born at Landguard Fort on 25 March 1783. Sir Harry David Jones was his brother. He was educated at the grammar school at Ipswich, joined the Royal Military Academy, Woolwich in the spring of 1797, received a commission as second lieutenant in the Royal Engineers on 30 August 1798, and embarked in October for Gibraltar. Jones advised on improvements for Gibraltar's fortifications including Parson's Lodge Battery and Wellington Front. He was appointed adjutant of the corps, and remained at Gibraltar four years. While at Gibraltar he was employed on the defences of the north front and in constructing the famous galleries; he also studied seriously, and became a good French and Spanish scholar. He was promoted lieutenant on 14 September 1800 and in 1842 he returned to England. There he was employed on the eastern coast in constructing defence works to oppose the threatened invasion, and in the following year in throwing up field-works from Widford to Galleywood Common (known as the Chelmsford lines), to cover London on that side.
